[ALSA] ymfpci: fix swapped channels in SPDIF output
Modules: YMFPCI driver The routing of the effect 2/3 channels to the digital output is the opposite of the rear analog output (left/right swapped). We make the order correct for the digital output (which will make the analog rear have the channels swapped) to make AC3 output work. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
