Slackware audio problem

Hi, I just erased everything and installed slackware 10.2. I have a problem with my audio, It works fine, but it seems that only one program can use the soundcard at one time. For example, if i'm using xmms, gaim doesn't make any sounds. And also, when I reboot, my volume settings (PCM, Master, etc) reset to 0. Any ideas? My soundcard is an integrated AC'97
Thanks in advance.

have you run
alsamixer
set the volumes, then run
alsactl store

Create ~/.asoundrc with the content :

Code:

pcm.!default {

        type plug

        slave.pcm "swmixer"

}



pcm.swmixer {

        type dmix

        ipc_key 1234

        slave {

                pcm "hw:0,0"

                period_time 0

                period_size 1024

                buffer_size 4096

                rate 44100

        }

}

You could change rate to 48000 depending on your hardware

Thanks, I'll try both suggestions tonight when I get home. But as keefaz said, it would be nice to know what that file does.

Additionally, artsd will interfere too. In KDE go to the (kcontrol) Control Center->Sound and Multimedia and find the control that says something like "disable artsd after so many seconds". The default is 60, set to 5.
Sorry I can't be more specific, I'm at work (no linux).

I don't have kde installed, I installed dropline gnome. Is there another way to do that from the command line or within gnome? Perhaps I don't have arts installed (It comes with kde doesn't it?)

This file enables some alsa settings for the sound card

Here it is supposed to enable the dmix plugin which is capable to
receive multiple audio flux sent by the applications and mix them
to the sound card

interesting
how do i tell what rate my card runs at?

Take a look at /proc/asound/card0/codec97#0/ac97#0-0
(or at least navigate into /proc/asound/card0 and try to grab some
infos from here)

ok mine says 48k
so would that be 48000 or 49152

dive	11-23-2005 04:37 PM

48000 i believe

but thats probably the max it can go - i think most cards use 44100 as default(?)

So I finally got home... alsamixer and alsactl store solved the first problem, thanks :).
But I did what keefaz said, then rebooted and my soundcard still can't be accessed by more than one program. :confused:

malodemickey, did you placed that file on the home of your current user (the one running the programs with sound)? Remember ~ means home folder, like /home/user.
