Hello, I recently bought the Moto M4 audio interface, especially to carry out measurements on my do-it-yourself Blue Note 2 speakers from ADW Germany. I would also like to use it to measure amplifiers and possibly digital electronics.
Since I still have a raspberry Pie 4 here, I came up with the idea of building a cheap streaming system and bypassing the internal I2S connection and operating the Moto M4 via USB. After some research I decided on Moode Audio (7.2.1 as of June 25th) and alternatively I run Raspberry OS with KODi with a second micro SD card. Both systems work well via the analog output with all the limitations of the user interface (compared to Bluesound or Teufel Audio often used here in Germany).
My problem is that the Moto M4 does not accept playback via USB or the Raspberry does not recognize the Moto 4.
Instructions for solving this problem can be found at https://github.com/raspberrypi/linux/issues/4116 and https://community.roonlabs.com/t/motu-m2-support/125769 and https://www.gitmemory.com/issue/raspberrypi/linux/4116/777422452
I had also discovered a hint that the solution was an active USB controller. However, neither the active controller nor the use of various USB cables resulted in a sound output via the Moto M4 in my system. Maybe someone has solved the same problem and can name it here. Further ideas and suggestions for a solution are also welcome.
I don't want to give up yet, but the alternative would be a mini PC like Intel nuc and Windows 10. I know that it works and is good too ...
