The following issue has been ASSIGNED. ====================================================================== <https://bugtrack.alsa-project.org/alsa-bug/view.php?id=2137> ====================================================================== Reported By: stdpikachu Assigned To: jcdutton ====================================================================== Project: ALSA - driver Issue ID: 2137 Category: PCI - emu10k1 Reproducibility: always Severity: minor Priority: normal Status: assigned Distribution: Gentoo Kernel Version: 2.6.15, 2.6.16 ====================================================================== Date Submitted: 05-20-2006 15:23 CEST Last Modified: 07-18-2006 14:35 CEST ====================================================================== Summary: No mute controls for Audigy or Audigy 2ZS Description: The problem has been around for while, but have only just got around to reporting it (incidentally, where do I search for previously file bug reports?). I have three computers, all with various flavours of Audigy cards, all using the latest emu10k1 alsa driver. The problem also exists with the in-kernel audigy driver. Googling for other people with the same problem suggests the problem crept it quite a while ago. No matter what UI is used, I can't mute most channels provided by the audigy driver. For instance, in alsamixer I can only mute Headphones, Line, CD, Phone, PC Speaker and Aux. ALl other channels are without mute toggles. The upshot of this is that mute controls in almost all alsa apps doesn't work and the only way to mute the channel is to manually set master or PCM volume to zero. I read of a bug with one of the intel sound drivers that lost most of the mute controls, maybe this is the same sort of thing. ====================================================================== ---------------------------------------------------------------------- pzad - 05-20-06 16:09 ---------------------------------------------------------------------- AFAIK Audigy alsa driver never had mute switches (sb live had). Only analog mixer part has mute switches. ---------------------------------------------------------------------- stdpikachu - 05-20-06 16:47 ---------------------------------------------------------------------- What does that mean in terms of giving emu10k1 mute functionality? It isn't possible? ---------------------------------------------------------------------- jcdutton - 05-20-06 17:02 ---------------------------------------------------------------------- Of course it is possible. It is just that time is spent on other things instead. ---------------------------------------------------------------------- rlrevell - 05-20-06 17:22 ---------------------------------------------------------------------- Wasn't it a deliberate design decision not to waste GPRs on mute controls, as this can be implemented by the mixer app? ---------------------------------------------------------------------- jcdutton - 05-20-06 17:27 ---------------------------------------------------------------------- One does not have to use GPRs to implement it. One can just use local state variables instead. ---------------------------------------------------------------------- pzad - 05-20-06 17:32 ---------------------------------------------------------------------- Simpler is waste GPRs. Audigy has plenty of GPRs to waste :-). Mute on every controls needs 54 GPRs - there will be more then 256 GPRs free after implementing them. ---------------------------------------------------------------------- pzad - 05-20-06 19:57 ---------------------------------------------------------------------- Could you try this audigy_mute.patch ? Not very much tested, but for me it works. Need some work to support cards with 1361T chip (I don't have such card - someone else have to finish it. ---------------------------------------------------------------------- rlrevell - 05-20-06 21:17 ---------------------------------------------------------------------- pzad, did you forget to upload the patch? ---------------------------------------------------------------------- pzad - 05-21-06 11:41 ---------------------------------------------------------------------- Sorry. It is there now. ---------------------------------------------------------------------- stdpikachu - 05-24-06 21:45 ---------------------------------------------------------------------- Apols for the numpty reply, but what are the instructions for patching the driver source? I've not done much kernel haXx0ring myself. I tried patch -p0 against emufx.c, but when that fails I'm a little bit lost...! Thanks for devoting the time and effort into all of this :) P.S. Is the 1361T chip the one inside the Audigy LS? ---------------------------------------------------------------------- pzad - 05-24-06 22:33 ---------------------------------------------------------------------- I think 1361T is in Audigy 4. The simplest way is: Get alsa-driver package - from www.alsa-project.org. extract it somewhere change dir to alsa-kernel dir in (should be in "somewhere" dir) patch -p1 < path_to_patch configure make make install restart alsa (/etc/init.d/alsasound restart) Issue History Date Modified Username Field Change ====================================================================== 05-20-06 15:23 stdpikachu New Issue 05-20-06 15:23 stdpikachu File Added: alsamixer.png 05-20-06 15:23 stdpikachu Distribution => Gentoo 05-20-06 15:23 stdpikachu Kernel Version => 2.6.15, 2.6.16 05-20-06 16:09 pzad Note Added: 0009884 05-20-06 16:47 stdpikachu Note Added: 0009885 05-20-06 17:02 jcdutton Note Added: 0009886 05-20-06 17:02 jcdutton Status new => acknowledged 05-20-06 17:22 rlrevell Note Added: 0009887 05-20-06 17:27 jcdutton Note Added: 0009888 05-20-06 17:32 pzad Note Added: 0009889 05-20-06 19:57 pzad Note Added: 0009891 05-20-06 21:17 rlrevell Note Added: 0009892 05-20-06 21:18 rlrevell Note View State: public: 9892 05-21-06 11:32 pzad File Added: audigy_mute.patch 05-21-06 11:32 pzad Note Added: 0009897 05-21-06 11:41 pzad Note Edited: 0009897 05-24-06 21:45 stdpikachu Note Added: 0009960 05-24-06 22:33 pzad Note Added: 0009961 07-18-06 14:35 jcdutton Status acknowledged => assigned 07-18-06 14:35 jcdutton Assigned To => jcdutton ====================================================================== ------------------------------------------------------------------------- Take Surveys.
