I'm having a hard time understand when ALSA does sample rate and format conversion, and when it doesn't.
Some more info:
I'm trying to play a movie with 441000 Hz audio.
If I specify "-ao alsa", mplayer calls snd_pcm_hw_params_set_rate_near() with a value of 44100. The call fails and returns an error code.
If I specify "-ao alsa:device=hw=0.0", snd_pcm_hw_params_set_rate_near() does not fail, even though it's being passed the same parameters.
So what is it about the default device that makes snd_pcm_hw_params_set_rate_near() fail?
