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
