Thank you for your reply,

Please see below the output of alsa-info.sh before and after the 
headphone plugged in


I have 6 Jacks at the rear panel and two at the top (one output one input)
I am afraid I do not know how to switch channel mode to retask.

Also, the computer is of a certain age, and the issue has started 
several month ago but I never really looked into it, so I am not sure 
that change in power management will be relevant has it seems quite recent.

Looking forward for your reply,
