The audiodg.exe is still leaking memory from Ventrilo 2.1.4. This has been reported muuuuuuultiple times and it's getting quite frustrating actually.
Also, why am I not entitled to my support at Microsoft's website? Apparently, my "Product ID" has expired. I've had Windows 7 Home Premium for 4 months.
Further explanation of the memory leaking part;
Each time I or someone else talks in my channel, the memory usage increases. This goes on until it hits around 500 mb and my sound stops working completely until I reboot and reset the memory usage. Shutting down Ventrilo once an hour for about 10 min fixes this issue, but this should not be mandatory.
