I'd like to be able to query the capabilities (number of channels, buffer
size etc.) of ALSA devices in the system, even if they should be in use by
some other process. The only current way to probe device capabilities is
to open a pcm, and use snd_pcm_hw_params, correct? At least this is my
current approach, but I'd like to query the devices without first
acquiring exclusive access. If there is currently no way around acquiring
a device for querying, maybe this requirement could be loosened in a
future version of ALSA?
