Как вариант, может попытаться проделать следующее:

Some people think that better than ASIO is to un-map the USB DAC device from the KMIXER. This is done as follows:

Go Control Panel => Sounds and Audio Device => Select Hardware Tab => Select USB Audio Device.

Click Properties Button => Select Properties Tab => Click the “+” to the left of [+] Audio Devices that will pop down USB Audio Devices.
Select USB Audio Devices and click Properties.

Check both Use audio features of this device and Do not map through this device.
==> [ Apply ] <==

That will map through the KMIXER without using ASIO.

или это (что тоже самое в принципе):

With some USB audio devices I was told to do this:

Number One for XP is un-mapping the USBTD from XP and the dreaded Kmixer.
Go Control Panel =>
Sound and Audio Device =>
Select Hardware Tab =>
Select USB Audio
Device =>
Click Properties Button =>
Select Properties Tab =>
Select the audio device =>
select "Use audio features of this device" and "Do not map through this device".

In Foobar2K you need to select the output device “USB Audio
Dac/Device” and work through the myriad of choices.
