my Ubuntu 12.04 shows no audio input device, the list of audio input devices is empty. I've tried several solutions suggested to this issue (editing alsa-base.conf, installing paman, pavucontrol, etc.), but none seems to work. Also noticed this bug report from over a year ago: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/990993 Does anybody know of a workaround? I'd like to be able to record sound with Ubuntu. Thanks in advance.
