sound issue with 2.6.27.9 (and 2.6.28-rc*)

I've been experiencing an issue where I have no sound with my SB Audigy 2 and alsa since the latest stable and the latest 2.6.28-rc* kernels.
According to dmesg,  it is recognized fine (the 2.6.28 kernels use 1.0.18rc3, and 2.6.27.9 has the same version as previous versions)
and I have all my alsa software updated, and running alsamixer shows that it's using the right card, but yet I have no sound - I've checked all the
volume levels multiple times so it's not that, not that it should be changing at all from when it does work under 2.6.27.8... I've been researching this for awhile and yet all I can find that has changed in the kernel for the emu10k1 alsa driver was a

ALSA: emu10k1 - Add more invert_shared_spdif flag to Audigy models

and that was only since 2.6.28-rc4... Any ideas what this could be caused by? Does anybody else have this issue?

Re: sound issue with 2.6.27.9 (and 2.6.28-rc*)

if you're sure its an upstream issue (as it seems to be) then how about reporting it to http://bugzilla.kernel.org ?? Are tere any errors or anythiing at all however which may help ...

On the other hand, if you are sure it is that one commit you mentioned, u cud just apply patch in reverse (git format-patch  and git apply -R).

There are no errors or anything, or else I would report it

Are you selecting your device directly or using the default? If you are using the default the order might have changed and now something else is the default.
What's on your modules line in rc.conf? I've read about cases where you have to blacklist the snd_pcsp and/or pcspkr to have sound from other devices (the default device problem again).

Yes, in fact I don't even have pcspkr enabled... I checked the output difference of the commands "alsaconf -P" & "alsaconf -R" on 2.6.27.8 and .9 but there is basically no difference - there's no reason my sound shouldn't work.

Re: sound issue with 2.6.27.9 (and 2.6.28-rc*)

Try with aplay -l in my case I get

$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: SB [HDA ATI SB], device 0: ALC660-VD Analog [ALC660-VD Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: HDMI [HDA ATI HDMI], device 3: ATI HDMI [ATI HDMI]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

These are the built-in cards on my notebook, if I plug an usb headset then it gets to be card 2 but if I reboot with the usb headset pluged in then it is card 0 and the built-in ones are card 1 and card 2, maybe something similar is happening to you.

I can reverse the commit, are you OK with using the latest kernel though (i.e. 2.6.28-rc8)

I have tried it and I had sound just like with 2.6.27, crappy but I had sound, alsa doesn't go so well with my notebook sad
I'm considering to move to oss, it sounds so much better but the mixer is a bit puzzling tongue

i just use oss as output for everything, and yea alsa is much slower. and uses more cpu in a lot of casses.

I tested this with 2.6.27.8, 2.6.27.10, and 2.6.28-rc9 - All of them returned the exact same thing... again the ONLY thing that has changed for the emu10k1 alsa module is the invert_shared_spdif, yet there is no reason that should effect my sound at all since I don't even use spdif...

@ TjPhysicist
I would appreciate all the help I can get right now, I'm going to report this to kernel bugs even though there are no errors and no reason why my sound isn't working.

Re: sound issue with 2.6.27.9 (and 2.6.28-rc*)

I had the same issue on my Audigy 2 ZS, it was fixed in RC6 or so. But I did have to use a different analog jack than I was previously.
It also reverted the Analog/Digital Output Jack setting in alsamixer on my setup, which I had to mute again.

Also I only had this problem on my x86_64 install, it never reared its head on my x86 install for whatever reason roll

Its in my github, the kernel26 tree. Upstream, is a direct copy of the master branch in upstream (i.e. it is vanilla kernel from git). master, is my changed branch.


To build....(you need git package, *'s are comments)

$ git clone http://github.com/TjPhysicist/kernel26.git
$ cd kernel26
$ git checkout master
*git checkout master, if you want my version of the kernel with the fix you wanted
*git checkout upstream, if you want vanilla upstream kernel with no changes etc, perhaps your bug has been fixed?!
$ make mrproper
$ make menuconfig
*you know the rest....

Ah I appreciate all your help but it was a simple alsamixer switch, the one shazeal said.
