With HCI_QUIRK_BROKEN_ENHANCED_SETUP_SYNC_CONN still applied ("HCI Enhanced Setup Synchronous Connection command is advertised, but not supported" is logged), recording from the headset mic gave real signal in both profiles: headset-head-unit-cvsd max -16.5 dB headset-head-unit max -18.3 dB (mSBC) The call failures I see now are tracked separately in bug 222151 (BT firmwa= re 20260813113236 regression).
