Hi Hui, thanks I was already experimenting with sof-icl.ri from the sof project. I also compiled and tested my own version. When I put the file you provided and then modprobe for snd_sof_pci then I get the following dmesg:
[ 1220.050239] HDMI HDA Codec ehdaudio0D2: Max dais supported: 3 [ 1221.652307] sof-audio-pci 0000:00:1f.3: error: cl_copy_fw: timeout HDA_DSP_SRAM_REG_ROM_STATUS read [ 1221.652890] sof-audio-pci 0000:00:1f.3: error: load fw failed ret: -110 [ 1221.652955] sof-audio-pci 0000:00:1f.3: error: status = 0x0000002c panic = 0x00000000 [ 1221.652978] sof-audio-pci 0000:00:1f.3: error: failed to reset DSP [ 1221.652981] sof-audio-pci 0000:00:1f.3: error: failed to boot DSP firmware -110 [ 1221.652984] sof-audio-pci 0000:00:1f.3: error: sof_probe_work failed err: -110 I see in lsmod it got loaded, but no sound cards. I also compiled my own version of sof-pci-dev.ko using linux-5.5-rc1. What is strange I had to compile it with EXTRAVERSION="-050500rc1-generic SMP mod_unload" for insmod to accept it. The compiled driver also did not help to find any sound card. I will try now with "options snd-hda-intel dsp_driver=0" -- 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
