Commit 39f7f83 changed ao_driver.reset to use AudioUnitReset instead of
AudioOutputUnitStop. The problem with calling AudioOutputUnitStop was
that AudioOutputUnitStart takes a significant amount of time after a
stop when a wireless audio device is being used. This resulted in
lagging that was noticeable to users during seeking and short
pause/resume cycles. Switching to AudioUnitReset eliminated this
lagging.
However with the switch to AudioUnitReset the macOS daemon coreaudiod
continued to consume CPU time and did not release a powerd assertion
that it created on behalf of mpv, preventing macOS from sleeping.
This commit will change ao_coreaudio.reset to call AudioOutputUnitStop
after a delay if playback has not resumed. This preserves the faster
restart of playback for seeking and short pause/resume cycles and avoids
preventing sleep and needless CPU consumption.
Fixes #11617
