I can confirm the problem also occurs here, after a fresh install of Ubuntu 9.04 on a Vaio VGN-B1VP, and the fix works.
I applied all available updates per 30 September 2009, played with the levels in alsamixer to no avail (and then restored them to their initial values), then found this mention of an "External Amplifier" setting (through Google). That is to say, disabling this was the only change from the default post-installation settings, and sounds could indeed be played back after the change. I think I just submitted further system details using ubuntu-bug although I don't see them on this page... -- No sound in fresh jaunty install until disabling "external amplifier" https://bugs.launchpad.net/bugs/410933 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
