See https://test.winehq.org/data/patterns.html#xactengine3_7:xact3
Where:
0x88960001 == XAUDIO2_E_INVALID_CALL or XAUDIO20_E_XMA_DECODER_ERROR
0x8ac70002 == MAKE_HRESULT(SEVERITY_ERROR, FACILITY_XACTENGINE,
XACTENGINE_E_NOTINITIALIZED)
These failures only happen on w11pro64_amd and w11pro64_nv. What these have in
common is that the sound is supposed to go through the graphics card's HDMI /
DisplayPort connection. However those go to a dummy plug which emulates a
screen... but not speakers. This causes Windows to disable the sound volume
widget since it cannot detect any form of speaker.
I suspect, but that may require confirmation, that this causes xact to refuse
to initialize.
More notes:
* My fgtb-w10pro64-rx550 VM has the same audio-through-HDMI configuration but
is connected to my real screen which does have speakers. So sound is not
'disabled'.
* QEmu emulates an ich9 sound card in the regular w11pro64 test configuration
and Spice (the virtual KVM) provides the remote speakers. So again sound is not
'disabled' (and I always lower the default volume in the VMs so I don't get
deafened by the Windows boot sound).
* Before 2022-12-09 the w11pro64 VM was missing many DirectX dlls which caused
this test to be entirely skipped. This is why it did not crash on these test
configurations before then.
