[Emilian Nowak]

Package: pulseaudio-utils
Version: 13.0-5
Severity: normal

Dear Maintainer,

I'm trying to use headphones with microphone (JBL Quantum800).
I can use them to listen to music with (a2dp_sink profile), but I cannot
switch to headset_head_unit. Hard to get from error message what is wrong - it
says: „Failure: Input/Output error”
