Well, not what I was expecting at all.
1. "lsmod" after a boot showed various modules, including snd-hda-intel.
2. "lsmod" while music was (not) being played showed additional modules.
3. "lsmod" once the workaround (cable) had been applied and with music 
playing, the modules loaded were identical to case 2.

I have tried two different "content" sources - Firefox and Dragon 
Player.  The behaviour is identical.
