My 650 Ti has two DVI-Dual Link ports (or just one and a regular DVI it's kinda hard to tell, I use the Dual Link one.) And a Mini HDMI port as it's one source of audio. I don't have a Mini HDMI to HDMI cable to test out whether that works, however I've been reading most people have sound issues with HDMI anyways so I'm going to assume that's the case. I use my mobo's onboard audio out ports on the back and switching from Auto to Analog ALC388 which is the Realtek driver for that port I guess doesn't do anything. I can't get any audio out of either the rear audio IO or the front headphone jack. I have this gut feeling it's tied to how EmulationStation keeps resetting System Volume to 0 on startup every time I restart or shut down. And like I said in my original post, I've changed some Alsa settings and they reset too. Most people say to change recalbox.conf but my EmulationStation Sound Settings seem to completely ignore that as audio.volume could be set to 100, I can reboot, and the ES System Volume will be 0 again with recalbox.conf still showing audio.volume=100. I bought a cheap usb sound card this morning that will get here sometime this week. I'm guessing it won't solve my audio issues but I figured it would be worth a shot. All my USB devices work so I'm crossing my fingers that having a USB to stereo out will somehow redirect all audio from either the GPU or wherever it's focused from at the moment and I can get sound to my speakers again. But it probably won't solve the sound settings reset to 0 bug I'm dealing with.
