pVal |
Pointer to a variable that receives the current left channel power level. |
Used to query the current left channel power level. The range is -10,000 to 0. Full power is 0, and -10,000 is silence; the scale is logarithmic.
Divide by 100 to get the equivalent decibel value (for example, -10,000 = -100 dB).
S_OK if successful, an HRESULT error code otherwise.
