This is off-topic, but your other subwoofer remixing bug might be fixed upstream in kernel 3.0.18. From the changelog:
commit cb86f0a0920b63b179d2fa653c6c851db27d069a Author: Clemens Ladisch Date: Sat Jan 14 16:42:24 2012 +0100 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.
