I find myself needing to DJ over zoom. I need to be able to send microphone and audio out to zoom and have zoom play remote audio as well. I run Ubuntu18.04/Mixxx 2.2.3. Default driver is ALSA. ALSA is configured to disable other sound outputs. OSS is just not working (maybe not installed at the system level???). Also, I don’t want to use multiple cards, but I do have a four-channel card, on which I use channels 3-4 for pre-listen.
How do I configure the system so that a) I can hear others, they can hear my music AND me? b) while avoiding using one card for pre-listen and built-in audio for zoom? I’m worried that in this setup Mixxx or at least audio stack will crash due to issues with clock synchronization - this is why I upgraded to a four-channel interface in the first place. Any advice?
