Hi Alsa developers/users,

For some reason my message got truncated earlier. So here I go again.

I'm using snd_device_name_hint("pcm"..) and then snd_device_name_get_hint(.."NAME") to get the NAME parameter of pcm devices. Is it true that all sound cards that support Alsa will *always* have "default" pcm device?

At least for the sound instances from the kernel drivers, yes. Not always true for sound devices implemented via plugin (e.g. bluez), though.

I'm more inclined towards using "default:CARD=<vendor>" as the parameter to snd_pcm_open(). This way if the program configures hardware params for any number of channels then the appropriate PCM device will be selected on the sound card, correct?

Yes.
