The default device is not "hw:0,0" but "default" which gets eventually mapped to "plug:hw:0,0". > on my first card, the first subdevice is an mono channel. The subdevice number would be the third number (as in hw:0,0,0). The first device on your first card has exactly one subdevice which has exactly two channels. A card has more than one device if it has several output/inputs that can be used _independently_ (i.e., if the hardware can play from different streams). For example, the analog and SPDIF outputs of Intel compatible AC'97 controllers are available as hw:0,0 and hw:0,4. A device has more than one subdevice if the hardware can mix several streams for the same output. > > HTH > what means HTH ;=) Hope this helps. Clemens
