I believe I caught it while paplay was still working.  The new pacmd ls 
output is at <http://gene.homelinux.net:85/gene/pacmd-sl.out>

Now one of the channels is said to be running.

Exactly as it worked flawlessly under F10 with pulse disabled, all analog via 
the mini-phone plugs on the card, nothing has been disturbed, and I do hear 
the thump in the woofer when udev starts.

FWIW, pavucontrol looking at analog output, with or without amplifier, shows 
the music playing in its vu bar.

I'd say we were close, close enough for me to crawl under that desk and turn 
the machine around, unplug the audio cables and see if a finger makes any 
noise.  OTOH, I do hear the thump when udev starts at reboot time, so I 
believe the audio signals cabling chain is ok.

Aha!  I found it!  I configured kmix to show me every channel, which makes it 
about 2x my 1680 screen width, and pulled its window to about 1/2 screen 
height so I could read all the labels, and found the last control on the 
right was muted.  It is called "Audigy Analog/Digital Output Jack"
I knew that turning on the IEC-958 muted it, and that is muted as it should 

Frankly, I am inclined to say its a bug, when selecting the analog stereo 
output in pavucontrol, that it should be automatically un-muted.

And it doesn't have near the gain it did have.  Listening to cnn, I have 
everything wide open and its just a comfortable level. (to these 75 year old 
ears that is)  It certainly would not wake anybody outside this room.  There 
is also a background hum that comes and goes, somewhat like the 59.94hz vs 60 
hz beat from the old NTSC broadcast facility, like something is wide open.  
That was the microphone circuit, which has nothing plugged in but a cable 
about 6" long that jumps the pcHDTV-3000 tv cards output back into the 
Audigy2.  And I just got the pling from kmail's new mail pinger.

It also sounds as if there is a lot of bass boost that wasn't there before, 
and despite its running at what pavucontrol says is just an average level, I 
am hearing some digital flat topping.  I'll probably be able to find that 

So, we have a case closed I believe, and a bug that ought to be fixed.

Thank you for your patience Colin.


Cheers, Gene
