3.2: playing music is too CPU demanding

[h01ger]

Qubes OS version:

3.2

Affected component(s):

all

Steps to reproduce the behavior:

play music, eg using mplayer, audio only. look at xentop on dom0. I see roughly 30% cpu usage in dom0 and 20% in the app VM (out of 400% available…)

I think that's way too much.

Expected behavior:

maybe 10% cpu usage on both dom0 and app vm combined?

I used to get around 7-11% when using VLC or Totem (Gnome Videos) on R3.2. Its about the same on R4.0rc5. But when videos were played the usage is more than triple (which is expected).
