If I understand it correctly it is using 0888 PCI subsytem ID. Does that mean 0888 coded ?
Those capabilities lines look a bit strange and in my system lots of interrupts are mapped to same IRQ number.
Also ALSA project changelog do show corrections for buffer size calculations for my codec.
The information that was collected aboe was without running alsaconf. Codec information looks ok to me.
