I use the Western Digital WD-TV player to watch all my Media Server content. As I can't quantify when this started, I don't know if it was after the latest Win10-64 update (20H2), as I usually don't watch these MP4's that often. I also loaded the K-Lite Codec Pack, just for S&G's, but still no joy.

One thing is, I've re/installed various versions of UMS, in addition to the legacy PS3 Media Server, and Mezzmo, again, all these used to work, but NONE are now on AAC soundtracks. Is there some transcoding option (which I don't see) that will take the AAC soundtrack and re-encode it in AC3 (Dolby Digital), or just about any other audio format, other than AAC? All my other files are Dolby Digital of various kinds, and all work fine. Again, all these files DID recently work, then all of a sudden, ALL stopped playing back AAC audio. As it is, just about all these files are DL's are from YouTube, including my own UL's/DL's), most of the content being tutorials, ham radio related, old PD classic movies, etc. I'm fairly certain that it's not my Denon (AVR-X1500H) receiver as I have a few AAC audio only files that do play. Note that I can play these same MP4's without issue with VLC. Now, these same MP4's play the video fine, but NO AAC audio. Up until recently, I was able to play MP4's with AAC audio tracks without issues.
