Former custom ROM developer here who has reviewed and integrated valdikSS modification.
It’s not a bug that the patchset is doing, but enables dual-channel SBC to be negotiated in the source and sink connection. This enables the higher bit-rate without exceeding the maximum bitpool both Android and BT receiver impose.
There’s still negotiation occurs between the source and sink and if either one of them doesn’t support dual-channel SBc, it’ll fallback to whatever its supported. All the device that i had maintained supports it, while some cheap speaker that i test at that time doesn’t and able to negotiate joint stereo session.
