Roku Ultra Audio Issues when using all apps

I'm having audio issues with my Roku Ultra. Volume fluctuation, Chirps, distorted sound. I did everything roku support staff suggested - reset, power cycle, hard reset on the device, check software updates, changes HDMI cables.... still the issue remains. Support person asked me to go buy another roku device since the warranty is over. It seems like lot of other people are having similar issue. Why would they ask to buy a new device if they cant fix the issues with their devices. If anyone figured out a way to fix this issue please suggest. This happens only using app through roku device. Thank you

    You didn't mention which Ultra model you have (there are many:  4640, 4660, 4661, 4662, 4670, 4800, 4801, 4802, 4850):  Settings/System/About

    There are differences in optimal settings as well depending on whether the model has a Dolby decoder.

    For a 4640, 4800, 4802, and 4850 you need to change: Settings/Audio/Digital output format = Passthrough

    For all other models (4660/4661/4662/4670/4801) you can leave Settings/Audio/Digital output format = Auto

    For ALL player models (including non-Ultra models) you need to disable all sound modes including Volume Leveling and Dialogue Enhancement which are enabled by default in most firmware versions:  During playback Options (*)/Sound settings/Customize sound modes/Volume Leveling or Dialogue Enhancement = Off
