So I got lucky to hit the only card that doesn't get sound, card is recognized but there's simply no sound and I read that it's related to https://bugzilla.kernel.org/show_bug.cgi?id=55541 what are the steps, if possible, to compile my custom kernel to include that fix ?
I'm also using a Y splitter so speakers + headphones redirect to the same hole.
Edit: It goes without saying (right?) that you should check systemsettings > sound and make sure you're not muted, and have the proper output picked.
There's no reason to compile anything. As of kernel 4.18 or 4.20 (I don't recall which) the Soundblaster Z has been included. It's possible you just need the "linux-firmware" package.
Not knowing what kernel you're currently on, run the following in a terminal:
sudo apt-get install --install-recommends linux-generic-hwe-18.04 xserver-xorg-hwe-18.04 linux-firmware
And then reboot once done.
If that doesn't work, open up a terminal and type "alsamixer". If you have other sound cards in your pc, hit F6 and pick the one that says "HDA Creative", and make sure the different outputs aren't muted. Once you're done fiddling around, exit by pressing Esc, and then type "sudo alsactl store", fill in your password.
I have no idea are you using the 32 -bit architecture and Elementary OS as far as I know is 64 bit, so reading this comment from the website you mentioned is crucial:
mmstick 2014-01-10 05:20:49 UTC The problem has been known since 2011 pretty much. There's no fix that I have found other than using 32-bit or buying something else, like an external USB DAC or a supported ASUS card. When you do get it to work in 32-bit, you can't use the equalizer unless you manually patch the patch_ca0132.c file yourself. I have no idea why the issue with 64-bit hasn't been fixed yet, nor why the equalizer is not enabled by default.mmstick 2014-01-10 05:20:49 UTC The problem has been known since 2011 pretty much.
