Make error #7

Hi Drumfix,

Thanks for providing this code! I have a MOTU 24Ao in the lab and am trying to control it from a PC running Ubuntu 20.04. I am also experiencing some issues with it suddenly stopping in the middle of playback and channels switching (especially when using an USB extension cable between sound card and PC) and I was hoping this driver would fix that. However, I have some problems compiling and installing the driver and was hoping you could help. I have only a little programming experience, so sorry if this is a trivial question.

So, I installed the kernel source code by downloading it from https://github.com/zen-kernel/zen-kernel/tags and extracting them into/lib/modules/uname -r/source as @ozel suggested. But when I try to run make I get the following: Copying required header files from kernel sources...

I don't know if this is an error or just a warning that can be ignored, but if I then try to do sudo make install I get the following errors: _make -C ""/lib/modules/5.11.0-41-generic/build"" M="/home/audiologie/Documents/motu-avb-usb-main" modules_install make[1]: Entering directory '/usr/src/linux-headers-5.11.0-41-generic' INSTALL /home/audiologie/Documents/motu-avb-usb-main/motu.ko At main.c:160:

Apparently your system allows only signed modules to be added.

 

Can you load it by:

 

sudo modprobe snd-usbmidi-lib

sudo insmod ./motu.ko

 

from the directory the motu.ko was built?

 

Guess i have to make a dkms module.

Can you load it by: sudo modprobe snd-usbmidi-lib sudo insmod ./motu.ko

No, unfortunately the second command gives the error "ERROR: could not insert module ./motu.ko: Operation not permitted". It would be great if you could make a dkms module! Is that a lot of work?

Drumfix commented 2 years ago

Are you using a dual boot with windows ? In that case make sure to temporarily disable secure boot in the BIOS for the installation to succeed.

MartyME91 commented 2 years ago

Thank you for your advice. I disabled the secure boot and still can't do the normal sudo make install, but doing sudo modprobe snd-usbmidi-lib and sudo insmod ./motu.ko do not result in errors now. When I do lsusb -t it says "Driver=snd-motu-avb", so it seems to work! Unfortunately the issues with playback stopping and wrong channel order are still present though :-( so maybe the problem was the usb extension cable after all.

MartyME91 commented 2 years ago

Issues also occur without the usb extension cable, only less often. So it's not that, it only makes it worse. I don't know.
