Comment # 5 on bug 1048934 from Scott Bahling

hmmm. The kernel from home:tiwai:bnc1048934 is not working.

I am seeing the staudio model being activated:

[   22.009551] snd_ice1712 0000:09:00.0: Using board model STAudio ADCIII

But the channels are not being enabled on the expansion box.

BTW, the PCI card used is a Hoontech STA DSP24. The ADCIII is an expansion box
that connects to this PCI card via a proprietary interface most likely
controlled by the GPIO bits.

Here is the content of /proc/asound/card0/ice1712 with the kernel update:
