My sound has been acting up for a few weeks now on my Pioneer sc-97 receiver with arc hdmi I out. to my Samsung tv. Which has been working perfect for the last 4 years. Now when I turn the tv on for the first time in the morning everything works fine external speaker, video ,etc .And for as long as it is on. Once I turn everything off and turn in on again could be one ,2,3,4,5,6,7 hours later no sound from the receiver. Just get video on the tv. Then next morning when I turn it on it works again. Till I turn it off again same thing happens. Seems if it is left off for 12 or more hours the sound and everything works fine the first time it is turn on. Then again soon as I turn it off and back on again I get video but no sound. Its almost like a memory dump happens after a long period of time passes when the the receiver is off. Or might be an on going progression that eventually there will be no sound at all. Could it be a hardware problem. Like the arc hdmi 1 socket bad or software issue controlling the HDCP handshake in the receiver. Tried new cables , tv , all resets updates, settings are all correct. Seems something is failing.Or not communicating. Any advice.Thanks.

Sounds like something is getting warm. Only thing you can do is check connections inside. Probably best to take in for repair and it might be a bad chip / connection

Is it only the sound from the ARC connection that disappears, or do you have sound from any of the other inputs?

Yes I do have sound from other inputs. I thought it might be something getting hot .But would it take that long to cool down 10 plus hours.

If it is only sound from the TV to the AVR via ARC that disappears, it could just be a flaky ARC connection, which are common, unfortunately.

It may not help, but swapping the HDMI cable between the ARC connection on the AVR and the ARC connection on the TV to a premium certified one, will rule out a cable issue.

Failing that, does your TV have an optical audio output?

tried new cables yes it does have optical output
New cables may not necessarily be better cables. So, to be absolutely sure for not much money try a premium certified one, eg,

Amazon product
But, if an optical connection is an option, try that instead, and see if that works reliably.

just ordered 2 optical cables. I think hdmi is a bad design in regards to how it fits into the socket. Over time they seem to get lose. Thanks

well no sound from any connection through the receiver now. I guess I have to take it into the shop.Last time I buy a pioneer elite amp have had 3 in the last 15 years and always something goes on them within 5 years. Any advice on a new receiver under 1500.00 that will last longer . Thinking of a denon avr3500 or avr3600 do I have to stick to 4k and 2.2 hdmi to go with samsung un65ks9000. Thanks

I have had to switch to another input like Games and then back to TV to get the sound to work. This is annoying. Happens every time. Does anyone have a settoing idea. In addition, How can I get OSD to work. I cannot find a menu setting.
