FBSD 5.x and Skype sound

[scuba at centroin.com.br]

Hi all,

 	I know that there is a lot o threads about this, but none of the 
workarrounds had worked with me.

 	I trying to use skype (1.2.0.18 from ports), on a FBSD 5.4 (last 
cvs), but the sound is failing.

 	My on-board sound chipset is CMI8738, I'm using the 
snd_cmi_load="YES" in the /boot/loder.conf.
 	I've tried set sysctl vars hw.snd.pcm0.vchans and 
hw.snd.maxautovchans, but nothing worked.

 	The problem is associated only with skype.

 	Any tips?
