Hi,
sorry for those general questions, but I wasn't able to find anything on the
archives or in the ALSA documentation.
What is the meaning of devices vs. subdevices ? What is an example where a
device would have several subdevices, as opposed to the card having several
devices ? I want to display a list of available "ports" where the user can send
the audio generated by the program. If a device has several subdevices, would I
include them in the list, or just list the devices for each card ?
My program successfully lists the cards with their devices and subdevices for
hw: (i.e. snd_ctl_open("hw:0") ). However, this does not work for the plughw:
way, although from what I understood, I want to use plughw: (as it supports
automatic sample rate conversion). How do I iterate all available plughw: cards,
devices, and subdevices? Or can I assume that if hw:0,0 exists, that plughw:0,0
is the same card/device ?
Thanks!
Florian
