Hi everybody,
I don’t know if there is a relation between this problem and my other sound trouble with banshee.
I install skype with following instruction of the opensuse wiki. It works good, video is nice and sound is good … when it works 
I’s using a Creative Live! Cam Optia AF with uvc webcam driver on Suse, it works great video and sound under cheese for exemple.
But when i’m on conversation with someone. Video is ok all the time, i heard him very weel but it seems my sound doesn’t work after a time and sometimes, it works again during few seconds or minutes before not working again… It’s quite anoying, I hope you couls help me lol!
Best regards
(my english is bad, i could try to explain more my problem if you want)
