---- 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 Touch seeded packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1384952 Title: USB Soundcard no microphone (input) device Status in alsa-driver package in Ubuntu: Confirmed Bug description: My Asus Xonar U7 Echelon External sound device working without input/capture device.
