Thank you Uber,
Ya, tried everything you suggested and much more. BUT, I FINALLY got my speakers working again. I'll just post my thoughts that I posted on facebook here:
VERY happy man here. FINALLY got my external speakers to work!!! So, I did a reinstall of the OS. What I suspect the problem was is when I first bought the computer, it had an older version of WINDOWS built in like 10.2.3.4 for example and that version worked well with my speaker drivers but when the computer broke I suspect they reinstalled with a newer 2016 version of WIN 10 like 10.9.8.9 that the older updated speaker drivers no longer were supported by. So in the factory, they probably used a latest disk for their install and by me going back to the built in WIN 10, I basically reinstated the computer to an older build of the system which the drivers for my speakers supported. Regardless, I am happy to have my speakers back.
It makes total sense and I hope that Line 6 will find the time to continue to support their update drivers for new versions of windows as we journey to the WIN 11 and 12 and 13 series. :) So we can all enjoy our toneports that we've come to know and love and rely on over the last 10 years or so. Awesome product guys...hands down and kudos for the excellence in reliabilty and customer service I have recieved over the years being a pain in your asses over all the issues whether big or small. The line 6 crew rocks! The community here is great also.
What can I say...PROBLEM SOLVED!!! *CLOSED*
