It is the first time that I've ever been able to use the external microphone. I find that there seems to be confusion or a lack of clarity in many of the forums with respect to hardware. Although desktops and laptops have become more similar, the prevalence of laptops and portable computers in general have made finding solutions messy, especially for desktops. I was fortunate enough to find this solution in this case. -- Microphone inputs do not work, playback through totem requires restart for each file opened. https://bugs.launchpad.net/bugs/459083 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
