Hey! Well that’s the fun part, I did not do anything. ASIO is a native driver in Android.
You just need an usb-c to usb-c cable if your phone has that kind of jack… Or an “OTG adapter” if you want to use the original cable of your DAI
This naturally worked for me with Scarlet Solo and Zoom U-44 and I doubt any recent usb DAI wouldn’t be plug and play like this
Neither of these devices declare that they support Linux or android but they do work…
It takes a few seconds for it to switch when you first plug in…
For recording audio I suggest Audio Evolution Mobile it has most DAW features but not free. For casual recording any voice recorder app is good enough
