ALSA: virtuoso: Xonar DS: fix polarity of front output
commit f0e48b6bd4e407459715240cd241ddb6b89bdf81 upstream.
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.
