Memory leak

[hig-dev]

Steps to reproduce:

Hint: You have to enable native profiling and disable Just My Code in the memory profiling settings.

1. Debug the sample app "VisualizationPlayer" with memory profiling
2. Open a music file
3. Force GC and make memory snapshot
4. Repeatedly open the same or another music file. On every new opening of a music file the memory usage will increase. Do this 5-10 times.
5. Force GC and make memory snapshot
6. You will see that the memory usage has increased a lot.

I now found the exact source of the memory leak, after opening a music file, a new ring buffer will be allocated and the old one won't be released from memory:
