I got exactly this issue too. But I got tired of trying to figure the problem out and started to accept this REALLY ANNOYING highpitched noise. But damn it bugs me to hell!

So, what's happening?

Gonzalo you have the patience of a saint.

I have the same issue - the identical noise as recorded by Gonzalo. It doesn't occur on the UX2, and I use my UX8 as a mixer/preamp and run direct to a power amp and out to speakers. It doesn't show up on the cans or in recordings so i am having trouble believing its a grounding thing. I get it the moment i switch the UX8 - I don't anymore run gearbox.

L6 doens't seem to have posted any permanent fix but i see the Ux8 has been discontinued.

That's one BIG gripe i have with Line6, by the way: Fellas: STOP discontinuing and reissuing hardware! I have had it happen about five times ove rthe last eight years: POD, Pod Pro, Floorboard, Gearbox and now UX8. STICK WITH A PRODUCT can't you?

Just to be clear.. The high quality usb cables with the ferrite filters did not resolve the bug.

Dang it!

I have the same issue, I'm in MAC OS 10.6.6, on the latest 64-bit kernel driver..

So I made a lot of tests, and my results are:

It has nothing to do with electrical things or fans or monitors or amps.

This is only on the Main output, not on inputs and it is not recorded at all so that tells.

This hiss is only present on the main outputs and not in the headphones of main outputs, I noticed that its volume is constant and completely independent from the main volume knob, and it only happens in channels 1 and 2, main outputs, as a matter of fact, the hiss keeps sounding when you start any app that uses the UX8 on "main outputs" channels 1 and 2 even when the sound output on your app is on 3 and 4...strange.........so for now I'll avoid main outputs for everything, its not the best solution since the main output knob and mute button on the front become useless, though I can use the main output headphones for cue monitoring on ableton live......good thing that from the UX8 I connect to a mixer which then go to the speakers, that way I can control the UX8 Ch 3-4 volume output on the mixer, so for now maybe the solution is to use the other 6 outputs.

This result tell my logic that it is soft code related, if not it would be present in all outputs or at least all the time and not only when the driver is used by apps.

Don't know if this is also present on the 32 bit version, didn't even tried that, I saw no point in downgrading to 32-bit, so my UX8 was unused for 2 months until this latest driver.

Are the symptoms the same on your side?

I hope this tests info helps to get this fixed on the next driver update. ASAP. please L6.

Hello all who have read every post and are still left with a sense of ???

I have the same noise, only starts/stops when I use Gear Box, (I don't use other monitoring programs, recording done with a separate studio output interface). As long as nothing is plugged into the outs when recording, I am golden. (defeats the porpoise of the hardware though.)

Tips to Try:

- Shielded High-End USB cable on it's own USB card.

- for studios: Pull fresh wiring from the breaker for your audio and separate pull for your computer. (I used armored cable)

- some devices can receive line noise when when not sharing grounds.

- Power conditioners can help if your in an area with oscillating line voltage, especially when the sin-wave starts expanding.

- Recording studios should really have their own wiring and grounding.

- on the road musicians: Heavy Duty power strips, high quality cabling and not routing audio around power will reduce most noise.

- (plausible tip but questionable) small washer magnets placed in line can help with line noise. (herd the tip from a master electrician friend.

For me I have this problem, unsolved if I use GearBox. But one constant I do see, and am sad to say; I have a Behringer Mixer UB2222FX. The Behringer might have grounding issues, or other compatability issues, because I also get humming when connected to the UX8. This is a good sign of line noise cause by a grounding.

My advice to Behringer users. Add an isolator or insert a pre-amp between the UX8 and the mixer, or try a different mixer (ask a friend).

Your Recording Studio Friend,

Joseph Lang -FlatLine Studios-

[Edit] add - On my Behringer Mixer, on the back are FX/Sends (tip send / ring return) I purchased an FX Snake (a series of 1/4 Y cables that share a ground and ring goes to one end and tip to another) This reduced nearly all of my line noise, HOWEVER I now have volume control issues, but that is because the inputs are LINE inputs, according to the UX8 hardware via GearBox, You may have to manually change them to Mic/Inst to change this. The volume issue is CLIPing input and low output sound, sounds over driven. But no high pitched noise and GearBox is still not being used, so therefore no problem with my Behringer mixer.

Hi Fellas:

It's definitively some kind of electrical interference with preamp gear. I've disconnected and removed systematically all devices connected in the system, and the only thing that got rid of the noise was to:

Have a surge suppressor strip connected to the wall, all miscellaneous gear on the strip, the UPS connected to the strip, and the computer, UX8 and Power Amp. connected to the UPS. Direct all computer audio through the UX8 and leave the mixer out of the equation, being the only variable item that I can live without.

Seems "preamp" related then. I've connected an old Gemini DJ preamp instead of the mixer and also makes noise. Changed the Power Amp to powered speakers, with the mixer or the preamp, and the noise was there.

So, my system is noise free now, and mixer free...

I had the same issue.....

I found that the Mic channels 5 & 8 are hot even when nothing is plugged in to the channels.

I muted Mic Channels 5 & 8 and the high pitched noise went away.

The sad part is I feel I just lost two Mic Pre-Amps but at leased I got rid of that God Awful noise!

Hope this helps...... may not be the same issue all of you are having but it solved mine.

Hi:

I'm the originator of this post, and I've halfway solved the problem.

Seems to me that is electrical related. I had to ask my electrician for an entire electrical phase just for my home studio, and the noise is gone.

The same electrician said that any place in the same electrical phase that have dimmers, "energy saving" and tube fluorescent lights, vaccum cleaner, CRT TV, etc. would probably have some kind of noise on audio units including the UX8.

So, my solution was like killing the dog to get rid of the fleas, and I don't know really what was the cause of the noise. My entire rig is silent as a graveyard now, and I found it useful in the end by getting rid of other less unpleasant noises as well, but not too many people are willing to rewire their homes to fix a unit's apparent flaw.

I did all sort of tests on the unit, and at home made me build a new electrical wiring from scratch to wipe the noise, because everything else failed to get rid of it, but using it in a couple of gigs as a sequencer router, away from home, with normal club wiring, the noise was not there. So much for the electrician's theory! A club with 20 TV sets, dimmers, neon lights... Weird!

I'd say that it would be a good idea to re-post the topic, so someone at Line6 finds out how to really get rid of the problem without having to spend more money on the house's wiring than the price of the unit itself.

I'll post my sample of the noise there!

Line 6, this product has problems. We would sure appreciate an update.

Re: UX8: High pitch noise whenever opening any audio applications, MAC OSX

I hate to be a part of this post, because I really love my UX8, Gearbox, and Pod Farm. But unfortunately, I am having the exact same problem. Something else I've noticed, when audio is not playing, but any audio application itself is open, the same high pitch frequency is audible in my headphones if I crank the headphones up beyond normal listening levels. If I have the volume in my headphones at a normal level, it sounds fine, nothing noticeable. As soon as I power up the monitors, the high pitched frequency is is in the monitors, but only if any audio application is open. Or again, if I crank my headphones, exact same frequency. Any update on this issue?
