Hi Susan, I have a layla20.  I found that the firmware was missing  
from ALSA in Ubuntu Studio Feisty with some other things.  This was  
fixed by downloading the latest ALSA and rebuilding.

	This would include:
	Alsa-drivers
	Alsa-firmware
	Alsa-libs
	Alsa-utils

	Extract each of the above to separate directories and then enter  
alsa drivers for example and begin there with ./configure, make, make  
install - to install each portion of ALSA.

	When installing ALSA drivers, include the sound card as follows:
	$sudo ./configure --with-card=layla20

	This makes sure to compile the driver for your soundcard which may  
be different than 'layla20', also note that the card name is  
'layla20' and not 'snd-layla20'.  You can put multiple cards on that  
line seperated by commas.  For example ./configure --with- 
card=layla20,usb-audio

	After the install try modprobing the layla20 driver:
	$modprobe snd-layla20

	If you get no response to the command it is probably working.

	Try the aplay -l command to list playback devices and see if the  
card is there.

	Edit /etc/modprobe.d/alsa-base   and set the index of the layla20 to  
0.  This makes it the default device for the system.  You can see  
various other lines in there with =1 etc.  Here, refer to your device  
as 'snd-layla20' for example.  Then reboot.

	If your echoaudio card has spdif, remember that to access this you  
should use hw:0,1 in various software and dialogs to specify the  
digital device on the soundcard.  For example in qjackctl.  hw(0,0)  
would be the analog devices.

	Ubuntu Studio also comes with a nice app called echomixer that can  
be run from a terminal.

Hope this Helps,
