ETH-68 Ethernet Audio Interface
The most recommended of 3 audio interfaces
People recommend this Ethernet audio interface for its low latency, high channel count for the cost, and long reliable production record. Critics note it is limited to 48 kHz and uses a default IP address in public space.

Why people recommend it
Each mark is one comment
Low round-trip latency, about 3.6 ms
“It's a hardware audio interface with a very low latency (buffer of 64 samples, 3.6 ms)”
Comment from 9 Oct 2026 in “ETH-68: Ethernet Audio Interface for Linux” “ETH-68 matches the round trip audio latency of this card at 48 kHz”
Comment from 8 Oct 2026 in “ETH-68: Ethernet Audio Interface for Linux” Cheaper alternative to RME
“something akin to what you are doing would be a much more fun and less expensive option than RME”
Comment from 9 Oct 2026 in “ETH-68: Ethernet Audio Interface for Linux” “Having a low-cost, infinitely more portable solution would be very welcome.”
Comment from 8 Oct 2026 in “ETH-68: Ethernet Audio Interface for Linux” “this is fantastic, and if the $$$ is not crazy, I would want this for sure.”

What people warn about
Each mark is one comment
Default IP in public address space
“It would be better to choose an IP address in one of the private spaces for this purpose.”
Comment from 9 Oct 2026 in “ETH-68: Ethernet Audio Interface for Linux” “eth68 sends capture packets to 12.12.12.10:3000 by default.”
Comment from 8 Oct 2026 in “ETH-68: Ethernet Audio Interface for Linux” “I hate private projects pooping on public spaces.”

“OK I tried this out and it works”
“this is fantastic, and if the $$$ is not crazy, I would want this for sure.”
“something akin to what you are doing would be a much more fun and less expensive option than RME”
“Neat stuff. I'll probably never use it, but it's neat.”
“It's a hardware audio interface with a very low latency (buffer of 64 samples, 3.6 ms)”
“I think this would be a cool project to do as a DIY.”
“It would be better to choose an IP address in one of the private spaces for this purpose.”
“why the limit on sample rate? why not also support 44.1 kHz ?”
“ETH-68 matches the round trip audio latency of this card at 48 kHz”
“it has been reliably in production for around 20 years, and has a high channel count to cost ratio”
“It's far from top of the line and it's not like the design is tight on space.”
“I hate private projects pooping on public spaces.”
“Having a low-cost, infinitely more portable solution would be very welcome.”
“eth68 sends capture packets to 12.12.12.10:3000 by default.”
“Even as not-audiophile, I’ve got ideas of things to use this for.”
“4ms is pretty good but I feel like sub 2ms would be nicer.”
