Because the "hw" device goes straight to the hardware and disallows any conversion of sample rate/format. Use "default", or something like "default:0" to select a specific card. > snd_pcm_set_params(handle, SND_PCM_FORMAT_S16_LE, SND_PCM_ACCESS_RW_INTERLEAVED, > channelz, samplerate , 0, 500000) ... and setting soft_resample to 0 disallows resampling in any case.
