Try to disable the "automute" control that you see in Alsamixer: use right arrow arrow key to move to this control, then down arrow key to disable "automute": your speaker should now be independent from headphone jack, and only controlled by the "speaker" fader (mute it).

I think the problem has gone away now. At least it has not surfaced since last 5 restarts. It was solved by a combination of steps mentioned in the question and restarting at each step.

Unless your hardware has a direct monitoring feature and can completely avoid processing the sound through software, there is going to be latency.
