Re: small improvements for fedora 3: sound mixing

[Christian Paratschek <christian paratschek reflex at>]

hi!

this does not work for me. xmms and rhythmbox play fine, but gaim sound
does not and gaim crashes when i try to close it.

i am not a programmer  but i test whatever you tell me :-)
would be great if i could be helpful here...

regards,
christian
