[LAU] Multichannel analog I/O audio interface: experiences and tips

[Philippe Bekaert]

Most of the pcie cards (in fact, all of them in single speed mode) work absolutely fine on my laptop, given a sonnet echo express IIIe thunderbolt to pcie box. 

As said, my set up set me back more than 700 euros …

I have a rme Dante-to-madi usb box here. Never checked usb audio class compliant mode. Will do. 

Best, ph
