---- For posterity in case the form post disappears... I found my answer here: https://wiki.archlinux.org/index.php/PulseAudio/Troubleshooting#Microphone_not_detected_by_PulseAudio The summary: I edited /etc/pulse/default.pa to add the line: Code: load-module module-alsa-source device=hw:2,1 ...since "arecord -l" showed that my missing mic was Card 2, Device 1 This newly-added line has to precede the lines: Code: ### Automatically load driver modules depending on the hardware available .ifexists module-udev-detect.so load-module module-udev-detect ...in my case, this wound up being Line 52 of default.pa I hope this can help someone else! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1384952 Title: USB Soundcard no microphone (input) device To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1384952/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
