Raymond - because I don't know how to :-) I have very little knowledge of
alsa.

From lsusb my device has a different USB dev number than the other Xonar U7
card
Bus 005 Device 011: ID 1043:85c1 iCreate Technologies Corp.
Also if I run cat /proc/asound/card3/usbid I see
1043:85c1

When this I first tried this card I suspected that the '.' in the alsa card
name was a problem. So one of the very first things I tried many months ago
was to add:
"USB Device 0x1043:0x85c1" 1   to  the USB-Audio.pcm.iec958_device section
of USB-Audio.conf
this does  not work.

I thought I was using the correct format because further down the
USB-Audio.pcm.iec958_device section of my USB-Audio.conf I see some cards
with 999 as their device to stop them being opened
"Scarlett 2i2 USB" 999
"Sennheiser USB headset" 999
"USB Device 0x46d:0x992" 999
}

So I tried again today and found this entry on the web
http://git.alsa-project.org/?p=alsa-lib.git;a=blob;f=src/conf/cards/USB-Audio.conf;hb=HEAD
where it has these lines in the USB-Audio.pcm.iec958_device section of
USB-Audio.conf
        "Sennheiser USB headset" 999
         "SWTOR Gaming Headset by Razer" 999
        "USB Device 0x46d_0x821" 999
         "USB Device 0x46d_0x992" 999
  }

i.e. using an underscore to separate vendor id and product id

So I try
"USB Device 0x1043_0x85c1" 1
and stiil it doesn't work

Can you tell me what the correct format is?
