You want to disable the mixer plugin and use the alsamixer plugin, then 
you'll need to set the config variables required by that plugin.
Here's the info for the plugin from 1.9.2 (I don't have 1.9.0 to hand):

Description:
------------
Mixer for ALSA,. This plugin requires the alsaaudio module from
http://sourceforge.net/projects/pyalsaaudio/. For Debian, install the
python-alsaaudio package and you're all set.

In addition to the plugin specific variables this plugin also uses the
following general configuration variables:

| MIXER_MAJOR_CTRL      = 'VOL' # Freevo takes control over one audio ctrl
|                               # 'VOL', 'PCM' 'OGAIN' etc.
| MIXER_MAJOR_MUTE_CTRL = 'PCM' # used in alsamixer.py, There are systems
|                               # where volume and mute use different 
controls
| MIXER_CONTROL_ALL     = 1     # Should Freevo take complete control of 
audio
| MIXER_VOLUME_STEP     = 5     # Amount to increment the mixer volume
| MIXER_VOLUME_MAX      = 90    # Set what you want maximum volume level 
to be.
| MIXER_VOLUME_DEFAULT  = 40    # Set default volume level.


Plugin configuration variables:
-------------------------------
ALSA_CARDID: Alsa Card id
Default: 0

ALSA_LINE_CARDID: Alsa Line Card id
Default: 0

ALSA_MIXER_NAME: Alsa Mixer Name
Default: 'Master'

ALSA_PCMMIXER_NAME: Alsa PCM Mixer Name
Default: 'PCM'

ALSA_LINEMIXER_NAME: Alsa Line Mixer Name
Default: 'Line'

ALSA_MICMIXER_NAME: Alsa Mic Mixer Name
Default: 'Mic'

ALSA_SYNCMIXER_NAME: Alsa Sync Mixer Name
Default: 'Master Surround'

ALSA_SYNCMIXER: Alsa Sync Mixer Name
Default: '0'

Cheers
