I found why sounds are muted. In idSampleDecoderLocal::DecodeOGG, new OGG file is opened: // open OGG file if not yet opened if ( lastSample == NULL ) { // make sure there is enough space for another decoder if ( decoderMemoryAllocator.GetFreeBlockMemory() < MIN_OGGVORBIS_MEMORY ) { return 0; } if ( sample->nonCacheData == NULL ) { assert( false ); // this should never happen failed = true; return 0; } file.SetData( (const char *)sample->nonCacheData, sample->objectMemSize ); if ( ov_openFile( &file, &ogg ) < 0 ) { As you see, if decoderMemoryAllocator has not enough free memory, then sound data is not written (results in perfectly zero sounds). The decoderMemoryAllocator is a custom memory allocator with 10 blocks (fixed number) of size 1 MB each. I suppose nbohr1more is right and some sound memory is not freed properly. So the samples stack indefinitely. The fact that they are muted is just a safeguard against unlimited memory growth. |
