I just noticed (use the headphones rarely) that the headphones on this System76 Lemur Ultra (lemu4) stopped working. There is absolutely no output.
It's strange that the pin 0x25 shows EAPD 0x00 and pin-control 0x00. They should be 0x02 and 0xc0 constantly. Is it taken at the moment the headphone is plugged, right? Please give alsa-info.sh outputs at both the headphone plugged and unplugged.
Attached. Sorry for gzipping, the alsa-devel rejects two at a time: too large.
Could you check whether changing them makes the headphone output working? For example, get hda-verb program (see Documentation/sound/alsa/HD-Audio.txt) and run it like
hda-verb /dev/snd/hwC0D0 0x25 SET_PIN_WID 0xc0 hda-verb /dev/snd/hwC0D0 0x25 SET_EAPD 0x02It helps, headphones start working.
Also, what happens if you apply the patch below?
spec->set_widgets_power_state = set_widgets_power_state_vt2002P;
//spec->set_widgets_power_state = set_widgets_power_state_vt2002P;This helps as well. Yay! Thanks :) Whatever the outcome, I have them back more or less (more, for me) properly.
OK, then we know the place to fix now. Try the patch below instead. Does it fix the problem as well?
The below is the revised patch, fixing not only for VT1802 but other VIA codecs, too. Please let me know if it works.
thanks,
Takashi
--- From: Takashi Iwai tiwai@suse.de Subject: [PATCH] ALSA: hda - Fix wrong power setup for HP paths of VIA codecs
The set_widgets_power_state_*() callbacks in patch_via.c are converted to evaluate spec->gen.indep_hp_enabled when the codec parser was switched to use the generic parser. However, the generic parser takes the headphone paths in a different way as the original VIA parser; it tries the paths with individual DACs as much as possible. This ended up with the incorrect check of the power status in the HP paths, resulting in the silent output from the headphones.
This patch removes the invalid check of indep_hp_enabled flag and sets the proper power status for those paths.
