I think my unit is BROKE. I can ONLY get sound out of the DVD source with multi-direct 8. All other sources in both analog and digital do not output anything. Even variable direct 8 does not work. All other analog outputs from VCR, TV, tape and even my digital output from DVD player do not play ANY sound. Even the auto-calibration does not play any sound?? I have tried to reset the unit and still nothing. Only the multi direct 8 outputs sound. Any ideas?
