Hi Myria,

thanks, indeed I hadn't seen it. Sasha's approach is the better one
IMO, it only raises the links that carry audio. The dropouts I measured
are on the BCM4364 of the MacBookPro15,1 and 16,x behind hci_bcm, which
only needs hci_set_brcm_capable() on Apple machines on top of Sasha's
patch.

Luiz, let me tinker. I'll drop 1/2 and send the hci_bcm part on top of
Sasha's patch once I've tested. Then we should have it nice and
consistent.

Andre
