Hi,
I'm trying to use tinyalsa on am335x evm board running android ICS (TI-Android-ICS-4.0.3_AM335x_3.0.1).
As first step I used tinyplay for testing if all was ok out of the box, but it doesn't seems to work.
I create two pcm raw .wav files the first one 44.1Khz and the second one 48Khz, both 16bit stereo, I tried to play them this way:
#tinyplay <filename.wav> -d 0
I saw the sound devices in /dev and they seemed to be not occupied
but I had this output:
#Unable to open PCM device 0 (cannot set hw params: Invalid argument)
I can't understand what kind of problem should be, the audio from android media player works fine and tinymix seems to be set:
