I have no experience with HDA. In ICE1712/24 the spdif-out outputs 
signal corresponding to the current sampling frequency the chip is 
running on, containing no data. When playing sound, the chip clock 
switches to appropriate frequency, and spdif outputs data of this 
frequency. I.e. if the "parking, idle, default" frequency is 44.1kHz, it 
continuously outputs 44.1kHz SPDIF signal.

I guess if you could force HDA to default to 44.1kHz (no idea whether it 
is feasible), that would be it.
