Sound patches and volume problems?

I installed the massive sound patches from
on a laptop running an up-to-date 5.4-stable:
tingo at kg-jobbpc3$ uname -a
FreeBSD kg-jobbpc3.kg4.no 5.4-STABLE FreeBSD 5.4-STABLE #3: Thu Aug 25

The patches lets FreeBSD detect all the usb audio devices that I have;
this is good.
However, there seems to be some problems with the volume controls... it
seems like the volume is ... sort of relative now, not absolute.
And when I adjust volume, equalizer settings etc, it seems lie the
volume gets ... well, lost, and gets louder all the time, until finally
I have to shut down xmms to save my speakers / headphones.
The last device tested was a set of USB speakers from Jazz Speakers
(model no. J1116U), and theyu have the same problem.
Here are the lines from /var/loig/messages showing how the speakers are

Currently, I have only tested with xmms, because there is no easy way in zinf to chenge output device.
I'm sorry that my little "problem report" isn't more accurate, but so far I'm just seeing the symptoms, and don't know where to start looking for the problems yet.
