FreeBSD 8.0: how to exchange order of recognized HDA devices?

The problem occured after the installation of an ATI HD4670 graphics 
board, on which one can find an additional HDA device found by the 
kernel before the on-board HDA device is found.
So many clients, like vlc, mplayer etc. do have problems - they either 
play no sound through the usual pathways (via on-board soundcard/chip 
and the attached speakerset and/or headphones).
I see 4 mixer-devices: mixer0 through mixer3. mixer0 seems to be 
attached to the graphics-card, mixer1 shows the usual devices I 
recognize and mixer 2 and 3 are unknown to me, they show up only 2 
facilities.

To make things simple: is there a way to change order of the found HDA 
controller?

Thi8s is what 'dmesg|grep HDA' reveals:

--
hdac0: HDA Codec #0: ATI R6xx HDMI
pcm0: <HDA ATI R6xx HDMI PCM #0 Digital> at cad 0 nid 1 on hdac0
hdac1: HDA Codec #0: Analog Devices AD1988B
pcm1: <HDA Analog Devices AD1988B PCM #0 Analog> at cad 0 nid 1 on hdac1
pcm2: <HDA Analog Devices AD1988B PCM #1 Analog> at cad 0 nid 1 on hdac1
pcm3: <HDA Analog Devices AD1988B PCM #2 Digital> at cad 0 nid 1 on hdac1

Or do i miss something unrevealed?

Thanks in advance,
