Hi Mélodie,
I've since discovered another problem with my test machine. While I've seen that other testers are able to use GNOME ALSA Mixer, I get the following error every time I open it:
"An error occurred while loading or saving configuration information for GNOME ALSA Mixer. Some of your configuration settings may not work properly."
It has something to do with a bad key or folder named, "/apps/gnome-alsamixer/slider_display_names/SigmaTel_STAC9700,83,84-Master". I've checked and I don't have that folder. Also after a reinstall of GNOME ALSA Mixer, the problem still exists.
Any thoughts or ideas on how to fix this problem? By the way, I just installed alsamixergui and it works fine.
