AVR HDMI out functionality - strange behavior

I had posted this under Yamaha AVR thread, but I think this has more to do with how any AVR is handling their HDMI connections so I am posting a separate thread for it.

This is how my setup is connected

BDP - AVR - TV (all connection via HDMI)
Tatasky - TV (HDMI)
Tatasky - Optical - AVR

Yesterday, I was listening to music on the BDP. For selection of songs I had the TV on and everything was hunky dory. After my song selection, I tried to switch the HDMI input on the TV to watch Tatasky (the TV has two HDMI In - AVR and TataSky). Strangely the music stopped as soon as I switched the HDMI. If I switch back to the AVR HDMI In on the TV, it works fine. It even works if I switch the TV off, but it was not working when I was switching the HDMI In on my TV.

The AVR's HDMI input was not changed and I have kept HDMI CEC off on all my devices. I am not sure whether it's supposed to behave this way

Hi,

This is indeed a strange behaviour. I know for a fact once you switch sources between HDMI, there is no music for 2/3 seconds but it resumes...I don't know why this happens but it seems to be more of an interruption that happens when pure digital signal (audio+video) is flowing and there is a sudden stop due to source changing.

Would suggest you try this....interchange the inputs to the TV sources and check if the same issue is happening. Also a little dust in HDMI ports can make the performance erratic ...you need to gently blow the dust off the cable ends and the ports on the TV / AVR.

The most important, check HDMI control settings (ON/OFF).

Hope this helps
 
My TV does not support ARC and it's disabled in the AVR. But would ARC have made any difference when I am not changing the input on the AVR in the entire process? So if ARC was enabled, it would not have switched to that input unless I explicitly select it on my AVR, isn't it?

If anyone has a similar setup (i am sure quite a few TSky users would have this kind of a setup between their BDP/TV/AVR/TSky. Can you guys please check and let me know? Even if you don't have TSky, can you guys just switch the input HDMI on your TV while playing any music on your BDP. Keep the AVR on the same input throughout.

I tested this again this weekend and same results. Basically when I switch the HDMI input on the TV, the AVR display keeps switching between 'Decoder Off' and 'PCM' intermittently, as if it's not able to hold on to the PCM signal coming out of the BDP.

When I switch off the TV too, the same flicker happens, but it eventually latches on to the PCM signal. Strangely, the HDMI that I have used between the TV and the AVR is the Amazonbasics 1.4 HDMI cord which is better than the other 'regular' monoprice HDMI that I have used elsewhere.
