Maybe. Just pay attention to whatever is on at the time when the buzzing occurs. Is it a light? AC? Fridge? Bathroom fan? Phone charger…literally anything and everything.

So Ive got a little question, When using the volume knob on my AVR when listening to music I get a sort of crackle but it only seems to happen when its sending low freqencies to the speakers. It is an old AVR and Class A so I presume just due to age I need to open it and get some contact cleaner on the volume knob? Its happens at around sub freqencies
Just want to ask before I open it up 
Assuming it’s happening only when you turn the knob, you have 2 options.
- Live with it.
- Try and clean it.
- You can try aggressively wiggling the pot backwards and forth in the effected range (with it turned off), this will sometimes fix it.
- You can try and get contact cleaner in the pot, depending on the pot this might not be possible.

Just a lil update on my dc offset issue…
I tried the ifi dc blocker thing since it was very conveniently available on amazon (figured it would be better trying it out than having to troubleshoot), and it seems to do what it’s supposed to do. I like that it is very compact and a no-fuss kind of thing. Haven’t noticed any change in sound for better or for worse so that’s good. I’ll make sure to update though if the dac ends up buzzing again. Hopefully, it’ll all be good.

just for reference sake maybe, came across this article by Paul McGowan on the subject:

So I’m pretty stuck right now and I can’t think of anything to solve this issue.
Prior system used was aries g1 w/ spring via usb. Everything worked fine there. Finally switched back to the lampi and after a few seconds the sound would just mute itself (meaning no sound comes through via usb). I’ve already tried factory resetting, fully powering down everything, turning on the dac before powering up the g1, and plugging/unplugging the usb cable. But nothing helped, sound came through and then after a few seconds… no sound. And the g1 has no problem recognizing the lampi dac in its menu…
I even checked the auralic forums but nothing with this specific issue. I sent them a ticket to see if they can help but does anyone here have any ideas?
So was this the first time that you’ve used the lampi with the streamer? Or was it working fine beforehand?
Make sure the button on the front of the Lampi is set to work as USB. If you press it in one direction or another is switches the USB input. You may have inadvertently turned it off.

I was thinking that, or the USB firmware needs to be flashed to work properly with streamers depending on what it’s on now

2nd both the above points, for the USB input to work, both the rear switch must be pointed at the USB input and the front panel push button must be in the correct position.
The Amanero board is also known to have issues with some OS’ to the point they used to have different firmware’s for linux and Windows hosts, my guess is the Auralic is running Linux and you previously ran USB off a windows box. FWIW I never had this issue with mine, it worked on both, but someone else on the forum had to flash theirs.
It’s a very common request, so if it comes to it you can just email Lampizator US and they will email you instructions.

How does it cut out? Is it a clean off? Does it show the music is still playing through on the G1 (time still advancing?)
A few of my dacs would kill signal if the output cables were wiggled or tampered with. It would need a power off/on or cycle through sources. Make sure the outs of the dac are clean and connected well.

First time
Yup, it’s definitely pushed in
Only the AES/spdif input toggle is at the back
I was running it off on a MacBook before so I’m assuming it’s using the Linux part
Ok, I haven’t done this yet
It’s like pressing the mute switch but music still advances
Did all this too. Even put some deoxit
It’s the jlsounds card btw
Firmware is also on the latest for the g1
I assume you’ve confirmed it’s still working directly off the Mac?
If you had a problem with the USB signal it would mute, so a bad cable can do it.
I’d still talk to Lampizator US, he responds pretty quickly, but my understanding is that the JLSounds doesn’t have the firmware issue.

Yup, it’s working fine on the Mac
But the same cable (fta callisto) works fine with the spring
Ok, yeah I’ll try that

The only thing left is to try alternate cables, one at a time. May be a big PIA but thats how troubleshooting do be at times. If not hopefully lampi can help.
Is the g1 usb out only?

Then assuming the G1 is also working on a different DAC with the same output?
You’ll need to talk to BOTH manufacturers, neither is that unusual a piece that they won’t know about issues.
Just send both emails, most manufacturers respond in a day or 2.
As an aside I’d be surprised if the Auralic isn’t a better source for the Amber over AES rather than USB, the clocks on the Amber aren’t anything special. And I’d expect the clock on the Auralic to be better.
No it has other digital outputs but I only have USB
You mean try a different USB cable? Or do you mean all the cables?

All, but starting at usb probably is the most logical. Its a little bit of a “this is dumb why even try it” but it eliminates things which is also important.
Don’t tell anyone I suggested this, but you can use a single balanced cable for a balanced AES connection, it’s just not ideal, really you should use one with the correct impedance, but it won’t hurt anything (will add some jitter) and will get you running.
