Can you give more hints: about how to tune the ACPI boot ? (I have no idea at all). By way, I call Benq's tech-support. Because they don't support Linux for Benq S52, so no much valuable info from them, just they tell sound chip is Conexant CS20551 (maybe mis-hear, it should be CX20551).

Q: is it a AMC'97 chip? ---------------------------------------------------------------------- tiwai - 06-23-05 12:42 ---------------------------------------------------------------------- If the info is correct, yes, it sounds like an AMC97 chip.

I am willing to help in delivering a patch however I am not familiar with developing for alsa and the CX20551 is not even on the conexant website to look for documentation like with some of their other chips. ---------------------------------------------------------------------- Kooper - 03-15-06 06:39 ---------------------------------------------------------------------- The same hardware (BenQ Joybook S52), the same problem.

For the second point, make sure that you never load snd-intel8x0m (note 'm'), e.g. by removing the driver module file. Then, comment out the whole codes related with modem. ---------------------------------------------------------------------- Kooper - 03-15-06 11:53 ---------------------------------------------------------------------- > The first one is hard to fix without a proper h/w information.

The code to be fixed is likely in ac97_codec.c.

Regards BenQ Support" However I phoned them up later and got them to confirm that it is the CX20551 chip in this laptop. I then proceeded to contact Conexant from their website literature@xxxxxxxxxxxx however the delivery to this address fails. If someone in the US or Canada could contact them directly on a toll free number that would be appreciated.

I don't know if it is useful (for example, the first lines confirms that is a AC97 based driver) but is full of numbers that, I hope, can be useful for ALSA hackers. Drivers are here: http://www.benq.it/ServiceAndSupport/downloads/downloads.cfm?product=829&type=D ---------------------------------------------------------------------- kesiev - 04-15-06 12:33 ---------------------------------------------------------------------- Ok... is not too nice but I'm posting also the windows exported file about "multimedia" of the Benq S53w.y1 . Is in italian but I thing is quite readable for anyone. Notice that the IRQ is different from windows to linux. Dunno if is useful but I'm trying to provide as many information I can, as asked in this thread. EDIT: can be just an IRQ/Port address pointing error? EDIT: tried with some PCI configurations but with no luck (however I've seen that there are some IRQ problems with Benq S53). However, playing with alsamixer and any PCI setitng, I've found a configuration that, if used, makes a noise that changes while playing from the speakers. I'm sending the "alsamixer -f alsasound.conf store" resulting file. I hope it helps. ---------------------------------------------------------------------- fedukoff - 04-18-06 09:35 ---------------------------------------------------------------------- I'm using BenQ Joybook S53. Same problem. Gentoo Linux Kernel 2.6.16 Alsa 1.0.11rc5 Any hints? ---------------------------------------------------------------------- drseergio - 05-09-06 14:36 ---------------------------------------------------------------------- I am also a user of Benq (S53). Is this issue being proccessed, is it possible to fix it at all? ---------------------------------------------------------------------- rlrevell - 05-09-06 16:40 ---------------------------------------------------------------------- As tiwai has explained, more info about the hardware is needed to fix it. This will have to come from Benq. ---------------------------------------------------------------------- drseergio - 05-09-06 17:31 ---------------------------------------------------------------------- Benq will never reply :(, I know them. Their support is awful... Btw, audio chips are not made by Benq, they are generic from other manufacturers. Or not? As already mentioned - Conexant CX20551. I cannot believe that no documentation is available :(. ---------------------------------------------------------------------- rlrevell - 05-09-06 17:28 ---------------------------------------------------------------------- Yeah but the vendors modify them. snd-hda-intel is a real pain - it's so flexible that we get lots of bugs that only affect a specific laptop. If there's no chance of Benq helping someone will have to reverse engineer it ---------------------------------------------------------------------- drseergio - 05-09-06 17:41 ---------------------------------------------------------------------- Conexant does not provide information too? You mean reverse engineer the windows drivers? The chip is conexant for sure as it is obvious from windows inf file. Toshiba P100 uses this chip as well maybe it is possible to contact them? At least I will try. ---------------------------------------------------------------------- rlrevell - 05-09-06 17:49 ---------------------------------------------------------------------- Yes exactly, if Benq won't provide the hardware information needed to get it working someone must reverse engineer the Windows drivers. ---------------------------------------------------------------------- drseergio - 05-09-06 17:52 ---------------------------------------------------------------------- But probably no one will do this because it seems that this problem only occurs on this notebook and there aren't so many benq s53 linux users ;/. This is really disappointing as I wanted to use this machine on gentoo. ---------------------------------------------------------------------- rlrevell - 05-09-06 17:57 ---------------------------------------------------------------------- Sorry, I don't know what to tell you. When you buy a laptop with the intent of running linux on it it's important to check with other users that the hardware is supported and the vendor not hostile to Linux. ---------------------------------------------------------------------- drseergio - 05-09-06 18:00 ---------------------------------------------------------------------- Yes, I agree. Probably dual-boot is the solution and I will wait until the development of the driver becomes reality. I would help but currently I do not have enough programming skills. ---------------------------------------------------------------------- fedukoff - 05-09-06 18:33 ---------------------------------------------------------------------- I have bought this laptop because it was on sale with Linux (CD in a box, not preinstalled). It was for me the guarantor, that all is compatible. Who knew... Linux referred to Linpus 9.2. Installation of this miracle has come to full grief. ---------------------------------------------------------------------- drseergio - 05-09-06 18:44 ---------------------------------------------------------------------- Mine came with linpus too, strange, isn't it? Ships with linux but not supported. Btw, found this http://www.ubuntuforums.org/showthread.php?t=120070 . Can it be related to our S52/S53 as well? Or that guy has some other codec? ---------------------------------------------------------------------- fedukoff - 05-09-06 19:11 ---------------------------------------------------------------------- Have you Linpus Linux installed on your laptop? Look at http://www.linpus.com/PDF/HW_compalibility_list_LL92.pdf and http://www.linpus.com/PDF/HW_compalibility_list_LL93.pdf It is very interesting. Linpus 9.3 has row "INTEL 82801FB/FBM/FR/FW/FRW (ICH6 Fam ily) AC'97 Audio Co" in their compatibility list, but 9.2 not. ---------------------------------------------------------------------- rlrevell - 05-09-06 19:12 ---------------------------------------------------------------------- Yes it's probably related - it seems that sound does not work on any Benq notebook. You could try the OSS i810_audio module ---------------------------------------------------------------------- drseergio - 05-09-06 19:21 ---------------------------------------------------------------------- fedukoff, have you tried using linpus 9.3? ---------------------------------------------------------------------- fedukoff - 05-09-06 19:27 ---------------------------------------------------------------------- I have no Linpus 9.3. I have Linpus 9.2 CD which came with my laptop. And 9.3 is not for public download now. ---------------------------------------------------------------------- rlrevell - 05-09-06 19:28 ---------------------------------------------------------------------- If it does not work with the latest ALSA release then changing distros is not going to help ---------------------------------------------------------------------- drseergio - 05-09-06 19:30 ---------------------------------------------------------------------- rlrevell, do you think this distro may be using OSS? ---------------------------------------------------------------------- fedukoff - 05-09-06 19:39 ---------------------------------------------------------------------- I now have installed Linpus 9.2 I hear system beeps. I need to play a little to try listen the music. ---------------------------------------------------------------------- rlrevell - 05-09-06 19:42 ---------------------------------------------------------------------- No: snd_intel8x0 -> ALSA i810_audio -> OSS ---------------------------------------------------------------------- drseergio - 05-09-06 19:50 ---------------------------------------------------------------------- i810 audio is the driver for the same chip? http://www.ubuntuforums.org/showthread.php?t=111870 found this... Looks like people have many problems with HDA codec. ---------------------------------------------------------------------- fedukoff - 05-09-06 20:16 ---------------------------------------------------------------------- hmm. how to configure oss? (I want to try) ---------------------------------------------------------------------- rlrevell - 05-09-06 20:17 ---------------------------------------------------------------------- Sorry my previous post was incorrect - these systems do not have HDA codec, they use the older AC97 codec. And yes, snd_intel8x0 and i810_audio are drivers for the same chip. It's a long shot that i810_audio would work ---------------------------------------------------------------------- rlrevell - 05-09-06 20:19 ---------------------------------------------------------------------- Um, just unload the alsa modules and load i810_audio ---------------------------------------------------------------------- drseergio - 05-09-06 20:28 ---------------------------------------------------------------------- So, does the OSS work? ---------------------------------------------------------------------- fedukoff - 05-09-06 20:29 ---------------------------------------------------------------------- I have some problems with it... (I'm on Linpus) # modprobe i810_audio /lib/modules/2.4.20-8lp/kernel/drivers/sound/i810_audio.o: init_module: No such device Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters.

You did make sure to unload all snd-* modules first right? ---------------------------------------------------------------------- fedukoff - 05-09-06 22:07 ---------------------------------------------------------------------- I found oss not loads without alsa on kernel 2.6.16. But with alsa i810-audio loads without problem... But no sound... ---------------------------------------------------------------------- fedukoff - 05-10-06 15:58 ---------------------------------------------------------------------- Bad news: http://www.4front-tech.com/forum/viewtopic.php?t=743&highlight=benq ---------------------------------------------------------------------- rlrevell - 05-10-06 17:10 ---------------------------------------------------------------------- Just to clarify, you should bother Benq, not Conexant, if you want sound on these machines to work. If everyone who posts in this thread sends them an email they might notice. We aren't asking for Linux support, just the hardware details needed to get sound working. ---------------------------------------------------------------------- kesiev - 05-10-06 17:19 ---------------------------------------------------------------------- Clear. So let's take a significative Benq's mailbox and send everybody a "soundcard specs" request. (seems that they aren't friendly - someone asked infos before, as reported into this bugreport) Can someone provide a valid mail address? ---------------------------------------------------------------------- trava - 05-10-06 17:21 ---------------------------------------------------------------------- I just wrote to benq and I said we need hardware specification. I'm waiting for an answer... Everyone have to do the same thing and I hope we will obtain the information. ---------------------------------------------------------------------- trava - 05-10-06 17:25 ---------------------------------------------------------------------- I used this address http://bcc.benq.com/BCCFRONTUI/process/newcase.aspx ---------------------------------------------------------------------- fedukoff - 05-10-06 17:41 ---------------------------------------------------------------------- >From oss forum: (http://4front-tech.com/forum/viewtopic.php?p=3300#3300) some more info: they told me that it looks like the driver is using the modem for sound.

For us as BenQ Support we are not able to help you on this,because is more related to Marketing and sales issue. I will forward your request to the factory, but I cant guratee that you will get answer on this , since this is more related to other vendor ( connexant) product. Regards, BenQ Europe Support. ---------------------------------------------------------------------- fedukoff - 05-11-06 08:15 ---------------------------------------------------------------------- Please, read the latest post on OSS forum: http://4front-tech.com/forum/viewtopic.php?p=3300#3300 I'll try it today... ---------------------------------------------------------------------- JProgrammer - 05-11-06 08:42 ---------------------------------------------------------------------- Sounds like the external amplifier setting in alsa and like all the other settings nothing seems to change ---------------------------------------------------------------------- fedukoff - 05-11-06 08:45 ---------------------------------------------------------------------- Yes, but in OSS? ---------------------------------------------------------------------- fedukoff - 05-11-06 18:25 ---------------------------------------------------------------------- One more reply from BenQ: Please go to the website at www.conexant.com. Refer to the list of sales offices by selecting Worldwide Sales on left side of screen and contact the one nearest you. The Applications Engineers in that office will be able to assist you. Thank you. ---------------------------------------------------------------------- fedukoff - 05-12-06 08:14 ---------------------------------------------------------------------- Can somebody call to Conexant? I can't becouse no any offices in my country and my spoken English is extrimally bad, and no one of sales offices has email :) http://www.conexant.com/wwsales/ ---------------------------------------------------------------------- rlrevell - 05-15-06 14:49 ---------------------------------------------------------------------- Sorry, I don't understand your comment. ---------------------------------------------------------------------- fedukoff - 05-15-06 14:57 ---------------------------------------------------------------------- It is online russian-english translator. :) I want to know is there some news from conexant? ---------------------------------------------------------------------- rlrevell - 05-15-06 15:25 ---------------------------------------------------------------------- Well, since no one reported calling them, I would guess not. I really would not be too optimistic about this being fixed soon. They don't seem to care that their hardware doesn't work with Linux. I would look into an external USB audio device. ---------------------------------------------------------------------- fedukoff - 05-18-06 12:45 ---------------------------------------------------------------------- I ask many services of BenQ around the world for documentation. Answer is the same: "Dear Sir, Unfortunately we cannot give you any hardware documentation." Somebody have call to Conexant? ---------------------------------------------------------------------- fedukoff - 05-18-06 13:37 ---------------------------------------------------------------------- Is it usefull? http://www.linuxant.com/drivers/riptide/index.php ---------------------------------------------------------------------- fedukoff - 05-19-06 08:07 ---------------------------------------------------------------------- response from Linuxant: Hi, as far as I know, Conexant does not manufacture an AC97 bus, however, they manufacture modems that can connect to the AC97 bus and we provide the HSF modem driver that you can download at: http://www.linuxant.com/drivers/hsf/downloads-license.php for these modem devices. We do not provide an audio driver for a Conexant device that is attached to the AC97 bus. We do provide however the riptide driver, which is an audio driver for a PCI riptide device and it not related to the AC97 bus. Regards, Jonathan Technical specialist / Linuxant www.linuxant.com support@xxxxxxxxxxxx ---------------------------------------------------------------------- thoroughfare - 05-25-06 23:03 ---------------------------------------------------------------------- I tried calling Conexant's US documentation line from the UK - they seemed confused by: 1) That I'm from the UK 2) I was helping to make a Linux driver for their chip ...so I got redirected to someone (a lady, can't remember her name), and she was out of the office so just got her voicemail. Can someone else give it another shot? ---------------------------------------------------------------------- rlrevell - 06-02-06 17:54 ---------------------------------------------------------------------- Off topic. Please file a new bug and delete comment #0010049. This bug report is about BenQ laptops. ---------------------------------------------------------------------- thoroughfare - 06-02-06 19:29 ---------------------------------------------------------------------- Erm, I don't think his comment was really off-topic? I'm following this bug because I have the exact same chipset in my Packard Bell Easynote A2808.
