Hi Sam,

Another set of logs.

Same setup as detailed in post, above.

Stuttering begun less than a minute into playback from beginning of episode.

Https://paste.osmc.tv/aqevazecob

The stuttering is over too quickly to obtain any readings from Top or Dstat, unfortunately.

Oops…

Do you have A2DP installed?

Running sudo apt-get remove --purge pulseaudio might help…

I was able to replicate the issue at the exact same point, but wasn’t expecting to, so didnt have an ssh session up. Of course it wouldn’t replicate a third time.

Yes, i installed a2dp for bluetooth a few weeks back, but not using it and completely forgot about it… hope your debugging sense is on the money!

Purging now.

[Edit]
I’ve removed the pairing which existed to my Anker Soundcore 2, and disabled Bluetooth, both via My OSMC, and rebooted for good measure.

In case it’s of any use, the thread where I got bluetooth audio working (partly via command line) is here:

My memory is so bad now, I forgot not only all about the work involved in setting it up, but that I had A2DP
installed at all.

I’ll report back with findings…

Seems your debugging skills are razor sharp as always @sam_nazarko; so far I’ve seen no issues since removing A2DP, which has also resolved a few gremlins which must have been related:

  • slight pauses when pressing the (i) button during playback
  • a few seconds of audio only, followed by overcranked playback until the video synched
  • youtube playing with no audio for c. 20 seconds when skipping ahead, or resuming)

Many thanks for your excellent work; wishing you a great 2019.

Hi RR,

Good stuff. A2DP is still very rough around the edges; and I do apologise for not noticing this before in your logs.

It should also please you (and @dastrix) to know that the range limiting option you requested will also be in the next update which should land tomorrow thanks to some excellent work by @grahamh.

Have a good 2019 yourself; I hope you are on the mend.

Cheers

Sam
