Maybe he was thinking of the ALSA project then - I haven't heard back 
from them yet, but I'd guess they're busy getting ready for the 
Karlsruhe conference.

I think (or hope) that we are moving into a new phase where 
manufacturers are more actively involved in Linux support for their 
audio products. So hopefully volunteer time won't be so much of a 
constraining factor in future.

Exactly which format do you need this firmware in? Presumably you have 
the binary already for the particular device you are testing on?

Wouldn't sample hardware on loan + firmware be better? I don't think 
that's impossible to arrange. If it makes these companies feel more 
comfortable about sending the hardware out, we could arrange for the 
Freebob project to become a member of linuxaudio.org - you'd be most 
welcome of course. (It doesn't cost anything to join).

Yes indeed, although it has other functions on top of the audio 
interface, such as DSP effects. I'm guessing this will need some kind 
of control application on top of the userspace driver.

There is a list here:


According to this page, the mLAN spec is royalty-free and there is a 
BridgeCo chipset for it:


There are three kinds of mLAN licence:


As far I can see, driver development for a 'control node' requires a 
PTT (Patent, Technical information & Trademark) License.

This page says that among others, BridgeCo is a licensee:
