I have just started using qtractor 0.9.18 - AppImage on Sony Vaio laptop running Mint20. The file exported (I have tried various formats) does not play, no sound at all though the progress bar in media players such as VLC does run. I have loaded these files into Audacity, which results in a wave-form displaying, however Audacity will not play the files either. I am using the same export file choice as I have chosen in View/Options/Audio/Capture Export. Am I exporting wrongly, or have not set up qtractor properly? Thanks...
re. exported audio file not playing
The exported file (or any other audio file) would not play on my laptop until qtractor was closed! Must be that qtractor takes over the sound system, presumably because it switches to using JACK instead of ALSA?
exactly. it is JACK and not qtractor per se that takes over the sound device.
if you want to other players (audacity, vlc, browsers, etc.) get a chance at all, while JACK is in charge, please learn to use modern JACK2 with D-BUS enabled and let the PulseAudio JACK modules do the trick.
cheers
