Hey , I have Ur44 , when I plug my guitar to any input I can hear the guitar, Accept line 2 , i can see the monitor light when I increasing the gain of this line and play, BUT still cant hear anything, please help
You probably solved it by now but I would check dspMixfx if the channel is activated.
Also you should probably route input 2 to a channel in your DAW or monitors.
Hope it’s not a broken input but if you still have issues please elaborate on your setup (PC/DAW/iPad etc.)
