    Thanks.

    The problem is that yes i have multiple input devices without optical /coax out, and instead of tv Panasonic pt4000 projector.

    Maybe i can use some hdmi hub that can handle hdmi inputs, out. And somehow split audio via optical cable from hdmi input devices so i can redir it to avr?

    Not sure if optical can handle multi channel sound ie 5.1.

    Thanks.

    I think if you are doing a projector, the best bet is a new(er) receiver. The amount you'll need to spend for HDMI splitters and switches will exceed a typical used receiver price. Just do your research and avoid the ones that have HDMI problems. I grabbed an Integra DTR-50.5 several years back for under $200. It was flawless until I upgraded to a 4K setup.

    Cheap on used market, doesn't mean they were low quality. Receivers from previous generations don't hold much of their original value, especially if they can't pass 4K signals.

    I'm not familiar with either of those models. My advice usually is to check AVSForum under the Receivers section. There is usually a dedicated thread for each major model/series of receivers over the last 20 years. I know there was a stretch of Pioneer receivers with a bad batch of chips from TI. ALL of the early HDMI 1.3 models tended to have short lives on the HDMI boards. Onkyo seemed to get past that by around 2013 model year. I've had issues with each major brand in one way or another, so I don't think any one brand is better, it is highly model dependent.
    I would also recommend trying to shop local FB Marketplace and demand a demo of the unit to make sure there are no issues with HDMI, or otherwise.

    Yes. HDMI is the weak link in any receiver. Why? Probably because it was a rushed standard that has had several iterations and each time, they need to re-invent the chips, etc.

    I've had 3 receivers with HDMI issues out of 5 that I've owned. The only two I haven't are my previous Integra 50.5 and my current Pioneer SC71. Yes, even my current Sony ZA5000ES has one bad HDMI input. So far, it hasn't progressed to other inputs, but I've got my warranty card ready to call into Sony.
    The SR6008 is early 4K, aka not true 4K. If it doesn't have HDCP2.2, it won't pass any copy protected 4K material, which is essentially any 4K broadcast, streaming, or 4K Bluray. It will basically only pass something you created with video camera. My Pioneer SC71 is the same way. I live with it. Those receivers typically don't have Dolby Atmos or DTS-X processing either. That is a reason they go cheap.
