I agree with rharv to change your output source from the Surface Pro.

An alternative output that's suited for live use is any small format mixer with USB. USB will provide proper level to the mixer and have decent converters. This will assure you are matching transfer between devices, give more routing flexibility and small format Mackie, Yamaha, Peavey, Behringer mixers are very affordable and can have effects and EQ. Some even have capability to record performances to an SD card.
