Yamaha RX-V375 surround signals showing as PCM Hi Guys, I have had the same setup for over 3 years and I just noticed that my surround signals aren't being displayed properly on my Yamaha RX-V375 receiver. I have a home theater PC connected via HDMI directly into the receiver. For some reason, any video I play on the HTPC comes up as "PCM" on both the signal input menu and the front panel. I have a bunch of Dolby and DTS demo videos that I have used for years and the strange thing is, I am still getting 5.1 surround sound! Everything sounds normal... I tried reinstalling my laptop drivers to no avail. Since I do have surround still, this is just a minor issue but I do miss seeing "Dolby" on my receiver and am generally wondering what is going on. Anyone ever see a similar issue?
