Title:
[HDA-Intel - HDA Intel MID, playback] volume slider problem - Slide to
bottom and sound stays off even when slider moved up again
Status in “alsa-driver” package in Ubuntu:
Incomplete
Bug description:
The Audio Mixer panel widget slider (current version) has no "mute"
checkbox. The 12.04 version had a mute checkbox in addition to the
slider.
When the slider is moved to the bottom, everything is muted: Master,
Headphone, Speaker, PCM. Move the slider up and only Master is
unmuted.
My computer has three hardware buttons for audio. The mute/unmute
mutes but never unmutes. Same issue.
Known problem: http://askubuntu.com/questions/397819/ubuntu-13-10-and-
xfce4-no-sound-at-all
With 2012.04 I could just uncheck the mute button and things were back
to normal. Now I need to open Audio Mixer and unmute everything.
(It also appears I need to unmute the Headphones to hear sounds from
the internal speakers.)
As someone who works in an environment where I regularly need to mute
this behavior is very annoying.
1) The volume sliders should never mute.
2) There should be a mute checkbox.
3) The unmute options should unmute everything which was muted.
