It now indeed does switch on "beats audio" aka subwoofer et al.

However now I got a different problem: When I play a video on youtube,
then
suspend to RAM, and then resume:

* if the music was playing when suspending, then the desktop gets stuck
  after resume:
  no mouse, no keyboard input gets through to the desktop. I can
  Ctrl-Alt-F1 out of X and reboot and that's it. I guess it's the firefox
  flash plugin getting blocked in the kernel while accessing the audio
  device and thus blocking the whole desktop (that's my speculation).

* if the music was *not* playing (i.e. video paused), then after resume
  there is no sound any more. "alsa force-reload" puts the audio in some
  weird state where it gets in a loop playing some short bit of sound:
  tak-tak-tak-tak-tak-tak... So again I reboot.
