PCIe audio cards: what is tob be preferred with FreeBSD 8.0/9-CURRENT?

[O. Hartmann]

Well,
At this very moment I utilise a M-Audio 5.1 PCI-audio board with which 
I'm really satisfied. My next box doesn't have PCI slots at all (ASUS 
P6T6-WS Revolution) and due to the fact I'm using Windows 7 sometimes 
for recreational gaming, I'd like to have a moderate expensive audio 
board with the workstation which is supported by FreeBSD 8/9. In the 
past - means two or three ywars ago, I had problems with Soundblaster 
PCIe boards, so I was recommended avoiding those and choosing the more 
elabotrated M-Audio cards for the PCI bus.
At this moment, I look for the Soundblaster X-Fi range of PCIe cards, 
but I'm not sure whether they are supported by FreeBSd 8/9. Any suggestions?

Regards,
Oliver
