Bug Description
Binary package hint: libao-pulse
As part of my testing of Jaunty, I have discovered that OpenAL applications have broken sound. Sound playback is distorted and scratchy. Other users with default Jaunty configurations are replicating the problem. So far, I have tried Warzone 2100 and Glest as applications using OpenAL. Another tester reported that he does not replicate the problem on the current GIT revision of pulse audio.
Doing a pkill pulseaudio; sleep 2; pulseaudio -vv it is seen that underruns occur and sound is rewound while OpenAL apps are trying to be run:

Yep, confirming for Jaunty Alpha2 and pulseaudio 0.9.13-2ubuntu3.
I get garbled sound and buffer underruns with
mplayer -ao openal /usr/lib/ openoffice/ share/gallery/ sounds/ space2. wav
It works fine though after killing pulseaudio (pulseaudio -k).
