As mentioned, the forum does not function as a queue for answers. The technical support staff (not developers) read many threads, but they cannot read them all. Instead, this is a place for players to work through issues that are within their control – supported by volunteers, community, and sometimes the staff.
Lots of players have tried to help you, but you haven’t responded to some of the suggestions in your previous thread. I realize this is frustrating, but this is not a hot topic in the forum. That tells us that the issue is likely something to do with the sound processing on the monitor or your personal setup of the computer.
Since duplicate threads are not allowed in this forum, please either continue working in the previous thread, file a ticket as suggested above by Zungar, or do both. While configuring your sound settings isn’t something Blizzard directly supports (like crashing and disconnecting), maybe they have other ideas to suggest.
