I'm relatively new here, first time reporting a regression, so apologies in advance if I'm doing something wrong. I'm using Arch Linux (linux-mainline kernel) on my chromebook Acer Spin 713-2W (Voxel), and after upgrading linux-mainline from 6.7-rc4 to 6.7-rc5 the audio setup isn't working anymore. Firstly I suspected its some changes in the sof- firmware, yet got no luck in upgrading sof-firmware (2023.09.2 -> 2023.12). On certain chromebooks, audio setup needs custom ALSA ucm confs [1], but after contacting the chromebook-linux-audio developer [2], I think it's not a conf problem, but rather a kernel regression. After hours of bisecting, the first bad commit 31ed8da (ASoC: SOF: sof-audio: Modify logic for enabling/disabling topology cores) ensures the regression. demsg log pasted below: // before 31ed8da, working [ 61.572587] sof-audio-pci-intel-tgl 0000:00:1f.3: ipc tx error for 0x60010000 (msg/reply size: 108/20): -22 [ 61.572593] sof-audio-pci-intel-tgl 0000:00:1f.3: HW params ipc failed for stream 1 [ 61.572594] sof-audio-pci-intel-tgl 0000:00:1f.3: ASoC: error at snd_soc_pcm_component_hw_params on 0000:00:1f.3: -22 [ 61.573247] sof-audio-pci-intel-tgl 0000:00:1f.3: ipc tx error for 0x60010000 (msg/reply size: 108/20): -22 [ 61.573250] sof-audio-pci-intel-tgl 0000:00:1f.3: HW params ipc failed for stream 1 [ 61.573251] sof-audio-pci-intel-tgl 0000:00:1f.3: ASoC: error at snd_soc_pcm_component_hw_params on 0000:00:1f.3: -22 [ 61.573888] sof-audio-pci-intel-tgl 0000:00:1f.3: ipc tx error for 0x60010000 (msg/reply size: 108/20): -22 [ 61.573892] sof-audio-pci-intel-tgl 0000:00:1f.3: HW params ipc failed for stream 1 [ 61.573893] sof-audio-pci-intel-tgl 0000:00:1f.3: ASoC: error at snd_soc_pcm_component_hw_params on 0000:00:1f.3: -22 [ 61.574570] sof-audio-pci-intel-tgl 0000:00:1f.3: ipc tx error for 0x60010000 (msg/reply size: 108/20): -22 [ 61.574572] sof-audio-pci-intel-tgl 0000:00:1f.3: HW params ipc failed for stream 1 [ 61.574573] sof-audio-pci-intel-tgl 0000:00:1f.3: ASoC: error at snd_soc_pcm_component_hw_params on 0000:00:1f.3: -22 // after 31ed8da, broken [ 48.930740] sof-audio-pci-intel-tgl 0000:00:1f.3: ipc tx error for 0x30020000 (msg/reply size: 12/0): -13 [ 48.930762] sof-audio-pci-intel-tgl 0000:00:1f.3: failed to free widget DMIC0.IN [ 57.235697] sof-audio-pci-intel-tgl 0000:00:1f.3: ipc tx error for 0x30030000 (msg/reply size: 16/0): -22 [ 57.235701] sof-audio-pci-intel-tgl 0000:00:1f.3: sof_ipc3_route_setup: route DMIC0.IN -> BUF4.0 failed [ 57.235703] sof-audio-pci-intel-tgl 0000:00:1f.3: sof_ipc3_set_up_all_pipelines: route set up failed [ 57.235704] sof-audio-pci-intel-tgl 0000:00:1f.3: Failed to restore pipeline after resume -22 [ 57.235706] sof-audio-pci-intel-tgl 0000:00:1f.3: ASoC: error at snd_soc_pcm_component_pm_runtime_get on 0000:00:1f.3: -22 [ 57.235926] sof-audio-pci-intel-tgl 0000:00:1f.3: ASoC: error at snd_soc_pcm_component_pm_runtime_get on 0000:00:1f.3: -22 [ 57.235966] sof-audio-pci-intel-tgl 0000:00:1f.3: ASoC: error at snd_soc_pcm_component_pm_runtime_get on 0000:00:1f.3: -22 [ 57.236006] sof-audio-pci-intel-tgl 0000:00:1f.3: ASoC: error at snd_soc_pcm_component_pm_runtime_get on 0000:00:1f.3: -22 [ 57.236041] sof-audio-pci-intel-tgl 0000:00:1f.3: ASoC: error at snd_soc_pcm_component_pm_runtime_get on 0000:00:1f.3: -22 [ 57.236074] sof-audio-pci-intel-tgl 0000:00:1f.3: ASoC: error at snd_soc_pcm_component_pm_runtime_get on 0000:00:1f.3: -22 [ 57.236107] sof-audio-pci-intel-tgl 0000:00:1f.3: ASoC: error at snd_soc_pcm_component_pm_runtime_get on 0000:00:1f.3: -22 [ 57.236141] sof-audio-pci-intel-tgl 0000:00:1f.3: ASoC: error at snd_soc_pcm_component_pm_runtime_get on 0000:00:1f.3: -22 [ 57.236173] sof-audio-pci-intel-tgl 0000:00:1f.3: ASoC: error at snd_soc_pcm_component_pm_runtime_get on 0000:00:1f.3: -22 [ 57.236205] sof-audio-pci-intel-tgl 0000:00:1f.3: ASoC: error at snd_soc_pcm_component_pm_runtime_get on 0000:00:1f.3: -22 [ 57.236239] sof-audio-pci-intel-tgl 0000:00:1f.3: ASoC: error at snd_soc_pcm_component_pm_runtime_get on 0000:00:1f.3: -22 Steps to reproduce: - Run chromebook-linux-audio script [2] (this would install custom sof-rt5682 ucm confs [1] into /usr/share/alsa/ucm2/conf.d/sof-rt5682 and write a line `options snd-intel-dspcfg dsp_driver=3` to /etc/modprobe.d/snd-sof.conf) - Reboot, gets audio working on kernels before 31ed8da - Install latest stable kernel (6.7.3), audio broken - Install latest git kernel (6.8-rc2), audio broken - Revert 31ed8da, build upon latest linux-git (6.8-rc2), audio working Apologies for my busyiness that I should have reported it long before the regression enters stable and lts, but sadly linux-lts (6.6.13) seems to be affected too [3]. Please let me know if there's any other thing that I can help debugging. -- Mole Shang [1]: https://github.com/WeirdTreeThing/chromebook-ucm-conf/tree/main/sof-rt5682 [2]: https://github.com/WeirdTreeThing/chromebook-linux-audio/issues/70 [3]: https://github.com/WeirdTreeThing/chromebook-linux-audio/issues/ 70#issuecomment-1911048309 #regzbot introduced: 31ed8da1c8e5e504710bb36863700e3389f8fc81
