On a Dell cfl machine, install the eoan on it, boot the system and check the dmesg, the sof driver print a error log "can't find the firmware sof-cfl.ri" and audio doesn't work after boot.
enable the proposed, sudo apt-get update;sudo apt install linux- firmware, now the linux-firmware 1.183.6 is installed. reboot the system, check the dmesg, there is no that error anymore, and after boot, the audio works well. verified it works on eoan -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-firmware in Ubuntu. https://bugs.launchpad.net/bugs/1875263 Title: linux-firmware: missing sof-cfl.ri symbol link for Bionic and Eoan Status in OEM Priority Project: New Status in linux-firmware package in Ubuntu: Fix Committed Status in linux-firmware source package in Bionic: Incomplete Status in linux-firmware source package in Eoan: Fix Committed Bug description: [Impact] some ubuntu eoan/bionic users reported that the audio driver failed to initialize, then the audio didn't work. I checked the dmesg, found the sof driver planed to load sof-cfl.ri, but there is no this firmware under eoan or bionic. [Fix] I consulted with Intel audio team, they told me that the coffeelake platform could share the firmware with cnl/whl platoforms, so we could build a symbol link sof-cfl->sof-cnl. [Test Case] A couple of ubuntu users already tested it on Dell and Asus coffeelake laptops, it worked well. [Regression Risk] Low, users already tested it, and Intel audio team confirmed it is safe.
