Description Adam Dingle 2010-08-17 19:11:02 UTC 
Today, the alsasrc and alsasink elements have a property "device-name" which reveals the ALSA device name (which ultimately comes from the ALSA function snd_pcm_info_get_name).  They should have an additional property "card-name" exposing the ALSA card name (from snd_ctl_card_info_get_name).

For example, on my machine the device name for hw:1,0 is "USB Audio", which is currently visible via GStreamer.  The card name is "FastTrack Pro"; I'd like to be able to get this string too.  This would be useful for GStreamer applications which want to present descriptive ALSA device names to the user.
