Hi, I tested in the HP laptop model we have here. The patch works very well, I 
only noticed two things:

- The PCM slider in alsamixer doesn't have any effect on volume, Master slide 
- In HP laptop model here Docking Mic binds to the external mic and Internal 
Mic to the builtin mic (it's the only two items in this laptop, External Mic 
doesn't really exist, I can create another model only for the laptop here to 
omit External Mic and rename Docking Mic to External Mic, but it's not 
something important anyway). I noticed just something strange in the automute 
of the mic inputs: if the volume is not zero for Docking Mic, it doesn't 
automute Internal Mic, I can capture from both inputs, but if I mute Docking 
Mic (=0), and plug the mic in Docking Mic, it mutes Internal Mic.

I tested other things like Headphone automute and it's ok. Thanks to all.
