Just got the whole home pvr and are having trouble with the volume control:
1) When we press play after fast forwarding, the sound goes to mute. No sound is heard unless you press volume up even though there was sound prior to fast forwarding, and
2) although the volume display bar at the bottom of the screen moves left to right when trying to increase the volume, the actual sound does not get louder. The TV volume control works properly but the 'cable' one does not.
Re: Motorola dcx3400 whole home pvr volume control
I have the same issue. The on-line manual suggests setting the cable box volume at 3/4 on scale and using the device volume control, in this case the TV. It is a nuisance as you have to press TV on the Shaw remote to control volume or the TV remote. I had the Pace expander until it failed and it integrated the volume control.
