I just noticed that I can no longer play any sound in wine. It doesn't matter if I run a program through wine (in which case wine crashes) or just test sound output in winecfg, I always get the following errors:

Code:
$ winecfg
fixme:heap:HeapSetInformation (nil) 1 (nil) 0
fixme:process:SetProcessDEPPolicy (1): stub
fixme:heap:HeapSetInformation (nil) 1 (nil) 0
ALSA lib conf.c:3314:(snd_config_hooks_call) Cannot open shared library /usr/lib/alsa-lib/libasound_module_conf_pulse.so
ALSA lib pcm.c:2217:(snd_pcm_open_noupdate) Unknown PCM default
err:ole:CoInitializeEx Attempt to change threading model of this apartment from multi-threaded to apartment threaded


Code:
$ pasuspender winecfg
fixme:heap:HeapSetInformation (nil) 1 (nil) 0
fixme:process:SetProcessDEPPolicy (1): stub
fixme:heap:HeapSetInformation (nil) 1 (nil) 0
ALSA lib conf.c:3314:(snd_config_hooks_call) Cannot open shared library /usr/lib/alsa-lib/libasound_module_conf_pulse.so
ALSA lib pcm.c:2217:(snd_pcm_open_noupdate) Unknown PCM default
err:ole:CoInitializeEx Attempt to change threading model of this apartment from multi-threaded to apartment threaded


Choosing specific ALSA input/output devices in winecfg doesn't help. Other programs run fine directly with PulseAudio, using the PulseAudio ALSA module or using ALSA directly after pasuspender. I already tried recompiling wine (was 1.5.21, no change after upgrading to 1.5.23), alsa-plugins (1.0.25-r1) and pulseaudio (2.1-r1), ran lafilefixer and revdep-rebuild.

I previously used the following setup in /etc/asound.conf until I read the notice after recompiling alsa-utils that it's no longer necessary:

Code:
# make default device forward all audio to PulseAudio
# (use hw: prefixes to access real hardware and make sure this is also in PulseAudio config)
pcm.!default {
        type pulse
}

ctl.!default {
        type pulse
}

# add a pseudo-device for explicit forwarding to PulseAudio
pcm.pulse {
    type pulse
}

ctl.pulse {
    type pulse
}


I removed it, logged in again and rebooted since I wasn't sure the changes were really applied yet. No change.

If I run alsa-info it detects PulseAudio: (no other mention of "pulse")

Code:
Pulseaudio:
      Installed - Yes (/usr/bin/pulseaudio)
      Running - Yes


The inofficial winepulse.drv doesn't work for me, so I forced wine to use ALSA instead (which worked up until now, sometimes using the PulseAudio module, sometimes by temporarily disabling PA using pasuspender). I didn't run wine for a few weeks and did an intense world upgrade in the meantime (the previous full update was somewhere in May 2012), so I can't exactly tell what broke it. Judging from the Google results that turned up, the problem appeared across multiple binary distributions years ago, so it's likely I just need to recompile something.

Any idea what else I could try? I've currently run out of ideas.

I just ran strace on winecfg and that's when the error occurs:

Code:
open("/usr/lib/alsa-lib/libasound_module_conf_pulse.so", O_RDONLY|O_CLOEXEC) = 16
read(16, "\177ELF\2\1\1\0\0\0\0\0\0\0\0\0\3\0>\0\1\0\0\0\300\t\0\0\0\0\0\0"..., 512) = 512
close(16)                               = 0
write(2, "ALSA lib conf.c:3314:(snd_config"..., 45ALSA lib conf.c:3314:(snd_config_hooks_call) ) = 45
write(2, "Cannot open shared library /usr/"..., 75Cannot open shared library /usr/lib/alsa-lib/libasound_module_conf_pulse.so) = 75
write(2, "\n", 1
)                       = 1
write(2, "ALSA lib pcm.c:2217:(snd_pcm_ope"..., 44ALSA lib pcm.c:2217:(snd_pcm_open_noupdate) ) = 44
write(2, "Unknown PCM default", 19Unknown PCM default)     = 19
write(2, "\n", 1
)                       = 1

So it stops immediately after reading the ELF header?

Sounds strange to me and so I checked:

Code:

$ elfls /usr/lib/alsa-lib/libasound_module_conf_pulse.so
/usr/lib/alsa-lib/libasound_module_conf_pulse.so& (Intel x86-64)
[...]
$ elfls `which wine`
/usr/bin/wine* (Intel 386)
[...]


Looks like wine would either need a 32 bit libasound_module_conf_pulse.so or wine has to be compiled in 64 bit? (I'm on amd64; CPU is an Intel Core2Duo) Unfortunately, emul-linux-* is already at the latest available version:

Code:
[I] app-emulation/emul-linux-x86-soundlibs
     Available versions:  20121028^s 20121202^s {{alsa development}}
     Installed versions:  20121202^s(02:26:14 PM 01/15/2013)(alsa -development)
     Homepage:            http://dev.gentoo.org/~pacho/emul.html
     Description:         Provides precompiled 32bit libraries

Could that really be the source of my problem or is it a red herring?


Edit: I'm wondering if these USE flags should be mutually exclusive? I currently have both set:
Code:
 + + win32         : Build a 32bit version of Wine (won't run Win64 binaries)
 + + win64         : Build a 64bit version of Wine (won't run Win32 binaries)

'win32' and 'win64' aren't mutually exclusive - they're independent.
wine is simply screwed up that way by design.
