White noise or no sound after seeking, when using PULSEAUDIO:default

Component: MythTV - Audio Output Version: head

Description

Consolidating reports from downstream users:

FE configured to use PULSEAUDIO:default

Recorded or Live TV will start out playing correct audio, but seeking ffw or rwd loses proper audio, getting either white noise static (raw digital data?) or no sound at all.

To restore proper audio, one of the following must be done:

  1. Select an alternative audio channel and coming back to the default one
  1. Repeated skipping again or hitting pause will sometimes, eventually, restore audio
  1. If all else fails, get out of play mode and starting play again

Confirming. Further, using ALSA:pulse doesn't seem to work any more in Lucid, so this is the only useful option for audio support.... and it doesn't work right.

This is most likely an issue with pulse default internal resampler which is buggy.

Change the default pulse sampling rate to 48kHz (from 44.1kHz) or change the resampling method.
