I have an onboard sound card and a pci soundblaster 16

After having problems with crackly sound with the onboard I decided to turn it off in bios and just use the SB. I also recompiled kernel and alsa

I compilied alsa with:
alsa-driver 1.0.9rc4a
alsa-lib 1.0.9rc4
alsa-tools 1.0.9rc4
alsaconf 0.4.3b
alsa-oss-1.0.9-i486-1 (from linux packages)

my kernel is 2.6.12 with only sound support added, no built in alsa or oss as per alsa install instructions say


Now the problem I have is that some apps work with it and some don't and it also seems to depend on if I'm root or user:

gaim sounds work (but only if i use default built in - ie not a command using aplay)
xmms works as user
thunderbird sounds works as root not as user and still crackles grrr
aplay works as root not as user
real player works as root not as user

if I aplay a sound as user i get:

ALSA lib pcm_dmix.c:802snd_pcm_dmix_open) unable to open slave
aplay: main:533: audio open error: No such file or directory

but works fine as root.

So far I've tried:
#chown me /dev/audio /dev/dsp /dev/mixer
and also chowned all /sys/modules/snd/*

but nothing I've tried seems to work

Anyone know what I else I can chown or chmod to fix this?

SoundBlaster 16 works best using OSS

maybe try to make yourself a member of the audio group.
just edit the file " /etc/groups " ( as root ) and add your name in the " audio " line.
( for example see the line of the " users " group )

egag

still no luck I'm afraid

Recompiled alsa and somehow I've lost all /dev sound devices

probably needs udev-054

Just installed udev 58 from slack site but no change
I was chowning some things tho and must have messed something up badly I think

Does the sb module in /etc/rc.d/rc.modules work?

I built the kernel with no oss or alsa support so there is no sb module
I have now recompiled with oss support (sb built in) and sound is back but still cant get thunderbird to work with sound
looks like /dev sound devices are back too
maybe this is an issue that belongs on the thunderbird and realplayer support forums, although real was once working ok but now there is no sound and even volume changes dont stick

I am using a self compiled 2.6.12 with the current alsa compiled against it. To get sound to work I have to run a script that is either in or is created in the alsa-driver source directory called snddevices that appears to create the sound device files.

I have added a line to my /etc/rc.d/rc.M file to run it after it initialises alsa & this works fine

Still no change regarding thunderbird and real

I believe its a permission problems somewhere along the line

what are the permisions for /dev/dsp0 and /dev/mixer?

bash-3.00$ ls -l /dev/dsp
lrwxrwxrwx 1 root root 9 2005-07-21 23:59 /dev/dsp -> sound/dsp
bash-3.00$ ls -l /dev/mixer
lrwxrwxrwx 1 root root 11 2005-07-21 23:59 /dev/mixer -> sound/mixer
bash-3.00$ ls -l /dev/sound/dsp
crw-rw--w- 1 root audio 14, 3 2005-07-21 23:59 /dev/sound/dsp
bash-3.00$ ls -l /dev/sound/mixer
crw-rw--w- 1 root audio 14, 0 2005-07-21 23:59 /dev/sound/mixer



but I've tried chmod and chown'ing them with no apparent effect

Maybe you've a .asoundrc file in your home directory pointing to the disabled device.

Nope, but, I've just recompiled kernel with oss support, uninstalled alsa, reinstalled real player and it now works.
So, just thunderbird to fix

BTW is there an oss equivalent of the aplay prog?

*edit nm i found 'play'
