ok i'm one of the thousand? users, who have the big problem with skype and usb sound.
i've searched the whole internet for a good answer how to use a second soundcard (usb) with skype.
now i've found a site, someone (must be a guy from novell) say's there, in the two driver files for usb-audio is a bug and he has attached two newer files to his posting.
so i've downloaded this files, copied it over the two local files and restart my maschine.
and what for an wonder, after that i was able to switch to dsp1 and skype used it and my testcall to echo123 was succesfull.
i was able to hear the guy (the german answermaschine is a guy) and i was able to record my voice to him and hear my voice after that.
i've tested it 10 times, no problems.
one time i had the problem, after disconnecting the call in the first 3 seconds, the sound was gone, i must restart skype, then it was ok again.
the guy in this side say there is an updated kernel for suse 10.0 (kernel-version 2.6.13-15-default) with this new files, so try to find it and test it, but i think, it is easier for all, to use the two files, that you can download at the following link's:
www.people.freenet.de/go-mcpop/snd-usb-audio.ko
www.people.freenet.de/go-mcpop/snd-usb-lib.ko
copy this two files to "/lib/modules/2.6.13-15-default/kernel/sound/usb/" and overwrite the old two files.
i don't know if there the reason to restart the complete maschine or if you only need to log in again to the x-server.
i've tested all the point's in the pinned sound-faq's, but no tip was solving the problem.
so i've changed all back to the defaults before i start the testing and tried the two files.
try this out and will it solve the problem from all the other people here, then a mod should pin this topic or merge it with the existing sound-faq's.
