Hi Paul > do you still have the problem *without* `dsp_driver=0` on an up-to- date Ubuntu 19.10 with Linux 5.5-rc6?
I just tried the 5.5 release https://kernel.ubuntu.com/~kernel- ppa/mainline/v5.5/ I also tried newest 1.4.2 from sof project and updadted their github issue. The trick with dsp_driver=0 seems not to work anymore. I resorted to adding "snd_hda_intel.dmic_detect=0" to GRUB_CMDLINE_LINUX_DEFAULT as suggested at Red Hat link you posted and will get the snd_hda_intel driver: [ 151.393221] snd_hda_intel 0000:00:1f.3: dmic_detect option is deprecated, pass snd-intel-dspcfg.dsp_driver=1 option instead [ 151.393257] snd_hda_intel 0000:00:1f.3: enabling device (0000 -> 0002) [ 151.393565] snd_hda_intel 0000:00:1f.3: bound 0000:00:02.0 (ops i915_audio_component_bind_ops [i915]) [ 151.403720] thermal thermal_zone9: failed to read out thermal zone (-61) [ 151.405115] iwlwifi 0000:00:14.3 wlp0s20f3: renamed from wlan0 [ 151.435143] snd_hda_codec_generic hdaudioC0D0: autoconfig for Generic: line_outs=1 (0x17/0x0/0x0/0x0/0x0) type:speaker [ 151.435144] snd_hda_codec_generic hdaudioC0D0: speaker_outs=0 (0x0/0x0/0x0/0x0/0x0) [ 151.435145] snd_hda_codec_generic hdaudioC0D0: hp_outs=1 (0x16/0x0/0x0/0x0/0x0) [ 151.435146] snd_hda_codec_generic hdaudioC0D0: mono: mono_out=0x0 [ 151.435146] snd_hda_codec_generic hdaudioC0D0: inputs: [ 151.435147] snd_hda_codec_generic hdaudioC0D0: Mic=0x19 That works well for me now. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1856366 Title: PCI/internal sound card not detected on a Swift SF314-57 Status in alsa-driver package in Ubuntu: New Bug description: No sound card detected with kernel 5.5.0-050500rc1-generic 1.
