-serial number: YJ008T426327
-device ID: KWA088426327
-software OS/version: current, which works, is 9.4.0 - build 4210-46. problem is with 10.0 build 4177
-does this issue occur on a specific channel? if so, what channel and what version/build is the channel?

-tracker ID when this issue occurs

(possibly others, didn't test any more after the OS reversion fixed things)
Nothing but loud pops and clicks.
The following formats did not experience an issue and played fine:
To resolve the issue, switched the audio away from the specific settings below to autodetect. This eliminated the pops and clicks, but the auto-detect did not work and everything was rendered as PCM stereo audio regardless of formatting.
-what is your audio set to
Audio mode (Auto(DD, DTS))
HDMI (Dolby Digital, DTS)
