[LAU] USB audio interfaces with more than 16 digital output channels ?

[Niklas Reppel]

Hi,

i'm currently looking for interfaces that have more than 16 digital 
outputs for higher-order ambisonics
applications.

One of my requirements would be that they work with recent laptops, that 
is laptops that don't have
expresscard or firewire interfaces, as those unfortunately aren't built 
any more.

I've stumbled over a LAU post from 2016 where options were discussed.

There's the DiGiCo UB Madi that is reported to work, but the price is 
ridiculous, and also it seems
rare/hard to be obtained or even out of production.

The RME Madiface USB aren't working at all (tried one of them myself).

So, the PCIe and ExpressCard versions of the RME MADI interfaces have 
been reported working,
but has anybody ever tried to use them with USB-to-PCIe or 
USB-to-ExpressCard adapters?

Otherwise, ase the market brought forth new options ?

Any advice is appreciated !

Best,
Niklas
