Public bug reported: No sound device detected during boot.
Searching for the problem showed that the sound card is not working. When searching for packages, I found an update Unpacking firmware-sof-signed (2.0-1ubuntu4.6) over (2.0-1ubuntu4.5) dated 2024-03-16 08:10:06. Replacing the firmware-sof-signed package from 2.0-1ubuntu4.6 to 2.0-1ubuntu2 resulted in the sound returning. lspci -vv -s 00:1f.3 00:1f.3 Multimedia audio controller: Intel Corporation Comet Lake PCH cAVS Subsystem: Dell Comet Lake PCH cAVS 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: 64 Interrupt: pin A routed to IRQ 159 Region 0: Memory at 6001b18000 (64-bit, non-prefetchable) [size=16K] Region 4: Memory at 6001a00000 (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: 00000000fee006d8 Data: 0000 Kernel driver in use: sof-audio-pci-intel-cnl Kernel modules: snd_hda_intel, snd_sof_pci_intel_cnl ** Affects: firmware-sof (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to firmware-sof in Ubuntu. https://bugs.launchpad.net/bugs/2058150 Title: version 2.0-1ubuntu4.6 not work sound card Status in firmware-sof package in Ubuntu: New Bug description: No sound device detected during boot.
