Using Premiere unit at hotel and unable to adjust volume from being incredibly loud
I'm using Premier 3920 unit at hotel and am unable to adjust volume up or down. It's somehow locked onto 100 which is so loud the next town can likely hear it. I've changed HDMI cable, adjusted the actual TV volume settings, HDMI settings, and the Roku unit volume settings. Nothing makes any difference. Everything works fine like usual but will only play at an extremely loud volume. Only way I can hear audio w/out waking up the dead is to run Roku app from my phone as the remote and use my earbuds- uncomfortable. Yes, I have Roku remote w/me. Yes, I've used this and another Roku unit in hotels and never had any trouble until now. Any help is appreciated! Thanks.
