Hah! I managed it!!! Just tested with speaker-test, so far. I hacked the
driver a bit:
In patch_analog.c in static int patch_ad1986a(struct hda_codec *codec)
case AD1986A_3STACK:
spec->num_mixers = 2;
spec->mixers[1] = ad1986a_3st_mixers;
//spec->num_init_verbs = 3;
//spec->init_verbs[1] = ad1986a_3st_init_verbs;
//spec->init_verbs[2] = ad1986a_ch2_init;
spec->channel_mode = ad1986a_modes;
spec->num_channel_mode = ARRAY_SIZE(ad1986a_modes);
spec->need_dac_fix = 0;//1;
spec->multiout.max_channels = 6;//2;
spec->multiout.num_dacs = 3;//1;
break;
I don't yet know whether it is completely correct what I did and what is the
minimal change needed.
Perhaps some of the changes will lead to regressions, I need to check further.
I think setting max channels and num_dacs has nor meaning, as probably the get
overwritten on ch set, right? dac_fix probably changes the way num_dacs are
assigned to?
So my guess is that probably setting ad1986a_3st_init_verbs is wrong for my
mobo.
{0x0f, AC_VERB_SET_CONNECT_SEL, 0x2},
{0x10, AC_VERB_SET_CONNECT_SEL, 0x1},
What do those magic number 0x1 and 0x2 mean here? I looked into hda specs and
ad1986a specs. 0xf is mic selector and 0x10 is line selector. Does is select
which physical output is chosen?
I will test later whether leaking dac_fix as 1 and ust taking out
ad1986a_3st_init_verbs will be enough.
Cheers,
