  1. 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.

  2. LPCM 16/24/32/64 bit?
    Post a mediainfo report of you mkv file here (text format).

    Here is an example, in full (see below). Just a standard 5.1 LPCM audio track. Plays with everything, even with PowweDVD 21, but not inside an .mkv container with an UHD stream.

  4. Could be the Bit depth (24 bits in your case).
    You should check if another working PCM is 24 bits too.
    mkv or m2ts are only containers, but the player fails a codec.
