Denon Firmware Issues?

Anyone here have a Denon S-model receiver? Those would include the 710W and the 730H.

My trusty 710W is (of course) now out of warranty and received a firmware update last week. Upon receiving it, my Xbox One immediately started having sound issues. Bitstreaming audio would randomly crap out when changing channels, swapping from TV to gaming, or swapping over to Netflix. When used with my PC and other HDMI inputs it would work flawlessly one minute and then the audio would die and not return between uses. Muting the audio and unmuting it worked at first. Then I had to power it off and on. Then audio just straight up stopped working on Saturday. I called support and they pretty much told me it was toast and in need of a repair...which takes an average of 2-3 weeks and isn't cheap.

So I decided to go and grab a newer 730H instead. It's essentially just a newer model. Out of the box it's great...but it ALSO got a new firmware that's a totally different number. Similar issues after the update, but not as extreme. Weird hiccups with bistreaming and swapping between content. Luckily it's only bitstreaming and only on the Xbox One.

Anyway, anyone else have this issue? If not, I'd also suggest not updating your firmware either automatically or manually.

I just picked up an S730H yesterday, actually... haven't hooked it up yet, but I'll check it out this evening.

I'm going to try the AVS Forums. Those threads that go on for like 500 pages make finding relevant information a total pain. None of my other devices got any recent updates and both receivers had Xbox bitstreaming issues immediately following that firmware update from last week.

Had I not gotten it on my 710W, I'd probably be able to keep using that AVR indefinitely. I'm paranoid that it was a way of weeding out older non-premium models. I paid like $300 for it and it does 99% the same things as the $450+ 730H.

As an update, I haven't noticed any issues yet. I updated the firmware to be sure we were on the same playing field (hey, I could always do a return / exchange...). I have a PS4 instead of the X Box, but that shouldn't make any difference.

The PS4 outputs as PCM or Dolby Digital/DTS. Atmos is the problem child unfortunately. I guess it might creep up on the PS4 if you set Netflix to bitstream, though. I think you can do that? Some Netflix content (like "Dark") uses Atmos rather than Dolby Digital +.
Per the AVS forums, it's apparently a known issue for lots of receivers. Previous versions of the firmware likely had a different implementation of Atmos and the update made Denon models vulnerable, too.

I'll see if that's an option when I get home tonight, but otherwise... yeah, makes sense I wouldn't have seen an issue then. Hopefully they fix it!
