Problem 2: while playing a jack plug-in guitar, it has two sound come from the monitor(Yahama HS5): normal simulated guitar sound and a noise similar to max volume from small inch amp at the same time

So, here is my basic setting and equipment I already have.
Setting 1:
*Problem 2 exist
Setting 2:
*Problem 1 and Problem 2 exist
of course, the setting 2 is the most suitable way for my preference, but problem 2 is the most I want to solve it cause an intrusive noise while I am playing
Please let me know if there are any reason or solution i can duel with. Thank you so much for the help.
