Xfce4-mixer blank.

Howdy,
I seem to be having some trouble with xfce4-mixer. When I open it, it shows as completely blank. No controls show up at all. Alsamixer shows options, and allows me to alter them. But I am unable to get xfce4-mixer to recognize controls at all.
I can confirm I am in the audio group also.
Alsamixer
xfce4-mixer default Selected
xfce4-mixer intel selected
xfce4-mixer blank
When I run xfce4-mixer from command line, from either root or my user, I get the following:
$ xfce4-mixer

I'm knocking this old thread to report I had that very same problem... xfce4-mixer does not seem able to detect the soundcard and write an initial configuration file by itself.
The solution I found was very ugly, but it worked: I installed gnome-alsamixer, made all necessary settings and then closed it. Now xfce4-mixer can detect the soundcard fine- quite obviously using the gnome-alsamixer config.
PS: On one instance of it I can also get the mixer settings by logging X as root (NOT running "sudo xfce4-mixer" - for some reason it doesn't work), setting everything up and running "alsactl store" and the logging back as normal user. Obviously it's a permissions issue, but I'm not knowledgeable enough to find out what's happening.

[split] xfce4-mixer window is blank

Heh...I never knew about that either! Although...mine just loads up a blank window. When I try to switch under File -> Options -> Device from default to NVidia nForce2, the setting doesn't stick and I get no options for adjustment. Any suggestions?

Well, after taking the suggestion from the old thread, the mixer will load properly when I use the panel launcher. I did have to right click on it and select the correct device, but then it would launch correctly.
Unfortunately, trying it from the command-line still doesn't work, and I don't want to have it on my panel all the time. As it was mentioned by the other person with the same problem, if I load up the blank version by issuing <code>xfce4-mixer</code> from the CLI, go to options and try to change the device, there's no effect.
There isn't a <code>man</code> page for <code>xfce4-mixer</code>, so I'm not sure if there's some CLI switch I can pass to it for it to work. Any suggestions?

[SOLVED] xfce4-mixer unexpectedly stoped working

Hi archers,
i am having this problem a couple of days now and i couldnt find something usefull in wiki
xfce4-mixer panel pluginn stopped working with the following message
Plugin "Mixer" unexpectedly left the panel, do you want to restart it?
User is member of audio group in case it matters...
I have no clue if this is a matter of groups, permissions or package
I am using now xfce4-mixer 4.8.0-3 after downgrading from xfce4-mixer 4.8.0-4 but the problem remains the same
thanks a lot

Try to right-click on the mixer and choose Properties. Then select your Sound Card and the Mixer Track and choose close. Hopefully the mixer applet will now work.
That is what I have to do on some kernel updates usually. With the drivers being built into the kernel sometimes the settings get wonky when you update that. Reselecting the items in the Mixer Properties generally fixes the issue.

Quod libet keyboard shortcuts/xfce4-mixer

Can someone suggest some keyboard shortcuts, like to increase/decrease volume, forward/rewind, etc.
Also, when I start arch, in xfce4-mixer, headphone and pcm levels are zero by default and I need to increase them on every boot. Is there a way to change their default values.

Add alsa to the DAEMONS array of rc.conf

Mapping media keys to xfce4-mixer

I tried to search and find someway to link my media keys on XPS M1330 to my xfce4-mixer. My keyboard is setup as evdev, running xev shows my keys are already set to XF86Audio(something). I even tried to map xmodmap and it didn't help. Anyone know if it is possible to map keys to control xfce4-mixer?

Maybe, I don't know. I have solved it using another software that comes with ALSA. (The result is the same, it will show up in xfce4-mixer too)
Menu -> Settings -> Keybord --> Application Shortcut Tab
Button Add
Command: amixer -c 0 sset Master 5+
Command shortcut: *Press your Vol+ key*
Button Add
Command: amixer -c 0 sset Master 5-
Command shortcut: *Press your Vol- key*
Button Add
Command: amixer -c 0 sset Master toggle
Command shortcut: *Press your Mute key*

PulseAudio and xfce4-mixer

Is any other mixer who works like xfce4-mixer and have pulseaudio support?
I need mixer in tray which works with Pulseaudio.
Cheers

I did not mean to bump old posts, but wanted to give a solution for other who may search.
In AUR repository there is a nice program called obmixer, which I now am happily using with FVWM... It is good, as it can work with alsa and pulseaudio... I love it as it stays in a tray...
Alternatives may be gvolwheel or gvtray, but both only works with alsa...

Xfce4 mixer question

does anyone know how to change the mixer on the panel to use the master volume instead of master1? (or alternatively, i guess, change applications to be volume controlled by master1 instead of master? )
before the latest upgrade i could control overall volume and things like web browser plugin volume, etc. with the indicator on the panel, now i have to actually open the mixer (which kind of defeats the purpose of having the level meter on the panel ). i checked the various ~/.xfce4 config files, but i didn't see anything that assigned that in any of them. i changed the libmixer.so value in xfce4rc to id="0" and id="1" (default seems to be id="-1") but that didn't work. (i'd like to change the icon too, if anyone knows how.)
otherwise xfce4 4.2.0 rocks! icons on the context menu are awesome, and a lot of the interface is much better. kudos to the xfce4 team!

mixer on the panel = volume control ?
What is master1 ? I only have Master;0
You can choose "wannabe master" in the properties of volume control item.
You can also mark "useful controls" in sound section of xfce settings manager.
I guess I don't really understand what's your problem with mixer settings (I'm assuming you have xfce4-mixer 4.2.0-1). You can't see
all mixer controls in xfce sound settings and/or mixer (volume control) properties ?

BTW it's now ~/.config/xfce4

You can also try new xfce4-terminal:
http://bbs.archlinux.org/viewtopic.php?t=9306
The only problem I'm having with 4.2 is that it now starts on all screens and displays (I have :0.0 (crt) and :0.1 (tv)) and I don't know how to start it only on crt (I don't need it on the tv). The previous version didn't do it. I already modified all settings and I'm using my own .xinitrc (startx). When I remove session manager it still starts xfdesktop on the tv. Anyone knows a solution????

Xfce4 mixer problem

Ah shoot. I get that same "message" over and over again too, but it's not related to your problem. I think that's just a GTK widget problem with the panel, trying to resize and fit some stuff I guess. That constant "message" is, however, interfering with seeing what's crashing, since it's scrolling off that VC. I don't know where else xfce4 pipes it's errors to.
I'll check through the source a bit and see if I can help you out.
You could try this for capturing the VC/1 output: "startxfce4 &> /tmp/xfce4.log"
Start up xfce that way, open up a terminal in xfce and use "tail -f /tmp/xfce4.log" (hit ctrl-c to cancel the "tail" process at any time). Try to repeat those steps which give you an error with the settings menu, and watch what reads out in your terminal. If for some reason it crashes, open up that file later and look at the last few lines in the file before it crashed. You'll probably have to scroll down a bit since it will probably pipe all your xinit stuff in there too.

Xfce4-mixer crash on mouse scroll volume change attempt

Hi,
I have the latest (4.8.0-1) xfce4-mixer plugin installed and it crashes 100% of the time when I try to change the volume by moving the mouse over it and start scrolling. Everything else works as expected.
Any ideas how to make it work?
Thanks.

Hey,
I seem to have the same problem. In /var/log/everything.log I see:
"xfce4-mixer-plu[2354]: segfault at 24 ip 0000000000406553 sp 00007fff8c864640 error 4 in xfce4-mixer-plugin[400000+a000]"
It could be a bug that is only present when debug output is disabled. See: https://bugs.archlinux.org/task/24323
The bug was filed in May 2011, so it could be a different problem. I didn't have time to test it yet cause I'm having exams at the moment, but compiling it with " --enable-debug=minimum" might help.
Good luck

Xfce4-mixer failed to start

Hello,
I have installed Arch Linux and XFCE for two weeks now and I'm very excited with this flexible distro. The only issue that i have is the functionality of the xfce4-mixer. I click on the applications-multimedia-audio mixer and while the process be displayed on the task manager, the GUI window won't open. After a reboot the problem may be solved but after another reboot the problem returns.
When I run as a root the command: xfce4-mixer, the output which displayed is:
xfce4-mixer: Failed to initialize xfconf: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.
I have nvidia sound card and (on board) hda intel but following the wiki: https://wiki.archlinux.org/index.php/Xfce#Xfce4_mixer
I changed the default sound card from settings-editor --> xfce4-mixer replacing the value of sound-card to the PlaybackBuiltinAudioAnalogStereoPulseAudioMixer
to fucntion correctly with PulseAudio. I executed several reboots and the xfce4-mixer opened correclty. Unfortunately today, the problem returns again.
When I'm trying to kill the process of the xfce4-mixer, I can't.
I tried set the default sound card following the wiki: https://wiki.archlinux.org/index.php/Ad … sound_card but nothing changed.
The sound and the alsamixer works fine.
How can I fix it ?
Thank you in advance !

Make sure that xfconfd is running.
As a note, xfce4-mixer is no longer being actively developed. From the release notes:
Due to gstreamer1.0 having dropped the mixer-interface entirely, and xfce4-mixer and xfce4-volumed relying on this interface with gstreamer0.10, our mixer application and volume daemon cannot be ported to 1.0 and are consequently not maintained anymore.
A new pulseaudio mixer plugin has been added to the Xfce git tree - you might want to give that a try. From the readme file:
Xfce4-pulseaudio-plugin is a panel plugin for controlling an audio
output volume of the PulseAudio mixer. The volume can be adjusted using
keyboard shortcuts, mouse wheel, a slider in a popup menu (todo), or via
a linked external audio mixer tool.
It works in a manner very similar to xfce4-mixer but more integrated with pulseaudio.

Xfce4-mixer doesn't unmute alsa after setting volume to 0% and back up

Hey guys,
I'm no newbie to Arch, so maybe I just need some cold water in my face because I'm overlooking something obvious.. Yesterday I did a complete re-install from an arch bootstrap script and got everything running just the way I want again - except for one thing.
I am running Xfce as my DE with the xfce4-mixer applet in the tray to control the Master channel's volume using the mouse scroll wheel. This always used to work fine for me. Alsa is up and running and I get sound. The only thing is that when I completely turn down the volume by scrolling down over the speaker icon in the tray (because my phone rings for instance) and then scroll it back up again, alsa somehow seems stuck in mute mode. I have to open a terminal window and use alsamixer each time to unmute the volume again .
This seems like strange behavior on the part of xfce-mixer to me, and it is not something I have encountered before. Anyone have some tips or tricks to fix this weirdness?
Thanks,
welpert

lucke wrote:Maybe you can mute and unmute with middle click? It works in some mixers.
Alas, no luck.. But scrolling up from 'muted' should have the same effect as middle-clicking, at least I assume both actions activate the same unmute function somewhere in the code..
EDIT: For now I'm going to use volwheel. But.. please don't hesitate if you know the answer bacause I like xfce4-mixer's simplicity.

New install - starting xfce4 returns blank sreen.

Hi All,
I have just attempted my first Arch install, on a Toshiba Tecra A10 laptop.
The install went through fine, after configuring the network I have updated the system successfully but I'm having a problem getting my DE running.
I installed xfce via the following commands (as root)
pacman -S xorg
pacman -S xfce4
pacman -S xfce4-goodies
When I try to start xfce4 via "startxfce4" the screen goes blank (entire screen is black with two white underscore type things at the top of the page)
I have tried to start xfce4 as a non root user (user created via "useradd -m -g users -G audio,lp,optical,storage,video,wheel,games,power,scanner -s /bin/bash hardeep" but that also returns the same blank screen.
Using this same workflow I was able to get xfce4 running in Virtual Box so I assume the problem is with the video card drivers.
I did try to install a video driver via:
pacman -S xf86-video-nv (i'm pretty sure the Toshiba A10 has a Nvidia card)
That didnt help, I also gave the generic vesa driver a go but again same problem.
Any ideas on this would be much appreciated.
thanks
Hardeep

Just out of curiosity, because I don't know XFCE well and so it probably won't work: did you try just starting it through "startx" instead of startxfce? Also, boot it with the nomodeset grub option and, if it still refuses to work, post the output of xorg.conf (if you have one, otherwise pastebin the Xorg.0.log)
EDIT: please tell me you put the nv module to load in the MODULES section of rc.conf?
EDIT2: Is THIS your computer? Because it has an intel graphics chip. If it is, problem solved...

Alsa-mixer can't start

Hi!
I don't know where to start this topic really but after a reboot volti couldn't start in the start in the fluxbox-systray and i couldn't get any audio. When i tried to start alsamixer with alsa-mixer, amixer commands alsamixer couldn't start and neither gnome nor xfce4-mixer could start and when i tried running the CLI ALSA frontend the terminal prompts: "cannot open mixer: No such file or directory" amixer prompts: "amixer: Mixer attach default error: No such file or directory".
Now i tried using different frontends and multiple google-searches didn't find me a solution, from a live cd i could access ALSA, i tried "ls /dev/snd/control*" which also couldn't find file or directory. My user is added to audio-group in /etc/group. Alsaconf can't find any soundcard or drivers. There is no /etc/modprobe.d/sound.conf either?
Now the really curious thing is pacman, which works flawlessly apart from this can't uninstall or install alsa, alsamixer. alsautils. Only the gtk frontends. but i can find the applications using the locate command.
I think this could be a udev issue. I updated it recently and I fooled around a little with udev to enable auto mount of usb and such as described in the arch-wiki. But I don't where to start searching or how to check where the problem lies.
I would be really thankful for any advice on where to look or help concerning this problem.
//Jonathan

mutanabbi wrote:I tried updatedb as sudo now and get no error. I guess this might enable me to reinstall alsa, so I'll try that
OK, but that doesn't help with the kernel. Rebuild initramfs
mkinitcpio -p kernel26
and reboot.

XFCE's mixer plugin stops at 90% when using scroll wheel over icon

Yeah, title says it. By putting the cursor over the icon and using the scroll wheel, the volume goes up to 90%. But when I open the mixer and drag the master slider, it goes to 100%. How do I fix this?

Had the same Problem, was really annoying me. Probably a baaad baad bad workaround:
in src/xfce4-mixer-4.6.0/panel-plugin (ABS / xfce4-mixer)
changed xfce-volume-button.c, line 204 & 205:
/* Create adjustment for the button (from 0.0 to 1.0 in 5% steps) */
button->adjustment = gtk_adjustment_new (0.0, 0.0, 1.0, 0.05, 0.05, 0.1);
to
/* Create adjustment for the button (from 0.0 to 1.0 in 5% steps) */
button->adjustment = gtk_adjustment_new (0.0, 0.0, 1.1, 0.05, 0.05, 0.1);
rebuild, done.
I've been searching for a while for the real problem, but I'm no programmer. Looks as if somewhere someone perhaps startet counting at 1% instead of 0% or something, but I've got no idea where.
(useless EDIT: Seems as if someone already fixed it in the newest version available in ABS since I changed it on my machine. Wait, trying...
EDIT: Nope, still only works up to 90% in current ABS version I think - might have just forgotten to re-extract the source of the panel after update. Redoing the "bad fix" got it to 100% again though.)
