hi,

mixrack, surface and editor are latest version 1.53v

i´m useing a laptop as a spare part, when the suface may power down.
for that in the edito i choose the option to control the laptop with the mixrack (third one). so i can controll the mix if the surface break down!
i connect the laptop via wlan, that work perfectly. but if i close the editor-software (exit the program) there is a loud cracking noise on all channels, even too on the mixbuses!

i didn´t tried it with an ethernet cable, so some one maybe would like to check that?

is that a known issue?

OFFTOPIC:
sorry for my english
