Hi Paul, > does the pre-built firmware file from https://github.com/thesofproject/sof/releases work?
I tried the releases 1.4.1 and 1.3 as well as followed their instractions to build from latest soource. The sof-icl.ri did not work for me with 5.5-rc1 and 5.4. I did not check for 5.3 because my sound card (Intel Corporation Device [8086:34c8]) was working well already with the snd_hda_intel module. > 2. With the firmware file installed, does Linux 5.3 work with `dsp_driver=0`? Yes. Without and with that option 5.3 will load snd_hda_intel for the sound card. > Please attach the Linux messages from the non-working and working boot. Find attached the outputs. I think the interesting bit is in the not working boot: sof-audio-pci 0000:00:1f.3: DSP detected with PCI class/subclass/prog-if info 0x040100 sof-audio-pci 0000:00:1f.3: Digital mics found on Skylake+ platform, using SOF driver sof-audio-pci 0000:00:1f.3: enabling device (0000 -> 0002) sof-audio-pci 0000:00:1f.3: warning: No matching ASoC machine driver found sof-audio-pci 0000:00:1f.3: DSP detected with PCI class/subclass/prog-if 0x040100 sof-audio-pci 0000:00:1f.3: use msi interrupt mode sof-audio-pci 0000:00:1f.3: bound 0000:00:02.0 (ops i915_audio_component_bind_ops [i915 > you should also install the other firmware files like for graphics. I have linux-firmware installed. The video looks good for now, so I will ignore that issue :| ** Attachment added: "dmesg_linux.tar" https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1856366/+attachment/5312385/+files/dmesg_linux.tar -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1856366 Title: PCI/internal sound card not detected To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1856366/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
