Problems With Realtek HD audion on Pavillion a6230n

Last night i installed Solaris on my hp pailliion a6230n Desktop.

How ever I noticed that The RealTek HD audio chipset wasn't recognized, i have three options are A:) Disable the chip audio card via the bios and install a Creative labs Sound Blaster 24bt PCI card, or Be live with oput sound, or C:) Install the Creative SB Live 24bit pci Card and hope that it is recognizeable to Solaris.

Which potion do you think I should go with.

Do you have to register wit suyn inorder to receive updates?

i would check this site out for some answers: BigAdmin - Solaris OS: Hardware Compatibility List
