Linux Support

Post by jsmarti »

I would like to know about discussions regarding Linux support for MOTU devices. I am particularly interested in Ubuntu 18.04 drivers for the MOTU 24 Ao interface. I do particular work with these devices which is not necessarily constrained to audio. In general, I try to use the PortAudio library to send different types of waveforms to this 24 channel device.

I wonder if there is any kind of drivers for MOTU on Linux. If not, what would be a solution to this problem?

Write your own driver.

Get someone else to write a driver.

Petition MOTU maniacally.

I know there are people working on Firewire and USB drivers for audio interfaces for Linux, but I think you need a class-compliant device, like the smaller interfaces from M-Audio, Scarlett, Roland/Edirol, etc.

A solution I was afraid of unfortunately. I have no experience writing drivers and I am constrained to using this 24 channel device (Ao 24).

The interesting thing is that to send data to the channels, I use the PortAudio I/O library. A simple code to play a sinusoidal tone on Windows (drivers installed) plays smoothly. The same code ran on linux plays a sinusoidal pattern of some kind of distorted wave. What shocked me is that it actually plays something and has a periodic pattern of the specified duration.

I though that I could find a workaround to the driver problem somehow since I am still able to play data into individual channels for a fixed duration.

The motu 4pre works with the FFADO drivers.
