Comment 42 for bug 1201528

* Booted a live Saucy from pendrive:

ubuntu@ubuntu:~$ uname -a
Linux ubuntu 3.10.0-6-generic #17-Ubuntu SMP Fri Jul 26 18:29:23 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

ubuntu@ubuntu:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu Saucy Salamander (development branch)
Release: 13.10
Codename: saucy

* Disabled pulseaudio autospawn and ran with verbose logging as per wiki instructions (log attached).

* Installed mumble and ran it from a terminal, audio playback broke immediatly (the faster I ever seen). Mumble crashed with:
