No sound in Wine with ALSA loopback devices

amlopezalonso · Post by **amlopezalonso** » Fri Dec 09, 2011 9:25 am

Hi,

I recently set up an ALSA-to-JACK bridge (as described in http://alsa.opensrc.org/Jack_and_Loopba ... ack_bridge) in order to route non-JACK apps into JACK. Every sounding non-JACK app (even Flash Player) work flawlessly but Wine outputs no sound (in theory, ALSA loopback devices should behave transparently to Wine).

I'm using git version and every audio app I ran in Wine (even the sound tests in winecfg) shoots several:

fixme:alsa:AudioClient_GetMixFormat Don't know what to do with 10000 channels

Any idea to troubleshoot this?

Thanks in advance

Wine only supports two channels of sound, only and it looks like your
program is querying the operating system to find out how many channels
of sound are supported.

I am getting this 1000 channels messages e.g. when clicking on the Audio
tab in winecfg. Don't know in which wine version this appeared, but
sound is working nevertheless.

You should open bug report. Wine's sound is broken ATM and it seems ppl who did it have no clue how to fix it. Filing bug at least documents the problem and hopefully make them aware the extent of things they've broke.

Thanks for your replies. It is definitely loopback related as removing snd-aloop module restores sound. I'll file a bug now.
