It's not *so* loud, but yea I appreciate a mixer for it yes! at least
I can tell which speaker is working and also I can listen to Music
without bothering someone else because with LFE the base is loud..

Julien has the same PC, same OS, same Kernel, same BIOS Version, but
the weird thing is that he is not suffering from this problem, which
obviously led me to beleive a hardware defect, but it's working on
Windows!

@Julien, could you plz try the patch (attached
enable-lfe-on-dv7.patch) against
ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/snapshot/alsa-driver-snapshot.tar.gz
? and Tell us if it changes anything for you?
