This is a follow up to the "Status of VIA Envy24 audio controller support in
FreeBSD" from May.
This is a modification of the driver written by Katsurajima Naoto.
Fixes for compilation on recent FreeBSD versions were provided by Konstantin
Dimitrov. For the card specific changes, credits also go to him.
pciconf -lv output:
pcm0@pci0:13:0: class=0x040100 card=0xd6341412 chip=0x17121412 rev=0x02
hdr=0x00
vendor = 'VIA Technologies Inc (Was: IC Ensemble Inc)'
device = 'ICE1712 Envy24 Multichannel Audio Controller'
class = multimedia
subclass = audio
The necessary card specific changes are quite small:

Note that this patch breaks support for other cards -- it's mainly a
proof-of-concept that the driver works. The main difference
between the Dio card is that there is only one AKM452x codec (apart from pin
definitions).
Seems to work quite good so far for me.
I like it much better than the driver from opensound.com (which has troubles
with some applications). At the moment, there are some features missing
compared to the opensound.com driver though.
If someone wants to test this: Be sure to execute mixer pcm 100 first, because
the default value of 75 is very quiet. mixer vol doesn't have any effect.
