Hello.
I m just getting my head around the whole lot of ethernet audio protocols avaliable, it's a big deal of brands really ..
but now it looks like there will be a new rather standard protocol - ieee802.1 ethernet AV bridge.
here is a reference design which includes driver source-code. i haven't quite figured is tha tlicene is comptible with gpl really.. but i suppose you don't need to use that code, just look at it as a piece of documentation ..
it could be so great to have ethernet audio in linux!
i have seen the audio science interface and draver exists, but they are using cobra-net ..which is probably good, but it's not as standard as ieee AVB.
here you can find an article about the current status of the protocol mess: http://prosoundnewseurope.com/pdf/PSNLive/PSNLive_2009.pdf (page 28)
best regards,
