Is there a way to initialize mixer elements?

Is there a way to initialize mixer elements?

[Ozan Çağlayan]

Hi,

Sometimes specific hardwares needs special tweaks (e.g. a mixer element
is muted by default which avoids getting sound from HP, or the master
volume's gain is very low, etc.). Do we have some kind of quirks
(kernel-space/user-space) for that situations?

As a real-world example, I have a user with a VIA VT1708B codec which is
not able to get sound from HP unless he mutes the 'Independent HP' control:

Well, "alsactl init" should be responsible for such a thing.

Is the switch turned on as default?  I think it should be rather off.
