For ultralite AVB, there is a hack to switch to proprietary mode and get more channels again. I guess it will work with any Motu AVB device but have not tested it myself.

Check this posting.

Hi everyone,

sorry for taking so long, but only now could I check the newer firmware.

It seems that Motu removed the possibility to change channel count in the device menu.
I wasn't able to configure this with Cadence either, so long story short I didn't succeed getting it to work with the new firmware.

Best regards

According to Motu support, they suggests downgrading whenever there is s problem. My understanding is that that is s fully supported operation. In newer Motu firmware, there seems to be a new bios mode that could possibly be some kind of recovery is for extra safety.

Thanks, I saw that actually. But it doesn't mention Linux compatibility...
Question - can you 'update' to an older firmware on Motu interfaces? If
so, maybe try newer ones and see if they work?
That is actually something I did, I downgraded to the last working version after an update broke my system.
But now I'm a little afraid that it could stop working, it happened to me with other pieces of hardware (not linux related) that after a specific update I could not downgrade anymore.
