Dropouts in Windows

[Tobiah]

After reinstalling Windows 7 I'm getting heavy dropouts in my audio.
With the old install, I could run at 24/96 down to 5ms latency.
What's odd, is that increasing the ASIO buffer size doesn't help
much. I run DPCLatency checker, and it stays well below 500 micro
seconds (stays in the green).

All of the hardware is the same, so I'm looking for suggestions.
I am also looking for a guide to tuning Windows for low latency.
All I've done so far is to go through the performance settings
and turn off most of the visual effects.

I'm using an M-audio fast track ultra (USB device).

Thanks for any help.

An audio latency checker is a start

Are you using ASIO? CHeck how big the buffer is -0 it may need
lengthening a little.

There is an entire discipline devoted to this. I believe I made the
mistake of updating Windows 7 and began to have mild problems.

I use LatencyMon to check what's what.

It's never happy. It reports "Highest interrupt to process latency" of
5 msec - yuck.

but if I turn off the Ethernet port, I don't get dropouts. I haven't
gotten to where i know if I need more RAM or what.

LatencyMon will identify which drivers are causing problems.

Not to be rude, but I covered all these points in my
message that you didn't read :)

I was rushing past the computer when I posted. Sorry

For 1., make sure power profile is set to Max!
For 2., if on ATI/ AMD switchable graphics, set it to Power Saving GPU.

1. can solve all the jammed audio.
2. can solve graphic interface irresponsivness with some plug ins.

How about if you disable ip v6?

Kind regards

I'd drop Win 7 like a bad habit.

Anyway, lots of info on Win 7 audio problems...

I use Windows 7.

Aside from tuning performance and power settings, I disable the wifi
card in Device Manager, and then I run msconfig, click the services tab,
check the hide all Microsoft Services radio button, and disable every
remaining service.

That seems to help. Thanks, Peter.


The tcp driver is the culprit that disabling the Ethernet port fixes.

Replace it with the thc driver. Much better.

Not to mention that the audio is way more fragrant, too. ;)

Across a variety of laptops, the most I've ever had to do was disable
wifi (not just switch off) and anti-virus and fiddle with acpi power
settings.

There was a machine, however, that had a problem because the usb system
was frequently sending commands to reset itself. I ended up looking at
this using Microsoft's free xPerf and Perfmon tools. That turned out to
be the ATI mainboard chipset drivers.

Not sure which setting did it, but I'm back to running
hundreds of simultaneous voices through Kontakt
at 24/96 with a 128 sample ASIO buffer. Reaper calls that
a 2.8ms latency with which I think I can live. I did
have the Min CPU speed at 5%, which was default. I also
unhid the high performance power profile which I hadn't
seen before.

Yay.
