Description of problem: The current version of the alsaaudio binding requires (in more than one sound card environment) the name of the card. I propose to add Cards interface to get non-interactively the list of the connected cards. Additional info: The two attach is for sources and spec file. After file this bug I'll send the copy to the maintainer email. Thanks.

python-alsa is a native python ALSA bindings. The package already has been included the described method (by functionality) to get cards list. So, I close this bug and switch my own software to the python-alsa.
