Input from External Microphone Not Coming Through in Sterio

First things first. I’m running Windows 8.1 on a Dell Inspiron 15 3000 series and have Audacity 2.0.5.

I only just bought a new computer with Windows 8.1 on it. (SO not impressed with this OS.) Anyway, I’m trying to get everything set up. I do voice recordings using an external microphone I use through a Tascam US-200 audio interface. It has the ability to record in stereo and I have done so using Audacity on my old computer running Windows 7 with no problems.

I checked that the Tascam system has been tested with Windows 8. No problems there. I installed the drivers, got the newest Audacity I could find and set everything up. However, I’m still only getting mono sound instead of stereo when I attempt to record. I’ve double checked that the Default Format for the input device is set to 2 channel, 16 bit, 441000 Hz and that Audacity is set to take in a stereo input. No joy. I can record sound but only in mono.

What’s really odd is that when I turn off Audacity and turn it back on and then set the input to monitor the microphone I DO get stereo showing up on the monitor… for about naught point nothing seconds. Then it goes back to mono.

Any ideas?

Make and model number of the microphone?

What happens when you set Audacity to record in stereo in Device Toolbar ? Do you get just the left channel recording?

As I understand it the US-200 has two XLR/TRS inputs and the first input is the left channel and the second input is right channel. That’s how those type of interfaces usually work. So if you are only plugging in one mic, how did you get (real) stereo before?
