           Summary: handle_underrun=1 hack causes IMMDevice::Activate to
                    fail with PulseAudio
           Product: Wine
           Version: 1.3.26
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: winealsa.drv
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: hoehle at users.sourceforge.net


Given Andrew's past 1.3.25
commit 9ad60d1d143809c6ae477eb53e75c3dc93736e0e
Date:   Fri Aug 5 09:33:10 2011 -0500

    winealsa.drv: Inject handle_underrun=1 setting for pulse-backed devices.

IMMDevice_Activate now fails when pulse is the default device. As a result,
mmdevapi is unusable (=> no more sound) and unwary apps like
dlls/mmdevapi/tests/render.c:test_session crash.  dmix still works.

The console log is:
ALSA lib pcm_pulse.c:855:(_snd_pcm_pulse_open) Unknown field handle_underrun
warn:alsa:AUDDRV_GetAudioEndpoint Unable to open PCM "default": -22 (Invalid
argument)
render.c:141: Test failed: Activation failed with 80004005

I'm using Ubuntu Intrepid. Please don't tell me to update. That is not the
solution.

Probably the interim hack should check the effect and revert to standard
behaviour/configuration in case of an error.
