Title:
Volume turns up upon connecting USB webcam
Status in alsa-driver package in Ubuntu:
Expired
Bug description:
Hi. I'm using Ubuntu 14.04 (fully updated) on my System76 Gazelle
Professional (version 7) laptop. I recently noticed that after
connecting a USB webcam (Bus 003 Device 008: ID 046d:081b Logitech,
Inc. Webcam C310) while outputting sound via the sound output jack
(VIA VT1802, Green Headphone Out, Front) at the side ramps up the
volume of the output. For example:
1) Connect speakers via the output 3.5mm jack and play some music on either a
distinctly low or high volume.
2) Connect a USB webcam.
3) Sound volume is set to 56 (as per alsamixer).
This happens both when the volume is lower and higher than 56. After
disconnecting the webcam, the volume doesn't return to normal. You can
imagine this is particularly annoying when using headphones!
If you want any other information, please do ask.
