Thanks Takashi. If the lib does not provide the API to read the device capabilitiess, is there a way for applications to directly read it from the Alsa kernel driver ?

Hi all,
I am new to the group and to Alsa.
For our project, we have to find the max sampling rate and other pcm hardware parameters that the connected USB headset supports. I looked at the alsa library, but could not find an API which returned this information.
I found snd_pcm_hw_params_test_* function to test a specific value is supported, but I was wondering if there was a way to query the device to get the values.
The min / max can be obtained via *_get_rate_min() and *_get_rate_max(), at least. The other detailed information can't be get except for testing the explicit value via *_test_rate(), so far.
HTH,
