Hi, I cannot use my 0404 USB card any more since the upgrade to F10 too.

I applied the patch to the Fedora pulseaudio 0.9.13 package which 
already had 24 patches applied. It looks like you're the maintainer too, 
so I hope no problems with that. The patch applied cleanly and compiled 
too, but I get this when starting pulseaudio:

pulseaudio[2347]: alsa-util.c: Failed to set hardware parameters on 
plug:hw:1: No such file or directory
pulseaudio[2347]: module.c: Failed to load  module "module-alsa-source" 
(argument: "device_id=1 
tsched=1"): initialization failed.

pavucontrol doesn't show the E-MU 0404 USB card, only the built in 
nvidia chip.

So I'm forced to use the on board nvidia chip which really sucks. Noise 
gets on the channel when there's any hard drive activity etc.
