Hi, 

My playbar seems to have developed an issue with decoding audio coming in over the optical connection. Not constant, develops after about 30s of working fine, then stutters for 2-5 seconds every minute or so. 
 

so far I’ve tried:

changing all output settings from pass through/pcm.

changed input settings through all of the options.

have tested each possible combo of input/output.

Swapped optical cables

changed to an external ARC to Optical converter

removed surrounds (they weren’t stuttering as it was only playing 2.0 audio, it’s all on the playbar, but others had suggested it as a fix) 

All of the above still resulted in regular stuttering. It reduced if I used PCM but did not disappear. 

I have tested the optical out with an old digital/analog decoder and had no problems, I have also plugged the arc into my Sonos amp and have no stuttering with that (that was previously plugged into the external arc/optical converter to verify that audio was clean)

everything I’ve done points to an issue with the playbar, I’ve had no issues with the playbar for all the years I’ve had it, this issue seems to have been introduced recently, has their been an update that broke something?
