For the past 3 months my DVR/cable has started to lose volume. Volume controls are now hovering around 70 and no increase in volume is heard even if I go to a higher setting. Volume drop is for all channels and all recordings. Today I lost sound all together, thinking it was my TV, I installed it onto another Comcast cable box, sound was clear and loud.
I have checked my cable connectors, all good and secure. I have yet to unplug my cable box to see if it resets the sound somehow. Ideas?
