[PATCH 0/9] Audio fixes and improvements

Posted by Volker Rümelin 3 years, 7 months ago

A few fixes and improvements from my audio patch queue.

It's currently still not possible to reach the function
audio_generic_read(). I tested the patch
 
audio: align audio_generic_read with audio_pcm_hw_run_in

with a modified audio/paaudio.c version. If someone wants
to reproduce the test, replace .read = qpa_read with
.read = audio_generic_read in the audio/paaudio.c pcm_ops
table and start qemu with
-audiodev pa,id=audio0,in.mixing-engine=off.

With best regards,
Volker

Volker Rümelin (9):
  audio: handle buf == NULL in put_buffer_out()
  audio/audio: fix video playback slowdown with spiceaudio
  audio/spiceaudio: always rate limit playback stream
  audio: align audio_generic_read with audio_pcm_hw_run_in
  audio: remove unnecessary calls to put_buffer_in
  audio: align audio_generic_write with audio_pcm_hw_run_out
  audio: run downstream playback queue unconditionally
  audio: restore mixing-engine playback buffer size
  audio: revert tests for pcm_ops table
