Michael, the ubuntustudio-plugins was a suggestion made by a reporter that sadly didn't help in the issue at hand and the problems caused by those plugins are not related to this bug at all.
Also the bug is related to Acer laptops, HDA-Nvidia and ALC268 codec. (maybe it can affect the HDA-Intel but not sure at this time)
digging around a bit i've found an upstream commit maybe related with this issue.

Maybe it's worth for the reporters affected to give it a try.
