Easy things to test are GPIO bits. Run hda-verb like
hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_MASK 0x0f hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DATA 0x0f or hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DIR 0x0f hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DATA 0x0f
etc. CS4206 seems to have 4 GPIO lines, and each bit (0-3) corresponds to each GPIO. In many case, GPIO0 or GPIO1 corresponds to the amplifier (EAPD) bit. Define the GPIO direction of each GPIO bit by SET_GPIO_DIR, and turn on/off the GPIO bits by SET_GPIO_DATA. Running hda-verb /dev/snd/hwC0D0 0x01 GET_GPIO_DATA 0 will show the current GPIO data bits. Or you can check it in codec#* proc file.

takashi, thank you _so_ much!
after running all 4 of those:
hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_MASK 0x0f hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DATA 0x0f or hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DIR 0x0f hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DATA 0x0f
i suddendly had sound!! :D :D :D :D :D :D :D only via speakers though - there is no sound via headphones right now.
mixer channels:
- Master (with Mutebutton), PCM and Front (also with Mute) all work =)
- i don't know what surround would do (or it's extra switch)
- headphones-volumes and mute button don't affect the speakers, which is good
=)
is there a way to reset what i did with hda-verb, so that i can figure out which combination it was exactly?
You can just change the value 0x0f to a different value. At least, you can try commands like hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DATA 0x01 hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DATA 0x02 hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DATA 0x04 hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DATA 0x08 and check the speaker output at each time. Also, check the GPIO direction, hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DIR 0x01 hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DATA 0x01 hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DIR 0x02 hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DATA 0x02 ...
Regarding the headphone: is the speaker muted when you plug in the headphone? If not, it's likely an issue of the jack detection. If the speaker is muted but no headphone output, it's a missing initialization (or wrong GPIO setup).
Setting both _DIR and _DATA to 0x08 worked, as did 0x0f.
OK, then GPIO2 is EAPD.
Plugging in headphones does not mute the speaker.
I'll check this later.
thanks,
Takashi
