Solving playback issues

[stinerman]

After an update to OS 14.0 my 4660x no longer plays any file with AC3 or DTS audio. I tried with my soundbar and the built-in speakers to the TV. No luck on either. I transcoded to Vorbis and AAC and both work fine for both 5.1 and 2.0 content on the soundbar and the speakers. All files are in MKV format and have varying video codecs.

I know it was the OS update because I could watch these files with no problem yesterday. I received the update early this morning and now I can't play AC3 or DTS audio.

Roku device: 4660X
Roku OS version: 14.0.4.12221

Any help anyone can offer is appreciated.

I agree, I'm having the same issue on my 3 Roku Ultras 4670's no sound on any files with AC3 audio.

After wasting a couple of hours resetting EVERYTHING no sound.

Same software version & build.

Glad I found your post so I know it's not my issue here. Thanks for that!
