Doesn't play Project with audio fx

Are you saying the FX aren't in the signal path?
Have you bypassed all FX? The letter E will bypass all FX. Also the button FX in the control bar will bypass all FX.
 
Or are you saying you are getting dropouts where audio stops?
Try increasing the Sample Buffer in Preferences > Driver Settings > Asio Panel...
If you are not using the ASIO driver style you should seriously consider it.

I don't know...bypassing FX i can play the project or export it....in another case, i can do nothing....

ops....it has not passed the test i think...
 
this is the message:
Your system seems to have difficulty handling real-time audio and other tasks. You may experience drop outs, clicks or pops due to buffer underruns. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. At least one detected problem appears to be network related. In case you are using a WLAN adapter, try disabling it to get better results. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.

thank you so much.....i will try all your suggestions.....and i will come back for any problem....
 
Thanks again!!

Gosh - looks like my laptop, it has a Core i3 in it; the ndis, i8042prt (ps/2 driver), and Intel AHCI (SATA) driver all go boom. DPC looks good most of the time, it's the interrupt to DPC start time that seems to be the issue.
 
There's certainly a lot for me to look into, but I'm not in a rush. I normally work on my desktop. I plan on using the laptop for tracking, where I can used a bounced rhythm mix as a backdrop for recording vocals, which will keep processing to a minimum. My Motu interface has a built in mixer with monitor FX, another great help.
Once done, I copy the recorded tracks back into desktop project. Will be using Gobbler to stash things in the cloud.

...or i should buy a mac book pro :-)

I will try all these solution ti check the results...

If it does not work, i will install again the operating system...

Thanks!

Ok, i will follow your suggestion. Thanks again...

Vagabondaggio,
 
One possible cause...
This can happen if your computer is scanning those new WAV files for viruses. After you finish your recording, the computer virus scanner will automatically start hunting for viruses in the new files. This uses a lot of resources on your computer while it is scanning.
 
If you leave your computer on for an hour and then hit play, does it play smoothly?
 
If so, you should suspect the virus scanner and disable it.

Windows has it's own virus scanner in Windows 7+8. Hit the start button and type Virus Scan and you should find it. Turn that off.
 
If you have a laptop, try...
-- disable the batter in device manger (make sure you're plugged in first)
-- disable the video driver (these have power saving features)
-- disable the WIFI card
 
To do this, right click on My Computer and choose manage. Select Device Manager and then find these things within the device manger.
 

What are your settings for saving your audio? Have you checked save audio in the same folder?
Im just guessing here a little.
