Fine.
However, when triyng to play something I get this:
asoc: machine hw_params failed
This is in sound/soc/soc-core.c, line 494. I couldn't go any futher then this. Any hint?
This combination of processor, crystal and codec only supports the following rates: 11.025 Khz, 22.050Khz and 44.100 Khz
Please try to play a file with these sample rates. (If you have alsa-tools, you could try 'speaker-test -r 44.100').
BTW, could you tell me the freq of the crystal on the processor board ? (Is it 16.934 Mhz?)

Hi,
I used speaker-test as indicated above and the result is:
pendrive $ ./speaker-test -r 44100
speaker-test 1.0.11
Playback device is default Stream parameters are 44100Hz, S16_LE, 1 channels Using 16 octaves of pink noise ALSA lib pcm.c:2146:(snd_pcm_open_noupdate) Unknown PCM default Playback open error: -2,No such file or directory ALSA lib pcm.c:2146:(snd_pcm_open_noupdate) Unknown PCM default Playback open error: -2,No such file or directory ALSA lib pcm.c:2146:(snd_pcm_open_noupdate) Unknown PCM default Playback open error: -2,No such file or directory ALSA lib pcm.c:2146:(snd_pcm_open_noupdate) Unknown PCM default Playback open error: -2,No such file or directory ALSA lib pcm.c:2146:(snd_pcm_open_noupdate) Unknown PCM default Playback open error: -2,No such file or directory
I have also tried:
/pendrive $ ./aplay -f cd 01-jack_johnson-times_like_these-rns.wav ALSA lib pcm.c:2146:(snd_pcm_open_noupdate) Unknown PCM default aplay: main:547: audio open error: No such file or directory /pendrive $
so I don't know what is happening here. Does anyone have any idea?
Thanks, Henrique
