You passed a wrong option. The option is for snd_hda_codec module. So either create a modprobe.d/*.conf file containing: options snd_hda_codec dump_coef=1 or pass snd_hda_codec.dump_coef=1 at boot cmdline option. BTW, it'd be better to get the outputs with --no-upload option of alsa-info.sh, and attach them. Last but not least, please don't drop Cc to ML unless you need to do so. thanks, Takashi _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx https://mailman.alsa-project.org/mailman/listinfo/alsa-devel
