Re: [LAD] AVB not so dead after all

It appears that at the same time as being a switch it could also be set up as an endpoint. There is I2S connections on it. So it could be a good starter set up with switch and 8audio i/o. I think, the spec just says: "Internal 20pin 0.1” pitch connector with TDM/I2S input & output streaming AVBTP (IEEE 1722) talker listener mode Up to 8ch per stream Sample rate of 44.1/48/88.2/96/176.4/192kHz Sample width of 20/24bit Automatic hardware locking to stream’s media using the IEEE 1722 presentation time" And last of all, This looks like a ready to run AVB interface that will work on Linux: http://www.dsp4you.com/downloads/AV2USB%20Datasheet.pdf I could not find the price though. It is limited to 8/8 i/o and looks to Linux as a class compliant USB 2.0 8channel audio card. Of course those 8 channels can be any of the available AVB channels on the AVB network. More than one of these could be used on the same computer for 16 channels (or more) as they are by default synced. I would suggest a variant of zita-a2j with no resample to connect 2nd and more units rather than making a "multi-device". This would allow plugging and un-plugging without stopping jackd. Also, if your "internal" AI has external sync capability (s/pdif or word clock) it could be used by the jack back end and av2usb boxes added as clients if at least one of the AVB audio IF boxes had a similar sync out. This may also be an inexpensive way of using network for audio transport from one computer to another in the same LAN with low latency. Two ethernet ports means a switch may not be needed. (aside from audio streaming a net port would be needed to control routing too unless that is somehow incorperated in the USB line) -- Len Ovens www.ovenwerks.net
