** Description changed: I find this to be an issue with current LTS 18.04's latest 4.19 kernel. I tested this on mainline 4.20 and 5.0 kernels as well. No audio because ALC274 not properly loaded for use, so no audio output. A related card had a similar bug, which was fixed, and may be of use in resolving this one: https://bugs.launchpad.net/ubuntu/+source/alsa- driver/+bug/1784485 # cat /proc/asound/card0/codec* | grep Codec Codec: Realtek ALC274 Codec: Intel Kabylake HDMI # cat /proc/asound/card0/pcm0c/info card: 0 device: 0 subdevice: 0 stream: CAPTURE id: ALC274 Analog name: ALC274 Analog subname: subdevice #0 class: 0 subclass: 0 subdevices_count: 1 subdevices_avail: 0 aplay -l **** List of PLAYBACK Hardware Devices **** card 0: PCH [HDA Intel PCH], device 0: ALC274 Analog [ALC274 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: PCH [HDA Intel PCH], device 3: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: PCH [HDA Intel PCH], device 7: HDMI 1 [HDMI 1] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: PCH [HDA Intel PCH], device 8: HDMI 2 [HDMI 2] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: PCH [HDA Intel PCH], device 9: HDMI 3 [HDMI 3] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: PCH [HDA Intel PCH], device 10: HDMI 4 [HDMI 4] Subdevices: 1/1 Subdevice #0: subdevice #0 d# hwinfo --sound 21: PCI 1f.3: 0403 Audio device [Created at pci.378] Unique ID: nS1_.WnojYJLVCm0 SysFS ID: /devices/pci0000:00/0000:00:1f.3 SysFS BusID: 0000:00:1f.3 Hardware Class: sound Model: "Intel Audio device" Vendor: pci 0x8086 "Intel Corporation" Device: pci 0xa348 SubVendor: pci 0x1043 "ASUSTeK Computer Inc."
