Microphone Gain Level

[Anonymous]

Does anybody know how to control audio input (mirophone) volume level on XDA and how to enable/disable AGC?

Below is my function for disabling the Microphone AGC

HRESULT DisableMicrophoneAGC()
{
LRESULT lr = 0;
HKEY hKey;
DWORD dwresult = 0;
DWORD dwdatasize =0;

lr = RegCreateKeyEx(HKEY_LOCAL_MACHINE,L"System\\CurrentControlSet\\AdvancedCPL",0,NULL,REG_OPTION_NON_VOLATILE,KEY_WRITE | KEY_READ, NULL, &hKey, &dwresult);


if(lr == ERROR_SUCCESS)
{
dwdatasize = 1;
BYTE bdata[] = {0};
lr = RegSetValueEx(hKey,L"MicrophoneAGC",0,REG_DWORD,(LPBYTE)&bdata,dwdatasize);
}


if(lr == ERROR_SUCCESS)
{
::RegCloseKey(hKey);
}


return S_OK;
}
