Forgot to mention that the above is only for TP410/510.
For TP420 & co, the second one should be used.

Also, for TP410/510, the following values might be better (this time
contains 0x19, too):

0x19 0x042110ff
0x1a 0x21a190f0
0x1c 0x212140ff

This will make the built-in and the dock headphones as headphones.
The mixer elements will be more intuitive than the former version.


thanks,

Takashi
