[Pkg-games-ubuntu] [Bug 503780] [NEW] OpenAL Soft doesn't work with PulseAudio (Ubuntu's default sound system)

[bojo42]

Public bug reported:

OpenAL Soft (the default OpenAL implementation) causes troubles in
combination with PulseAudio that is used by default on the Ubuntu
desktop. These troubles can be very different going from just no sound
to crashes and freezes of apps that use OpenAL (mostly games).

The root cause for this seems to be that OpenAL Soft has still no native
pulse output and the development of one has been stalled (
http://www.pulseaudio.org/wiki/PerfectSetup#OpenALApplications ). So
instead of using Pulse directly it uses ALSA as it's output and because
ALSA also has a pulse plugin the sound is routed to PulseAudio and then
back to ALSA. But this seems to be buggy, in Ubuntu at least ;).

I did this new report to synergize all the efforts of the various
reports about this issue, so there is already plenty of information on
the different troubles and on suggested solutions in the duplicates.
That's why we should try to stay focused here.
