6.0 RC1: sound recording with snd_t4dwave doesn't work

Hello people,

anyone else is having problems when trying to do sound recording (with
gnome-sound-recorder or having a conversation at Skype, for example)
with a SiS 7018 (on-board) soundcard? dmesg tell me this:

pcm0:record:0: record interrupt timeout, channel dead

and Skype stderr shows:

/dev/dsp-1: Device or resource busy

I had that error on FreeBSD 5.4 already, and thought that maybe 6.0
could had solved that.

The machine is running 6.0RC1, with (the default) GENERIC kernel.
Maybe changing the modules?

openglx_at_volahia:~$ cat /dev/sndstat
FreeBSD Audio Driver (newpcm)
Installed devices:
pcm0: <SiS 7018> at io 0xde00 irq 10 kld snd_t4dwave (4p/1r/4v
channels duplex default)

And I do already have this sysctls for sound:

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

Could this be a soundcard problem? I wouldn't be surprised, as the sis
driver for X.org just reboots my machine (problem already solved if I
use the vesa driver).

Thanks in advance,
