Author Topic: Upgraded PC to 64 bit, now Spark maxing out CPU & getting audio dropouts  (Read 938 times)

I was running Spark through Ableton Live 8 on a Windows XP 32 bit machine with 4 gig ram and 4 core AMD Athlon CPU, and whilst it was a little CPU hungry, it worked fine.

I've just upgraded to Windows 7 64 bit, 8 gig ram and 6 core AMD Phenom CPU and the CPU Load meter in Ableton is freaking out, jumping up and down to 80%, even when nothing is playing!

When I play the project there are massive audio dropouts and the playback slows down. As soon as I delete the track containing Spark, Ableton settles down again.

So I tried running it in standalone mode, and still got audio dropouts. The major change here is Windows 7 64bit environment. Spark doesn't seem to cope with it at all.

Tried the upgrade to 1.1.2 and no change. Anyone else experience this...?

I have Windows 7 64 bit installed on my computer and don't have such problem.
Can you give me details about your setup (audio driver, sample rate, buffer size ..)?

Thanks.
2 questions:
Did you use the same audio card with your previous computer?
Can you try with the built in audio card?

Yes, used the exact same Nio on the previous setup. All I did was update the drivers. Tried using the built in audio and seems slightly better in standalone mode, but inside Ableton still the same issues - very high jumping CPU meter and constant audio clicks / dropouts.

Further update to this issue.

I have just installed Windows XP again on my system as a dual boot setup and reinstalled all the audio software and Ableton. Now everything runs fine just as it did before the Win7 upgrade.

In addition, I have noticed the same audio issues inside Ableton in Win7 in projects where I'm not using Spark, so clearly this issue is not specifically related to Spark, it's a more general audio issue that I'm having inside my Win7 64 bit setup.

Ableton tech support have been unable to diagnose the issue so far. Kevin - can you suggest any resources I could consult for troubleshooting audio issues in Win7?

First of all, I would try to make it work with the built in audio card.
If you achieve to this, I think you can contact Novation support. :)
