you can either:
1) use my Firmware Utility Script as noted before (website w/full
instructions is now up), which will download flashrom, cbfstool,
gbb_utility as needed, or
2) boot ChromiumOS, one of Arnold the Bat's builds would work fine

coreboot/SeaBIOS do not have any user-accessible settings like a
traditional PC BIOS/UEFI setup.  Furthermore, since you're running the same
(stock?) firmware, any settings related to the onboard sound would be
identical.  I suspect the difference is either hardware or OS related
