An annoying non stop high tone when i run Sonar

Did you add any plug-ins recently, like a demo plug-in? If not, then you should run a full anti-virus scan. 

Is it coming from the OctaCapture? Does it happen with the OctaCapture unplugged?

try bypassing all fx and see if it goes away. the button is on the control bar.

That's the audio engine, Does it go away when you disable it? 

First, use headphones to trouble shoot to rule out bad connections elsewhere. 
Start from the beginning , Computer off. 
Listen to the Octa capture from the headphone jack. You probably will hear nothing there with the computer turned off. 
Turn on the computer and play a song with Windows Media or Win Amp. 
Open another DAW and listen. 
Then open Sonar. 

I had this exact problem with a M Audio Fast Track Pro. 
It was in the A/D converters or something. 
So I ended up using the SPDIF and it was dead quiet. 

go into windows device manager and disable built in sound card and any aftermarket video card if you installed one. report back. might have been automatic update in background.

Make sure you are not getting some sort of internal feedback loop from internal monitoring capabilities on your sound card.

I was getting a similar problem occasionally and when I turned off the monitoring on my Dakota card, it stopped.

Mod bob, i'll check that out. Thanks.

It was in my situation. I traced it back to a day that I had used the Phantom Power option on the M Audio. I think it did something to the A/D converters. My sound was a hi frequency scream in the background,,, very low but there when you had silence in the room. It was also recorded to audio tracks. 

The only way you can prove otherwise is to try a different audio interface. I was lucky I had 2. The scream disappeared with the other interface. 

So I used it with SPDIF and my Yamaha 01v digital mixer and it was fine. So it was defiantly something in the analog circuits.  


We were typing same time again,

So how can you hear it with the octa capture off?? You must be using your on board. 

Also wireless devices can cause this sound. 

Arrgh, i'm pretty sure i turned off onboard sound...but if my octa is turned off it must be the onboard sound right? I have a wireless device but it's not installed. Just the card plugged in. I'm gonna check the onboard sound again.

I would run an AntiVirus and Malware scan immediately.

It could also be an alarm warning you that your CPU may be overheating or perhaps your SSD or an external drive that is failing. I would disconnect all external devices (USB, Firewire, thumb drives, etc.) and see if it still happens. Process of elimination. 

Dave,,, why on earth would running an anti virus scan solve this issue???? 

I read about a beep virus that makes your computer beep continuously. Check YouTube.

I would try enabling your soundcard again in the bios, there's no need for that unless your back in the xp days.
open sonar and go to drivers, select MME instead of asio, this will eliminate the Roland as your issue.
watch a few you tube vids or even try media player to listen to some tunes, still there???
disable wireless card I think cactus said that, its a good idea.

does sound like a demo software giving you the beeps.

how often are the interval's of the beeping ?

There is no interval of the beeping. It just starts when i open any sound related software.

A DAW on the internet? Bad Idea ... but thanks Dave for clearing that up, you usually have good tips but I thought this one was kinda weird. 

I still don't understand how you can hear it when you turn off your interface. That's the only thing you said so far that throws me off. 
The onboard soundcard is disabled in the bios! So that's disabled and the octa is turned off. Yet i still get the beep as soon as i load any software that uses sound.

So your saying this is a computer beep coming from the little CPU speaker?? 

No, not the cpu speaker. The monitors. Both of them. They pick up the noise with the sound cards turned off. As weird as it may sound i can guarantee you 100% that that is the case.
