Log file (dmesg) - initial boot and after warm boot
Just to clarify, in the last two lines after warm reboot: [ 9.594956] hdaudio hdaudioC1D0: no AFG or MFG node found [ 9.594965] snd_hda_intel 0000:03:00.6: no codecs initialized Could you run alsa-info.sh to dump codec info? Please do ==> echo 1 > /sys/module/snd_hda_codec/parameters/dump_coef before do alsa-info.sh. Created attachment 308121 [details]

Added alsa-info outputs: 1. the original code with the regression (kernel v6.14, standard with Ubuntu 25.04) 2. the reverted change (kernel v6.15rc5, compiled) Kailiang, I added alsa-info outputs to https://bugzilla.kernel.org/show_bug.cgi?id=220109 (see attachments for both the regression and reverted changes) by following your instructions. Please let me know if there is any other information you need.
