Hi Bob, Few weeks ago I was trying "rtl_fm ... | aplay ..." on a raspberry pi, but all I got was very choppy audio. There was no significant CPU load and if I used rtl_fm and aplay separately they worked just fine. Perhaps they changed something in the kernel configuration that lead to this behaviour. Do you remember which OS configuration used to work for you? Alex
