Ok, fixed the problem with the disappearing of the soundcard. It has to do with an analog modem that resides in the soundcard. When I installed the driver, then the card disappeared. Uninstalling it fixes the problem.
But still no sound from speakers. Is there something that we can do? I mean how may I test to see where the problem is? -- cannot hear sound in LG P1 Express laptop https://bugs.launchpad.net/bugs/460330 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
