I have a Proscan 32" TVf (32LB30QD). The TV has a coax output port. I purchased a digital converter. I am able to connect the headset. Audio comes through, but I am not able to adjust the volume.
Similarly, I connect the digital converter to the set top box (IPC1100P2). I am able to get sound, but not able to control the volume
I've gone into the set top box setting. I see where I can set audio to fixed or variable and set the sound level. Once I exit the set top box settings, I am not able to control the audio volume with the remote.
any suggestions on how to control the audio volume?
