>Description:
The snd_cmi driver for C-Media based sound cards does not support the
CMI8787/8788 model chipsets.
>How-To-Repeat:
Boot FreeBSD, or any derivative, with a C-Media cmi8787/8788 based sound card.
>Fix:
I was told this information provided, vai the freebsd-support mailing list,
would assist in possibly a temporary patch possibly for the maintainer of the
driver, however my last attempt at contacting the individual in development of
the snd_cmi driver's email returned to me stating the e-mail was invalid.
This was from the log generated:
none3@pci0:5:4:0: class=0x040100 card=0x82751043 chip=0x878813f6 rev=0x00
hdr=0x00
vendor = 'C-Media Electronics Inc'
device = 'CMI8788 [Oxygen HD Audio]'
class = multimedia
subclass = audio
The sound card in question is a CMI8788 derived ASUS Xonar DX PCIe.
I have attempted to remedy this using the ports collection's 4Front OSS driver,
but all attempts to successfully load the driver result in a system that locks
up, freezes, or refuses to boot.
