I'm facing intermittent bluetooth connection issues where I can connect a device on startup and after a while (30mins) the connection will be degraded (skipping/jittery). If I then disconnect the device and attempt to reconnect it from blueman-manager I get the following two cases:

  1. A successful connection, after which the device is not listed as an ouptut in pavucontrol
  2. Connection error: Connection Failed: Resource temporarily unavailable

Solutions attempted

  1. Unpairing/repairing the device
  2. Resetting the pulseaudio config (https://askubuntu.com/a/875891/1569612)
  3. Restarting pavucontrol (pulseaudio -k) or restarting bluetooth (systemctl restart bluetooth.service)
  4. Attempting to reload pulseaudio-discovery module (https://askubuntu.com/a/1062044/1569612) Above yeilds the following error
taylorswift2018@box:~$ pactl load-module module-bluetooth-discover
Failure: Module initialization failed
  1. Load pulseaudio after x11 (https://askubuntu.com/a/689297/1569612)

The output of systemctl status bluetooth.service

After trying out a the open source driver from the gnome driver panel driver-panel and still seeing problems I decided to build and update the driver myself as I believe the apt version of this package is outdated. Installing this driver using the following remote and instructions and restarting gave back consistent bluetooth behavior

Edit: No it didn't and i've given up and decided not to use wireless as a workaround because i've burnt enough time on this garbage.
