Topic: Windows 7 audio stutter

I just installed Windows 7, all works fine apart from when I pause a track in something like foobar or VLC. If I "stop" the track everything is fine.

In the case of WDM (VLC) the sound stutters when paused with some latency and a hiss remans as ~-94dB in TotalMix for about 10 seconds before the levels fall back to -inf

The same problem exists with ASIO, minus the stuttering and latency.

Thanks

Re: Windows 7 audio stutter

Hi Matt,
Make sure your system is optimized for audio. Depending on your computer hardware you system will need some sort of tweaking to get best performance.

We would need to know more about your system to recommend anything more.
Thanks Chris

Re: Windows 7 audio stutter

Thanks but I've already read through that and always use an stripped OS anyway. I think there is any actual "issue" rather than it being performance based since my machine is a quadcore desktop.

Thanks

Re: Windows 7 audio stutter

Do you see the same phenomenon with other media players?
What does "latency" refer to in this case? Not sure about the stutter (what exactly is it like?), but the -94 dB thing seems as if the player were somehow keeping the output open (and applying some dither or Windows doing sample rate conversion) for a while and then muting it. Do you see the -94 in the second row of Totalmix? If yes, this would support my theory... If you say it happens with ASIO, does it refer to ASIO applications like Cubase or e.g the ASIO plugin in Foobar?
I would tend to agree that it is not a performance issue, though, even if Quadcore per se does not automatically spell good audio suitability...

Hi Matt,
We would need to know specifics about your computer hardware to know if there is a setup, compatibility or hardware issue.

Re: Windows 7 audio stutter

Thanks for the replies. The "latency" I am refering to in this case is that the sound continues to play after i have paused something for a second or two. The "stutter" comes straight after the "latency" and sounds like the volume oscillating between current volume and mute before settling at mute. The -94dB issue occurrs in VLC, Foobar which uses an ASIO plugin and Flash player so it seems to be everything? I havent tested it in cubase as I plan on keeping an XP partition for mixing and Win 7 for audiophile purposes. I have never had these problems in XP with Foobar and VLC running the same settings.

My setup consists of the ASIO and WDM channel pairs playing into two unused digital outs which are then internally looped back through totalmix and taken by Console modular Studio which puts them through DRC and Filters creating a 2.1 sound output on three analog out channels. Again I have used the setup working perfectly in XP for years but the problem exists even if I bypass all the VSTS and set the ASIO or WDM drivers to play directly to an analog out channel (simplest trial setup). This is for when I use it as a Media PC which I mostly am.

I have the 9632 card with AO4S analog expansion in a Quadcore machine with DDR 3 ram and a 5870 tri display card.

I don't know if it's at all related but on opening and closing any kind of video I also get brief black horizonal lines on my monitors which again I don't have in XP. All drivers are installed.

Thanks alot.

Re: Windows 7 audio stutter

Hi Matt,
That is odd with the 3 head display showing the black lines. I would test all this with just a single monitor to see if it is occurring.
I guessing from that model number that the video card is an ATI/AMD?
Are you using the latest drivers? Version 11.8 is the latest.
Are Foobar and VLC both running at the same time?
Are you dealing with surround sound?

Thanks Chris

Re: Windows 7 audio stutter

Yeah the card is an AMD/ATI card and yeah, I'm using the latest drivers for everything.
Foobar and VLC aren't running at the same time but it wouldn't matter if they were, i am able to layer ASIO and WDM fine in XP.
It's not really surround sound, just a stereo pair crossed over with a third sub channel all via vsts.
Just to add to the list, Totalmix keeps loosing it's settings working with the Audiorelay midi program although I know that was actually designed for Vista so maybe bugs are to be expected.

Attached is a screenshot of total mix a few seconds after pausing a track and no other sound playing. The sub channel also has the problem, it just isnt showing up due to attenuation and hf filtering for the amp. Here Foobar is playing into the SPDIF which is looped back and processed, outputted to the three analog outs.

Thanks for the support hope it's sorted soon.

Re: Windows 7 audio stutter

Hi Matt,
So Console is running as a effects processor for VLC, Flash, Foobar, etc?
Have you tested playback back of VLC or Foobar with out Console running or any Total Mix routing?
Have you tried testing a single monitor set up with the video driver disabled?
I've never used Console before. It hasn't need updated since 2008 so not sure if there are any possible issues with that.
WDM behaves very differently than it did under Windows XP and Vista so there may be issues with how your programs are behaving because of that.
I don't use either VLC or Foobar so not sure if different setting or if there are limitations under Windows 7.
I am suspicious of possible WDM issues like what Daniel touched upon in his earlier post.

Thanks Chris

Re: Windows 7 audio stutter

Thanks for the reply, I've been busy - sadly the problems haven't gone. Yeah, console is running as an effects host for all my sound exactly as it was in XP. I have tried VLC and Foobar using the primary sound driver (ie WDM) and the problems still persist.

What is really concerning to me is that I just downloaded a track of "digital silence" and playing it results in the -94dB meaning I have a vastly reduced SNR output at all times so it is absolutely detrimental that this is sorted, the hiss is very apparent when playing soft solo tracks at a moderate to high volume which I haven't tried until now.

Has anyone else reported this problem, this cannot be right, even if i did want any music software under win 7 I simply cannot now due to the nature of solo'ing and the affect on mixing from the hiss as I mentioned.

If it helps simply forget about console and all the extras for now as the problem is clearly at a low level with some sort of configuration.

Thanks

Re: Windows 7 audio stutter

Do you see the -94 when playing the silence track in an ASIO application (try Reaper)?

Re: Windows 7 audio stutter

Yeah I do, it's exactly the same with everything. I just checked the IRQ but it on it's own channel as it should be, however when I went to conflicts / sharing it shows this:

I don't have a usb audio device apart from a webcam that isnt installed and the AMD audio driver was installed with the graphics drivers.

Thanks

Re: Windows 7 audio stutter

anyone?

Re: Windows 7 audio stutter

No such problems here with foobar2000 1.1.8 on WinXP SP3 (HDSP 9632 with driver 3.26) ...

Re: Windows 7 audio stutter

Yeah, I've stated in most posts I have an identical setup working fine in XP too..
I guess I could try updating the XP drivers and seeing if the problem appears but I can't imagine it.
It would be great if any mod or the admin could continue to advise, if the system info paste is meaningful?

Re: Windows 7 audio stutter

bump, please, I really need help sorting this...

Re: Windows 7 audio stutter

You could also try to measure your PDC Latency on your computer. The gfx driver could very well destroy your audio, or any other device drivers:

http://www.thesycon.de/deu/latency_check.shtml

If you get high peaks in this program, there is a driver that could hold up your audio or is holding up your audio. I've had bad gfx driver problems once with a Nvidia GTX460 card in my older Asus P5K Deluxe mobo, which resulted in very bad Cubase ASIO performance. I solved my problem completely with an older ATI X1550 gfx card, where the gfx driver didn't make any PDC peaks appear. I also know, that wireless driver stuff can hurt audio bad.

Re: Windows 7 audio stutter

Thanks, I tried this before though, just tried it again and am averaging at around 100us with no peaks even when instigating the problem. I though I had it sorted when I went to check this the first time before finding it was ok as it does "sound" like this sort of issue.

Please could the mods/admin continue their great support.

Re: Windows 7 audio stutter

Hi matt,
I still need to know exactly what computer model this is or specifics on the Computer hardware.

What is the USB Audio Device listed in Post #13?

I would confirm that the 2 Media player programs and Windows media Player play back fine on their own individually without Console running. I would also reset your Total Mix routing back to factory defaults. This will remove any extra routing you have done.
Hold down the CTRL Key while clicking on Preset 1 in the Total Mix screen.
This will will make all the routing 1:1 so it will be like the Total Mix is not active.
Check each player this way.
You need to narrow down where the incompatibility is happening. There are allot of variables in your setup that can go wrong.

Thanks Chris

Re: Windows 7 audio stutter

Thanks for the reply, my hardware is as follows:


CPU: Q6600 @ 3.4Ghz
Graphics Card: ATI 5870
Motherboard: Gigabyte P35-DS3R
Ram: 2GB Supertalent DDR3
RME 9632 & AO4S Expansion
2x 500GB Sata Drives

The usb audio device was a webcam, I have unplugged it and it no longer appears but the problems remain.
I have tried different media players as before without console running and reset Totalmix but again the problems are still here.

Thanks
