/dev/dsp is gone after a reboot - consistently. Whenever I execute quake3
there is no sound because "/dev/dsp" file doesn't exist.
However, I can consistently produce /dev/dsp by doing
nano -w .q3a/baseq3/q3config.cfg and changing the line
seta snddevice "/dev/dsp" to "/dev/dsp1". This causes the same error until I
revert to "/dev/dsp" in the file. Then there is a useful /dev/dsp.

Anybody know how to troubleshoot this one?

Check your setup as per http://www.gentoo.org/doc/en/alsa-guide.xml

In /etc/modules.d/alsa, ensure that you have this line:
alias /dev/dsp snd-pcm-oss
Then run "update-modules".

Try re-emerging udev and all the alsa packages you have installed, e.g.:
emerge udev alsa-lib alsa-utils alsa-oss alsa-headers alsa-driver

If you use alsa-driver, perhaps its "oss" flag needs to be set?

It sounds like the oss modules are only being loaded when you run
quake3, rather than at boot. Try this:

1. Reboot
2. Record the output of "lsmod"
3. Run quake3
4. Confirm that /dev/dsp now exists
5. Record the output of "lsmod", and look for changes from step 2

You may find that module "snd_pcm_oss" has now been loaded.

And so, Paul Bredbury just had to say ...

Mine is kernel based. Below is the LONG output of lsmod after
getting /dev/dsp, then booting, and then re-getting /dev/dsp:

You don't have snd_pcm_oss or snd_mixer_oss being loaded at boot, strangely.

Do you have these lines in /etc/modules.d/alsa:

alias char-major-14 soundcore
alias sound-slot-0 snd-card-0
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss
alias /dev/mixer snd-mixer-oss
alias /dev/dsp snd-pcm-oss
alias /dev/midi snd-seq-oss

(If you change the file, run "update-modules" after changing it.)

The easy way to make sure they are loaded at boot is to add to
/etc/modules.autoload.d/kernel-2.6:

snd_pcm_oss
snd_mixer_oss

And so, Paul Bredbury just had to say ...

Paul, That's just it - there is no /etc/modules.d/alsa ... alsa and oss
emulation are in the kernel.
From http://www.gentoo.org/doc/en/alsa-guide.xml, "Warning: The methods
shown below are mutually exclusive. You cannot have ALSA compiled in your
kernel and use media-sound/alsa-driver. It will fail."

Yes, if you have builtin or built modules for alsa in the kernel, then you
can't use the alsa-driver ebuild, the ebuild will check your current klernels
..config to check this, but the /etc/modules.d/alsa is part of alsa-utils,
which includes many usefull tools as alsamixer and amixer.

Noted should that not everyone is pleased with the old alsa drivers that is
included in the kernel, but want to use the latest one and therefore only
compile soundsystem support into the kernel and then emerge alsa-driver.

Fine, so load those modules manually! Put
modprobe snd-pcm-oss
into /etc/rc.local
Put snd-pcm-oss into /etc/modules (if Gentoo uses that). Run a script the
first thing you boot in to load snd-pcm-oss. There are a million ways to
make sure that snd-psm-oss is loaded before you run your game. Pick on. Use
it. Yes, it might be neat to figure out why gentoo is loading them. If that
is your hobby, persue it. If on the other hand you just want to play your
game, then use one of the suggestions.

/etc/modules.d/alsa is used to configure the alsa driver, regardless of
where the alsa driver was compiled from.

Info at http://gentoo-wiki.com/HOWTO_ALSA_sound_mixer_aka_dmix

Since you effectively have no oss setup, this explains why oss isn't
automatically started I suppose. I'm actually a little surprised that
alsa itself works without a config file.

And so, J.O. Aho just had to say ...

I find this interesting as we've had no sound problems until baselayout was
upgraded via emerge. I'll re-examine the alsa info as Paul, and the ever
patient Unruh, have pointed out.

Thanks all for helping. Let you know how it goes.
