Description Philip Hazel 2003-12-11 01:49:50 UTC
I upgraded my 2.4.20 kernel to the latest gentoo source (linux-2.4.20-gentoo-r9),
emerged alsa-driver, and then had no sound. Everything seems to work; just that nothing comes out of the speakers. I noticed I had a new version of alsa-driver (0.9.8). Unmerging alsa-drivers and downgrading to alsa-driver 0.9.2 fixes the problem. My sound card is:

  Bus  0, device  31, function  5:
    Multimedia audio controller: PCI device 8086:24d5 (Intel Corp.) (rev 2).
      IRQ 3.
      Non-prefetchable 32 bit memory at 0xfebff800 [0xfebff9ff].
      Non-prefetchable 32 bit memory at 0xfebff400 [0xfebff4ff].

Reproducible: Always
Steps to Reproduce:
1. emerge alsa-driver 0.9.8
2. reboot
3. play some audio

Actual Results:  
Audio applications ran perfectly, but no sound is heard.

Expected Results:  
Made some noise!

do you use modules ?
Comment 2 Philip Hazel 2003-12-11 02:05:45 UTC
Yes, alsa-driver installs a number of sound modules. I arrange to autoload them
at boot time.
Comment 3 Maarten Wisse 2003-12-11 04:06:25 UTC
I feel the bug report is not entirely accurate. I had similar problems. On my install, KDE says that /dev/dsp doesn't exist and fails to load the mixer. But when I start mplayer to play some sound file in a Konsole terminal, it works and sound comes out. Modules are also loaded appropriately. However, /dev/sound is empty, which it is only with 2.4 kernel, and not with 2.6.0-test11.
Comment 4 Philip Hazel 2003-12-11 05:45:36 UTC
I am not running KDE (I am using vtwm, if that matters). I believe my report is
accurate. The facts are: alsa-driver 0.9.2 works, but alsa-driver 0.9.8 does not,
with everything else being the same. I tried a number of sound-producing programs,
including mplayer, realplayer, and timidity.
Comment 5 Martin Holzer (RETIRED) gentoo-dev 2003-12-15 15:21:54 UTC
could you try rc1 or rc2 of alsa ?
Comment 6 Philip Hazel 2003-12-16 02:40:16 UTC
How do I do that? "emerge -s alsa-driver" just shows 

Latest version available: 0.9.8

without any rc1 or rc2, and

emerge -p =media-sound/alsa-driver-0.9.8-rc2

(or rc1) finds nothing.
Comment 7 Martin Holzer (RETIRED) gentoo-dev 2003-12-17 05:09:21 UTC
emerge /path/to/foo/bar.ebuild
Comment 8 Philip Hazel 2003-12-17 05:35:09 UTC
You mystified me there, but eventually I twigged that the source for the rc
versions were in the portage directories along with the other sources. At least
they are on my machine here at work - but this has no sound output. It will 
probably be the weekend before I can try your suggestion on my home machine where
the problem lies - not least because I'll need to allow plenty of time to put the
working version back afterwards if the rc versions fail. I will report the results
of the test in due course. Thanks for continuing to work with me on this.
Comment 9 Philip Hazel 2003-12-20 04:40:16 UTC
I am sorry to have to report no success with alsa-driver-1.0.0_rc1 or _rc2. I did the following:

1. unmerge alsa-driver (followed by reboot to check I had no sound).
2. emerge /usr/portage/media-sound/alsa-driver/alsa-driver-1.0.0_rc1.ebuild
3. reboot - no sound
4. unmerge alsa-driver
5. emerge /usr/portage/media-sound/alsa-driver/alsa-driver-1.0.0_rc2.ebuild
6. reboot - no sound
7. unmerge alsa-driver
8. emerge =media-sound/alsa-driver-0.9.2
9. reboot - Sound!

Please let me know if there's anything more I can do to help, but note that
I am going to be away from Jan 5th to Jan 29th.
