OK, I was right. Taking out ad1986a_3st_init_verbs is enough for making it
work:
case AD1986A_3STACK:
spec->num_mixers = 2;
spec->mixers[1] = ad1986a_3st_mixers;
spec->num_init_verbs = 1;//2;
//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 = 1;
spec->multiout.max_channels = 2;
spec->multiout.num_dacs = 1;
break;
There is still one bug left for me: If I change ch setting, I need to adjust
vol for sur, cl/lfe again, otherwise they stay mute. Bug of driver or
alsamixer?
Would be nice if we got a real fix for kernel 2.6.21. :-)
Cheers,
