Hi Guix,

Can anyone help me get my audio working?

I've been trying to "install" some configuration files for my audio 
setup on a Chromebook. On a normal GNU/Linux system, one installs them 
under /usr/share, but Guix doesn't have that, so I made a package based 
on alsa-ucm-conf.

But packaging the config files is not enough, it seems. You also have to 
modify alsa-lib, which efraim was kind enough to do last night.

But apparently, alsa-lib needs updated to support certain features of 
the config, so the attached Scheme code will not work. Can someone show 
me how to get it to work?

Thanks,

Caleb Herbert

Hi Guix,

I still need help getting audio to work.  I recently updated the code to
the package.

I'm still trying to package these ALSA configs, but alsa-lib might need
to be updated.

https://codeberg.org/csh/guix-channel/src/branch/main/kolev/packages/linux.scm

I haven't packaged anything before.  I don't know how to get this whole
thing to work.

Thanks,
