audio(9) says low level drivers are allowed to change the requested
values of the audio_params structure during AUDIO_SETINFO if the hardware cannot be set to exactly the requested mode. some drivers do this sometimes. others always return EINVAL if there isn't an exact match. be more consistent. only return EINVAL if an absurd parameter was requested, otherwise return a supported set of parameters, as close as possible to what was requested. with/ok ratchov@
