#7243 closed defect (fixed)

Pulseaudio supsend doesn't work because ALSA:default can redirect back into pulseaudio

Reported by: superm1@… Owned by: danielk
Priority: minor Milestone: 0.22
Component: MythTV - Video Playback Version: head
Severity: medium Keywords:

There is an alsa-plugin for pulseaudio that redirects sounds from ALSA:default into ALSA:pulse when pulseaudio is running.

In order to prevent this from happening, an environment variable can be set to cause that plugin to abort when an application tries to use it.

(In [22295]) Fixes #7243. Be a little more agressive in disabling pulse audio. Needed for Ubuntu 9.10, appears harmless with to earlier revisions of the pulse audio scripts.

Actually, I have myth working fine through pulseaudio on 9.10... over HDMI, analogue stereo, and A2DP headsets. (Even simultaneously over HDMI and A2DP). I run with EXPERIMENTALLY_ALLOW_PULSE_AUDIO set, pulseaudio set to use real-time scheduling, and the following in .asoundrc:

pcm.!default {
  type pulse

ctl.!default {
    type pulse

Works great, including ffw/rwd where previously I often lost audio.
