** Use snd_card_next to iterate cards; within cards, use

** snd_ctl_pcm_next_device to iterate through devices.
|

**
|

** environment variables such as ALSA_CARD (et all), and by

** detecting when a given device matches the default specified
|
||||
** by Alsa.
|

**
|
||||
** Parameters:
|
||||
** directhw If !0, indicates we should use the hw:X
|

** PCM interface, rather than first try
|

** the 'default' device followed by the plughw

** device. (default and plughw do fancy mixing
