@vulejov: I'm really sorry but I cannot help you here! I'm only able to source drivers for this board:

I found them!
Not exactly easy, look for them on Google like WeiLiangHiFi_XMOS

WaveIO still works
 
While doing some experimentations with cleaning up windows services and making a lean mean machine I disabled Windows Audio service and Windows Audio Endpoint Builder service. Guess what? Audio through WaveIO still works. I am running JRiver Center 18 on a dedicated Windows 7 based PC.

I cannot tell the difference in audio quality as to me it seems same with or without audio services disabled.

Lorien and other members! what are your opinions on this matter?

The WaveIO/Xmos driver does not need the Windows audio services. On my system, they are disabled.

Thank you, Lucian
 
You built my WaveIO several years ago. It has performed flawlessly ever since. I still smile every time I look at it!

I particularly appreciate that it is able to output the audio stream simultaneously so more than one DAC can be driven. This facilitates A/B comparisons.

I gave this a try yesterday, disabled Windows audio & Windows audio end point services. I'm using foobar2000 v1.3.1. . To me the difference was audibly better, much more relaxed and detailed. Windows seems to alter the bitstream for worse.

I'd now like to use this permanently but none of my other application seem to be able to make direct use of the WaveIO driver.

@Lorien, any suggestions on how to make the WaveIO driver directly accessible for applications like VLC and a webbrower etc..?

I don't recall the syntax off hand but you can easily write a batch file to turn a service on or off.

To start a service:
Net start name_of_service
To stop a service:
Net stop name_of_service

I was just thinking the same thing. :cool:

I wrote some batch files to help me optimise windows 7 if they are of any interest:

I now use windows server 2012 as it sounds better - strange but true...

Wow - that's a fine piece of work and very generous of you to share it with us.

Was a bit confused in that your post says that it was written for optimising Windows 7, but the batch file itself looks like you were optimising Windows 8?

Like you, I use Windows Server 2012 R2 (audio stack is the same as in Windows 8.1) and it is clearly the best Windows OS for audio yet.

Would your batch files be dangerous/inapplicable/not optimised for WS2012R2? Or are you developing the same strategy for optimising WS2012R2?

Thanks again

Jonathan

Any idea why Server 2012 or Windows 8.1 would sound better? Is this also the case when you disable Windows audio services and only use a WASAPI/ASIO driver?
