Maybe the device is now supported by SOF driver and you didn't enable the driver or miss the firmware / topology files. If you need to use the legacy driver, passing snd_hda_intel.dmic_detect=0 option should work. Created attachment 286653 [details]
dmesg
search for dmic_detect or sof-audio-pci to find the relevant error messages.
Sorry for double-posting. I seem to have the same issue. My laptop is a `HP Spectre x360 df0709nz`. It worked on kernel 5.3.x. `alsa-info.sh` gave me the device ID: `00:1f.3 0401: 8086:9dc8 (rev 30) Subsystem: 103c:8518` On kernel `5.4.7-200.fc31.x86_64`, the sound card is not detected. See dmesg, search for `sof-audio-pci` for the relevant errors. Adding kernel parameter `snd_hda_intel.dmic_detect=0` didn't help. I got this error in dmesg: `snd_hda_intel: unknown parameter 'dmic_detect' ignored`. How can I try SOF drivers? The dmic_detect parameter was removed from snd_hda_intel and replaced by "snd-intel-dspcfg.dsp_driver=1" kernel parameter in the latest kernel code. echo "options snd-intel-dspcfg dsp_driver=1" > /etc/modprobe.d/alsa.conf @Jaroslav Kysela: Thanks. Sound and mic work again. Editing /etc/modprobe.d/alsa.conf made sound work again on my ThinkPad X1 Carbon 7, but now the top-firing speakers don't work, only the rear ones do. All of the speakers worked fine on 5.3.x. On kernel `5.4.10-200.fc31.x86_64`, the workaround is not necessary anymore to get sound. However, the Laptop's mic isn't working. (Headphone mic works.) ❯ sudo lspci -vnvn | grep audio -A16 00:1f.3 Multimedia audio controller [0401]: Intel Corporation Cannon Point-LP High Definition Audio Controller [8086:9dc8] (rev 30) Subsystem: Hewlett-Packard Company Device [103c:8518] Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx+ Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 32, Cache Line Size: 64 bytes Interrupt: pin A routed to IRQ 183 Region 0: Memory at 6043118000 (64-bit, non-prefetchable) [size=16K] Region 4: Memory at 6043000000 (64-bit, non-prefetchable) [size=1M] Capabilities: [50] Power Management version 3 Flags: PMEClk- DSI- D1- D2- AuxCurrent=55mA PME(D0-,D1-,D2-,D3hot+,D3cold+) Status: D0 NoSoftRst+ PME-Enable- DSel=0 DScale=0 PME- Capabilities: [80] Vendor Specific Information: Len=14 <?> Capabilities: [60] MSI: Enable+ Count=1/1 Maskable- 64bit+ Address: 00000000fee00838 Data: 0000 Kernel driver in use: snd_hda_intel Kernel modules: snd_hda_intel, snd_soc_skl On kernel `5.5.5-200.fc31.x86_64`, the problem reappeared and can be fixed with the same workaround. (`echo "options snd-intel-dspcfg dsp_driver=1" > /etc/modprobe.d/alsa.conf`) The long term goal is to enable the SOF driver by default.

Created attachment 286423 [details] lspci-vnvn I have a HP Spectre x360 15-df0006nl. Audio was working on Linux Kernel 5.3.18. After update on 5.4 (I've tried 5.4.5 and 5.4.6) audio doesn't work. I can't see any devices in alsamixer. This is my OS version: Linux version 5.4.6-050406-generic (kernel@kathleen) (gcc version 9.2.1 20191130 (Ubuntu 9.2.1-21ubuntu1)) #201912211140 SMP Sat Dec 21 11:43:01 UTC 2019 Let me know if I have to submit more information. I attach lspci-vnvn log.
