I am rather confused that I am getting crossed information when calling snd_names_list and snd_pcm_info in order to gather information about pcm devices.
I think ALSA's new device enumeration API can do this for you. See the implementation of aplay -l (or -L, don't remember which) in the latest alsa-utils.
Ok, thanks for the hint (no pun intended :) ).
I see that the pcm_list() function has changed in aplay. The new hints API looks good.
However, I note that snd_device_name_hint() does not return hw, plughw, plug, dmix, etc. Are these obtained elsewhere? I would like to build a complete list of all available devices in order to allow the user to select them from a dropdown list in a GUI.
They are not shown unless you give the device description explicitly or set a global flag. See the description of snd_device_name_hint() function.
