I get an 'Unsupported audio format' when playing HD Audio (LPCM) inside an .mkv file. Works fine with .mt2s files. What gives? Just bought PowerDVD 21 Ultra today.

Go to Player Settings > Video, Audio, Subtitles and then click the More Audio Settings button. Check if the "Exclusive audio output" option is selected. If it is, deselect it.

Already tried that. Sadly, that makes no difference.

To recap:

1) The same LPCM stream plays fine when muxed inside an m2ts container;

2) when played from an .mkv, however, PowerDVD reports 'unknown audio format' on the same LPCM stream, but ONLY when muxed together with a 4K video stream.

Same audio stream...so you created the MKV file yourself? There must be an issue with the file that is causing the error. Try converting it with handbrake or send the file to Cyberlink so they can look at it.
