It worked for playback, but completely broke recording. I've missed that
your CODEC does not support input switching in hardware, while driver
does not support that in software. For playback software switching is
supported by the driver, so it worked. Patch below should give you
automatic switching on playback, but still two separate recording devices.

It tells the driver that those two inputs should be parts of one output
device, and driver following HDA specifications reads jack presence
information from respective CODEC pins. Sound actually played to both
outputs, but driver mutes one of them, depending on jack presence.

Lenovo engineers configured the CODEC to report each pin as separate
audio device, but the problem that our sound(4) does not support
automatic switching between them. :(
