AAARRGH! Is nothing ever easy??? Loud buzzing in Sonar

Okay, I did remember one other change I made, but I don't remember when I made it. I was running at 3ms ASIO latency, so I just now upped it to 4ms and I'm not getting the buzzing...yet.

*sigh* Maybe I will play some more string parts tonight after all. :)

Does it only happen with Dim pro in the project??. Does the buzz show up in the meters??

I don't know if it was showing up in the meters, which makes me think it was my sound card freaking out. lol Raising the ASIO latency to 4ms seems to have stopped it, but I don't really know if that had an actual effect on it. It was happening rather quickly before and hasn't happened since up bumped the latency up to 4ms. I can bump it back down to 3 and see if it happens again just for testing.

BTW, in case it's relevant, my sound card is an E-mu 0404 PCI with the latest drivers.

but I did notice my CPU spike while the buzzing was happening.

What else is running in your pc?
Click share drivers with other programs in sonars options menu.

Its not dim pro, if there is no meter movement. Its looks like a driver issue. Maybe uninstalling and reinstalling the emu drivers will do some good. Try WDM driver mode also and run the vst scanner again

Well, I still haven't had that buzzing problem. I even added a True Pianos sound for a layered piano+pad thing that sounds pretty neat. No buzzing and no other audio weirdness.

Thanks!

Yea, WDM is what EMU likes..

That's good to know! I always thought we were supposed to use ASIO if it was an option. I'll leave it at WDM.

Thanks again!

No, your suppose to try both and see what works bets. Ive used WDM for some cards and ASIO for others. Every card and every pc is different

Got it. For some reason, I was under the impression that ASIO was a superior technology. I don't really know anything about either of them, so I don't know where I got that impression. I bet I'll be a lot happier with this setup now.

Ugh...what the heck is wrong with my system?? I was using WDM last night with no problem. I installed Omnisphere tonight (very, very, very cool) and wanted to play around with it. I wasn't getting any audio at first in Sonar even though the meters were moving. I loaded up another project and hit play. At first there was no audio, but after a few seconds there was really nasty, distorted audio. It was really awful. The distortion was so bad I could barely tell what the song was. So, just for grins, I switched back to ASIO and all was well for a while.

I took a break to watch Heroes, then came back and launched Sonar. About a minute into playing something, the buzzing I had last night came back.

This is so annoying, I'm starting to wonder if my sound card is dying. I thought the E-mu 0404 PCI was a decent card, though. And I'm running the latest drivers.

EDIT: And now I've switched back to WDM and all seems to be well. WTH is up with my system??

*grrrr*

Come to think of it, these weird sound issues did not arise until after I did the loopback test with my card. I wonder if that somehow damaged something. I wasn't having any of these issues prior to that. I can't imagine why that would have done anything, but now I wonder if it did. I should completely power my PC down, unplug it from wall power, then restart it after a bit. Maybe something in the card is just freaked out.

Who knows? I certainly don't!

You're not by chance using 96K sample rate? Some have reported nasties with Dimension @ 96K.

Bill B.

Nope. I was using 48K with ASIO and 44.1 with WDM. For some reason, my card doesn't want to do 48K using WDM.

Does it happen when you are not using those VSTis?

Yeah that's where I'd start..

Try a basic project with no 3rd party Synths or FX and
then add them in 1 by 1 to see if you can find the culprit.

I just quickly listened to some different projects, some with VSTis, some without. I didn't hear a single glitch. I'm beginning to wonder if there is a heat component to this. I usually leave my PC on all the time, but I shut it off last night as a test. I wonder if some component on the E-mu 0404 is overheating.

I suppose that's one possibility. But I didn't have any of these issues until I did the loopback test. I can't imagine why that would have had any effect at all, but that was when the problems started. All I did was connect one of the outputs to one of my inputs, as the instructions say, and ran the loopback test. Ever since then I've been having these issues. I wonder if there was some sort of static discharge when I was swapping cables around.

Hmm.... I don't know. It was acting just fine prior to the loopback test, so maybe it's not a heat issue. I definitely don't have cooling issues in my case, but that card is next to a high-end graphics card that gets pretty hot. That might marginally increase the temp around the sound card.
