A NOTE has been added to this issue. ====================================================================== <https://bugtrack.alsa-project.org/alsa-bug/view.php?id=2320> ====================================================================== Reported By: mario_7 Assigned To: tiwai ====================================================================== Project: ALSA - driver Issue ID: 2320 Category: PCI - hda-intel Reproducibility: always Severity: minor Priority: normal Status: assigned Distribution: Kernel Version: kernel-2.6.17.7 ====================================================================== Date Submitted: 07-31-2006 00:41 CEST Last Modified: 07-31-2006 17:47 CEST ====================================================================== Summary: Almost no sound on Asus laptop with Realtek ALC861 Description: I have almost no sound on my Asus A6RP-AP002 laptop. Almost because it can be said that the sound is... But let me start from the beginning. I tried many things to get sound on my laptop. I tried alsa drivers from realtek website, alsa 1.0.11 and latest drivers from HG. Alsa 1.0.11 examined my chipset properly - ALC861, other found it as ALC660. None of them were working (no sound). 2 days ago I downloaded latest 2.6.17.7 kernel and compiled it with included alsa drivers (1.0.11rc4), sound chipset was examined properly, but still nothing... I started using various options with snd-hda-intel module. Built-in speakers are not working with any of options (model=3stack/3stack-dig/6stack-dig) but headphones are almost working... With model=3stack I can hear sound with headphones but only when I plug them into line-in jack. The sound is very very quiet and it's also with crackling noise... (Volume is set to maximum level). With model=6stack-dig situation is almost the same, except that the headphones are plugged into headphone jack and the same sound can be heard in only one headphone (the second one is just silent). The built-in microphone is working quite well (there is only not too loud squeal during records). Other options like posotion_fix=1/2 or single_cmd=1 are not changing anything (with posotion_fix=2 Ubuntu is not loading, X hangs when the login sound should be played). If anyone would like to help me and need any other information than those placed in this post and in attached file, just ask for them and I'll answer :) Hope someone smart will know how to fix everything :) ====================================================================== ---------------------------------------------------------------------- michaldemin - 07-31-06 16:44 ---------------------------------------------------------------------- I think that all these hda-intel soundcards are having similar problems. It's just some kind of routing problem, how the codec is routed to out/input jacks. It looks like the codec has predefined table of how the ports should be configured, perhaps this table should be altered for each laptop model ? EDIT: I have been able to output the sound through MIC input ;) well kinda strange, but i should read the datasheet more carefully ---------------------------------------------------------------------- tiwai - 07-31-06 17:47 ---------------------------------------------------------------------- Exactly. As default, the driver reads the pin configuration set up by BIOS and assigns the basic mixer elements according to that unless the predefined configuration is given in the driver code. Unfortunately, in many cases, the BIOS setup is broken, and in other many cases, the auto-configuration isn't perfectly matching with the actual state. In such a case, we have to write up the proper support code. BTW, the datasheet of ALC861 is available on Realtek's web site.
