The firmware theory is a common one. Some laptops have the same problem. But also...
Thank you for reporting this bug to Ubuntu. Ubuntu 10.04 (lucid) reached end-of-life on May 9, 2013. See this document for currently supported Ubuntu releases: https://wiki.ubuntu.com/Releases Please upgrade to the latest version and re-test. ** Changed in: pulseaudio (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/586540 Title: [CA0106/AudigyLS] sound card does not work unless rebooted from windows Status in pulseaudio package in Ubuntu: Incomplete Bug description: Binary package hint: pulseaudio My machine has two sound cards, the first one is the onboard card and the second card (Creative Sound Blaster 5.1 VX) Its detected as "CA0106 Sound Blaster" by pulseaudio. This second card does not work (hissing sound when playing any audio) if I boot directly into ubuntu but works fine if I boot into windows first and then reboot and go to ubuntu. My friend says the card probably uses some firmware which ubuntu is unable to initialize. Hence it works fine when I reboot from windows xp. Let me know if you need any more info. Would really appreciate it if this is fixed, I hate going into windows just to get sound working on ubuntu. Thanks, Relson.
