Wine output log at commit babaf916ab12c7a9128409f717878919ccc5826b
Starting with Wine 6.21, some in-game audio no longer works, including game
music, all NPC voices, and player's voice during attacks. Other sounds still
work normally, such as GUI sounds, weapon sounds, magic casting, footsteps and
doors opening and closing. It's as if the game only plays a single audio
channel. The bug is reproducible in any game area, for example by starting a
new game or loading an existing save.
I did a regression test, and it seems that the bug was actually introduced
earlier in Wine 6.20, with the following commit:
...
d8be85863fedf6982944d06ebd1ce5904cb3d4e1
xaudio: Use the bundled FAudio and build with msvcrt.
However, in that version the game crashes immediately after the intro sequence
with error:
...
Assertion failed: (voice->src.wmadec != NULL && (pBufferWMA != NULL || voice->src.format->wFormatTag == FAUDIO_FORMAT_XMAUDIO2)) || 
(voice->src.wmadec == NULL && (pBufferWMA == NULL && voice->src.format->wFormatTag != FAUDIO_FORMAT_XMAUDIO2)), file ../wine-git/lib
s/faudio/src/FAudio.c, line 2456
Then, this seems to have been fixed immediately in the next release 6.21, in
commit:
...
babaf916ab12c7a9128409f717878919ccc5826b
faudio: Build with -DNDEBUG.
After this the game works, but it behaves as described above. The attached log
was made using the second commit. The bug is still present in the current
latest 7.1 release.
I've CC'ed the authors of both commits like mentioned on the regression testing
wiki page, I'm uncertain which one should be considered more relevant for the
bug. My interpretation is that the newly introduced bundled version of the
faudio library is built or configured differently than the previous
distro-provided shared dependency, and disabling debug assertions just made the
message go away but there's still an issue, so I guess both are relevant.
