Back
here, I had been having trouble with my E-MU 0404 USB audio box whenever I tried it with any of three different laptops under Windows. At that time, Linux wasn't even an option, as the drivers either didn't work at all or maxed out at 16/48. My workaround has been to just use it as an analog preamp to my LS-10 (which works very nicely).
Well, I decided to give Fedora 12 a try, and, surprise! All sampling rates are available, at 16- and 24-bit depths. I installed a copy on my Acer Aspire One netbook and recorded some 24/96 line-in "footage" played by a different system.
As long as I don't use any networking, both record and playback work without any clicks, pops, or other extraneous noises. This same netbook using XP was a lost cause for recording, no matter how many devices I disabled.
A desktop system with Fedora 12 exhibited none of the networking-related problems... just as my XP desktop worked flawlessly with the 0404. At any rate, if I'm going to be taping with a laptop, network access is about the last thing I'd be concerned with.
