How to patch ALSA snd modules source and recompile kernel?
Hi, I'm trying to patch snd_usb_audio module on Arch.
On OpenSUSE I could just edit /usr/src/linux-x.x.x/sound/usb/pcm.c and recompile kernel using make oldconfig. However on Arch I don't see any files in /usr/src/linux-lts/sound. Why is that? Does it require some other package than linux-headers to be installed? Or does Arch do ALSA different way?

Re: How to patch ALSA snd modules source and recompile kernel?
Thank you. Wiki says that I should download source of the same kernel I have. Current Arch LTS kernel is 5.4.28-1-lts.
Is it the same as 5.4.28 kernel from www.kernel.org? (I mean is this ...-1 significant?)

If you look at the PKGBUILD for linux-lts, you will see that it downloads the 5.4.28 kernel from kernel.org.

I managed to compile kernel but now DKMS modules don't compile and system cannot mount VirtualBox shared directory. I copied kernel source to /usr/src/ but it didn't help.

What kernel did you build? How did you install it? What was the output from DKMS when it failed?
