Ok, I’m having the same issue except with a Windows 7 PC. Running Audacity 2.1.2. PyleAudio PT659DU using the USB connection. I do not get an option for 2 Channel. Has anyone mentioned whether switching to a RCA to 3.5 mm cable, instead of the USB cable, solve this issue?
Weird… I’m going to guess it’s a driver problem. You might try updating the drivers, but it should already be using the regular Microsoft supplied drivers so there shouldn’t be anything tricky about it…
Just ordered a RCA to 3.5 mm cable and will let everyone know.
Does your computer have line-in? If you want the best quality, you can’t use mic-in, even if mic-in is stereo.
Normally, if you don’t have line-in, the solution is a USB audio interface with line-in. …But, you’d probably have the same problem as the Pyle’s USB connection.
