## Questions & Answers

**Q: Is it compatible with Window 11?**
A: Yes, It's compatible with W11. If you are going to work with RaspBerry it's not 100% compatible.

**Q: HH, can I ask what brands you purchased that were good?  Thank you.**
A: Like I said, I have been unable to find another usb audio device that supports stereo microphone inputs. I have never had any issue with any usb audio device except this one, in terms of the hardware being such low quality. There's a lot of  usb dacs that are not too expensive. Depends on what you need.

**Q: What is the difference between c1-1021450-1 model usb-sa-1 and usb-ma p-c1-1024200-1? should i prefer one over the other for use with dragon**
A: The c1-1021450-1 usb-sa-1 (which I bought) has a short cable between the USB plug, and the part of the device with the audio mic/speaker jacks. I believe this design puts less pressure on the laptop's USB jack, and lets the audio cables go off in a different direction more easily. The other model, as far as I can tell, does not have that cable or that flexibility.

**Q: Is this compatible with Windows 10?**
A: It works, but it stops after a bit and you need to unplug it and plug it back in, making it not reliable. I purchased this one and I havent had any issues with windows 10 and its cheaper.

Drivers have problems with Windows 10. They very rarely change sample rate when in use causing pitch to drop. Otherwise this would be a 5 star review.
