Bug ID: 56430 Summary: Pulseaudio combined output dies under current wine Product: Wine Version: 9.4 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs@winehq.org Reporter: hibbsncc1701@gmail.com Distribution: ---
Since at least wine-9.3 using combined output (I.e. "Simultaneously output audio to all devices" in pavucontrol) kills audio output for all applications (even native Linux apps such as VLC) when launching an app through wine.
The linux side sound mixer shows all audio still being handled by pulseaudio. I.e. the current levels are rising up and down in sync with the actual audio attempting to be played, on all applications (even the wine application that triggered the bug) and on the output devices. (Even the devices that have been silenced by the bug.) Sound Mixer also shows no applications nor output devices as muted.
The disabled audio (both linux apps and wine apps) can sometimes be heard through the main output device, (I.e on-board audio of the motherboard), but any other device is always silenced until wine exits.
The result is things like bluetooth / USB headphones being rendered completely useless for all applications system-wide by wine.
