I'm having this issue too, if I start or reboot this computer 10 times, 5 times I will get sound, and the other 5 times I won't. This is with the official Lucid Lynx / 10.4 release.
What is even weirder is that when I can't get sound, I can't shutdown or reboot either! If I select those options in GNOME, then I will be thrown out to GDM, and not even there I can shutdown or restart this PC. I have to go to a terminal and issue a shutdown command. Also, sometimes when I restart the computer, I get the preferred resolution and refresh rate, and sometimes I get another random screen configuration (I installed the 195.53 nvidia driver from the ubuntu drivers application). In other problem, I was unable to watch a movie with Totem without missing the sound every 30 seconds, I had to set up the ALSA sink in gstreamer-properties. Pulseaudio seems to be adding more problems than solutions. This is a very recent computer, AMD Athlon X2, 4GB RAM, SATA hard drive, NVIDIA GeForce 8200 chipset. Everything worked fine and happy with Ubuntu 9.04. It's impossible to use a PC that has such random behavior. I have just upgraded from 9.04 to 10.04 and I get only problems, so far this has been the most unstable and headache-inducing Ubuntu release, it is incredible that it is a LTS release. Tell me what can I do, what I need to report, or whatever. I promised to deliver this computer tomorrow to my father with the latest and shiniest Ubuntu (He actually likes the updates every year and asked me to upgrade as soon as he read in the news of this new release), but I think I will need to rollback to 9.04 in such short notice. I'm really frustrated, it's 1am and I have been dealing with this for the whole night. Have sweet dreams. -- module-udev-detect races with module-default-device-restore https://bugs.launchpad.net/bugs/557421 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
