Thanks for the patch.
But the patch you embedded in the mail is broken due to MUA, and
can't be applied cleanly.

Please fix your MUA setup or use an attachment if it's difficult.


thanks,

May somebody indicate how to apply the patch?

I guess download current stable source code, then write patch changes in source
(which git command for that and how exactly? doesn't it affect multiple alsa
projects?) and then compile?


Thanks a lot.
