Comparing the Behringer U-PHORIA UMC202HD vs UMC204HD audio interface (works on Linux too!)

This summarizes the differences in features and usage of the UMC202HD and UMC204HD USB DAWs. An additional perk I forgot to mention: they work "out of the box" on Linux (but see details further below for some gotchas)! You can find both models on sale here: https://amzn.to/2KkY2c4 (202 model) and https://amzn.to/2TawfOg (204 model).

Linux users:
* If you want to use Audacity on Linux with this device, you MAY encounter a bug where Audacity takes a long time to start up. I have reported the bug here, including the workaround (launch "pavucontrol" before you launch Audacity): https://github.com/audacity/audacity/...
* There is also another small bug that you may encounter with PulseAudio. Details here: https://gitlab.freedesktop.org/pulsea... (workaround: to fix the issue, you can sometimes simply launch pavucontrol; otherwise you can restart pulseaudio with "pulseaudio -k").
