Description:
I found these errors in the Minecraft log file once I had quit, I believe the missing sounds are from DS but I might well be wrong; I based my assumption on the inclusion of the name "Presence footsteps" which I don't have in my mod list but is included with DS I believe.

The two missing sounds are before the other mods' scripts run and the final four thread errors may or may not be related... method "play" might either be sound related or game related so shrug

I hope this is helpful and if they're not your problems then apologies, though I'd be obliged if you have any ideas whom I should be talking to :) Thank you :)

Try the latest DS BETA. Should address the "Error in class" stuff as well as sound engine restart. The missing sounds have been there awhile and are benign. It's on my list of things to chase down and squash.

Pushed v3.4.8.5 with changes.
