I have been using jackd to play music from my laptop -> server -> hifi.
Have you also tried zita-njbridge?
It has been some time since I tried netjack (or zita-njbridge). At
least one machine upgrade...
Also, you may want to look into open AVB which has jack to jack
capability and with the right nic will allow your audio stream to have
priority over other network traffic. But it is more to set up.
In any case, if there is more than one audio card some resampling will
have to happen (even with AVB with most consumer AIs). In the case
above, your hifi will have to be master I am not sure in that case why
there would be a server in the middle, but it looks like you have the
server getting it's sync from the hifi and then the laptop gets it's
sync from that? Is the network used for other things besides sound? Is
audio traffic prioritized? In all machines? In any switches?
Looking into AVB and or AES67 and the requirements for no dropout
sound may be helpful. Netjack is designed for single hop, no other
network traffic, no switch, audio transport. zita-njbridge is designed
to handle switches and some other traffic a bit better. The standard
streamers like icecast, etc. use long latency end to end (500ms or
more) to avoid dropouts.
So in the end you have to choose your own priorities in sound quality
and latency as well as how much money you want to spend and how much
time setting it up.

Thanks. I'll look into those. It is a single hop (well two if you
include the router itself). I have never setup any sort of priorities
for traffic. My router has some control over traffic priority, but
only for wireless it seems.
