ALSA: virtuoso: Xonar DS: fix polarity of front output
The two DACs for the front output and the surround/center/LFE/back outputs are wired up out of phase, so when channels are duplicated, their sound can cancel out each other and result in a weaker bass response. To fix this, reverse the polarity of the neutron flow to the front output.
