From: Derek Fang derek.fang@realtek.com

When the system plays a sound immediately after resuming from S3, it could hear a little pop from headphones. It is due to the HP was unmuted before the completion of jack re-detection finished in parallel.

This patch adds a lock to make sure the HP unmute after jack detect handler, and adds a few depop changes.
