             Bug #: 29294
           Summary: No sound with ALSA loopback devices
           Product: Wine
           Version: 1.3.34
          Platform: x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: mmdevapi
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: amlopezalonso at gmail.com
    Classification: Unclassified


I recently set up an ALSA-to-JACK bridge (as described in
http://alsa.opensrc.org/Jack_and_Loopback_device_as_Alsa-to-Jack_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

Disabling JACK server plus unloading snd-aloop module restores the sound from
Wine.

I'll send more-specific logs upon request.

Regards,
Antonio
