[FIXED / WORKAROUNDED?] no audio (system-wide pulseaudio)

Hi,

For some unknown reasons, when trying to play ONI with a system-wide pulseaudio, it fails to initialize the sound.

The console doesn't give a lot of useful information.

When switching back to the standard user pulseaudio, the sound is OK.

I suspect there is either some mismatch between my system and the embedded fmod or a messy update either on my side or on unity's side. The sound worked fine in the past but i can't remember when nor when it got broken.

ONI is not the only game affected, Armello is affected too (also using fmod & unity, through steam), and so seems to be don't starve together.

User Feedback


I may have finally worked something out (fix or workaround, not really sure as i'm not an ALSA / pulse expert).

I added an alsa configuration file ( system-wide /etc/asound.conf or user ~/.asoundrc ) with the following content :

pcm.pulse {
type pulse
}
ctl.pulse {
type pulse
}
pcm.default pulse
ctl.default pulse

Maybe there is something crazy about unity/fmod trying to get direct access to the alsa devices, which would conflict with pulseaudio, if pulse already got its hand on the device (that is, some sound was actually played)

My devices don't have a hardware mixer, so only one client at a time is supported. That could explain the issue.

Anyway, for now, sound seems OK on all previously broken games (ONI, armello, maybe others)
