Sure thing,
Kailang, yes, there is a side headphones jack and it does work OK
after PM suspend-to-ram
I did `echo 1 > /sys/modules/snd_hda_codec/parameters/dump_coef ` and
I attached the output but you are probably interested in this:
Node 0x20 [Vendor Defined Widget] wcaps 0xf00040: Mono
.....
447c447
< Coeff 0x1f: 0x00c0
---
> Coeff 0x1f: 0x0000
464c464
< Coeff 0x30: 0x00b1
---
> Coeff 0x30: 0x0090
And after I reset the two processing caps, the sound is back again.
hda-verb /dev/snd/hwC0D0 0x20 SET_COEF_INDEX 0x1f
hda-verb /dev/snd/hwC0D0 0x20 SET_PROC_COEF 0x00c0
hda-verb /dev/snd/hwC0D0 0x20 SET_COEF_INDEX 0x30
hda-verb /dev/snd/hwC0D0 0x20 SET_PROC_COEF 0x00b1
I'm not sure that this are the correct parameters of hda-verb (because
I lack the knowledge of alsa development) but based on the result it
seems to be correct
Takashi, thanks for the hint
