** Description changed: I am running Linux Mint 22.2 with a Comet Lake PCH-LP cAVS chipset. My analog audio ports are not detected; I only have a 'Dummy Output'. I have tried installing firmware-sof-signed, using dmic_detect=0, dsp_driver=1, and various model= options in alsa-base.conf. None have worked. The analog codec (Realtek, likely ALC2xx) is simply not showing up in aplay -l. It seems the problem lies with the specific motherboard not exposing the correct identification codes (Vendor/Subsystem ID) to the Linux kernel. + The sound stopped working after an update about 2 months ago. + Here is the diagnostic data: bahanet@tars:~$ inxi -Fxzd System: - Kernel: 6.14.0-35-generic arch: x86_64 bits: 64 compiler: gcc v: 13.3.0 - Desktop: Cinnamon v: 6.4.8 Distro: Linux Mint 22.2 Zara - base: Ubuntu 24.04 noble + Kernel: 6.14.0-35-generic arch: x86_64 bits: 64 compiler: gcc v: 13.3.0 + Desktop: Cinnamon v: 6.4.8 Distro: Linux Mint 22.2 Zara + base: Ubuntu 24.04 noble Machine: - Type: Desktop Mobo: N/A model: N/A serial: <superuser required> - BIOS: American Megatrends v: 5.17 date: 07/13/2020 + Type: Desktop Mobo: N/A model: N/A serial: <superuser required> + BIOS: American Megatrends v: 5.17 date: 07/13/2020 CPU: - Info: 6-core model: Intel Core i7-10710U bits: 64 type: MT MCP - arch: Comet Lake rev: 0 cache: L1: 384 KiB L2: 1.5 MiB L3: 12 MiB - Speed (MHz): avg: 607 high: 900 min/max: 400/4700 cores: 1: 900 2: 900 - 3: 900 4: 400 5: 900 6: 400 7: 400 8: 400 9: 400 10: 400 11: 887 12: 400 - bogomips: 38399 - Flags: avx avx2 ht lm nx pae sse sse2 sse3 sse4_1 sse4_2 ssse3 vmx + Info: 6-core model: Intel Core i7-10710U bits: 64 type: MT MCP + arch: Comet Lake rev: 0 cache: L1: 384 KiB L2: 1.5 MiB L3: 12 MiB + Speed (MHz): avg: 607 high: 900 min/max: 400/4700 cores: 1: 900 2: 900 + 3: 900 4: 400 5: 900 6: 400 7: 400 8: 400 9: 400 10: 400 11: 887 12: 400 + bogomips: 38399 + Flags: avx avx2 ht lm nx pae sse sse2 sse3 sse4_1 sse4_2 ssse3 vmx Graphics: - Device-1: Intel Comet Lake UHD Graphics driver: i915 v: kernel arch: Gen-9.5 - bus-ID: 00:02.0 - Display: x11 server: X.Org v: 21.1.11 with: Xwayland v: 23.2.6 driver: X: - loaded: modesetting unloaded: fbdev,vesa dri: iris gpu: i915 resolution: - 1: 2100x3360~60Hz 2: 3840x2400~60Hz 3: 3000x2000~60Hz - API: EGL v: 1.5 drivers: iris,swrast platforms: - active: gbm,x11,surfaceless,device inactive: wayland - API: OpenGL v: 4.6 compat-v: 4.5 vendor: intel mesa - v: 25.0.7-0ubuntu0.24.04.2 glx-v: 1.4 direct-render: yes renderer: Mesa - Intel UHD Graphics (CML GT2) + Device-1: Intel Comet Lake UHD Graphics driver: i915 v: kernel arch: Gen-9.5 + bus-ID: 00:02.0 + Display: x11 server: X.Org v: 21.1.11 with: Xwayland v: 23.2.6 driver: X: + loaded: modesetting unloaded: fbdev,vesa dri: iris gpu: i915 resolution: + 1: 2100x3360~60Hz 2: 3840x2400~60Hz 3: 3000x2000~60Hz + API: EGL v: 1.5 drivers: iris,swrast platforms: + active: gbm,x11,surfaceless,device inactive: wayland + API: OpenGL v: 4.6 compat-v: 4.5 vendor: intel mesa + v: 25.0.7-0ubuntu0.24.04.2 glx-v: 1.4 direct-render: yes renderer: Mesa + Intel UHD Graphics (CML GT2) Audio: - Device-1: Intel Comet Lake PCH-LP cAVS driver: snd_hda_intel v: kernel - bus-ID: 00:1f.3 - API: ALSA v: k6.14.0-35-generic status: kernel-api - Server-1: PipeWire v: 1.0.5 status: active - Server-2: PulseAudio v: 16.1 status: off (using pipewire-pulse) + Device-1: Intel Comet Lake PCH-LP cAVS driver: snd_hda_intel v: kernel + bus-ID: 00:1f.3 + API: ALSA v: k6.14.0-35-generic status: kernel-api + Server-1: PipeWire v: 1.0.5 status: active + Server-2: PulseAudio v: 16.1 status: off (using pipewire-pulse) Network: - Device-1: Realtek RTL8111/8168/8211/8411 PCI Express Gigabit Ethernet - driver: r8169 v: kernel port: 3000 bus-ID: 01:00.0 - IF: enp1s0 state: down mac: <filter> - Device-2: Intel Wi-Fi 6 AX200 driver: iwlwifi v: kernel bus-ID: 03:00.0 - IF: wlp3s0 state: up mac: <filter> - Device-3: ASIX AX88179 Gigabit Ethernet driver: ax88179_178a type: USB - bus-ID: 1-6.1:4 - IF: enx0023561c4841 state: down mac: <filter> + Device-1: Realtek RTL8111/8168/8211/8411 PCI Express Gigabit Ethernet + driver: r8169 v: kernel port: 3000 bus-ID: 01:00.0 + IF: enp1s0 state: down mac: <filter> + Device-2: Intel Wi-Fi 6 AX200 driver: iwlwifi v: kernel bus-ID: 03:00.0 + IF: wlp3s0 state: up mac: <filter> + Device-3: ASIX AX88179 Gigabit Ethernet driver: ax88179_178a type: USB + bus-ID: 1-6.1:4 + IF: enx0023561c4841 state: down mac: <filter> Bluetooth: - Device-1: Intel AX200 Bluetooth driver: btusb v: 0.8 type: USB bus-ID: 1-8:3 - Report: hciconfig ID: hci0 rfk-id: 0 state: down - bt-service: enabled,running rfk-block: hardware: no software: yes - address: <filter> + Device-1: Intel AX200 Bluetooth driver: btusb v: 0.8 type: USB bus-ID: 1-8:3 + Report: hciconfig ID: hci0 rfk-id: 0 state: down + bt-service: enabled,running rfk-block: hardware: no software: yes + address: <filter> Drives: - Local Storage: total: 953.87 GiB used: 33.72 GiB (3.5%) - ID-1: /dev/nvme0n1 vendor: Samsung model: MZVLB1T0HBLR-000L2 - size: 953.87 GiB temp: 49.9 C - Message: No optical or floppy data found. + Local Storage: total: 953.87 GiB used: 33.72 GiB (3.5%) + ID-1: /dev/nvme0n1 vendor: Samsung model: MZVLB1T0HBLR-000L2 + size: 953.87 GiB temp: 49.9 C + Message: No optical or floppy data found.
