Running FOv0.4.4 (built from SVN) on Ubuntu 14.4 with a Lenovo G505s (ie., AMD A10).
Clicking on a drop-down menu from the "Galaxy Setup" (GS) window, after selecting "Single Player" from the main menu, then clicking on the top of the menu again, causes a sound glitch. The cound is repeated multiple times. An example: click on the "Sprial, 3-arm" text and a menu appears; click again in the same place and a sound glitch occurs. This happens for all the drop-down menus.
