xmms2 "Couldn't open device: hw:0,0"
 

Hello to everybody.

I was googling a lot but did not find any solution for my problem.
The problem is next. I've seen that xmms2 consumed too much CPU usage and changed the alsa.device config to hw:0,0
everything was good, xmms2 played music and xmms2d stopped to abuse CPU.

But today I wanted to start xmms2 and it have crashed with this error:
log file:
after some time of googling and thinking i've found that changing device back to default helps and xmms2 plays music. But the previous problem (too much CPU usage) is back :(

Can anybody help me in this situation. I don't know why xmms2 doesn't see device hw:0,0

output of aplay -l is:
I am on Ubuntu 8.10

I'm not sure how xmms differs from xmms2, but you can select the method of sound usage in xmms. OSS / ALSA / JACK / ARTS / ESD / PULSE AUDIO / ??? Accessing hw:0,0 only makes sense if you're using alsa in said configuration. You might also try simplifying it with just hw:0. And make sure you're not running other daemons that block usage. You might also be running into issues where a web browser (or plugin) is grabbing the OSS version of sound and locking the device from being used by other means / applications.

HTH

I'm using ALSA. And hw:0 does the same. I don't know why but xmms2 simply doesn't see this device. Do you know any daemons that may block usage or how to check it?
I think I'll read some documentation about how the sound system is working on Ubuntu. But if someone know how to fix this error I shall greatly appreciate any help :)
