Description Vahur Sinijärv 2005-04-24 22:33:57 UTC

I had severe problems with surround sound with current alsa-lib (1.0.9_rc2-r1) in portage. Symptoms are looping buffer effect when you try to play through surround51 or surround40 or any plug based alsa device.
I found this fix and description of the problem from Alsa dev mailing list and seems they have fixed this in CVS.
Here are links to the bug description:

Attached is a patch what the guy used to fix the problem and indeed it works and fixes the issue and also applies cleanly to the alsa-lib in portage.
