Issue Piping Audio to Line out on the Raspberry Pi

[stillline]

Stillline

Expected Behavior

I am piping p25 encoded audio from an SDR through rtl_fm and into dsd. I would like it to output the decoded voice audio to the raspberry Pi headphone/Line Out jack.

Actual Behavior

With the command I am suing DSD receives the aduio just fine and gives me text output that shows it is in fact deocding voice, however no sound plays through the audio jack.

I am using the command:
rtl_fm -f 442.83125M -g 45 -s 16k | sox -t raw -r 16k -b 16 -c 1 -e signed-integer - -r 48k -t raw - |
PADSP DSD -i - -o - /dev/dsp

I know this command is a mess I believe the releavnt part is |PADSP DSD -i - -o - /dev/dsp

What is the correct method to pipe audio on the RPi3

I have also tried
DSD - i - -o - /dev/dsp

PADSP DSD -i - -o - /dev/dsp

DSD -i - -o - aplay

PADSP - i - -o - PA:2
