You have been subscribed to a public bug: After upgrading to 20.04, my onboard sound no longer seems to work. The motherboard is ROG Zenith. dmesg shows the following:
[ 9.266092] snd_hda_intel 0000:09:00.1: dmic_detect option is deprecated, pass snd-intel-dspcfg.dsp_driver=1 option instead [ 9.266556] snd_hda_intel 0000:09:00.1: Disabling MSI [ 9.266586] snd_hda_intel 0000:09:00.1: Handle vga_switcheroo audio client [ 9.267181] snd_hda_intel 0000:0b:00.3: Skipping the blacklisted device After searching for this message in kernel source, I happened upon this line: https://github.com/torvalds/linux/blob/052c467cb58748e302a95546925928e637025acc/sound/pci/hda/hda_intel.c#L2082 static const struct pci_device_id driver_blacklist[] = { { PCI_DEVICE_SUB(0x1022, 0x1487, 0x1043, 0x874f) }, /* ASUS ROG Zenith II / Strix */ { PCI_DEVICE_SUB(0x1022, 0x1487, 0x1462, 0xcb59) }, /* MSI TRX40 Creator */ { PCI_DEVICE_SUB(0x1022, 0x1487, 0x1462, 0xcb60) }, /* MSI TRX40 */ {} }; Which led me to this bug report: https://lore.kernel.org/alsa-devel/20200424061222.19792-1-ti...@suse.de/ I confirmed that the PCI device that is not working appears to match the vendor ID: $ lspci | grep 0b:00.3 0b:00.3 Audio device: Advanced Micro Devices, Inc. [AMD] Family 17h (Models 00h-0fh) HD Audio Controller $ lspci -n | grep 0b:00.3 0b:00.3 0403: 1022:1457 Unfortunately, I am unsure how to test a Ubuntu compatible kernel with these changes but it appears there has been some jiggery pokery in Linux kernel land in this regard.
