Does jcally jm6 pro might cause performance issue

when you say your phone is lagging it is either processing too many tasks, background apps perhaps, or the wireless connection is not strong
a bit of trial and error, starting with restarting etc...
also
when attaching a usb dongle my android low end A32 asks which of my music playing apps needs to take control of it, I guess that they have got inside the OS to do that so that they can bypass the android audio processing. Just general android audio should work for apps that dont process their own audio but..
you might want to try accessing Developer Options under settings, you need to google how to do it, I cant remember and I believe it varies from phone to phone, there are a lot of them dont mess with them however
you could set Default USB configuration to MIDI (mine was set on something else, but is mine is working and works on MIDI, likely not the issue)
you could make sure Disable USB audio routing is OFF (mine is set to OFF, and mine is working)
if you think its the JCally you can get a cheap dongle for 5 bucks to see if the problem is still there

Ok so I tested ur settings and yea it didn't work
And i also forgot to mention about like the cracking noise sometimes as well

something is broken
factory reset phone, back it up first
try a different dongle on the phone, if it works throw away dongle
try the dongle on a different phone, if it works throw away phone
if it doesn't work throw away both
