Freebsd after RELENGG_5 uses devfs.
And if you load driver after system starts you must build corresponding
device nodes (man devfs man devd)
on kernel loading phase you haven't properly identify your audiocard
codec id:
pcm0: <Unknown AC97 Codec (id = 0x43585431)>
This means, that this card recognized as ac97, but have new, unmanaged
id (0x43585431)
Device id 0x435854 is connexant, lets look, what connexant audio devices
supported in RELENG_6:
ivan:/usr/src/sys/dev/sound/pcm$ grep 4358 ac97.c
{ 0x43585400, "Conexant" },
{ 0x43585421, 0x00, 0, "HSD11246", 0 },
{ 0x43585428, 0x07, 0, "CX20468", 0 },
{ 0x43585430, 0x00, 0, "CX20468-21", 0 },
try add in /usr/src/sys/dev/sound/pcm/ac97.c
in structure
static struct ac97_codecid ac97codecid[] = {
string
{ 0x43585431, 0x00, 0, "CHIPNAME", 0 },
Recompile kernel, restart and look at dmesg.
If device recognozed - try to load corresponding modules.
