Question about getting the name of devices

[Julien Puydt <jpuydt@free.fr>]

Hi,

I'm trying to patch the alsasrc&alsasink gstreamer plugins to be able to 
show nice names in user interfaces.

Given a card number, using snd_card_get_name gets me what I want easily. 
Unfortunately, that's not what I have available : I just have a 
snd_pcm_t*, opened on a char* which may look like "hw:1,0".

I know that I can snd_ctl_open a snd_ctl_t* with "hw:1", then get a 
snd_ctl_card_info_t*, on which I can call snd_ctl_card_info_get_card, to 
finally be able to call snd_card_get_name (sic).

The problem with this approach (well, apart from the fact that it is 
overly complex), is that snd_ctl_open fails if something like "hw:1,0" 
is given to it.

Is there a sane and simple way to obtain the name of a card from the 
data I have ?
