Ok, thanks.

What soundcard do I need?

**What soundcard do I need?**

I'm not in a position to tell you that, just that SB never worked stutter-free for me in SF, Vegas, or Cakewalk for that matter.

If you'll do a search on the forums, I think you'll find models by Echo and m-Audio get mentioned. Also, their are opinions that Firewire is preferable to USB, but again you'll have to draw your own opinions. Again, there is a wealth of discussion on these forums going back a few years.

What driver model are you using?

ASIO, Wave Classic, DirectSound, or Mapper?

What is your buffer setting?

Peter

We test against consumer cards like the Sounblaster, and I cannot say that it is a particularly bad card in regard of stuttering problems. Its technical specs are not the greatest, but it does function properly.

What specific model of the Sound Blaster are you using?

Depending on the model you use, the SB cards only run at 48 kHz internally. If your project is 44.1 khz and you are using the Wave Classic or Mapper mode in Vegas, this can cause a resample to occur in Windows. The ASIO driver will only permit 48 kHz project settings, but you are streaming audio in the native format of the hardware.

Thanks Peter,

I'm using SB Audigy, Vegas settings are:

Microsoft Sound Mapper
Playback buffer - 0.10
Trackbuffer - 0.25
Audio buffer - 4
Buffer size - MME
Priority - Highest

Project settings - 48khz

Try setting the number of audio buffers to 2.

You should try the ASIO drivers and see what results you get with them. ASIO will also permit you to use the track input monitoring features.

Peter

Sorry, but how do I select the ASIO driver?

options ->preferences -> audio device
change "audio device type" (top item) - you should see ASIO in the list

Thanks, I only have 3 choices: Microsoft Sound Mapper.....Direct Sound Surround Mapper....Windows Classic Wave Driver

Neither the SB Live nor the Audigy I had on other computers had ASIO drivers (there is a newer Audigy that might have them, and I don't know if there are updates for the original series). They all stuttered in SF/Sony apps and various versions of Cakewalk as soon as any DirectX pluguns were added, regardless of IRQ, buffers, thread priority, driver assignment -- that's why I scrapped them.

I apologize for the fact that my input on this is a bit "dated," and the OP is running a faster CPU that I had on either of those machines. Still, if I was considering an upgrade from one of those cards, it probably would not be to another SB.

I've done some testing and:

If I add an audio file to the timeline without any video tracks.....it plays fine.

When I add a video track to the timeline.....the stuttering begins.

If I drop video on the video track above the audio.....stuttering stops.

When the playhead reaches the end of the video and the audio continues on.....stuttering starts.

Does this sound like a soundcard issue?

OK, you got my curiosity going. I blew the dust off an old SB Live, plugged it into my XP machine, and it auto loaded the Windows Classic driver.

I placed empty video tracks both above and below a long .wav audio track in V8.0b , and sorry to say I was unable to reproduce your problem (the output did start to crackle a bit as I added plugins to the track).

That being said, one really old-fashioned piece of advice is to plug your SB into a different PCI slot and see if that has an effect. IRQ clashes aren't usually considered an issue in XP, since it treats them differently than older systems, yet it wouldn't hurt to try.

Wow, thanks for the effort. If we don't come up with anything else, I'll give that a try.

Thanks again!!!!

The Audigy always had Creative supplied ASIO drivers. There were are third party drivers for the Live card - The KX project.

Creative did release a fix very early on that directly address a stuttering and timing problem for the Audigy ASIO drivers.

The Audigy drivers are availble from the SoundBlaster Web site. Do a Google for SoundBlaster ASIO and this should turn of information on the KX Project.

Peter

I downloaded and installed KX drivers only to find out Audigy "SE" is not supported.

Sorry I didn't have the exact model before now.....I didn't now what model it was untill I dug the box out of the attic.....SB0570.

So I reinstalled with updated drivers from SB website.....still have the stuttering and no ASIO. I guess this model doesn't support ASIO.

asio4all could be worth a shot at ths point...

For those who have it - it's been updated 21st Jan 2008!!!

(asio4all could be worth a shot at ths point...)

Right on....seemed to have worked after some simple testing.

Thanks

ANd while you've still got the lid off your computer, maybe pick up a cheap Audiophile 2496 or something off ebay or wherever, and plug that in instead !


geoff

Amen.
