Hello Jiri,

Yeah the problem is my bounds checking isn't correct, submitting a patch upstream shortly.

Hi,

I've found my sound defunct in mmotm 2008-09-13-03-09 (opposing to 2008-09-10-19-39).

The problem lays in the newly added function: stac92xx_auto_create_spdif_mux_ctls The count (=5) is out of bounds.
