I’ve found what’s happening. Mix_PlayMusic() is silencing all sound channels. Mix_HaltMusic() will unmute the channels so they will play normally.

This didn’t happen in the 2.0.6 pre-release - only music (using MIX_INIT_MODPLUG) stopped working, but sounds still played.

I’ve spent hours trying to build SDL_mixer from source, but I can’t do it. I get make errors. I don’t really know how to use Linux. I got as far as linking the source code into Eclipse, but I got an error something like “Mixer not built with libmod support”. Every forum I have searched has people posting about the same problem but nobody’s posted a solution. Can we have a new SDL_mixer version?

I’ve put together this test code. Pressing 1 will play the sample no problem until pressing 2 to play the mod will silence everything. Pressing 3 to halt the mod will unmute the wav.

Music is also still silent (using MIX_INIT_MODPLUG). No errors are returned, just silence. This worked in 2.0.5.
