Very happy to ue my Khadas Vim for making music. I’m using an external soundcard (USB) successfully (both input/output). What is not working is the alsa-midi stuff.
I tried to:
sudo modprobe snd_seq
modprobe: ERROR: ../libkmod/libkmod-module.c:832 kmod_module_insert_module() could not find module by name='snd_seq'
modprobe: ERROR: could not insert 'snd_seq': Unknown symbol in module, or unknown parameter (see dmesg)
modprobe: ERROR: ../libkmod/libkmod-module.c:977 command_do() Error running install command for snd_seq
modprobe: ERROR: could not insert 'snd_seq': Operation not permitted
Any program that needs to access midi will failed like this: ALSA lib seq_hw.c:457:(snd_seq_hw_open) open /dev/snd/seq failed: No such file or directory
Do I need to recompile the kernel to loads the modules (alsa midi snd seq stuff)?
@Terry Thanks I was able to build Ubuntu-Mate using the Fenix script (kernel 4.9). But still no snd_seq modules loaded.
What step & what file should I modify to add CONFIG_S(OU)ND to the final .img? I see in the packages/linux-mainline/patches some interesting files that looks like it (adding options to defconfig), but really not sure how to proceed.
