Hi all, sorry if I put somebody in CC who is not the correct one. I have a google pixelbook and using it with Fedora 37. The last few kernels supplied by fedora 37, 6.1.6, 6.1.7 but also some earlier have no working sound. I see the last kernel for me with working sound is 6.0.18. On my pixelbook this is showing in dmesg: [ 7.623064] snd_soc_skl 0000:00:1f.3: ASoC: no sink widget found for AEC Capture [ 7.623070] snd_soc_skl 0000:00:1f.3: ASoC: Failed to add route echo_ref_out cpr 7 -> direct -> AEC Capture [ 7.623083] kbl_r5514_5663_max kbl_r5514_5663_max: ASoC: Parent card not yet available, widget card binding deferred [ 8.090716] NET: Registered PF_QIPCRTR protocol family [ 8.273905] rt5663 i2c-10EC5663:00: sysclk < 384 x fs, disable i2s asrc [ 8.275043] HDMI HDA Codec ehdaudio0D2: hdac_hdmi_present_sense: disconnect for pin:port 5:0 [ 8.275165] HDMI HDA Codec ehdaudio0D2: hdac_hdmi_present_sense: disconnect for pin:port 6:0 [ 8.275291] HDMI HDA Codec ehdaudio0D2: hdac_hdmi_present_sense: disconnect for pin:port 7:0 [ 8.278569] input: kbl-r5514-5663-max Headset Jack as /devices/platform/kbl_r5514_5663_max/sound/card0/input30 [ 8.278771] input: kbl-r5514-5663-max HDMI/DP,pcm=6 Jack as /devices/platform/kbl_r5514_5663_max/sound/card0/input31 [ 8.278875] input: kbl-r5514-5663-max HDMI/DP,pcm=7 Jack as /devices/platform/kbl_r5514_5663_max/sound/card0/input32 [ 8.891244] iwlwifi 0000:01:00.0: Applying debug destination EXTERNAL_DRAM [ 8.902009] r8152 2-2.1:1.0 enp0s20f0u2u1: carrier on [ 8.977070] iwlwifi 0000:01:00.0: Applying debug destination EXTERNAL_DRAM [ 8.978496] iwlwifi 0000:01:00.0: FW already configured (0) - re-configuring [ 8.991112] IPv6: ADDRCONF(NETDEV_CHANGE): enp0s20f0u2u1: link becomes ready [ 9.027053] iwlwifi 0000:01:00.0: Applying debug destination EXTERNAL_DRAM [ 9.112264] iwlwifi 0000:01:00.0: Applying debug destination EXTERNAL_DRAM [ 9.113562] iwlwifi 0000:01:00.0: FW already configured (0) - re-configuring [ 14.579846] HDMI HDA Codec ehdaudio0D2: No connections found for pin:port 5:0 Can please somebody help with this issue ? Also in the latests kernels the shutdown stops and the machine does not halt. It stays forever waiting for something to happen it seems. If you need more details please dont hesitate to contact me. And please CC me as I am not subscribed in these miling lists. Rgds Sasa
