Linux audio meddling in dom0 - getting alsaequal to work

[daltong defourne]

Hi!

Long story short, I've managed to compile and install alsaequal in dom0 (had to find dependencies, which have different names, and had to edit makefile to point to /usr/lib64 instead of /usr/lib/)

It compiled allright and starts with a lot of different EQ modules.

I am using the following ~/.asoundrc

(borrowed from here http://nairobi-embedded.org/alsa_ladspa_example_usage.html#equalmbeq_1197 )

=====
ctl.equal1 {
type equal
library "/usr/lib/ladspa/mbeq_1197.so"
module "mbeq"
}

pcm.equal1 {
type plug
slave.pcm plugequal1
}

pcm.plugequal1 {
type equal
# slave.pcm "plughw:0,0"
slave.pcm "plug:dmix"
library "/usr/lib/ladspa/mbeq_1197.so"
module "mbeq"
}
=====

alsamixer -D equal1

shows UI as intended and there are no errors.

settings are adjusted and saved okay.

However, the equalizer has *ABSOLUTELY NO EFFECT*
(tested by dropping everything above 500hz and running a sine sweep test video)

I tried using different EQ modules.

I also tried restarting alsa.

No cigar.

Any idea what am I doing wrong and how do I get the EQ to work with qubes sound system?

P.S.:
I know there is a pulseaudio eq. It kind of sucks and on qubes produces a nasty clicking bug that I previously thought to be a "headphones are dying" issue.
