[nmglug] Really annoying beeps

Thank you Ted and Akkana.  Whenever my levels of Linux experience and 
imagination fail me and I receive a response to a nmglug question from 
either of you I always learn something new and useful.  Usually, more 
than one thing.

So I've been through everything both of you have mentioned and I've 
achieved partial success.  That is, I've identified three or four 
methods all of which appear to be functional with respect to turning 
off, or at least dramatically quieting, the intermittent instances of 
beeps associated with logging out.  I'll have to sift through my notes 
and recount these later when I have more time. Also there are a couple 
of fairly new Arch wiki pages I've found that go a long way towards 
reiterating and clarifying things for me.  Again, perhaps more on that 

But the most glaring and mystifying issue, i.e. the (loudest) beep upon 
unplugging and replugging the exernal power supply/battery charger 
remains.  Nothing makes it go away.

My best guess is that because this is a laptop there is no dedicated 
beep speaker and everything does have to go through the sound card; and, 
the final nut I have to turn is figuring out how to identify which ALSA 
channel, if any, is responsible for delivering the offending behavior.  
Despite my best but limited efforts so far it's just not clearly apparent.

Configuring ALSA competently is a bit beyond my pay grade but I expect 
the required information may be found somewhere among these links:
