No matter how I try to program or how I try entering information, I have no volume or mute control using the new P2 - STB for external speakers. I am using amplified computer speakers connected to the rear of the STB at the appropriate jack location. I had no problem setting this up with the old box (sorry, can't remember model#). Any ideas or (hopefully) a solution would be much appreciated. Thanks!
Stb is probably set for fixed audio volume.
Go into settings under audio and change volume setting.
