    Hey, guys

    Is it possible to upmix stereo to 5.1 over HDMI? In Kodi I’m able to do this and while testing Pi Musicbox I noticed their system featured this option.

    I’ve done a bit of research into ALSA and found some info, specifically:

    Then add the following to your ALSA configuration file of choice (either /etc/asound.conf or ~/.asoundrc):

    pcm.upmix51 {
    type upmix
    slave.pcm „surround51“
    delay 15
    channels 6
    }

    But this doesn’t help. Any suggestions?
