Re: Motu 1248 - Full success

[Anders Hellquist <lau@xxxxxxxxxxxxx>]

I just bought a couple of Ultralite AVBs the other day since I got a really good offer.

Have not received them yet so I have not tested them.

I have been following for some time the development of the openAVB project and I really hope this standard is getting more widely spread.

What I cannot understand (well I can understand but not embrace) is the fact that every vendor except AVB-switch vendors have their own implementation and by design make their products compatible only with its own brand. The point with a standard is IMHO to make products able to talk to each other. Motu apparently enabled talking to some Avid

 equipment some time ago with a new firmware but non-Avid brands are not compatible AFAIK.

I guess this is only marketing trying to protect their own brand more than a pure technical decision but correct me if I am wrong.

Do you guys think that AVB devices "firmware" easily cold be changed by the vendor to accept and cooperate with other avb streaming equipment ?

Do you think it is possible to reverse engineer the vendor specific protocols like for instance the FFADO project has been doing with firewire to make future openAVB implementations for the linux kernel if one is using appropriate hardware (intel i210 or similar) ? Or is this already possible ?

Best regards, Anders

Hello.

Thank you for your report on this 1248.

I've made the report on the ULTRALITE AVB in march.
[http://lists.linuxaudio.org/pipermail/linux-audio-user/2017-March/107629.html]
I've finally bought one, and since 1 month, it runs without any
troubles.

I think it's safe to say that the AVB serie (1248 / 624 / ULTRALITE) is
working  for Gnu/Linux.

I'm maybe missed it, but which distro are you running this card on ?

Did you register your product on MOTU web site, and add a comment that
you running it with Gnu/Linux. I like to believe that each voice
count :)

You surely see that, but you can, thanks to the routing matrix, have
near 0 latency on hardware monitoring while recording (guitar/vocal)
nothing goes through the computer. You also have to set the option in
your DAW to use hardware monitoring.

Yeah ! But like Len Ovens said on the ULTRALITE report, it's more «side
effect» of IOS...than a real Gnu/Linux support. They just repected USB
CLASS audio  «standard» [lot of other brands claim to be Class
compliant, but you do not have the softwares to control the card, so
useless ] and embedded the usually softwares they ship for Win/Mac
inside the card. Anyway it work !
