Public bug reported: 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.
