Title:
[USB-Audio - Kensington USB3.0 Video Dock, playback] volume problem
Status in “alsa-driver” package in Ubuntu:
New
Bug description:
1) Ubuntu version:
Using 14.04. Issues were introduced after upgrade from 13.10
$ uname -a
Linux jonas-xps 3.13.0-18-generic #38-Ubuntu SMP Mon Mar 17 21:40:06 UTC 2014
x86_64 x86_64 x86_64 GNU/Linux
2) Alsa version:
alsa-base:
Installed: 1.0.25+dfsg-0ubuntu4
3) What I expected to happen
When disconnecting my Kensington USB dock[1], which has an external sound
card, I expected volumes to either:
- Remain the same as they were before the disconnect [3][4]
- Volumes to be adjusted to 50% or some other saner value than 100%
4) What happened instead
When disconnecting the USB dock, all volumes are set to 100%[5],
including application volumes[2].
Additionally, the external sound card is not selected in gnome-
control-center[5] (see #1250759) and the card volume slider has no
effect.
