--- Comment #4 from Loacoon loacoon@hotmail.com 2010-02-27 05:34:07 --- Sorry I forgot to add that launching Wine triggers the corruption.
I'm using Gentoo, kernel compiled by myself, I'm not using the kernel's version of ALSA but the Portage's one.
What is supposed to happen if the old API compatibility isn't activated? 'Cause the sound works with Wine, it's just corrupted/cracky (and corrupts it for any other app). I then have to mute/unmute the master channel to have a normal sound again.
Also note that Wine corrupts the sound when it starts, but if I mute/unmute the master channel without closing Wine, even the sound from Wine's apps works well.
