I have a similar if not the same problem. It started around the same time. I do not use a kde desktop, only unity but I do run some kde apps e.g. kaffeine. However, I do not know if it is related to use of these. The indicator-sound and system-settings->audio controls are greyed out but I can play sounds. Per session pulse audio will not start for me. If I log out and try another user, their audio is fine. So is lighdm. If I log in again, my audio is still broken. I have tried removing user pulse audio files located in my home directory and /tmp. I have also made sure all processed owned by me are stopped when I logout. However, only a reboot fixes the problem.
If I try to start pulse auto manually using "start-pulseaudio-x11" I get this error at the command line: Connection failure: Connection refused pa_context_connect() failed: Connection refused And this text in /var/log/syslog: Jan 26 12:52:05 hagrid rtkit-daemon[2970]: Successfully made thread 28324 of process 28324 (n/a) owned by '500' high priority at nice level -11.

Why pulseaudio cannot start when I log on with Unity? When I try to start it manually it just drops this message: E: [pulseaudio] main.c: Falló el inicio del demonio. The same message when I logon: Jan 26 00:33:00 64-desktop pulseaudio[25578]: [pulseaudio] module-udev-detect.c: inotify_init1() failed: Demasiados archivos abiertos Jan 26 00:33:00 64-desktop pulseaudio[25578]: [pulseaudio] module.c: Failed to load module "module-udev-detect" (argument: ""): initialization failed.

I actually have sound, but not trough pulseaudio; the speaker icon in the system tray shows disabled and I don't have login sound, I know it is disabled by default, I enabled it, so I expect to hear login sound and have pulseaudio working. I noticed this problem with pulseaudio since an upgrade that the system made automatically on January 18, these packages: Start-Date: 2013-01-18 10:24:02 Install: linux-headers-3.2.0-36:amd64 (3.2.0-36.57, automatic), linux-image-3.2.0-36-generic:amd64 (3.2.0-36.57), linux-headers-3.2.0-36-generic:amd64 (3.2.0-36.57, automatic) Upgrade: linux-generic:amd64 (3.2.0.35.40, 3.2.0.36.43), x11proto-gl-dev:amd64 (1.4.14-2, 1.4.16-1~precise1), linux-headers-generic:amd64 (3.2.0.35.40, 3.2.0.36.43), linux-image-generic:amd64 (3.2.0.35.40, 3.2.0.36.43), linux-libc-dev:amd64 (3.2.0-35.55, 3.2.0-36.57), x11proto-dri2-dev:amd64 (2.6-2, 2.8-1~precise1) End-Date: 2013-01-18 10:30:02 I personally can't find any relation of these packages with pulseaudio, but after I installed the new kernel, pulseaudio sucks when I log on with Unity.
