   Music playback   
      
       CD Analog output 4 pin (stereo) to mobo header (my IDE DVD has this)   
       DVD SPDIF 2 pin interface (stereo), impedance unknown, to mobo header ?   
       (Some optical drives have removed direct audio output entirely)   
      
       Playback via the data cable.   
      
   I would think all of these, still have an opportunity to go through   
   the OS mixer and be adjusted by DSP equalization.

   I have all three sound servers, and no sign of this problem.   
   My kernel is a bit behind your kernel.   
      
   You can edit /etc/default/grub and enable the grub menu to appear   
   at startup, update grub, reboot, select "Advanced" option below   
   the "regular" boot option for that OS, then select a slightly older kernel.   
   This will work as long as the software updater has not trashed   
   all the old kernels.   
      
   With the older kernel in play, then check whether the problem is   
   resolved or not.   
      
   My grub menu is already enabled, as the disk Ubuntu is on is a multiboot   
   (has Mint on it).
