I've also tested model=hp-dv5 and I think - I'm not sure - it doesn't use
the subwoofer same as with Nicolas.

What's sure however is that it's showing the same symptoms as
model=hp-dv7-4000 after wakeup as described here:


Nicolas, are you able to suspend your machine while playing (or not)
sound? Does your sound-system come up in order again after wakeup?
