when installing software I'm seeing a lot of errors that look like this, perhaps this is the reason the audio stopped working?
(gconftool-2:2854): GConf-WARNING **: Client failed to connect to the D-BUS daemon: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken. ps shows me: jm 1650 0.0 0.0 32224 2268 ?
