But as far as i know it currently supports just that + tensorflow (which nobody uses it anymore, least here). And last we tried, so much of our kernels needs rework that it’s not worth the effort.

This may change since ironwood but we haven’t tried that generation.

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.
