I have some good news/bad news (or at least weird news). My system has had this problem recording in stereo with Audacity for the past few months. I just recently decided to start trying to figure out what was happening and see if I could fix it but as noted here I was less than successful at any resolution. So for the most part I gave up and just decided to go with the alternate solution – redirecting the mixer output into the laptops microphone jack – not what I wanted but it worked.
NOW, today after doing absolutely nothing new, Audacity started recording in stereo. Go figure. I do not believe I did anything different. I did not change anything from the day before. But to be sure I check all cabling, routing, software settings, etc. Everything appears to be the same. BUT IT WORKS. Must be those nasty gremlins again.
So, I’m good for now. I thank you all for your time and consideration with my perplexing situation. Any problems in the future I’m sure I will be back.
Again – my sincere appreciation,
Steve K.
