I downloaded a sonar cakewalk program to my computer but there is no sound. How do i fix this?

Download is different from Install. It does not look like you can purchase and download Cakewalk SONAR 7 Producer directly from Cakewalk. However, to install on a Mac, you either need BootCamp, or a virtual machine (VM) solution such as VMWare, Parallels, or VirtualBox, and a valid Windows 7 or 8 install.

System Requirements

This sounds like the software still thinks it isn't registered to you.

Do you have a registration button in the program interface?

If you have already registered the program or registration isn't required, try loading Sonar on another box and see if it's just a compability problem with your hardware.

call cakewalk, their product might not be compatible with 64bit OS. They might offer a patch or workaround. And you could also try running as admin in compatibility mode.

The stuttering is caused by excessive CPU usage, in other words: you have too little CPU power to play the file with the inserted synth smoothly. You could try inserting a different synth or play with the rendering-options of the synth (like disabling aliasing, etc.) or increase the audio buffer size (under audio options ?), but the only longterm solution is upgrading to a much faster computer.

Even when you find some tweak which lets you play the file (just) smoothly, adding another effect or synth is likely to cause it to stutter again, since your computer doesn't meet the official (!) minimal requirements for running Cakewalk Sonar 6, which is at least a Pentium 4 1.3GHz computer (and you have a 1.0GHz computer).

I would recommend upgrading your computer to something which at least meets the "recommend requirements" of Cakewalk Sonar 6, which is a Pentium 4 2.8GHz or newer (like any Intel Core 2 system), when you're serious about composing music.

try downloading cakewalk from mininova, you will find a folder named ADDICTION, you have the keygen there to give you a registration code that works

Sounds like what is called a latency problem. You need to go into the settings in Sonar and under audio, adjust the Latency to a higher number...I don't know sonar home studio, or I would tell you the exact area to go in the menu's to adjust latency..Hope this helps!

That's a latency issue it sounds like.
There's a slider under "Audio" .

Move it in increments towards "slow", test it as you go.
Leave it at the highest setting possible that doesn't crackle.

I've heard this so bad that it sounds like a gun going off.
It scares the Hell out of you when it happens !

did you check in control panel ? what sound cart you have?

I looked all over the Cakewalk website and could find no info pertaining to using sonar 4 with Vista, however I did find a link to e-mail there tech support it is free and they claim a 48 hour responce time here is the link http://www.cakewalk.com/Support/SONAR/SR4.asp

I woll tell you this I am running Vista and have found there are some programs that just wont work with Vista, this is not nessaseraly true for you but just be prepared in case they tell you to upgrade to version 7

Hope this helps
