********************************
07Mar2018 Dell64 setup to record EU2017 Future Science videos:
11:24 video capture works fine!  but no audio
PulseAudio
- Recording tab : microphone only listed!?

PulseAudio  : 
   1. Configuration tab : 
         EMU20k2 [X-Fi Titanium Series] : Digital stereo (IEC958) Output 
         GF100 High Definition Audio Controller : Off
         Built-in Audio :  Off
   2. Input Devices :  (a,b)  No input devices available
   3. Output Devices : 
         EMU20k2 [X-Fi Titanium Series] : Digital stereo (IEC958) : Digital Output (S/PDIF)
   4. Recording :     (c) 
   5. Playback  :     whole pile of streams (mostly FireFox) 
         System Sounds : (may be grayed out, (a))

change to PulseAudio : 
   1. Configuration tab : 
      x  EMU20k2 [X-Fi Titanium Series] : Digital stereo (IEC958) Output + Analog Stereo Input
         GF100 High Definition Audio Controller : Off
         Built-in Audio :  Off
   2. Input Devices :  
   	x	Monitor of EMU20k2 [X-Fi Titanium Series] : Digital stereo (IEC958)
   		EMU20k2 [X-Fi Titanium Series] Analog Stereo :  Microphone
   3. Output Devices : 
      x   EMU20k2 [X-Fi Titanium Series] Digital stereo (IEC958) : Digital Output (S/PDIF)
   4. Recording :     
   		           EMU20k2 [X-Fi Titanium Series] : Analog  stereo 
   		Monitor of EMU20k2 [X-Fi Titanium Series] : Digital stereo (IEC958)
   5. Playback  :     whole pile of streams (mostly FireFox) 
   	x	FireFox last stream active (>0)
   		Audacious active (>0)
         System Sounds : silent
("x" means set as fallback)

   		Monitor of EMU20k2 [X-Fi Titanium Series] : Digital stereo (IEC958)
   		>> I switched back&forth - I think (IEC958) is desired, but no sound getting through
   5. Playback  :     whole pile of streams (mostly FireFox) 
   	x	FireFox last stream active (>0)
   		>> NO audio activity from FireFox audio stream!!??!! I moved volume control - some little bit
   		Audacious active (>0)
         System Sounds : silent
("x" means set as fallback)


Do I have to shunt audio from [speaker, headphones] to [mic, line in] ???
>> I shunted from Intel [headphone,line-out] (blue audio) to EMU20k2 mic in  (hard to tell which connects are correct!)
