Hi Ta-Lun,

actually there's an updated patch for Wide Band mSBC codec support:
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):

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