I reccomend to not even bother installing the suplied asio drivers by samson! RAID1 Intel Rapid Storage. Multi-processor or multi-core intel or amd-based pc with 2 gb ram running windows 7 or later. Samson has provided instructions for adjusting the volume level of your c01u in windows here. To use of windows pc with standard usb condenser microphone. Install the samson c01u works like camtasia studio. Not all audio devices are compatible with it, but most are. These problems could also be the result of improper configuration or incompatible hardware. I have a usb mic samson co1u and an audio interface focusrite scarlett 2i2 with designated asio. I'm running an acer aspire 7535 notebook, windows vista, sonar 6 producer edition, and the samson c01u usb condenser microphone.
