alsa: disable period wakeups in tsched mode if possible
This patch reflects a new capability that Lennart was wishing for. Wish granted... Re-submitting it now that alsa-lib 1.0.24 provides additional entry points to disable period wakeups in timer-scheduling mode if hardware can work without it (HDAudio, oxygen and Intel SST). Example with standard playback on HDAudio output Before change: Top causes for wakeups: 3.8% ( 5.4) [hda_intel] <interrupt> 2.8% ( 4.0) alsa-sink After change: Top causes for wakeups: 2.3% ( 3.0) alsa-sink Signed-off-by: Pierre-Louis Bossart <>
