Public bug reported: After plugging in an audio device, the volume control appears to stay on the main system device. Therefore, sound is emitted from the external device but when controlling volume, it doesn't change the output level.
It is necessary to go to 'Sound Settings' and change the output device to the one where sound is actually being output from in order to gain volume control of that device. Use case #1: (1) Plug in USB Logitech Clearchat. (2) Control volume from the unity slider Result: Slider moves but does not change output level. Use case #2: (1) Plug in USB Logitech Clearchat. (2) Control volume using keyboard function keys. Result: Volume pop-up appears in Unity showing level changing, but output level does not change. Use case #3: (1) Plug in USB Logitech Clearchat. (2) Use built-in volume control buttons on the audio device. Result: same as case #2 Tested on Intel based desktop running 14.04 Tested on ASUS laptop running 15.04 This is not only limited to Ubuntu, seems present in RHEL6 as well. ** Affects: unity-control-center (Ubuntu) Importance: Undecided Status: New ** Tags: sound volume volume-control -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to unity-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1521381 Title: Volume control does not switch audio device after plugging in Status in unity-control-center package in Ubuntu: New Bug description: After plugging in an audio device, the volume control appears to stay on the main system device.
