Loop auditioneer displays multichannel files (3 or more channels) but playback doesn't work.

    Does your default audio device have that many channels? LA presently doesn't do any downmixing on its own, but just attempts to open the audio stream with the number of channels present in the file regardless of your device actual channel numbers. Anyway, I'm currently reworking the audio system of LA.

    Hello,

    No my output device is stereo. Shouldn't I still hear the audio from the first two channels?

    No, it won't work since LA tries to open the audio stream with the exact number of channels in the file and likely silently fails. Currently there's no check to find the limitations of channel numbers of the device. I'll either have to implement it now that I'm reworking audio output or add some kind of downmix feature.

    Most of the time I only need to hear the first channel (close mic) so if there was a way to turn off the other channels or down mix that would be great. BTW I reimplemented some of your loop search algorithm as a lua script in Ardour - https://www.youtube.com/watch?v=-LZ4Rvf4ITM

    The 0.8.6 version should now handle the audio stream so that if too many channels exist in the audio file the device will only try playing back the number it can handle. The excess channels won't be played at all.
