My sound was running fine until about a week ago. I am currently playing a realm on a realm with friends that is v 1.9.2. At first my sound was just faint but now there is nothing. I have reinstalled drivers, java, and also tried various fixed like reinstalling the downloader and changing the options file to old_options. As this is realms I am playing vanilla with no snapshots. I do use the John Smith legacy and disabled it to make sure it was not causing the conflict. However the sounds were still missing so I re-enabled it. My volume mixer shows minecraft at system volume (not muted) and all my options are set to 100% volume in game. I assume the latest.log will be helpful so I am attaching it.
