Tried flashing a couple different modems (someone mentioned it fixed their problem) but that didn't do anything. Also tried reinstalling Hyperdrive and didnt touch any of the "loud volume" hacks and tried Viper audio with no luck. Cant see to find anyone else really having this issue. Not sure what to do now
I've never had this problem myself and i have never heard of this problem. Try and odin restore to mk2 then do a fresh install of HD15 with a new HD15 download. This is a huge amount of work but it will pretty much fix any general issue that you will encounter. I don't know any specific fixes.
