My Denon AVR-4500h now suddenly has no Test Tone (part of the Setup menu) on any of the nine speakers or two subs. It used to work fine. I have done a hard reset, and still no Test Tone. I have taken it to Denon Service Center and paid to have it repaired...they said Test Tone was working fine. I use Test Tone to make individual speaker adjustments to my liking after an Audyssey calibration, for example, to bump up the center speaker. I used to do this all the time with Test Tone (A hiss, actually). Otherwise, everything seems to work, the AVR decodes ATMOS and provides audio on all speakers and subs but no Test Tone when using the Setup menu.
Have you ever heard of this issue?
