Comment 116 for bug 1653456

@FZ - For me, the headphone jack fix works entirely correctly. The rear speakers are muted when headphones are connected, and un-muted when the headphones are disconnected. Unless that's an issue with the new BIOS (I haven't tried it) then perhaps it would be worth having another tinker with hdajackretask?

@aljosa - I'd be surprised if heating on the right side of the laptop could be caused by a misidentified headphone jack. In benchmarks, there is a slightly warmer area to the right of the touchpad, which seems to correspond to the location of the HDD. However, the laptop is supposed to have excellent cooling (certainly this has been my experience) so if any part of the laptop goes much above 40-45C it might indicate a hardware fault. But first maybe just check if you're thrashing the HDD...

Still hoping for a solution to the trackpad problem! Even once Ubuntu 17.10 is released it'd be quite annoying to have to suspend/resume the laptop every time.
