Did you have to replace in MpCodec_setGain both instances of
MIXERLINE_COMPONENTTYPE_SRC_MICROPHONE with
MIXERLINE_COMPONENTTYPE_DST_WAVEIN or only the first one? The first
instance is in:
mxl.cbStruct = sizeof(mxl);
mxl.dwComponentType = MIXERLINE_COMPONENTTYPE_SRC_MICROPHONE;
mmresult = mixerGetLineInfo((HMIXEROBJ)hmx, &mxl,
MIXER_GETLINEINFOF_COMPONENTTYPE);
If I change just this one to MIXERLINE_COMPONENTTYPE_DST_WAVEIN then it
still works, and changes mic gain.
Then there is 2nd instance in for loop where we iterate through connections:
for(DWORD j=0; j<cConnections; j++)
{
mxl.dwSource = j;
mixerGetLineInfo((HMIXEROBJ)hmx, &mxl,
MIXER_GETLINEINFOF_SOURCE);
if (MIXERLINE_COMPONENTTYPE_SRC_MICROPHONE ==
mxl.dwComponentType)
break;
}
If I change this instance to MIXERLINE_COMPONENTTYPE_DST_WAVEIN then it
will change volume on the wrong control.
