Ahhh ... playing around trying to re-create the problem made me remember something. When I first got this laptop (3+ years) I was using Pro Tools 9 for recording. At that time I noticed this C400 was sensitive to which USB port it connected to. Hadn't used the C400 much since then until a few days ago, but all was good as I'd happened to connect it to one of the other USB ports.

Setting up at the gig I guess I plugged the C400 into that specific USB port that had previous problem with the C400. I did try changing this at the gig but it still didn't work. It appears that when it gets in this bind running some other audio program such as Audacity with the C400 connected to one of the other USP ports clears the problem and BIAB works fine.

I can now re-create this problem and solution here in the studio. So, it's not a BIAB problem but apparently something idiocentric with my set-up.

However, now that the headphone jack's become a problem on this laptop I've begun looking at new digital I/O units and Iprobably need to begin looking for a new laptop too. Any suggestions for digital I/O that works well with BIAB would be greatly appreciated.

Hope these posts have been somewhat entertaining -- if not terribly relevant.
