[Bug 405294] Re: a2dp skips terribly

 

Affects me as well on Arch. Works flawless on Android.
Laptop: Thinkpad T430
Speaker: Sony SRS-X3

I feel it might be related to WiFi interference. How does Android handle
this?

Title:
  a2dp skips terribly

Status in PulseAudio:
  New
Status in bluez package in Ubuntu:
  Confirmed
Status in pulseaudio package in Ubuntu:
  Confirmed

Bug description:
  As I upgraded to the Karmic alpha, bluetooth audio (via a2dp) stopped
  working properly. It was working fine in Jaunty.

  My headphones are detected and configured by pulse, but the audio
  skips as if it's spending half of each second paused. Music is
  buffered so that after I click stop on rhythmbox (or whatever--it
  happens with whatever player I use) the audio continues until it's
  caught up.

  syslog is full of the following lines:
  Jul 27 08:55:45 carlin1 pulseaudio[3218]: alsa-source.c: Increasing minimal latency to 1.00 ms
  Jul 27 08:55:46 carlin1 pulseaudio[3218]: module-bluetooth-device.c: Skipping 15128 us (= 2668 bytes) in audio stream

  Jul 27 08:55:46 carlin1 pulseaudio[3218]: module-bluetooth-device.c: Skipping 32589 us (= 5748 bytes) in audio stream

  This is with
  bluez                             4.45-0ubuntu4
  pulseaudio                    1:0.9.15-4ubuntu2 0

  pulseaudio version 1:0.9.16~test2-0ubuntu1~ppa3 from ubuntu-audio-dev
  didn't help.
