Hi Ect,

I have a soundcard (Hoontech DSP3000) using the same Envy24/ICE1712 
as the Delta 1010.

I also have experience with hiss problems. I think it
happens when the hardware/software gets initialized into 
an odd state. I recall it's an all-or-nothing thing.

Obviously it is rare enough that Delta et. al aren't having
trouble selling hardware. :-)

I don't remember all the details but do recall a couple
of ways I've used to control how initialization takes place are:

* power cycling the computer (initializes PCI card)
* powering on the external I/O box (usually after the computer is booted)
* loading the snd-ice1712 driver (usually after powering up the I/O box)

You can imagine that a different sequence of powering the
hardware and loading the driver could cause some difference
in behavior.

Hope that helps,

Joel
