bluetooth: Add FastStream codec (!628) · Merge requests · PulseAudio / pulseaudio

Igor Kovalenko requested to merge igor.v.kovalenko/pulseaudio:pr/bluetooth-faststream into master Sep 08, 2021

This change adds A2DP FastStream codec with 16kHz voice backchannel. Spec hint https://lists.freedesktop.org/archives/pulseaudio-discuss/2019-June/031175.html

Originally tested with Avantree headset and found that backchannel stream has wrong SBC format (joint stereo not mono and 44.1kHz instead of 16kHz), but turned out this is a variant of norm at least for this device make pipewire/pipewire#974 (comment 1037294)

Closes #1175 (closed)
