Title:
Default to a2dp ldac_hq codec for bluethooth headset and sound
distorted
Status in pulseaudio package in Ubuntu:
Confirmed
Bug description:
I had some trouble getting my bluetooth headphones to work and I
believe the culprit is the default codec that pulseaudio chooses. It
appears to work ok when having no other Bluetooth devices connected,
but when connecting a bluetooth mouse the audio gets distorted and
begins to stutter. The offending codec is ldac_hq. I did some
investigating today and found out you can change the codec in
pavucontrol. Selecting ldac_sq seems to work without any issue.
I don't know what the problem with ldac_hq is, maybe bandwidth? Wasn't
able to find any obvious problems in the logs, even when enabling
debugging in bluez.
While investigating this I noticed others having the same issue, and
it was difficult to find a way to change the codec, so maybe ldac_hq
shouldn't be chosen as default?
