Hi MasterHurrikane13,

Can I ask you a few questions:

* What CPU does your computer have (model and speed)?
* What do you have the USB Buffer in ITCH set to? This is on the Hardware tab of the Setup screen.
* What do you have the Headroom set to? This is in the Mixer tab on the Setup screen.

Also, could you please run a DPC Trace report and attach it to this thread? There's an article explaining how to do this here -> www.serato.com (click list).

Thanks.

thanks for responding michael, i will run these tests tonight....

honestly tho, i have decided to sell this ns7 unit, i just purchased a one month old used ns7fx unit and i hope to get better results with that, i am beginning to believe i may have a defective ns7 machine.... my headphone jack has inverted audio playing through it when i plug my headphones in all the way, i have to plug them in half way to hear audio correctly... guitar center rep said the item could be defective off the factory line.....my new ns7fx will be here in a week.

Hey MasterHurrikane13,

It's possible it could be faulty hardware, obviously we'll know for sure when your new unit arrives. If you are able to try what I mentioned earlier that would be great, so we can see if it's a setting in the software or something on your computer that is causing this problem.

Thanks.

bought a new ns 7... thhe screeching is gone but i get the 2 second delays again on multiple laptops.

Hey MasterHurrikane13,

The first thing I'd suggest is that you try following the steps in these articles:

If that doesn't make a difference, can then please run a DPC trace report by following the steps here -> www.serato.com. Once you have the report, can you please attach it to this thread.

Thanks.

i have to run the dpc trace report tonight.... but i was doing a gig the other night, the first 2 hours were fine then the audio started popping and sounding watery...., switched to an emergency song, restarted pc and ns7 sound went away for 25min then it came back, then i had to switch to SSL and my old denon s3500 tables.....

Hi MasterHurrikane13,

Sorry for the delay in reply, I have been away from work.

Were you able to run a DPC trace report? If you have, are you able to attach it to this thread?
