I have a Philips Roku TV and the sound regularly gets very hollow and loses all the bass. If I rewind or fast forward for a moment, it corrects the sound. It is occurring with all the apps on the TV. I plugged a Roku stick in, which layers Roku on top of the Roku TV. The sound is normal when viewing through the Roku stick. This only started after the 9.2 update. I am running build 4502-63. The TV is a Philips Roku 8623X.
I'm having the very same issue, sound is hollow and will even skip every other word. It sounds almost like a car with busted speaker. I have reset audio sounds and even factory reset the entire tv. It's interesting that in live TV there is no sound issue just in the roku apps.
Is this issue occurring on a specific channel or does it happen across all channels? In addition, have you tried rebooting your wireless network to see if that resolves the issue and eliminate the possibility of it being a network connectivity issue?
