[pulseaudio-discuss] Current status of wideband speech?

[diego.ml]

Hi Ta-Lun,

actually there's an updated patch for Wide Band mSBC codec support:
https://patchwork.freedesktop.org/patch/245272/
It should apply cleanly on master if you want to test it / improve it.

If you're working on 12.2, you'll also need to backport this commit (git cherry-pick will do):
https://github.com/pulseaudio/pulseaudio/commit/fb600395e1e13ef68e36153faf02bda287927ae2

Personally I've backported the patch to 12.2 and it worked fine so far with a Broadcom / Cypress chip (Sterling LWB5 module).

Bests,
Diego
