Multiple Sound Sources Problem

[Soheil Hassas Yeganeh]

Hi,

As http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/sound-setup.html
said for "Utilizing Multiple Sound Sources", I have run two sysctl
command below:

# sysctl hw.snd.pcm0.vchans=4
# sysctl hw.snd.maxautovchans=4

It creates 4 virtual channels for me and multiple sources can play
simultanously.

But when I play music, the sound plays slower than when I have no
vchannel. I test this with totem and xmms and both have the same
error!

How can i solve this?

Thanx,
Soheil,
