So, we need to disable the widgets power control in patch_via.c completely as a quick workaround. Could you check whether the patch below is OK (except for the possible headphone mute issue)?
Well... It seems that something went unnoticed. This command seems to be essential for this (and the revised) patch to get the headphone output at all:
hda-verb /dev/snd/hwC0D0 0x25 SET_PIN_WID 0xc0
I also used to run the other command after unplugging and re-plugging (without it, the headphone is muted after re-plugging):
hda-verb /dev/snd/hwC0D0 0x25 SET_EAPD 0x02
But running
hda-verb /dev/snd/hwC0D0 0x24 SET_EAPD 0x03
also helps to restore the headphone output after re-plugging.
Regarding the headphone mute: after confirming the headphone itself is working with the patch, please give alsa-info.sh outputs again with and without the headphone plug.
Attached.
Then, at the headphone plugged (and the speaker is still audible wrongly), take a look at /proc/asound/card0/codec#0 file. Look for "Node 0x24", and check whether Pin-ctls item shows 0x00.
It does. And there is no output from the speakers.
In the former case (0x00), try to run like:
hda-verb /dev/snd/hwC0D0 0x24 SET_EAPD 0x01
Does it mute the speaker? If not, make it back via
The speaker is muted with this patch, when I plug the headphone.
hda-verb /dev/snd/hwC0D0 0x24 SET_EAPD 0x03
And this command will turn it on, but only if I also activate "Independent Headphone".
then turn to D3 via
hda-verb /dev/snd/hwC0D0 0x24 SET_POWER 0x03
Does this mute? In return, after unplug, it may still be muted.
These command seem to have no effect at all.
