I am experiencing the same issue. I hopped onto the upstream irc channel and here are some snippets of the conversation:
<achiang> hello, mumble 1.2.3-2ubuntu2 is hanging for me on startup, i get stuck in the audio wizard. a quick strace shows that it's infinitely doing a sched_yield() call <achiang> any further debugging i can do? <pcgod> achiang: your audio device is probably in use <pcgod> (which will cause it to hang when it tries to play the audio file in the audio wizard) I used lsof to try and find any open files related to sound to kill them off. That didn't seem to work. After killing mumble and restarting, I tried to just skip the audio wizard completely and just connect to a server, which also hangs: <achiang> and now mumble is hanging upon trying to connect to a server <pcgod> achiang: which is the same problem... the default settings have an "on connect" sound and it enters the same infinite loop when it tries to play that -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/844347 Title: mumble in oneiric hangs when connecting, or using audio wizard...
