![]() You even get big PC releases like Halo 2: Anniversary that don't support surround sound at all. At least with this solution it is set and forget.Ĭonsoles do all of this so much better though it has to be said. Not ideal but the only other alternative I have is using a separate HDMI cable from the GPU direct to the receiver but this requires setting up a 2nd display device that I can't see, which is just too much ongoing hassle. I personally use patched realtek drivers to enable real time encoding to DTS over the optical connection on my motherboard. If you're using another TV this should work well but it's of no help if you're using an LG OLED.ĮARC is obviously the ideal solution but if you haven't upgraded both your TV and receiver in the last year then it's unlikely to be an option. I couldn't use it because LG OLEDs introduce audio lag from HDMI Dolby Digital sources which makes games unplayable. Yeah, this will real time encode games as well, so seems like a good solution for the op. I eventually probably will replace the Sonos Beam with a Sonos Arc, at which point I can drop DD 5.1 and use LPCM or Atmos for surround over HDMI, but until then this method is completely fine and cost nothing. SOLVED - the method posted by Dusker worked great, I now have proper DD 5.1 from my Nvidia GPU HDMI out to my Sonos Beam with minimal fuss involved, many thanks! Thanks also to everyone else who put forward suggestions, everything was useful in helping to clarify the issue and the options available. Mine does not, it only supports DD 5.1, hence why this is an issue for me and others. I would need to replace it with a Sonos Arc (£799) or equivalent for Atmos support.ĮDIT 2 - found this blog post on the topic which seems quite helpful: ĮDIT 3 - to replies along the lines of "no idea what OP is talking about mine works fine etc." This is probably because your receiver/soundbar/system supports LPCM (which most PC games output) for surround sound. If anyone has any insight into this issue, or even a simple solution I’m all ears.ĮDIT - to replies suggesting using Dolby Atmos, thanks for the idea but this is unfortunately not an option for me as the Sonos Beam only supports DD 5.1 for surround sound, not Atmos. ![]() Dolby Digital 5.1 works beautifully for all my other connected devices mentioned above but not for my PC, which only outputs Stereo PCM via the Nvidia card. Essentially it means PC gamers with the most powerful graphics hardware on the planet are gimped into using Stereo PCM audio when playing games.įYI my audio plays through a Sonos Beam (with 2 Play:1 rear speakers for surround sound). Why does a top of the range GPU that has a HDMI out connection not offer this basic functionality in this day and age? It’s insane. they all encode and output Dolby Digital 5.1 as standard. I don’t need to do this on my PS4, my Apple TV, my SkyQ box, or any other device I can think of in recent memory. ![]() or jump through crazy hoops and guides that may or may not work properly to download modded Nvidia drivers and lots of other bespoke software configuration just to output DD 5.1 over HDMI. So having invested in a brand new Nvidia 3090 card recently (although tbh it was the same for the 2xxx and 1xxx series cards before that) we still cannot output one of the most common encoded audio formats in existence via HDMI: Dolby Digital 5.1Īs far as I can tell the only options for comfy couch PC users wanting DD 5.1 surround sound are to either buy a separate sound card (but seriously, who even does that in this age) and use optical out.
