I have a Creative Soundblaster Z SB1570 (yeah I know big mistake) and I read somewhere that the 4.18 kernel will have better support for this card. My question is how can I make it work earlier using this kernel before the kernel update will be released officially to all 18.04 users? I read also that there is a patch for this card. Is this needed as well?
I am sorry if my question is too broad, but basically I need the steps that I need to follow in order to make the sound card work properly.
P.S.: I tried myself to install this specific kernel and I succeeded, but I didn't get the sound card to work properly.
EDIT:
Install Updated Kernel
Per this link, you can manually update to kernel 4.18. If your device is reported to work with this kernel, theoretically it should work out of the box:
Download the kernel here:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.18/
Download required files into a folder, say ~/kernel, then:
Once you have rebooted, verify your kernel with:
If for some reason you want to get rid of this kernel
Reboot, go to advanced boot options and select a different kernel and boot. To remove 4.18 run this command:
( you will have to change the package name according to the kernel you installed )
Confirm Sound Card Works
Reboot and see that your audio card is recognized using alsamixer:
You may need to change the number next to the flag -c depending on the sound card you want to choose and edit its settings.
You can adjust levels here. According to answer found by OP, the HP/Speaker output needs to be muted for other outputs to work.
I am using an ubuntu kernel updater ukuu http://www.teejeetech.in/p/ukuu-kernel-upgrade-utility.html
And I upgraded the kernel to 4.18.3 . My creative sound blaster Z is finally working. Hope it works for you also.
