When headphone mic boost is above zero, some 10 - 20 second delay might occur before the headphone mic is operational. Therefore disable the headphone mic boost control (recording gain is sufficient even without it).
(Note: this patch is not about the headset mic, it's about the less common mic-in only mode.)
