I've tried looking for updated BT600 drivers, but I can't seem to locate anything. The BT600 driver appears to be issued by Microsoft, with version 10.0.22000.1. I have also had a poke around in Plantronics Hub but can't seem to see anything related to audio quality.

I expect Intel will give me the run around and say contact the computer manufacturer though it really is an Intel issue with how Intel has developed the Smart Sound Technology software. The computer manufacturer has to live with Intel design choices.

I am with a company that has developed sensor products that use the USB Class 1 audio protocol. The products return vibration data instead of audio data but show up a USB microphones as far as Windows is concerned. I have to try to provide support to customers of our products to try to get them to work. So this issue will occur across all computer manufacturers.

Unfortunately, some computers have added Smart Sound Technology for USB Audio that inserts itself in front of the standard microsoft audio drivers that work well with our device. The first symptom is apparently disabling support for 24 bit audio. Second symptom is not working with the Windows kernel streaming audio interface causing application to fail.

The Intel SST driver is wrapped by the audio codec driver and then provided to the OEM, therefore, there is no support from Intel Customer Support. To find out if Intel SST can be disabled in your USB device, our best recommendation is to contact the OEM for further assistance.

Unfortunately, it is not possible to disable Smart Sound Technology for a specific USB audio device. Smart Sound Technology is a system-level feature that is designed to improve the audio quality of devices that support it. Disabling it would affect all devices that use it, not just your USB audio device.

However, you may be able to work around the issue by using a different audio interface for your sensor products. You could try using an external audio interface that does not rely on Smart Sound Technology, or a different USB port on your computer that does not have Smart Sound Technology enabled.
