I use ICE1724 ALSA driver for Terratec Aureon 7.1 Space card. I have noticed
both default (line out) and plug:spdif devices'es outputs are inverted. Is there
a way to add additional inversion and, as a result, to get "normal" output
signal?
I have a Terratec Aureon USB 5.1 MKII, and have channel inversions too.
Here's the relevant snippet of my asound.conf:
# Terratec Aureon USB 5.1 MKII
# software mixed, multiple access in output only
pcm.dmix51 {
type dmix
ipc_key 12347
slave {
pcm "hw:2,0"
channels 6
}
}
pcm.aureon {
type route
slave.pcm "dmix51"
slave.channels 6
# Front Left
ttable.0.0 0.7
# Front Right
ttable.1.1 0.7
# Rear Left
ttable.2.4 1.0
# Rear Right
ttable.3.5 1.0
# Center
ttable.4.2 1.0
# LFE
ttable.5.3 1.0
}
ctl.aureon {
type hw
card 2
}
The (Rear Left, Center) and the (Rear Right, LFE) pairs had to be swapped.
Also, I attenuated the Front Left and Front Right channels somewhat.
Hoe this helps.

The answer isn't to make the command-and-control system harder to get
around, but to throw the system away. People do their best work not
because they have to, but because they want to, and it's a rare IT
professional who wants to do their best work under the iron fist of
someone who looks to Dilbert's Pointy-Haired Boss for inspiration.
