Oh, you made me dig into AES67 :-) But yes, this would need some sort
of driver to make AES67 work.

AFAICS, latency is not a problem on modern systems. On a cheap 100Mbps
ethernet link, TCP just works and latency is largely dominated by
audio interface latency (provided that there's enough bandwidth
available for audio). Hence the TCP choice for sndiod.

Bandwidth could be reserved with the firewall, but getting a dedicated
network interface, solves all stability/latency problems.

Never tried, as I never needed it.

I'm curious, what speakers are these?
