On my desktop, I use the multichannel outputs of my motherboard (MSI z170a gaming m5) to output 7.1 audio to my receiver, which in turn powers my 7.1 system. I also have it connected via optical cable. I noticed that my center channel audio (whether in games, or movies/tv shows) is muffled when using the multichannel output. This problem does not occur when using the digital output, but I prefer to use analog connections as games that support positional audio (basically everything) can’t do positional audio over the optical cable — only the multichannel surround. The center channel is the only channel I have this issue with, but it is significant. Especially when watching movies, there is a drastic change in clarity between dialogue coming from the center versus playing it in stereo mode and having it come from the R/L fronts.
To troubleshoot, I have tried:
- Using a different(identical model) speaker for the center, no luck
- Swapping cables from the PC to the receiver
- changing any and all Realtek audio manager settings I could find
I cant figure out why this is happening. I am on Windows 10 1903, and my receiver is the Onkyo HT-R340. Any help is much appreciated!
