Fast Track Ultra - Sound glitch at 96Khz in Windows 8

[Readysound]

I'm running the latest version drivers (6.1.9) for my Fast Track Ultra, in Windows 8 64bit

I notice that when I set the device to 96Khz and then play sound in Windows (via any media player) it's fine for a fixed period of time (around 9 seconds) then the sound becomes garbled / corrupted. If I stop / pause, then play, the same thing... 9 seconds fine, then it's a mess. This happens regardless of the buffer size.

If I knock it down to anything less than 96Khz, it's fine.

Strangely, If I engage the sound card via ASIO (from Reaper for example), even if set to 96Khz, it plays fine.

Has anyone come across this or know a solution? Or is this being worked on for a next driver release?

Many thanks!

Check your Playback Devices in windows' sound control panel. Are you able to set it to 96 kHz from there?

Windows can be picky about sample rates and bit depths for system sounds (and media players). In these cases, you're using WDM and not ASIO, which could explain why running Reaper in the background makes the problem disappear.

That's what I thought, with Windows handling it differently (via MS Sound mapper etc)... I checked the sample rates under Sound setting via Control Panel - 2 Channel, 96Khz as expected. Still got the problem.

Anyone else experiencing this?

Yep, having the exact same issue here. I've tried absolutely everything imaginable (being relatively experienced in these matters) over the past week, yet nothing seems to enable my system to stream reliably at 96KHz. Fine at 88.2KHz, although it's a minor pain to have to switch down when I want to use a media player/youtube/game etc.

The problem appears to be related to the USBPORT.sys driver that windows uses to control all USB hubs.

Update: Scrap that - it's not happy at 88.2KHz either.

To me this seems like a driver problem, so I booted up your thread hopefully someone from CS will chime in.

I may have found a hackish solution to this problem. Early days, so will not post method until I've tested extensively. At the very least I'm presently listening to Them Crooked Vultures upsampled to 96KHz without any glitches.

Thanks Emcha!

Hi,

I can confirm the issue.
I'm experiencing exactly the same symptoms @ 96KHz.
Driver version 6.1.9, Windows 7 64bit.

Any news on this?
Cheers

No news here. I've reverted back to 6.0.8 which works fine, except it means you have to turn off fast boot in Windows 8. From what I recall, 6.0.8 worked flawlessly in Windows 7.

Emcha, is there any way of escalating this to support staff?
