Presonus Statement regarding Audiobox VSL Issues

This message was edited 3 times. Last update was at 04/02/2013 16:24:04

I purchased an AudioBox 44VSL a few days ago, and also have audio drop-out problems

It makes no difference, if VSL is running or not.

I found out that a process called "system interrupts" is causing CPU-load and CPU-spikes, whenever the AudioBox is connected.
I think the chance is high, that this is causing the drop-outs.

You can't see that process in the task manager, only in the "resource monitor" of Windows 7.
When I unplug the AudioBox, the "system interrupts" goes down to 0% CPU, so it's definitely the AudioBox causing the problem.

Btw, I had no audio-droup out problems with my last interface, an M-Audio Fast Track C400, using the same system with same settings.

I will try the suggestions above, but actually I would like to have an interface which just works, without having to mess around with it for hours.

I am using a lenovo notebook with IntelCore 2Duo, 4 GB RAM and Windows 7 32-bit.
Buffer size is set to 1024 or 2048 samples, driver version 1.2

EDIT: Installed and tried the 1.2.1 beta driver.

Less drop-outs, but still not completely gone.
"System interrupts" still eating CPU like crazy.

Hi All,i have recently upgraded to window 8 & on windows 8 the usb &vsl drivers are not compatible..is there going to be an updated drivers for windows 8??

The latest drivers are compatible with Windows 8. They definitely need to be improved but they do work with Win8.

Great news! This seemed to work for me. I uninstalled everything for Audio Box VSL drivers etc. I am running windows 8, and have had the same issues with massive cpu spikes,pops, and dropouts. From everything I have read so far there is an issue when you change from the usb port you installed the program on. After a reinstall at least everything is working. I am showing higher latency readings after the reinstall (don't know why) but everything else is working great. It doesn't seem to be affecting performance on my computer. I tried the Legacy driver, but did not get admirable results with it. Thanks for the great info. Hopefully this be a final fix for me.

What I'd really like to see is an Remote interface to the VSL44.
I wasn't really getting a lot of use out of it.
So I thought I'd try using it pipe 4 analog Aux Monitor sends through to allow easy control of Dyn & EQ for each mix from the stage.

It Works but I have to walk around with my laptop and a long usb cable to hear the monitor of choice while correcting the eq.

Wish I had bought the 1818. With that I could leave it in the control booth and use the Remote Ipad to set things...

Oh well..... Anyone want a slightly used AudioBox VSL 44?

I own an AB1818, I bought it based on the excellent quality and flawless reliability of the SL 1642.
It is disappointing that Presonus can develop a new line of speakers, new mixers and smaart integration, but are not able to make the nessary repairs/updates to the AudioBox product line.
I use Presonus for many different events weekly, so my needs are simple for my AB1818, and it's been requested numerous times by AB users, VSL Channel Labeling.
Yes, I know I can use Studio One instead of the VSL app. For labeling, but it doesn't have an ipad app that I'm aware of....

So this is how I used my AB1818,
Stand alone, AB1818 with 8 wireless mics

With my StudioLIve mixer, as a side car into the various inputs that the board has.
This combination allows me to run a total of 28 wireless mic.

I also keep a Project Studio installed in the main rack as my back up.

Thanks for reading my post, I am and will be an avid user of Presonus gear, and hopefully Presonus will hear our reasonable requests.

well,

I had not used my 1818 for a couple of months (away on a work project) - however, when I came back I fully expected to have found a resolved issue.

No dice. Running a brand new mac mini and I cannot even record a single chan. mic without unusable pop and clicks.

I have VSL turned off and I am not willing to reinstall my operating system to go back to kitty cat or whatever the last one was.

I am afraid that this is going to go on ebay or craigs list or the closet in exchange for something that works.

Am I missing something or are we still fighting this same problem?

Thank you,

Joe

Update: For anybody else trying to get this to work, just turning off VSL did not help. However, doing a reboot and not ever loading the VSL program helped a lot. At least on a couple min test. I will update this later as I plan on doing a decent bit of playing around today.

Presonus, any news on this?
I am also disappointed with my AB1818. I posted about noise, pops, drops, and clicks on the S1 forum, but now, after reading more on the AB forums, I think it might be my AB1818 that is causing me problems.
Can ANYBODY offer me any info?:

To all of you watching this thread that are having issues, PLEASE start a Tech Ticket so that Presonus might get all the information into the tracking system. Each case is different and in order to get a fix for all the issues they need to KNOW all the issues..

If you have already submitted a ticket and NOT gotten a satisfactory conclusion, please re-submit or re-open your claim. This will help us all.

I'm using Windows 8 with the VSL. Where are you seeing it's not compatible?

It has now been 6 months since Presonus acknowledged the problems with pops and clicks with the VSL interfaces. They said it was a high priority to fix the problem but after 6 months still nothing. I gave up using my Presonus interface and switched back to my old Edirol unit. It is a shame because I really liked being able to add effects on the headphone monitor. It would be nice if someone from Presonus would give us an estimate of when they expect a solution.

This is good but is it applicable to 22 vsl ?
Thanks

Hello
I had this problem of pops and cackles but after tuning the windows i have no problems or almost no problems. The trick is in conserving CPU.The article on how to optimize windows for audio is helpful
Thank you Brandon Hays[b]

I'm not just annoyed, I'm pissed off at myself for not finding out about this problem before I purchased my 22vsl. I still have time to return the unit but I'll never get back the time I wasted trying to stop the popping and clicking. Presonus, I thought highly of your products. Now....let's just say I wish you well solving this problem.
