Audio drop out

HScadden wrote on 12/9/2011, 7:41 AM
I am having a problem both with Vegas Pro 11 and Sound Forge 10 after I upgraded my machine from Windows XP SP3 to Windows 7 so I could use the new version of Vegas.

When I am playing back audio, no matter how huge I set the buffers on my audio card (4096 max), I will get audio drop outs or the stream gets totally dorked up if I do something like zoom the timeline or move my mouse a lot.

I have had the audio stream go out of sync until I hit pause or stop and then start again. At this time the audio goes back to normal.

I am using M-Audio Delta 44 cards which have never given me a problem in the past and my video card is a NVidia GTX 560 Ti.

Like I said, when I was using everything on XP life was good, now the new Windows is killing me!

I have tried disabling drivers etc.. to see if it would clear up and still no luck. If I run a latency checking program I can see the latency jump way high as soon as the audio issues start in either Sound Forge or Vegas.

Appreciate any suggestions.

"my machine"

What "machine"? System specs?
Media properties? Project properties?
What's on the timeline? Effects, generated media?
Are media settings matched in the project?

I am running a dual core 3.2 GHz machine with 2 Megs of ram. The file in question is just a plain old wav file of 44.1 at 16 bit nothing special at all.

Like I said, I NEVER had this problem with Windows XP and Vegas Pro 10 or Sound Forge 10 until I upgraded to Windows 7 and Vegas Pro 11.

In my mind, it is something ... more than likely a driver or Windows setting ... that is haunting me. I have been using these products for many many years now so it is not like I am fresh out of the oven. I just want to know if anyone else is having this issue and if they have, what were problems for their scenario.

When I am viewing say something like an HD video off of Youtube, I have NO problems at all ... only when I use Vegas or Sound Forge.

Have you upgraded your audio drivers to the latest for your OS?
HScadden wrote on 12/9/2011, 11:19 AM
Yes, as soon as I did the upgrade (using the Upgrade version of Windows 7) from XP to 7 Pro, I had no choice but to re-installed every blasted thing on the machine. I rounded up all the latest versions for all of my drivers video and audio.

I have been running video games with no issues at all ... running video or audio files from Youtube/Myspace/Facebook etc.. no issues at all.

I am just getting more and more perplexed. The only weird thing (as strange as it seems) might pertain to my wireless mouse and keyboard.

As a last ditch I am going to put a regular keyboard and mouse via the PS2 ports on the machine to see what effect that might have.

I was listening to an audio file that I had rendered in Vegas last night using Sound Forge while I was replying to someone on Facebook. As I was typing the reply to the message, the audio stream started getting weird on me. I am not a slow typer but I can't understand while their would be in USB issues with however fast I am typing on however fast I am slewing the mouse. I am not Superman!

As I stated earlier, I was running a latency checking program and doing crazy stuff with the mouse / keyboard had no effect until audio from one of those two programs was playing, then it was open season.

There is nothing about a vanilla WAV file that should make it stutter on even a dual core machine.

One last thought -- Win XP only accepts 2 GB of RAM. Win 7 accepts (and needs) more. So increasing to 4 or 6 GB would be the next thing I would try.

In Vegas' audio preferences, turn off track buffering.

Are you using. ASIO , Wave classic, or mapper?

What is buffer setting for audio?

This is possibly like what I get on my system #2 ever since V10 and updating XP to SP3, especially when opening FX chains (the animated 'fly-out' maybe does it). Now W7/64 and V11, same problem. .

Even with just a single mono 44k1/24 event.

Been harping on about it on for years on various V forums, but never solved.

As you may recall I've done all the buffer-size/drivers/track-buffering/etc/etc things suggested, to no avail.

Which is a bugger cos it's my main studio audio PC !

Well I have 4 gigs in a Windows 7 32 Bit machine and I STILL have the blasted audio problem.

I have swapped / disabled / updated until the cows came home and I was better off staying with XP SP3 and Vegas 10. Wow, this has been a fun upgrade experience.

@HScadden

So turning off track buffering did not help?

I have played with the track buffering, buffer size for the Delta-44 control panel etc..

The one weird thing is when I launch Sound Forge 10, no matter what I do, it will not load with my requested audio channel. It is always saying that the channels that I want on my M-Audio card ... that it is in use by some other application. I HAVE NO OTHER apps running with the exception of what Windows' itself spawns running. No matter how many times I change it to what I want and then restart the program, same crap different startup.

When I launch Vegas Pro 11, it has absolutely no problem with whatever channels I select for output etc.

The only reason I upgraded to Windows 7 was because of the Vegas Pro 11 requirements ... that and Vegas Pro 10 would not accept my video card for Cuda cores until I switched to 11.

The other strange and annoying thing seems to be with how Windows wants to setup my sound. If I have a project up in Vegas / Sound Forge and it is 44.1 blasted Windows will try to play it as 48 KHz instead. Is it just me or did Microsoft release another virus that they called a Windows verison!

Larry, I have been using that latency checker, that is how I saw the weirdo stuff going on with only Sound Forge or Vegas and the mouse actions that I have described in my initial post.

If you open a track FX chain window, can you see a big jump on DPC, and can you actually see the pop-out animation occurring. I can, and it appears to be generated withing V, ie not a Win animation. I allso get glitches when I move/or resize windows.

I suspect this is related to something within the DOT.NET environment, as this started for me immediately on a Win update (XP SP1 to SP3) and hasn't go away since, despite completely new hardware ; i7-2600, W764u, 16GB. So the hardware sure ain't running out of steam !

OK, DPC Latency Checker tops out at 267us - about a quarter of what it says will compromise audio playback. This is during playback zooming windows and popping (gives a new meaning to the term) up FX windows, and opening Master FX during playback.

Currently my only problem is the FX window thing, though at various stages zooming windows, and dragging windows from one monitor to the other has given the gap. Matrox, AT, and NVidia display adaptors, both MOTU pci and pci-e adaptors with 24i and HD192 interfaces, and also with TB Fiji .

Haven't tried my Turtle Beach Pinnacle, as my new mobo has no ISA slots and the Hallsound drivers don't work on W7, eh Peter ;-)

So the problem is presumably not related to latency (or cpu peaks) on device drivers....

Whatever they fixed in the latest Vegas Pro 11 update seemed to take care of the issue ... at least with Vegas. Sound Forge is still having the problem as I stated in the beginning.

I didn't see anything on the release notes that looked like there was a real time audio fix of any kind.
