It references another Linux variant (eww). But, reading their thread you will find that they made a patch in December 2018 to solve the 294 issue. Then, the bug report for Ubuntu let to y'all doing the same. I've done all the same steps mentioned in both threads. It appears that the same patch is needed for ACL274. Post 28 from December 2018, https://forum.manjaro.org/t/alc294-analog- audio-card-detected-but-no-sound-internaly-or-headphones/54089/28, states: "each one of ASUS new laptop models with Realtek ALC294 have individual hwinfo SubVendor and SubDevice values. They are needed for QUIRK hack directly in /sound/pci/hda/patch_realtek.c file." Additionally, it includes 3 patches for the kernel regarding realtek.c. This makes sense since all other methods to resolve fail. So, what commands should I run to get you all that data to solve this matter? :-) -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1821936 Title: ALC274 unsupported Status in alsa-driver package in Ubuntu: Incomplete Status in linux package in Ubuntu: Incomplete Bug description: 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."
