    Multi Channel MP3 and AAC - maybe general confusion

    I lately experimented with Multi Channel Files.
    I have a couple of 5.1 Flac's.
    When converting them to MP3, i get always stereo, even if I set up Channels to Auto and then Channel Count and Channel Mapper to 5.1.
    When playing with AAC, and choose 3 or 4 channel, it crashes:

    Error converting to m4a FDK (AAC), 'D:\XXXXXX.flac' to 'C:\XXXXXX.m4a'
    Error writing audio data to StdIn Pipe [clEncoder::EncodeBlock]

    Is there anything I'm doing wrong, especially with MP3, and is there maybe a overview which codec supports which Configuration?

    mp3 only supports 2 channels.

    m4a (FDK) can encode 6 channels, but not 3 or 4.
