0.4.10-RC-30-g51a70dc gcc dbg lin, VBox 4.3.12 with installed AC97driver from rapps
Pocket Tanks 1.6 from rapps.
The game never does play any music or sound. Although the sound driver is properly installed and gives sound in other apps. Sysaudio is also currently not "sucking" (CORE-9475).
For some unknown reason the game does not give any sound at all in ros, but does in XPSP3.
This is nothing new, I tested this game since every release since 0.4.0 and I never had sound.
