Probably faulty wiring. Try looking inside or returning for new one? How long ago did you get it? Warranty expired?

It has to be some interference between the computer and the amp or a grounding issue( plug both the amp and computer to same outlet to see if it goes away). Either way a Dac would probably* fix the issue.

im using same power outlet but doesnt work. but im not sure what i should do since i got conflicted replies here. either dac would help or its faulty wiring from my amp :/

Agree, amp seems to be fine if it works for other devices. DAC will be nice to have whether it solves the issue or not.

 

[cmander10]

Probably not amp. That would be last thing to check. Most likely connection between computer and amp.

alright thanks appreciate replies from both of you . i guess i will buy the modi one since its the cheapest i can find atm

 

[cmander10]

Modi is highly recommended for its price. Would have to spend at least double to get noticeable difference in dedicated SS DAC. I'm getting one myself soon.

Have you tried lowering the volume on PC (like set it to 1% and make up for it with higher amping)? I'm thinking that you computer might be giving too high voltage to the input of the amp, with some amps it might lead to clipping.

 

[maidos]

alright so i tried a new approach. after the suggestion of using the same outlet i tried something tad different. i used power extension to plug to the wall poweroutlet and used my amp power cord to connect to the power extension instead of the outlet wall and the buzz noise is almost not there
 
Before at volume 20 i could hear the buzz noise
After at volume 50 i could her the buzz noise but it isnt as loud as before so im quite happy now

 

[cmander10]

Definitely a connection issue. Perhaps a power strip will help solve the issue entirely.

 

[maidos]

i guess i forgot to let u know aswell that every time my mouse moves theres additional noise., kinda like zzzz noise
while the other noise is constant and jjust regular buzz noise.
but isnt power strip and extension the same thing?  which is what im using now for my amp.
anyway will go ahead ordering a dac now thanks

 

[cmander10]

Oops, I was thinking of a power extension cord.
 
Do you know the workload/percent your CPU is at and the model? Something must be up with the connection or electric noise from computer.

 

[maidos]

workload is like at 10% average. my cpu is intel xeon 1240v2 and my motherboard is pretty cheap one. not sure how good the onboard audio chip it is
msi zh77a-g4

 

[cmander10]

Most likely motherboard then. Modi should take care of it.

I had the same problem. It's likely just noise that's amplified via your amp. You won't notice it by plugging headphones directly into your computer. You can fix the problem by buying a DAC, internal or external doesn't matter.
 
Again, I had this same exact problem and it's likely not a problem with your amp.
