Sound problem, only one channel???

R00ts · 04-08-2005, 07:50 PM

I'm having a problem with my sound. I'm using ALSA and the onboard sound on this motherboard (RealTek ALC850 7.1 ch), The problem is that it seems to only want to play one audio stream at a time.

If I'm playing music on XMMS and I open a video with Xine, the video will play fine but with no audio. Instead xine is dumping a "xine_out.wav" file into my home directory. However if I stop XMMS and then play the video, it will work fine.

There's also issues with Macromedia Flash audio not working if other audio is playing.

Finally the audio that I wrote for the game in my sig won't work on my machine, and this is the first time that I've heard anyone say it didn't work. it spits out one of two errors, depending on if xmms is playing or not.

- With XMMS playing:
ERROR: Could not initialize mixer audio: No available audio device

- With no XMMS playing:
- open /dev/sequencer: No such device

So I checked /dev/sequencer:

Code:

roots@harima:~/dev/allacrost/dev_build$ ls -l /dev/sequencer*
crw-rw----  1 root audio 14, 1 2005-03-13 17:38 /dev/sequencer
lrwxrwxrwx  1 root root     10 2005-03-13 17:38 /dev/sequencer2 -> /dev/music


roots@harima:~/dev/allacrost/dev_build$ ls -l /dev/music 
crw-rw----  1 root audio 14, 8 2005-03-13 17:38 /dev/music

Can someone help me figure out how to resolve this issue? I'm not quite sure what to do. Thanks.

EDIT

I forgot to mention I tried running alsaconfig, but that didn't resolve the issue.

I fixed the problem. I made a .asoundrc file in my home directory with the following:

Code:

pcm.card0 {

type hw

card 0

mmap_emulation true

}

pcm.!output {
type dmix
ipc_key 1234
ipc_key_add_uid 1
slave {
pcm "card0"
period_time 0
period_size 1024
buffer_size 32768
rate 48000
}
bindings {
0 0
1 1
}
}

#
# DSNOOP output device
#
pcm.!input {
type dsnoop
ipc_key 4321
ipc_key_add_uid 1
slave {
pcm "card0"
period_time 0
period_size 1024
rate 48000
}
}

#
# ASYM duplex device
#
pcm.!duplex {
type asym
playback.pcm "output"
capture.pcm "input"
}

#
# Make the duplex device default
#
pcm.!default {
type plug
slave.pcm "duplex"
}

#
# OSS Compability

pcm.!dsp0 {
type plug
slave.pcm "duplex"
}

ctl.!mixer0 {
type hw
card 0
}

As I understand it this specific code will only work with onboard Intel/nVidia audio. And now the audio for my game works again as well. Hurray!

Just postin' to thank you

I had the same issue, and the solution worked!

For the curious, I'm runnin' Xubuntu Feisty on kernel version 2.6.20-15-generic.
