How to Change the MIC Gain on the MC50?
Facts
Changes to the audio gain parameter using the API (AUDIOEX_SetGain) do not take effect. The Audio API was incorrectly trying to set AuxLineInGain instead of bMicGain. In the MC50, the AuxLineInGain parameter is notsupported. The only supported parameters are bMicGain and fMic20dbBoost. The range of bMicGain is from 0-15.
Answer
AudExAPI.dll has been modified.
- Copy AudExAPI.dll, ResCoord.dll, wavedev.dll, MC50Audio_Updated.reg to the Platform folder (\Platform) of the MC50.
- Cold boot the MC50.
- Execute the custom application that adjusts the bMicGain.
