With the auto-parser we can choose the dac nid for vmaster from
the DACs we already know, instead of hard-coding it. This is more
future-proof and was actually wrong on one machine.

Unfortunately this doesn't work correctly for some codecs.
Codecs like ALC262 have no volume in DAC (e.g. 0x02) but only in mixer
(e.g. 0x0c).
In future, we should build up the I/O paths like in patch_via.c,
so that such info can be checked more easily.
thanks,
Takashi

Ah, of course. Thanks for spotting. I believe the patch should look like
the attached one instead, what do you think?

The check of cfg->line_outs can be skipped. The primary output must
be present in any case. Or, at most, just add a non-zero check for
cfg->line_out_pins[0]. Otherwise it looks good.
Thanks!

Yeah, I was thinking that too, but then patch_alc662 had the no-hp
fixup, and with all fixups moving here and there, I decided to better be
safe than sorry. But I trust you to know better than me, so attaching
modified patch. :-)

Subject: [PATCH] ALSA: HDA: Realtek: Take vmaster dac from multiout dac list
With the auto-parser we can choose the dac nid for vmaster from
the DACs we already know, instead of hard-coding it. This is more
future-proof and was actually wrong on one machine.

Well, I found that the arguments for alc_look_for_out_vol_nid() are
swapped: they should be codec, pin, dac. I fixed it manually and
committed now with a slight coding-style fix.
