please, bear in mind two rules:
1. don't just reply to me, but always use the "reply-to-all" feature

the discussion and chime in.
2. don't top-post, always reply using proper quoting.

Things are a little more complicated as modern Linux distributions use
techniques like initramfs.
For Ubuntu, you should follow one of the tutorials. Two I found are here:
That looks comprehensive. Just don't download the ubuntu Kernel
sources as described but clone the ALSA repository (which you already
And instead of downloading the patches as described, just use "git
apply" on the file I sent you. On case you want to revert the patching
and return to the kernel you originally cloned, just call "git reset

I would first go for a normal kernel configuration, and once the
driver supports the device, care for optimisation.
