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? -pharaoh.
