Can we do something else than turning off the power-save codec settings to avoid such noises? I have this question because it's > really easy to disable something, but I feel that the culprit of the noises might be just the wrong codec settings. I guess that you have probably full documentation for the codec and probably for the > hardware, so it might be nice to find the real culprit. Note that power_save_node=0 doesn't mean that the whole power saving is disabled. It disables the fine-grained power saving, i.e. powering down the unused widget nodes. If so, I wonder whether this might be about the default pin-shutup behavior. I improved the click noise problem on my Dell desktop by disabling the pin shutup. See commit c0ca5eced222. Kailang, Hui, did you try to add the chain to ALC269_FIXUP_NO_SHUTUP? thanks, Takashi _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx https://mailman.alsa-project.org/mailman/listinfo/alsa-devel
