[LAU] USB sound card under FC6

Hi guys,

   Hope you'al can help me out here?

   I am working on a project that will use an external USB sound card under
Linux. After much effort, I have gotten the device to work completely under
Ubuntu. Which is where I really need it to work. Unfortunately, my
development system is running FC6 and during all my testing I have
mis configured my ALSA to the point that I can no longer record from the USB
input. Playback works fine on both.

   This is how I am testing the device:

     arecord - -D plughw:1,0 | aplay - -D plughw:1

which works on a standard Ubuntu installed system on the same hardware.
On the FC6 system all I get is 'dead air'.

/* ---------------------------------------------------- */

My output from the FC6 system is:

This from dmesg:
ohci_hcd 0000:00:13.1: auto-wakeup
usb 2-1: new full speed USB device using ohci_hcd and address 3
usb 2-1: configuration #1 chosen from 1 choice
input: USB Audio as /class/input/input4

[root]$ arecord --version

/* --------------------------------------------------- */

   I am certain that it is something I have done but unaware of what it is?
I am at a loss. Is there a way to return to the default sound setup?

   Any ideas suggestions?

   Thanks for your time.
