mSBC does not work with chips such as BCM20702A - provide wiki of supported chipsets?
i was excited to try the latest pipewire-git with my Sony WH-1000XM3 and my ASUS BT-400 bluetooth adaptor. unfortunately the headphones do support mSBC but the adapter does not. see here:
perhaps a wiki could be provided of chipsets that support HFP 1.6 16Khz?
i believe that some Realtek ones do, for example.
