HF/HS hardware attenuation is optional on HFP: the peer indicates support with the AT+BRSF command, when bit 4 is set. That does not explicitly mandate speaker or microphone gain control; either is dynamically detected as soon as `AT+VG[MS]=` is received. Otherwise software attenuation is performed. It is also optional on HSP but nothing is mentioned about feature detection, assume it is the same as HFP: perform software attenuation until the HF/HS peer sends an `AT+VG[MS]=` command. When PA is a HS/HF (and the peer the AG) we attenuate both channels in software and unconditionally keep the peer up to date with `AT+VGM/AT+VGS` commands.
