I’m writing a media player application which uses FMOD for music, and DirectShow for video and DVD playback.
Up to now I called FSOUND_Init and FSOUND_Close only once, during startup and shutdown of the app. This worked fine until I noticed that, even while my audio was paused or stopped (I even turned off the DSP unit), FMOD was still inflicting a significant CPU load. This is a problem when I’m trying to play back videos or DVDs, since the target system is of the 1Ghz mini-itx variety, and needs most of the CPU while playing back full-screen WMV.
I changed my architecture to release all FMOD resources (FSOUND_Shutdown) when going into video mode, with a corresponding re-initialization (FSOUND_Init) when coming back. Here’s where my problems started: for some reason, after calling FSOUND_Close(), I need to call FSOUND_Init() twice, since it always fails the first time (no matter how much time elapsese between the calls). Another problem I noticed is that the FSOUND_Close()/FSOUND_Init() combination seems to leak some memory (roughly 250K or so) each time. I did not do a scientific analysis on this, just glancing at the memory numbers for the app in windows task manager, which creep higher and higher.
Anyway, any help would be appreciated.. thanks!

Omg… how silly of me, that’s what my problem is too (with the memory leak at least). I missed this while re-architecting for the Init()/Close() strategy. Anyway, I’ll fix this and try it out again when I get home, maybe it will take care of the double initialization problem as well.
I didn’t think that there was a memory leak in this library, everything so far had been flawless and tight.
