Wideband (mSBC) support was added into Pulseaudio 15 btw: https://www.freedesktop.org/wiki/Software/PulseAudio/Notes/15.0/#supportforhfpbluetoothprofiles https://www.freedesktop.org/wiki/Software/PulseAudio/Notes/1... It also added support for using higher bitpools for the SBC codec (sbc, sbc_xq_453, sbc_xq_512, sbc_xq_552) which pushes its quality above APTx and the other proprietary codecs.
