I imagined it was something like this

idem :)

ah, i didnt know this :) thx!

ahhh.. magic :)  I remembered something like this, but I thought it was solely
due to a sound daemon. I'll look deeper into this to see how to tune it
properly :)

Things I know are happening now:
 - when reloading the hdac.ko (it dies after resume), i need to reset the
sysctl - I need to fix this.

Current settings:
$ sysctl hw.snd
hw.snd.report_soft_formats: 1
hw.snd.targetirqrate: 32
hw.snd.verbose: 1
hw.snd.maxautovchans: 8
hw.snd.unit: 0
hw.snd.pcm0.buffersize: 0
hw.snd.pcm0.vchans: 3


Combos i've tested:
 1- xmms-esound + mplayer : work fine playing simultaneously

 2- xmms-esound + skype : works!! :) 

 3- xmms-esound + linux-firefox (+ linux-flashplugin) - seems to work most of
the time. Restarting linux-firefox makes it work again. Skype definitely seems
to break linux-firefox + flash.(but skype is not affected).

4- xmms-esound  + linux-firefox + mplayer-plugin (tested w/Real Video) : works.
mplayer on top of this also works fine.


Best,
B
