Summary: SND:CODEC:SSM2602: Default 40 dB gain overdrives the MICIN circuit

Details:

 

Don't enable 40dB Mic Boost by default.

There is no SND Control to turn off MICBOOST2 (20dB) afterwards.

40 dB gain overdrives the MICIN circuit on the BF526-EZBRD. The BF527-EZKIT is not affected since the BF527C internal audio codec doesn't feature MICBOOST2.

 

Please add an dedicated SND Control for MICBOOST2 and turn it off by default.
