For those folks with the "corrupted sound" issue.
Here's how I fixed it.
Convert my fav ringtone to WAV. (Using the wav file you converted above)
Converted my fav reminder sounds to WAV. (Using the wav files you converted above)
Set ringtone thru sounds/notifications.
Used Alarmpal to set sound effects for everything else.
And do NOT use the wavedrv.dll file for the in call recorder.
I had to do this on just about EVERY 6.5 rom so far. Juicy, Copper and now MR5.
I do NOT know the exact sequence of events that causes this, but I know the above fixes it.
Oh, as a bonus, it "rings" faster now too. Still a slight delay, but alot faster than default.
