I have a Lexicon Omega USB audio interface, which works mostly fine on
my Debian testing system with kernel 2.6.26-2-amd64. The device has
an onboard mixer, and no mixer interface appears to alsamixer. This
is fine, but I can't seem to turn the microphone levels up high
enough. In ardour for instance, if I crank the microphone level
all the way up and yell into the mic, I can just get the signal up to
-3db. That's not enough to record anything quieter though. When
doing this, the peak indicator lights up on the device, so it seems to
be working properly. I've been using linux audio and ardour for
quite a while using other sound interfaces with software controlled
mixers and it has worked fine. Is there something I'm missing on
how to turn the levels up? Thanks!

Four-band parametric equaliser LV2 plugin. DSP code by Fons Adriaensen.

= Overview =
Stereo and mono LV2 plugins, four-band parametric equalisers.
Each section has an active/bypass switch, frequency, bandwidth and
gain controls. There is also a global bypass switch and gain control.
= DSP =
The 2nd order resonant filters are implemented using a Mitra-Regalia
style lattice filter, which has the nice property of being stable
even while parameters are being changed.
All switches and controls are internally smoothed, so they can be
used 'live' whithout any clicks or zipper noises. This should make
this plugin a good candidate for use in systems that allow automation
of plugin control ports, such as Ardour, or for stage use.
= GUI =
The GUI provides knobs and toggle buttons for tweaking filter
parameters. It also provides frequency response widget with
differently coloured curve for each section and separate curve for
total equalization effect.
The GUI uses the External UI extension. lv2rack (part of zynjacku)
supports this extension. Ardour-2.8 needs patch to support the
external UI extension.

Hi all,
Be good to get some feedback on this one - a throwaway pop/punk song -
recorded in Ardour with me doing all the parts (guitar and bass both
through a V-Amp2 - maybe not the best choice for the bass!), drums with
Hydrogen, and vocals through a Samson C01 and a Behringer Minimic 800
into the line of a SBLive. This is a very rough mix - the drums sound
way too weedy, and I think the vocals may be too far forward (and seem a
bit separated from the rest of the track), but I would welcome any thoughts!

oops, I sent us off list, accidentally
anyway, I meant that the userspace networkmanager tool was an issue,
not the wifi kernel modules, ubuntu can use wifi with no xrun issues
if you run dhclient / iwconfig / wpa_supplicant etc. from the command
line.
