[SOLVED] Webcam microphone works intermittently

I just setup Arch on a new Dell Precision 5520 laptop and, because the built-in camera is positioned under the display, I am using a new Logitech HD Pro Webcam C920. The camera works flawlessly. However, the microphone is only working occasionally. Basically, the sound settings for Gnome, Pulseadio, and ALSA all show the microphone and allow me to select it adjust the its settings, but it doesn't actually pick up any sound. Sometimes, if I physically unplug and replug the device, the microphone will work until the next (re)boot. I've tried plugging the camera into different USB ports on the laptop, docking station, and monitor with no luck. I Googled and search this forum and found others with similar issues, but haven't pinned down a solution yet. Any help would be much appreciated.

Re: [SOLVED] Webcam microphone works intermittently

After spending some time digging into things, I think I may have solved the issue. I noticed that the microphone would occasionally work, and when it did, I dumped some configuration and journal entries and compared them against the same files when not working. While I didn't find any differences that worried me, I did notice that /etc/group had duplicate (and differing) entries, including the gdm group. After removing the duplicate entries and rebooting, my microphone is back to functioning as it did previously, sometimes requiring a replug. But that's better than not working at all. If the things continue to work, I'll mark the thread as solved.
