I'm having the same issue ("choppy" audio during music playback in Banshee or any other media player) since Nov 17. Four gstreamer "bad" plugins were updated. See attached screenshot of history.

At first I thought it was something with my processor or BIOS because I had installed additional RAM the same day, but removing the RAM did not improve thing. Curiously, I experienced the same problem when playing a YouTube clip while running the LM18 live DVD.

That rules out the gstreamer-plugins-bad possibility....

Install pavucontrol:

Code: Select all

sudo apt-get install pavucontrol
Then launch it and experiment a bit with the settings. Reduce volume level to 90 - 95 % (instead of 100 %). Things like that.

Thanks, Pjotr. I played around with the volumes and settings in there but no luck. Audio is still choppy.

uname -r

Try if it helps when you boot from an older kernel.

Update: choppy audio issues returned unexpectedly a few days ago, despite no change in kernel. I can confirm that I'm having this issue with 4.4.0-45, 4.4.0-47, 4.4.0-51 (LM18 64bit). The oldest kernel installed on my system right now is 4.4.0-21, and it's slightly better than the latest ones but still frustratingly not good enough. I also tried the low latency version of 4.4.0-21. I didn't have any audio issues in LM 17.3 (32bit). Is there a way I can install kernel 3.19 in LM18? I don't see it listed in Synaptic. Could there be something else causing this?
