Thanks intel_jassowski and mmi - you guys rock! For some reason everything worked perfectly this time around. I already had another Edison board running 3.10.17-poky-edison+ so I did what you guys mentioned (again) and lo-and-behold, I have audio on Ubilinux!
I'm working with is alsa-based stuff, so I''m not using other sound systems like pulse-audio, etc. The input and output devices (Snowball USB Mic & Soundblaster Play 2! USB sound card) show up and work well - consistently.
Thanks again guys. And intel_jassowski, I like your pun - I needed a little humor in my day!
Regards,
Jeff
