The problem began when I noticed my music was strangely only playing the instrumental parts and not the singing. Then I realized that the audio of voices was all garbled so I rolled back my Realtec HD Audio drivers and it still didn't work. Then I ended up uninstalling realtec and reinstalling it. Now my audio is not all garbled but is so quiet that I can only vaguely make it out. In addition Realtec has been replaced by something called 'High Definition Audio Device' and I can't find Realtec anywhere. Any advice welcome. Saw that this info was helpful on another thread so I'll paste it below: Not Available ROOT\SYSTEM\0001 The drivers for this device are not installed.
