Hi
I get following error when trying to run aplay with my plugin:
#aplay -D myplug test.wav
Playing WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, St
ereo
aplay: set_params:882: Broken configuration for this PCM: no configurations
available.
After looking at the code, I figured out that its snd_pcm_hw_refine which is
causing problem.
It looks like following in pcm_params.c in alsa lib 1.0.13,
int snd_pcm_hw_refine(snd_pcm_t *pcm, snd_pcm_hw_params_t *params)
{
int res;
#ifdef REFINE_DEBUG
snd_output_t *log;
snd_output_stdio_attach(&log, stderr, 0);
#endif
printf("#####%s \n", __FUNCTION__);
assert(pcm && params);
#ifdef REFINE_DEBUG
snd_output_printf(log, "REFINE called:\n");
snd_pcm_hw_params_dump(params, log);
#endif
printf("#####%s calling hw_refine\n", __FUNCTION__);
res = pcm->ops->hw_refine(pcm->op_arg, params);
printf("#####% return val of hw_refine = %d\n", res);
#ifdef REFINE_DEBUG
snd_output_printf(log, "refine done - result = %i\n", res);
snd_pcm_hw_params_dump(params, log);
snd_output_close(log);
#endif
return res;
}
I have modified the alsa.conf for my plugin by adding following in it at the
end,
pcm.myplug {
type myplug
card 0
}
What could be the problem?
