Hi everybody!

Perhaps someone else have similar side effects? --
I am running MGA7x64 with Xfce4, and in this box there are two
"soundcards" available:

**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: ALC262 Analog [ALC262 Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: Headset [Logitech USB Headset], device 0: USB Audio [USB Audio]
Subdevices: 1/1
Subdevice #0: subdevice #0

Card 0, builtin intel soundchip is automatically set as default in Pavucontrol, hence I can change the main volume via mouse wheel when the
mouse pointer is above the speaker icon in the taskbar.

The second device is a headset which comes along with a volume switch integrated into the usb cable. I saw that there are no shortcuts needed
to set the volume by pressing up or down on the switch.

But: This applies always to the default sound output.

Meaning: When the default output is still card 0 / internal, then the
sound switch of card 1 / usb headset, is controlling sound volume of card
0 / internal out (!)

Creating two shortcuts for AudioRaiseVolume / AudioLowerVolume doesn't
help, since it only tries to overwrite some internal / "hidden" shortcut
and this fails.

Reason behind: I want to be able to easily change the volume of the
headset during phone calls with the headset-builtin switch.

Any trick to get around this? -- Thanks!

Best regards,

Markus

It does make an annoying 'popping" sound though. Probably a hardware thing

It has been a few years since I had your problem and pulseaudio has
made changes so I wish you luck.

I also have the problem of cranking up volume when watching a video
via Firefox and upon FF exit, the next sound played on the system would
be way, way, too loud. Solution was to run alsactl to restore a saved
setting.

Back when I was using ekiga for phone calls, I had to do the same thing.
At the time, I used aumix to set desired device levels and used alsactl
to save the settings.

Currently aumix-text is aumix replacement on mga7 but both fail to run. https://bugs.mageia.org/show_bug.cgi?id=14283

All I can suggest is try using alsactl to save desired settings that
you set via pulseaudio in the mixer setting via that speaker icon
in the task bar.

What you do is set desired normal/default volume level, take a alsactl
save, and pulseaudio save, jack in headset use icon mixer
to set headset level, and alsactl save and pulseaudio save values.

For pulseaudio controls, you need a bunch of pulseaudio information.

Do a quick speed read of man pulse-cli-syntax to get a daunting idea
of the task.

Man pages (man -k pulse-cli) talks about a whole bunch of stuff and
require a bunch of working knowledge to get your head wrapped around
what needs to be done.

Spent a few weeks on that and almost gave up. Found a neat shortcut.
Used some pulsaudio tools to dump current values and did not have to
do near as much work and research of pulse-cli-syntax

Tools of interest are pacmd and pactl.
It becomes a simple matter of running those twice, once for speaker
and once for headset. Diff of the saved files gets you device names
and values. It then becomes a simple matter of programming to create
a script before/after headset use.

to dump current settings
pacmd info > $HOME/pulse_card.info
pacmd dump > $HOME/pulse_card.dump
pactl list | grep 'Active Port:' > $HOME/pulse_card.ports

jack in your head set, use taskbar volume icon->Audio mixer to make any
desired adjustments and get a second dump of headset settings.

I can not be of much more help. I used
https://wiki.archlinux.org/index.php/PulseAudio
to automagically just set default values in the user pulseaudio client
setup files which boiled down to something like


echo "
set-source-volume alsa_output.pci-${_active}.${_type}-stereo.monitor $_volume
set-source-mute alsa_output.pci-${_active}.${_type}-stereo.monitor no
suspend-source alsa_output.pci-${_active}.${_type}-stereo.monitor no
" >> $_fn

That is not going to work for you since you are going to be making
changes dynamically instead of during login.

Before doing a bunch of deep diving of man pages I suggest putting
set pulseaudio from a script
in the first box at
https://www.google.com/advanced_search

to see some examples, then look at your dump diff's for your settings
and values.

I am only running speakers, but when sound problems hit with Linux they
seem to hit hard. and with each release...

Hi all,
and, also from my side: many thanks, Bit Twister!

Yes, a lot to read and a good starting point for configuring the sound architecture.

Well, when logging in as root, setting the volume and leaving the
session, then the volume values are saved as system-wide defaults and are restored on next login as any user. This works.

But, besides this, I need to be able to modify the volume during phone
calls easily and at any time to better react to ambient noises etc. This
is very important when calling to cell phones.
Unfortunately, just set and restore is not enough.

So, usually I use to deploy shortcuts containing commands like these:

amixer -c Headset set Headphone 10%-
amixer -c Headset set Headphone 10%+

But, obviously these shortcuts conflict with "hidden" shortcuts triggered
by the built-in volume switch of the headset.

I have no clue where these shortcuts are defined and how to delete or re- define them. B.t.w., this is not only related to xfce4, as I had to see.

Best regards,

Markus

I hear what you are saying, but do not understand. Using amixer is controlling the system hardware volume. There is nothing in the headset speakers that
can go back and adjust that sound level, to my knowledge.

What I suggest is using pulseaudio cli commands to tell pulse to mute
the speaker channel and enable/control the headset output channel to
get what you are after. Hopefully setting which pulse channel is to be in control would make your keyboard Volume +/- buttons work.

If keyboard does not have Media Controls, then I suggest that you can set/define hot keys to run desired commands or script.

Which reminds me. In the past pulseaudio would attach the channel/device
to my buttons based on the fact that I had the headset jacked into the
front panel at login. If not the external speakers are/were selected.
