Hello Bill
ls -l /proc/asound
shows the names of the cards.
On my system I get
dr-xr-xr-x 3 root root 0 21. Apr 10:56 card0
dr-xr-xr-x 4 root root 0 21. Apr 10:56 card1
dr-xr-xr-x 4 root root 0 21. Apr 10:56 card2
dr-xr-xr-x 3 root root 0 21. Apr 10:56 card3
-r--r--r-- 1 root root 0 21. Apr 10:56 cards
-r--r--r-- 1 root root 0 21. Apr 10:56 devices

lrwxrwxrwx 1 root root 5 21. Apr 10:56 SB -> card2
dr-xr-xr-x 2 root root 0 21. Apr 10:56 seq
-r--r--r-- 1 root root 0 21. Apr 10:56 timers
lrwxrwxrwx 1 root root 5 21. Apr 10:56 V10 -> card0
-r--r--r-- 1 root root 0 21. Apr 10:56 version
V10 for instance is the funcube dongle.
As the sequence of cards differs on different boots, I put
pcm.V10_card {
type hw
card V10
}
ctl.V10_card {
type hw
card V10
}
pcm.FCD {
type plug
slave.pcm V10_card
}
into the .asoundrc file in my home directory.
Now I can adress the funcube dongle by using FCD as device name in the
fcd block or in an audio source.

Hello Group;
I am trying to use an external USB Audio DAC.
According to the documentation in the audio source block, if I leave the
device name
blank, the block will use the default alsa audio device.
My question is, how do I find out what the name of the USB device is ??
Typing lsusb -v produced the following:
Bus 002 Device 004: ID 041e:3042 Creative Technology, Ltd
Device Descriptor:
bLength 18
bDescriptorType 1
bcdUSB 1.10
bDeviceClass 0 (Defined at Interface level)
bDeviceSubClass 0
bDeviceProtocol 0
bMaxPacketSize0 64
idVendor 0x041e Creative Technology, Ltd
idProduct 0x3042
bcdDevice 1.00
iManufacturer 1 Creative Technology
iProduct 2 SB X-Fi Surround 5.1
iSerial 0
bNumConfigurations 1
----- snip ------
Can anybody help here ??
Thanks;
Bill
