Pointer to an IltmmCapture interface.
Pointer to a variable to be updated with the balance value. Possible values range from -10000 to 10000, where -10000 indicates that the right channel is receiving no signal, 10000 indicates that the left channel is receiving no signal, and 0 indicates that both channels are getting the same amount of the audio signal.

| S_OK | The function was successful. |
| <> S_OK | An error occurred. Refer to the Error Codes or the HRESULT error codes in the DirectShow documentation. |
Units correspond to .01 decibels (multiplied by -1 when pVal is a positive value). For example, a value of 1000 indicates -10 dB on the right channel and -90 dB on the left channel.
