UX8 - Glitches, artifacts, click and pops
by georgewkemper on 2011-09-06 15:27:52

Hello!

I recently bought the Toneport UX8 and was really excited about all the features and the included software. Unfortunately, I haven't been able to get it to work.

The sound that comes out is always "glitchy" (that's the best I can describe it). I'm attaching an mp3 of some audio I recorded using the UX8 that demonstrates the problem. It has made this sound both in GearBox and in Logic Pro 9. The audio sample was recorded in Logic and is clean (no plug-ins or processing).

It also makes this continuous glitch sound when I use the UX8 just to listen to songs in iTunes.

Here's information about my system:

Computer: Mid-2009 13" MacBook Pro

OS: 10.6.8 (Snow Leopard)

Line 6 Driver: 7.0.9 — I also tried 4.6.8 but it didn't make a difference

I'm not using a USB hub. I have the Line 6 Audio/MIDI buffer set to "Extra Large" and Logic's buffer set to 1024 ms.

I have read and followed the USB Audio Troubleshooting advice here: http://line6.com/support/docs/DOC-4282

Anyand all help is appreciated! Thank you in advance.

George

Hey georgewkemper,

Have you also tried using different buffer size and sampling rate combination to see if it "glitches" change at all?

Please try removing any additional unnecessary USB and firmware devices from your computer when troubleshooting this issue. Make sure to connect it directly to a USB port and not a USB hub, extension, or keyboard of any kind, preferably connect it to a USB port on the rear of computer. Try testing it using additional USB cables and every USB port available.

In addition make sure that you run the latest MAC OSX drivers:

MAC Drivers : 7.0.9

If you receive the same stutter on each USB port, then I would suggest trying it on another computer so that we can try and establish if the problem lies with your original computer or possibly the hardware on the Tone Port UX8.

Be sure to install the drivers for the particular operating system prior to testing it on the second computer.

Please let us know your results.

Hi Line6Don,

I wasn't using a USB hub at any time, and I tried both USB ports on my laptop. I also made sure I had the latest driver (7.0.9) installed.

I did a lot of searching on the forums for similar problems before posting this but didn't find anything useful. After posting it though, I discovered the following thread:

http://line6.com/support/message/160726#160726

Theproblem in that thread is the same one I was having, and the solution that davidleeking discovered (changing the sample rate from 44.1 to 48 and then back to 44) solved my problem.

I would suggest putting this in the FAQ for the UX8. I drove myself crazy trying to solve the problem, and when I found out resetting the sample rate fixed it I thought, "Really? That's it?" I wish I could have saved myself the headache.

Anyway, thank you for your help. My UX8 is working now and it's a blast to play with.


Regards,

George
