Debian Sid Sound Problem

rockymaxsource · 09-18-2006, 04:53 AM

Hey,

I'm using Debian sid on my Dell inspiron 2200 laptop.

It seem everytime I start vlc I need do alsaconf. If I did not do that I would get this error,

Code:

over@YUNNAN:~$ VLC media player 0.8.5 Janus
libdvdnav: Using dvdnav version 0.1.10 from http://dvd.sf.net
libdvdread: Encrypted DVD support unavailable.
libdvdread: Couldn't find device name.
libdvdnav: Can't read name block. Probably not a DVD-ROM device.
libdvdnav: Unable to find map file '/home/lover/.dvdnav/.map'
libdvdnav:DVDOpenFilePath:findDVDFile /VIDEO_TS/VIDEO_TS.IFO failed
libdvdnav:DVDOpenFilePath:findDVDFile /VIDEO_TS/VIDEO_TS.BUP failed
libdvdread: Can't open file VIDEO_TS.IFO.
libdvdnav: vm: faild to read VIDEO_TS.IFO
ALSA lib pcm_dmix.c:862:(snd_pcm_dmix_open) unable to open slave
[00000434] oss audio output error: cannot open audio device (/dev/dsp)
[00000434] main audio output error: couldn't find a filter for the conversion
[00000434] main audio output error: couldn't create audio output pipeline

Plus, As long as my vlc works, I could not using skype or any other apps giving sound. If I try to use other audio apps I got this error

Code:

lover@YUNNAN:~$ /dev/dsp-1: Device or resource busy

Can any of you tell me what should I do so that I do not need to do alsaconf before I could listen to the musice? And I could use 2 audio apps at the same time so that I can listen to the music and if some one send me the Instant message via skype or amsn, I could get alarmed please?

Thanks,
Rocky

alsactl can store its preferences, but that shouldn't be needed since alsamixer should do this in SID anyway...

For multi sound streams you need a sound mixer.
The one that comes with ALSA is Dmix:
http://alsa.opensrc.org/index.php?page=DmixPlugin

For simply getting OSS support under ALSA, run:
modprobe snd_pcm_oss

The "Device or resource busy" message only means that an other sound app is blocking your sound mixer.
Just kill it:
killall -9 esd
If you're not using GNOME, replace esd with whatever you use.

Thanks very much for your reply!

I ran the following commands

Code:

YUNNAN:# modprobe snd_pcm_oss
YUNNAN:# dpkg -l | grep Dmix

Is there a command I can use to test weather my Debian system supports multi streams audio?

I'm using KDE, instead of

Code:

killall -9 esd

what is the command I should run please?

Thanks a lot in advance!
