Fixing headphone plugging issues.

[Valkyrie_Lenneth]

This has been fixed for the Benchmark, which is really just a stripped down client. It came with a SoundCoreBridge.dll, that seems to be handling this. No reason to fix it just for the benchmark.

Can confirm its new, not in the previous benchmarks, i checked (still have them all downloaded).

Maybe this means a fix for the expansion is coming.
