I've just been writing about this topic in the Campcaster manual:
http://en.flossmanuals.net/Campcaster/ConfiguringSoundcards
Each device of ALSA hardware has a card number *and* a device number.
The first hardware card in the system is given the name:
hw:0
Each item of audio hardware can sometimes have multiple devices, also
numbered from zero upwards. The card number and device number are
separated by a comma. Often, there's only one device per card, so the
first card and the first device on that card is referred to as:
hw:0,0
Some audio interfaces have both analogue outputs (line level) and
digital audio outputs (such as S/PDIF), on the same card. To check which
device has which number, we can use the aplay command:
$ aplay -l
The terminal might display something like:
**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: AD198x Analog [AD198x Analog]
Subdevices: 1/1 Subdevice #0: subdevice #0
card 0: Intel [HDA Intel], device 1: AD198x Digital [AD198x Digital]
Subdevices: 1/1 Subdevice #0: subdevice #0
card 1: Aureon51MkII [Aureon5.1MkII], device 0: USB Audio [USB Audio]
Subdevices: 1/1
In this example, the internal soundcard (hw:0) is an Intel HDA, and the
external USB card (hw:1) is an Aureon 5.1 MkII. On the internal Intel
HDA card, two separate devices are listed. The first, hw:0,0 is shown as
the analog output device, and the second, hw:0,1 is shown as the digital
output device.
Cheers!
Daniel
