I've just installed Ubuntu 8.1 (previously used 8.04). Using both versions, I haven't been able to get my sound to work correctly. Sometimes I've had sound come out of the speakers and my headphones at the same time. Sometimes I've been able to get an external mic to work (never the internal mic). I've got Alsamixer 1.0.17 installed. Can anyone help please? I'm quite new to Linux and would particularly like to be able to use Skype.
