Description of Problem:
When connecting with my Bluetooth headset (Plantronics BackBeat PRO) my microphone now appears to have its audio skip repeatedly. First encountered while attempting audio chat on Discord when I was told I "sounded like a robot". Used Helvum to directly map the capture from my BT headset to the playback and verified it happens outside of Discord.
Happens whenever I have my BT headset on HSP/HFP profile and have audio captured from the microphone.
Steps to Reproduce:
- Connect BT headset to Bluetooth on computer
- Set audio profile to HSP/HFP (done via KDE System Settings > Audio > Configure)
- Listen to audio from BT headset
Audio from microphone skips repeatedly very quickly. Sounds "like a robot."
Clear audio with no skips.
Additional Info (as attachments):
Started with a Manjaro update yesterday which moved my Pipewire version from from 0.3.35 to 0.3.37. Worked well prior to this. Also tried moving my kernel from 5.13.19 to 5.14.7 but this did not resolve the issue. Unfortunately, I don't know how to go back to pulseaudio so I have not tested to see if the issue occurs in pulseaudio currently. I'm also assuming this is a Pipewire issue, but a variety of other packages were updated including the KDE frameworks.
This is my first bug report, so please let me know if I've missed something or can help further.
pw-dump -N > pw-dump.log
When monitoring with pw-top, there appears to be periods of extended wait times (sometimes the number in the "WAIT" column gets huge and looks like some kind of overflow or negative number as captured below). The "ERR" column also repeatedly goes up while talking through the microphone.
