Hi,
I have a Behringer UMC1820 that served me well in many multi-channel concerts I played.
Now I need a few more channels, so I borrowed an ADAT expander (a re-purpused MOTU
Traveler mkIII Firewire interface).
I tried with two laptops, one Lenovo IdeaPad Flex 5 (11th gen Intel I7) and one Lenovo
ThinkPad T14 Gen 3 (12th gen Intel I7).
Other than that, both laptops have the same configuration. Arch Linux (updated today),
Pipewire, Wireplumber, all drop-in replacements for pulse, Jack, etc,
down to the same pipewire.conf (I copied that over).
Here's the weirdness:
On the ThinkPad, all ADAT output channels of the Behringer work, I can see the lights
blinking and hear the sound.
On the IdeaPad, only ADAT output channels 5-8 work, channels 1-4 are dead.
I've tried different USB ports and so one, but nothing made a difference.
An ideas where I could look? Could there be a setting I missed?
Best,
N

Can you re-check if you run the same samplerate on the IdeaPad and are
not running into some 96kHz multiplexing issue?
Not that I think if it I remember that I had dead channels just like you
on the same interface when I borrowed it a year ago for a few weeks but
on the analogue outputs I think.
Not much of help I am afraid...

Hmm the samplerate is the same, the Behringer acts as the main clock. The right lamps
light up on the ADAT expander, etc ...
