Does ALSA automatically convert to my devices sample rate? My alsa.conf file is below
pcm.mix { type dmix ipc_key 1024 slave { pcm "hw:0,0" rate 48000 } } pcm.!default { type plug slave.pcm "mix" }
When I play a 32KHz file with aplay does it get up sampled to my device's 48KHz sample rate? I am assuming it does as it plays just fine but I am not sure where the upsampling happens?
Thanks.
