Has anyone else suffered a problem with the AV32R auto mute feature getting stuck on? Mine does this after using my X-Box through it for prolonged periods of time. I have contacted the Tag helpdesk and they have confirmed that thee is an issue with the X-Box and the AV32R's SPDIF receiver chip due to out of tolerance SPDIF transmitters on the X box. They have told me to try switching between anologue and digital inputs to try and clear it or turn it off at the front panel. I have tried both of these with no great success. The really annoying thing is that it only seems to affect the DVD input by keeping this in a muted state where as all others including the X-Box (renamed MD i/p) are fine. Any ideas?
