Unimplemented resampler for mode 0x2 -> 6 channels conversion

[dack@…]

There is no accelerated resampler for 2->6 channel conversion (works without
acceleration at the cost of CPU). I would think that it should just send
everything to the front L/R channels. Log below:

Note - with -ao alsa, the un-accelerated conversion uses a LOT of CPU (enough to
bring an HDTV mpeg ts to a grinding halt on an althon XP 3200+)

whoops - works fine when you compile with optimizations on

:)
