ASUS EeePC 1001px has strange variant of ALC269 CODEC, that mutes speaker

Browse Source 
if unused in that configuration mixer at NID 15 is muted.  Probably CODEC
incorrectly reports its internal connections.  Hide that muter from the
driver to avoid muting and make built-in speaker work.

There are several different CODECs sharing this ID and I have not enough
information about them and the bug to implement more universal solution.
