Hi! I would suggest to wait until my patches for extending A2DP codecs
is reviewed and merged. You can find them in email with subject
"[PATCH v10 00/11] Bluetooth A2DP codecs"

In this patch series is also big rework of SBC codec, to support e.g.
UHQ mode and your changes would introduce new conflicts with that patch

Anyway, correct behavior of SBC codec in automatic mode should
automatically increase or decrease SBC bitpool based on available
