** ALSA_PerformDefaultScan
|
|
** Perform the basic default scanning for devices within ALSA.
|
|
** The hope is that this routine implements a 'correct'
|
|
** scanning algorithm from the Alsalib point of view.
|
|
**
|
|
** Note that Wine, overall, has other mechanisms to
|
|
** override and specify exact CTL and PCM device names,
|
|
** but this routine is imagined as the default that
|
|
** 99% of users will use.
|
|
**
|
|
** The basic algorithm is simple:
|
|
** Use snd_card_next to iterate cards; within cards, use
|
|
** snd_ctl_pcm_next_device to iterate through devices.
|
|
**
|
|
** We add a little complexity by taking into consideration
|
|
** 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
|
|
** and audio scaling, if they are available).
|
|
** devscan If TRUE, we should scan all devices, not
|
|
** juse use device 0 on each card
|
|
**
|
|
** Returns:
|
|
** 0 on success
|
|
**
|
|
** Effects:
|
|
** Invokes the ALSA_AddXXXDevice functions on valid
|
|
** looking devices
