Just purchased the XENYX502 USB Mixer. I am using Windows 10. Audacity 2.3.3 and settings are on the USB Audio CODEC for both mic and phones. I am not able to record. I have read about this situation and have gone through the protocals recommended to resolve. Alas, these have not faired well. Any solutions? If not I will be returning my purchase. p.s. I have a USB mic that works fine in both Audacity and in Auditions. This mic is ran directly into my computer with out a mix box.
