Created attachment 308016 [details] patch_realtek.c patch My HP laptop is equipped with a 0x863E board which has a mute LED only, no micmute LEDs, and its ALC285 codec misses the front speakers, in contrast to similar other bug reports. Therefore, none of the existing quirks in sound/pci/hda/patch_realtek.c are entirely suitable. The attached combination enables all speakers and the LED on this board.
Thanks for the report and the patch. The code change looks OK at a quick glance. Would you submit your patch to the upstream for merging? Just put the patch description, your Signed-off-by tag, and set a subject with "ALSA: hda/realtek: ....", and submit to linux-sound@vger.kernel.org and put maintainer (me) to Cc. See Documentation/process/submitting-patches.rst for details. If you don't want to do it by yourself, I can pick up this and submit from my side, too.
Err, it may be better if you submit it. I never used git send-email before, and gmail PWA tends to scramble tab symbols which would break the patch. Thanks a lot!
OK, now submitted to the upstream: https://lore.kernel.org/20250427081035.11567-1-tiwai@suse.de
