The following is the results I get after running xfce4-mixer from a terminal. I did install xfce4.4b2 from source back in dapper before i upgraded to edgy.. Everything worked fine then. However, after edgy was installed this along with other applets failed to work. I thought that some of the applets might have gotten replaced by the ubuntu debs for xfce4, so I recompiled xfce4.4b2 and restarted the volume mixer. Now the mixer seems to work partially, but when you open the preferences it takes you to the dialog that lets you pick a mixing device and lets you select which channels you want to be able to control, when i check the boxes I want to control and apply, they still don't appear in the main mixer window. If it is necessary I can take a screenshot of this and attach it. Here is the verbose output for xfce4-mixer:
