depends on the device the application opens.

If you tell it to open a device with a name like "hw:N" or "hw:CARDNAME"
then ALSA will offer only the capabilities present in the audio hardware.
If you open it with a name like "plughw:N" or "plughw:CARD" then ALSA will
do everything it can to honor the format, sampling rate etc. asked for by
the application (including resampling, channel multiplexing etc.).
