Hi all, I apologise in advance if this topic has already been covered. I've tried a quick search on Google and on this site, and so far yielded no results. So, where to begin? I've recently installed a 7.2.4 (upgrade from a 7.2) set-up and watched one film in native Atmos using my Sony UBP-x800. I've since then attempted to configure my Windows 10 PC to allow Atmos. I've gone through the usual 'Sound' settings in Windows to choose the number of speakers. There are some advanced settings within Windows to choose spatial settings (Dolby Atmos etc.). Anyway, I'm not sure whether it worked or not? In any case, this isn't the relevant issue here (at least I don't think it is). The current options on my Denon AVR x6300H receiver of course provide both the Dolby and DTS upmixers for non-native Atmos or Nueral source materials; DSU and DTS Nueral:X. In an attempt try out both upmixers with sound content on my PC, I was shocked that Dolby's upmixer began causing intolerable distortion, which admittedly isn't present all the time, but definitely most of the time. And by that, I mean occasionally it works fine, but if for example I change to Nueral:X, and then switch back again to DSU, the distortion (mostly in the form of loud crackling) starts and continues relentlessly. It is so bad that it is both unlistenable and perhaps even damaging to the speakers? Nueral:X on the other hand works as it should do without a hitch, and makes even some old games sound awesome despite their age. So, it looks like I'm restricted to using Nueral:X, which I can live with since it does a fantastic job. Still, I'd have preferred to have had the option of using DSU all the same, and I am wondering if anyone else has come across the same or a similar problem with DSU, or perhaps, conversely Nueral:X? Also, the plot thickens ever so slightly. I noticed shortly afterwards when preparing to test out both upmixers on some films (using Blu-ray discs on a UHD player, not on my PC), that the DSU once again causes the exact same distortion issues - just as those it causes on my PC - on the film's main menu screens of those which have a DTS 2.0 encode. Once the films begin playing however, DSU appears to work fine even with a DTS encoded track, though it was a DTS HD-Master Audio 5.1 track. I haven't tested DSU with a film fully mixed in 2.0. Anyway, I find it more than a little odd and mystifying that I'm encountering such issues - albeit fairly minor though they seem to be - when nobody else appears to have done.
