Subject: ALSA configures okay, but I still get no sound. I am not getting any sound from ALSA. The modules load okay, and I used a mixer to unmute the channels and turn them up without any problems. But I am still getting no sound. I am currently using the modules included in the 2.6.10-gentoo-r6 kernel, but have also tried the ones from 2.6.11-gentoo-r4 and alsa-driver 1.0.8. Additionally, the ones from 2.6.11 and alsa-driver do not have a master channel. I can go into alsamixer and unmute it, but can't change the volume. On the 2.6.10 ALSA drivers, the channels that should be there are there, but even when they're unmuted and turned up, I still hear no sound. I have an on-board sound adapter, which is an SiS SI7012 and has a C-Media CMI19761 chipset. I am also using udev, and here are the device files udev creates. ls -la /dev/snd total 0 drwxr-xr-x 2 root root 0 Mar 23 16:31 . drwxr-xr-x 24 root root 0 Mar 23 17:31 .. crw------- 1 kenny audio 116, 0 Mar 23 17:31 controlC0 crw------- 1 kenny audio 116, 32 Mar 18 09:39 controlC1 crw------- 1 kenny audio 116, 8 Mar 18 09:39 midiC0D0 crw------- 1 kenny audio 116, 9 Mar 18 09:39 midiC0D1 crw------- 1 kenny audio 116, 10 Mar 18 09:39 midiC0D2 crw------- 1 kenny audio 116, 11 Mar 18 09:39 midiC0D3 crw------- 1 kenny audio 116, 24 Mar 23 17:31 pcmC0D0c crw------- 1 kenny audio 116, 16 Mar 23 17:31 pcmC0D0p crw------- 1 kenny audio 116, 25 Mar 23 17:31 pcmC0D1c crw------- 1 kenny audio 116, 56 Mar 18 09:39 pcmC1D0c crw------- 1 kenny audio 116, 48 Mar 18 09:39 pcmC1D0p crw------- 1 kenny audio 116, 57 Mar 18 09:39 pcmC1D1c crw------- 1 kenny audio 116, 1 Mar 23 17:31 seq crw------- 1 kenny audio 116, 33 Mar 23 17:31 timer I have no mixer problems (other than having no master channel on kernel 2.6.11 and alsa-driver 1.0.8), and the alsaconf utility even picks it up and says to use the snd-intel8x0 module. (I've also tried snd-cmipci with no success.) But I'm just not getting sound. Is my sound adapter just not supported, or could there be something else wrong? Why would ALSA be detecting my sound card and the mixer be working okay, but I still don't hear any sound? Also, I saw other bugs in which users downgraded to alsa-driver 0.9.2 and the problem was fixed, but 0.9.2 is no longer in the portage tree. Is there still a way I can get it (maybe someone still has an ebuild on hand or something), or what other options do I have (other than converting to OSS, which does work okay, or getting a new sound card)? Thanks. Reproducible: Always Steps to Reproduce: 1. Install a 2.6 kernel and configure it with ALSA as modules, or get alsa-driver 1.0.8. Build the kernel if you downloade it. 2. Get alsa-utils and alsa-tools. 3. Run alsaconf, and see that it detects an SiS sound adapter and suggests the intel8x0 module. Either let it modify /etc/modules.d/alsa or (preferably) modify it yourself accordingly. 4. Run alsamixer and unmute and turn up the master channel or other channels. If you're using 2.6.11 or alsa-driver, you'll see that the master channel and some others can't be turned up. 5. Add alsasound script to boot runlevel (rc-update add alsasound boot). 6. Reboot, run the alsasound script mentioned above with the stop argument and rerunit with start argument, or use alsactl store to save mixer settings. Actual Results: ALSA configures okay, and the mixer channels are unmuted, and it even detects my sound card and selects the appropriate module, but I hear no sound. Expected Results: DUH!!! :) Same as above, but I should hear sound.

I have this problem too. Everything worked fine with gentoo-(dev-)sources-2.6.9 and older until I upgraded to gentoo-sources-2.6.11-r3.
I experienced this with 2.6.11-r6, but reverting to kernel 2.6.10-r6 worked for me.
Can you please try reproducing this with any media-sound/alsa-driver release. If it's a problem with 1.0.9_rc2, then please report this upstream as I lack the hardware to reproduce this myself. http://bugtrack.alsa-project.org
I now compiled kernel linux-2.6.11-gentoo-r7 without ALSA built-in, rebooted with the new kernel, emerged alsa-driver 1.0.9_rc2, rebooted again and everything worked (after unmuting some channels with alsamixer). Note snd_intel8x0 is listed to load as a kernel module or it would probably not have worked. Seems like this is a problem with the ALSA version (1.0.8) in the kernel. Fixed for my part.
Thanks for the update, PC_Freak!
