I have checked the volume for voices and its at 100% and not working. Also tried changing the volume to see if it works at other volumes but it didn't work. I've tried compatibility modes for Windows XP, Vista (both service packs), 7 and 8. Tried running in Admin, tried reinstalling, tried re-downloading, unchecked read only and turned off antivirus.
The OS I'm running is Windows 10 Home Edition 64 bit and I'm running my computer with Japanese system locale
