On a Dell machine with Bionic on it, enable the proposed, sudo apt-get update; sudo apt install linux-firmware, now the linux-firmware-1.173.19 is installed.
First check if those 2 symbollink exists by ls -la /lib/firmware/intel /sof-tplg/ Then install the linux-kernel-5.4 on the bionic, boot the system with 5.4 kernel and check dmesg, there is no "tplg is missing" errors in the log and audio works fine. Verified the bug is fixed by 1.173.19. -- 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/1880623 Title: linux-firmware: generate the symbollink of sof-hda-generic- 2ch/4ch.tplg for bionic Status in HWE Next: New Status in linux-firmware package in Ubuntu: New Status in linux-firmware source package in Bionic: Incomplete Bug description: [Impact] Users install the focal kernel on the bionic, the sof driver in focal kernel will fail to load the tplg files. [Fix] generate the symbollinks according to the requirement of sof driver in the focal kernel. [Test Case] booting the focal kernel on bionic, the sof driver could load the tplg successfully, and the audio works well. [Regression Risk] Low, the bionic kernel will still load sof-hda-generic.tplg, there is no any impact on the original bionic kernel + linux-firmware.
