got up this afternoon after working nights powered up my 921 and turn on the tv and found that the sound was surging in volume. changed channels same problem. rebooted and hard reboot still voulme still going up and down without me touching the remote. allcsr would say is they will send me a new 921 in 5 days. does anybody have a better fix? oh yea I check to see if it was my jvc tv by playing a dvd which isn't connected to my 921 but straight to the tv. great sound there but when but when I switch inputs on the tv back to 921 sound still surging.
