UX8: High pitch noise whenever opening any audio applications, MAC OSX
by Factory003 on 2009-05-02 14:30:15

Every time either when I run Logic, iTunes, or just any type of audio through the web,
I get this slight high pitch frequency with some kind of periodicity pattern.

It's extremely unavoidable & impossible to deal with. At first, I thought it was a defective
unit & sent back for a new one, but still getting this unbearable slight high pitch frequency

with the second unit. If I had to describe the sound, it would be a consistent high pitch pattern,

something of a disc spinning. Very digital sounding. I removed all peripherals from my rig, including

external drives, printers & scanners & only had the UX8 plugged in, & still had the same problem.

I bought a new USB gold plated cable & plugged into all USB ports, but still same result.

I've gone through the monkey preferences & experimented with different settings

but nothing seems to work. I'm running the UX8 TONEPORT on a 2 x 3 GHZ Quad-Core Intel G5 [OS X V.10.5.6], with 10GB ram.

I've also tried all troubleshooting listed on this sight. It seems like other people have had this issue but nothing ever is answered

Hi,

How are you monitoring from the UX8? Headphones? Speakers? What exact connections are you using (outputs from the UX8, inputs to your monitors)?

If you are using speakers, one thing to try is use a TRS / stereo cable to go from your UX8's main outs to your speakers. These are balanced outputs so if you do not use TRS cables, you wont have a balanced connection (if you have studio monitors there is a good chance they have balanced inputs). This could be the source of your problem.

Thanks

Thanks for responding.

I'm monitoring out from the UX8 to my powered speakers, [V8 KRK's].

I'm going from the UX8's main out's straight into my monitors using

TRS stereo cables. I've basically exhausted every possible angle & I

just can't figure out what's creating this sound. It's a very high pitch repetitious

digital sound pattern that's very consistent. I don't necessarily think it has to do with the

balance connection of the monitors.  Do you think it has something to

do with some sort of clock sync? I've experimented with all the settings

for hours, but still always hear it.

I'm at a loss here. Not sure what else to do.

Factory003,

We spoke on the phone yesterday and I was able to reproduce the noise that is being discussed here with our own test UX8.  Upon inspection, the test setup was of a UX8's 1/4" outs w/ UNbalanced cables connected into a Eurorack mixer which was connected to monitors via Balanced cables.  This is the setup that produced the high pitched noise whenever the computer accessed the ASIO driver (such as lauching Ableton).

I then performed a test today with the UX8 connected directly to the monitors w/ Balanced cables, launched Ableton, and the noise was gone.  The balanced cables connected directly to the monitors got rid of the high pitched noise.

I'm not sure why you are still getting the noise, but you may want to check your cables or try a different set.

Regards,

Line6Hugo

Hey Hugo,

Just out of curiosity, were you hearing some sort of consistent digital pattern
along with the high pitch sound when you were experiencing this noise?
Very strange, because I’m using balanced cables going directly into my
monitors, but I’ll buy a new pair TRS Balanced cables & give it another shot.
I’ll keep you posted.

Thanks.

Yes, when I heard the noise it was a high pitched consistent digital pattern when I was NOT using balanced cables. Please keep us posted after testing different cables.

Regards,

Hi!

Got my brand spanking new UX8 2 days ago. What a device! But I'm getting the same problem reported in this post... A very annoying high pitch sound through my Yamaha HS80M Studio Monitors when going into Cubase or playing any sound from in windows.

I've just bought 2 x XLR Male (Yahama HS80M) to 1/4 Jack (Line 6 UX6) BALANCED cables. I'll give it a go this evening and feed it back.

Thaks for the advice. Fingers crossed!!!

Line6Hugo ---> The balanced cables worked for me! Thanks!

I'm experiencing the same high pitch noise through my UX8 when I launch "gearbox". My setup is an Alesis RA150 Amplifier, Alesis Monitor One passive speakers, iMac Intel 2.0. The noise appears even with balanced cables directly from the UX8 outputs to the amplifier using the UX8 as mixer. I have a Behringer Xenyx 502 which I'd like to use for monitoring various sources, but just make the noise worse.

Help!

Chalo

I tried the balanced cables solution and no luck. Other suggestions?

High pitched noise from toneport ux8 here too, connected with balanced TRS/XLR cables directly to Mackie HR824s.

What's the lates word on this?

Same problem here.  High pitched noise when sending any audio to the speakers from my new 27" i5 iMac.

Double whammy with my iMac, the high pitched noise AND the UX8 isn't fully supported (read practically unusable) on Snow Leopard.

Come ON Line6!!

Here's another thread on the noise:

Same issue this side with an UX8, I've also got an UX2 which runs absolutely perfectly...frustrating!

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?

Come on Line 6, after purchasing these units we insist on an update to make them run properly, certainly one can't expect to purchase UX8's and deal with these kinda issues from the word go.

Same problem here... I can unhook my monitors and still hear it thru the headphones.

I have had my UX8 for I think over two years... (I Love It!) I never noticed a High Pitch noise untill after an update.

It seems to be apart of the ASIO driver....

I used to think it was just in the monitors but have recently learned that it is being recorded on the tracks (since I learned how to properly mix) www.homestudiocorner.com

GREAT SITE!

So I need to get this problem resolved. I think I will try to go back to the old driver....  If I can? I will post the results when I have results.

I just got rid of my high pitch noise!

I muted mic output 5 & 8... it went away. I tried all other channels and there is no high pitch signal... Its only on Mic 5 & 8

If you select line inputs on these channels everything is fine.

I feel like I just lost two Pre-Amp Channels, but at leased I can continue recording without that awaful signal.

I attached a photo of the mutes..

My suggestion is to only unmute the channels you are currently using.

I know this is not a fix.... but it does temporarily get us working again on our recordings...

Line6 Is this a driver problem? Please help your customers with this Awesome equipment you created.

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.

The main output frequence could be the problem, try to check this on audio-midi preferences, this may happens when you are rewiring to a second device

i'm gettin gthis issue too. Mac OSX Snow Leapoard ->ux 8 - main outs to really nice power amplifier and ruark speakers - i'd really like to be able to listen to it without the scream and the digital signalo interference - any news?

- mute thing didn't work for me

- not did switching to 4800hz and back

- nor did updatring to latest drivers

Im having the same problem! Is there any solution on this problem? I guess I've to return my UX8 if you guys on Line6 are too busy making other hardware and don't give a damn about this one anymore.



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

One year ago since I wrote the last entry and still no reply or fix on this problem. Jesus christ! You should be ashamed of yourselves selling this garbage!!!
