Comment 11 for bug 1440675

The purpose and value of opening alsamixer could be explained both as a tooltip for this button and in the manual. The manual could go into more detail, such as explaining how it is different from pavucontrol.

The UI should be as self-explanatory as possible so users have to refer to the manual as little as possible. Most people do not read manuals for anything and many those who do, such as myself, would prefer to not have to refer to the manual. Although it would be inappropriate to bend over backwards for users who would never bother to read the manual, I think simple changes to the GUI such as this button could make the manual less necessary to read. IMO, only things that are too complicated to explain with a well designed GUI should go in the manual.
