I got a clue somewhere to look in
Settings / Settings Editor (not the normal Settings Manager)
Then, under xfce4-mixer
, there was the setting /active-card
which had the value:
PlaybackHighDefinitionAudioControllerDigitalStereoHDMIPulseAudioMixer
I selected 'active-card', and hit the 'Reset Property' button. That turned the setting into:
PlaybackBuiltinAudioAnalogStereoPulseAudioMixer
( These names closely follow the names of the Output Devices in pavucontrol
see screenshot )
After a reboot, it worked. My volume buttons now affect the volume in the speakers.
(Scrub my earlier, now deleted, hint/comment about Play/Pause not working. They (still) work fine in Rhythmbox - that was/is an unrelated problem with gmusicbrowser
)
This may or may not work for you! :-)
EDIT: For some reason, my xfce profile got corrupted and I've restarted from scratch by rm -rf ~/.config
. Now, only a few days later, resetting it didn't work for me either, but setting /active-card
to PlaybackBuiltinAudioAnalogStereoPulseAudioMixer
did.
EDIT: If the above did not work try setting this via terminal and xfconf, e.g.
xfconf-query -c xfce4-mixer -p /active-card -s 'PlaybackBuiltinAudioAnalogStereoPulseAudioMixer'
It looks like you're not using the default Xfce volume slider (perhaps in Xubuntu it is default, but not in Xfce). I suspect that you're using the indicator plugin, which I don't like nor use. I would suggest that you try adding Audio Mixer
plugin to the panel.
To have it available you need to:
sudo apt-get install xfce4-mixer

The release notes for Xubuntu 13.10 include this problem as one of the known issues for that release. (See link to release notes below.)
https://wiki.ubuntu.com/SaucySalamander/ReleaseNotes/Xubuntu
This problem has been fixed in the current development release and a stable release update is currently pending to fix this issue in 13.10
Any prior work-arounds were deemed dangerous to system stability in the Xubuntu team meeting on 2013-12-05. Users were strongly advised from that point forward to not implement them in any manner.
This has now been released to
saucy-updates
and once a system is updated after install no longer an issue.
