[OS 12.5] No sound in Express+ after latest firmware update

After the latest firmware update (12.5.0, build 4178-51), the sound is completely gone once the device gets to the main screen. There *is* sound with the startup logo and other devices connected to the TV, so it doesn't seem to be a hardware thing, but after the loading screen it cycles through the HDMI port and DVI port and loads the main screen in a fuzzy resolution, and there is no sound in any of the apps. Perhaps the latest update should have gone through more QA testing?

    OK, so after a little further investigation, it looks like the HDMI connection between my streaming stick and the TV is being treated like a DVI connection After the Roku loading screen, the TV cycles through HDMI1, HDMI2 (where it used to stay), and then a purple band flashes and it says 'DVI 1920 x 1080' (probably why the display gets fuzzy). This is a TCL 48FS4610, which is old I guess, but it was working fine right up until Roku pushed this last update.

      After further troubleshooting, I have found that I can get my Roku Express+ streaming stick to work if I leave it unplugged while both the TV and the streaming stick power on, and then plug it in (wait like a full minute after you turn on the TV and the little LED on the Roku turns on). I am only guessing, but maybe the Roku is checking for HDMI before the TV makes it available, and then falls back into a DVI mode?

      NOTE: I only discovered this after testing with an older Roku stick I had laying around the house. It was several versions back from the firmware released today, but the audio and graphisc were fine until I updated to the most recent firmware updates. This leads me to believe that there's a bug in the recent firmware version.

        Man, you're a lifesaver.  Could not for the life of me figure out how to stop the Roku from switching over to DVI, and waiting a minute to plug in the HDMI cable did the trick.  Roku needs to patch this ASAP!
