I ran a diff between the 1.0.14 alsa-driver folder from via-linux-audiopackV1.5.tar.gz and from a 1.0.14 which i download from alsa-project.org. Only thing that was altered was the patch_via.c file (attached). Most interesting is the line:
"pin = 0x20; //to fix bug on nc1502"
But there are lots of other alterations in there too. It appears to be derived from a later version of alsa-driver.
I overwrote the patch_via.c file from 1.0.16 with this one and compiled and installed the driver. Still no headphone joy.
