It's not well known to the driver, and that's the problem.
Your BIOS misinforms that there are 4 line-out jacks are available.
Thus the driver thinks that no jack retasking is needed, as you have
already the full set of line outs.

You can fix it by overriding the default pin configuration via patch
option.  Specifically, you'd need to disable the unused line out pins
like 0x15, 0x16 and 0x17.
