Hey guys thanks for the replies

Have tried disabling all antivirus/spyware/firewall, all network adapters and wifi in device manager and only thing connected to pc via usb is my keyboard,mouse and toneport.

Unfortunately spiking still occurs :

try inactivate booth your wifi and ethernet cards. I had the same problem and so does a lot of people judging from a lot of threads here. isolating the pc from the outside world by inactivating all external comunications solved my problems

it appears a lot of people have problems with windows7 and I havnt found anywhere that line6 recognises this as a problem, and indeed, my computer reports no conflicts. still, my "intel core i7" goes crazy when using my UX1 and having wifi or ethernet active, with intermittent muting, crackling and noise as result.

this is unfortunate as it means my UX1, wich I used to love, now sits unused when I listen to streamed music(spotify is running 2-4 hour a day) or watching youtube. and I can no longer use the UX1/podfarm when learning new songs off the internet..basicly, for anything exept recording guitar once in a while, I'm back to before I bought my UX 1because of what I would consider a software issiue.....none of this was a problem with my old computer running windows XP...sadly, that computer died when the magic smoke exited the fan outlet.....

good luck

Just a thought - try temporarily disconnecting your computer from the Interent and then disable your real-time virus/spyware checking. Do these spikes still occur?

Of course, while your virus checking is disabled, avoid connecting any external media (e.g. usb flash drive, CD, etc...) to your computer.

Hi there,

Was going to open a new thread but this sums up my issue pretty well so i thought i'd post here, sorry if I shouldn't.

Anyway to begin taken from Dxdiag : Processor: Intel(R) Core(TM) i5 CPU 750 @ 2.67GHz (4 CPUs).
I am on Windows 7.
I use a toneport ux2 as my soundcard.

When using a programs such as Podfarm, iTunes, Cubase the core of the 3rd processor will always spike. Even if the programs are not using much CPU (blank project in Cubase etc)

On a bad day, for example if I am using CPU heavy programs at the same time as iTunes for example the spiking will crackle the audio, when it spikes.

I have attached some screenshots to show

System Idling/No Cpu heavy programs or audio related programs.

Spiking with podfarm

Spiking with iTunes

I have done everything already suggested in this thread drivers etc which have not stopped it.

Looking forward to a reply, please don't hesitate to ask for more info.

Cheers!

EDIT: Just thought i'd add. I've been using my toneport with this computer about 1.5years. I also experience and have experienced sound drop out (no way to get back but restarting) and BSODs. The sound drop outs used to be quite frequent but last ~2months or so don't know why seem to have slowed down (haven't changed anything in my system) BSODs are irregular.

Only other thing is if you turn on the the computer with the toneport in and phantom power on the sound will be distorted, sometimes possible to fix by unplugging and plugging back in. Possible USB power issue?

Anyway had these issues for a while so its not stopping me using the device. But it would be nice if it didn't happen

If the the CPU spikes do not seem to impact your performance or workflow then I feel that this is normal for a multi core CPU.

Using the optimization guide that I linked you to previously will be your best bet to reduce unneeded CPU usage.

Hi,

To be honest I don't experience any severe issues with my computer's performance due to these spikes. I haven't done any recording or super intensive stuff though, so it's really unclear as to how it might impact my computer's performance under a high load. I imagine that having a CPU core constantly going up and down wouldn't be helpful for performance during seriously CPU intensive tasks such as recording. As noted, I'm also somewhat concerned that my CPU constantly cycling up and down like this could hurt its longevity down the road.

To aswer your question, then, it doesn't sound like anything is wrong- the problem is purely related to my reported CPU usage.

What kind of problems are you experiencing with the audio when using the UX1? It is one thing to experieince spiking in your CPU just by being connected, but when does it affect the performance of your computer. If you are streaming audio though the UX1, does the audio sound like there is something wrong?

The UX1 and the other sound card you mention will be like apples to oranges unless it is also using the same Line 6 audio-midi driver. This may just be the nature of our drivers working on your particular system with those specific hardware specifications, but in order to fix something, we need to know how it is adversly affecting the performance of the system.

Hi,

To clarify, those driver updates and tests were all done *without* the AMD USB filter installed. I uninstalled, did the updates, and then reinstalled it at the end. I'll remove it completely again.

Updating video drivers was a good suggestion, and they were out of date. That has not fixeed the issue, unfortunately.
