Did you try my suggestion of having the CODEC driver do whatever
is triggered by disabling the jack on suspend?  That should just
be simple code motion shouldn't it, not something that requires
extensive investigation?

On the other hand if we're getting the same bodge done repeatedly
in a lot of machines that suggests it's something we should stop
spreading...

There was also the issue with automatically muting the speaker
when headphones are inserted which will affect UCM files.
