Well, I could work on the driver, it would be similar to Juli. ice1724.c is mostly ready for the proprietary clock model. The aforementioned chips have complete documentation publicly available. If I had the card physically to trace connection and test (I am no Takashi the wizard :) ) and some documentation available, it should be viable. Honestly I am not going to purchase it myself, I have no other use for it plus PCI is almost history now. Unfortunately I have not met any PCI-express card with quality 44.1kHz playback (i.e. dedicated crystal clock).
