35 second delay before playback

[pcwii]

I am trying to troubleshoot a playback delay on my new setup and not sure where to begin.
My setup is as follows.
I have a snapcast server running in docker on computer #1 (homeserver.local).
I have setup tcp streaming from computer #2 using parec --rate=48000 --format=s16le --channels=2 | nc homeserver.local 4956
I have snapcast android client running on phone #1

Now if I start audio playback on computer #2 it will take ~35 seconds before the audio begins to play on phone #1.

Is there a buffer setting on the server side that could be causing this?
Thanks for a great piece of software!
