Hi, all. I join alsa-devel today.
I am doing develop Audiotark Prodigy HD2 driver now.
Some problems can't goal to complete.
OS: Linux Ubuntu6.10 (Kernel 2.6.18)
Source: Alsa driver souce included Kernel 2.6.18
/usr/src/linux-2.6.18/sound/pci/ice1712/
Audiotrak prodigy hd2
Envy24HT-S (VT1721)
DAC AK4396 (SN 120dB)
ADC AK5353
output 2ch only, RCAx1, Headphonex1,Optx1
input 2ch, Line-in (but Line goto ADC, Digital IN force to output 2ch)
*input : for AD coverter, Headphone amp
Problems 1 Sounds resolustion is loose
Solution 1
/usr/share/alsa/pcm/dmix.conf
default S16_LE to default S32_LE
@args.FORMAT {
type string
default S32_LE
}
Promblems 2 /proc/asound/cards is displayed "ice1724"

ice->eeprom.version = snd_vt1724_read_i2c(ice, dev, 0x05)
This version, vt1724 is judged vt1712 ! , and result is Invalid.
"No Problem?"
Problem 4 ALSA mix contorol cant mix, or enable?
I dont control gnome volume applet, and fmod's mixing cant control.
Music Player can volume cotrol, but multichannel is disabled. only one !
Question: I want Envy24HT-S control Knowhow.
"Transfer protcols is i2c, Conrotl interface GPIO, and Instruction is
SPI or I2c. "

Please teach me.
