--- Comment #1 from Andrew Eikum aeikum@codeweavers.com 2011-08-10 07:53:25 CDT --- Sorry Jörg, I'm going to tell you to update :) Your alsa-plugins is too old. We require the handle_underrun setting to be supported to work around a PulseAudio bug[1]. Without the handle_underrun setting, your audio will drop out within about 15 minutes of playback. So your choices are:
1) Don't upgrade, remove the handle_underrun hack, and live with your audio dropping out after a few minutes; 2) Don't upgrade, leave the handle_underrun hack, and have no audio; or 3) Upgrade
I suppose there is a fourth option, which is to fiddle with the ALSA driver until the original drop-out bug stops happening. But I have spent weeks trying to make that work, and this was finally my best solution.
