I get bass redirection without asking and without a .asoundrc.  That is, when
I play a 2-channel file with, e.g., aplay, I hear plenty of bass coming from
my woofer.  I wonder what the relevent differences are between our systems.
I have Audigy2 zs, use Linux 2.6.6 with driver emu10k1 compiled July 21 from
Alsa CVS.  Using alsamixer, I unmuted "Tone" and set "Bass" to 50; "PCL LFE"
and "LFE" are at 68,  I use the 3 analog stereo jacks to connect to a cheap
5.1 powered speaker system, with woofer volume control at about 25%.
