I don't find what I have changed to have the bug reappear. I have no sound when GDM start before I open my session, so I don't think this is a problem related to my personal settings.
I have tried to remove pulseaudio, the problem is still here. This is the last actions I did when the problem appeared : sudo gedit /etc/security/limits.conf sudo adduser theo audio sudo adduser theo disk And this is the history of my synaptic from this same period : 04/05/2009 following packages updated : acpid (1.0.6-9ubuntu4.9.04.2) to 1.0.6-9ubuntu4.9.04.3 bluetooth (4.32-0ubuntu4) to 4.32-0ubuntu4.1 bluez (4.32-0ubuntu4) to 4.32-0ubuntu4.1 bluez-alsa (4.32-0ubuntu4) to 4.32-0ubuntu4.1 bluez-cups (4.32-0ubuntu4) to 4.32-0ubuntu4.1 bluez-gstreamer (4.32-0ubuntu4) to 4.32-0ubuntu4.1 bluez-utils (4.32-0ubuntu4) to 4.32-0ubuntu4.1 checkbox (0.7.1) to 0.7.2 checkbox-gtk (0.7.1) to 0.7.2 consolekit (0.3.0-2ubuntu3) to 0.3.0-2ubuntu4 cups (1.3.9-17ubuntu2) to 1.3.9-17ubuntu3 cups-bsd (1.3.9-17ubuntu2) to 1.3.9-17ubuntu3 cups-client (1.3.9-17ubuntu2) to 1.3.9-17ubuntu3 cups-common (1.3.9-17ubuntu2) to 1.3.9-17ubuntu3 evolution-exchange (2.26.0-0ubuntu2) to 2.26.0-0ubuntu3 libbluetooth3 (4.32-0ubuntu4) to 4.32-0ubuntu4.1 libck-connector0 (0.3.0-2ubuntu3) to 0.3.0-2ubuntu4 libcups2 (1.3.9-17ubuntu2) to 1.3.9-17ubuntu3 libcupsimage2 (1.3.9-17ubuntu2) to 1.3.9-17ubuntu3 libpam-ck-connector (0.3.0-2ubuntu3) to 0.3.0-2ubuntu4 libudev0 (141-1) to 141-1.1 libvolume-id1 (141-1) to 141-1.1 libwmf0.2-7 (0.2.8.4-6ubuntu1) to 0.2.8.4-6ubuntu1.1 libwmf0.2-7-gtk (0.2.8.4-6ubuntu1) to 0.2.8.4-6ubuntu1.1 ubuntu-docs (9.04.9) to 9.04.10 udev (141-1) to 141-1.1 update-manager (1:0.111.8) to 1:0.111.9 update-manager-core (1:0.111.8) to 1:0.111.9 following packages installed : ardour (1:2.7.1-2ubuntu1) libaubio2 (0.3.2-2ubuntu3) libgnomecanvasmm-2.6-1c2a (2.23.1-1) liblo0ldbl (0.23-2.2) libvamp-hostsdk2 (1.3-1) libvamp-sdk1 (1.3-1) python-crypto (2.0.1+dfsg1-2.3ubuntu5) python-twisted (8.2.0-2) python-twisted-conch (1:8.2.0-2) python-twisted-lore (8.2.0-0ubuntu1) python-twisted-mail (8.2.0-2) python-twisted-names (8.2.0-0ubuntu1) python-twisted-news (8.2.0-2) python-twisted-runner (8.2.0-0ubuntu1) python-twisted-words (8.2.0-2) gstreamer0.10-gnonlin (0.10.10-2) jokosher (0.11.1-0ubuntu1) python-setuptools (0.6c9-0ubuntu4) 05/05/2009 following packages installed : boinc-client (6.2.18-3ubuntu1) boinc-manager (6.2.18-3ubuntu1) Do you have an idea where I cant investigate this problem ? -- snd-ice1712: no sound if SPDIF is unplugged https://bugs.launchpad.net/bugs/355263 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
