Today I picked up a third Monitor, an RCA 28" RLDEDV2813-A to be exact, which I am using a DVI to HDMI converter to connect it to my R9-290 Graphics Card. Previously I was using just an Acer monitor (DVI to DVI) and a Sony Smart TV (HDMI to HDMI). Before hooking up this monitor I had all my sound coming through my Sony TV, it was working fine. When I hooked up my new monitor/TV I couldn't get any sound. I went into Playback Devices and set my Sony TV as my Default Device and Default Communication Device. What else could be the problem? Thanks for the help in Advance! I am also using Realtek HD Audio Manager, if that has anything to do with it.
