Debian Linux: 10.11
Audacity: 3.1.3 Using AppImage
ALSA driver: Using HW access
Audio microphone and playback.
I am attempting to use overdubbing in a Linux environment with two tracks on Debian. When recording the second track, the first track is heard in the headphones. After recording the tracks, the net result is that on the combined playback there is a click, silence until one of the tracks ends, and then the remaining track can be heard. If each of the tracks are played in solo mode they can both be heard individually.
Things that I tried: I installed a windows version of Audacity and was able to get the overdubbing to work as expected. Also the project file from the Linux machine was transferred to the Windows machine and playback exhibited the same results as in Linux (silence is combined playback and normal playback in solo mode). In the reverse, generating a project file in Windows and transferring to Linux I was able to hear both tracks properly in the playback in the Linux machine.
Also installed audacity in the same Debian Linux running under a VM and experienced the same results as the bare metal machine.
(note: Overdubbing is enabled and software playback is disabled).
So can anyone offer a suggestion on how to get overdubbing to work? Please let me know if I can provide further information. Thank you for any assistance.
