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. Thanks in advance, Reetesh _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
