[GOT AROUND] No more volume control in lxpanel

Hello
I'm using Arch Linux with lxde and openbox, installed on USB pen (it's a persistent install, not a live one). My filesystem is ext4.
Since last filesystem update (following the home page of the wiki) the 'Volume Control' button of lxpanel is disabled, although the sound still works as it always did. If I right-click on it, in order to parametrize it, I get this message:
Error, you need to install an application to configure the sound (pavucontol, alsamixer ...)
The point is that alsamixer IS installed, and I can use it to increase/decrease the volume.
I tried to remove/re-install alsamixer: no change. I also killed lxpanel and restarted it from the command line, in order to check if I received some more enlightening error message: I got nothing.
Any hint?

Hello Lone_Wolf
Thank you for your reply. I removed lxpanel and installed fbpanel instead. Bad luck! The volume control of fbpanel doesn't work either, and moreover it prevents fbpanel from starting.
$ fbpanel &
(fbpanel:1312): Gtk-WARNING **: Theme directory of theme Azenis Icons has no size field
volume: can't open /dev/mixer
fbpanel: can't start plugin volume
[1]+ Termine 1 fbpanel
The point is that /dev/mixer doesn't exists. I have seen a bug report on this problem, which is open since... 2010-11-28! Well, I suppose that reporting a bug on lxpanel and being patient is probably the only thing to do. I'm going to close the subject.
Nevertheless it is strange that it occured to me with lxpanel only recently. Strange also that I'm the only Arch user experienceing this problem. Would it be possible that other users don't experience it because for some reason they do have /dev/mixer file? May I solve it by creating a link /dev/mixer pointing to some other sound related device? Advices welcome...
Regards,
LuX

  • Front Row 1.2.1 No More Volume Control

    Installed Front Row 1.2.1 on my iMac G5 iSight through Software Update, along with the other updates, and repaired permissions afterwards. The volume cannot be adjusted using the keyboard arrow keys or the Apple Remote. When + or - is pressed on the remote, the volume slider appears, but now the volume is on maximum, and cannot be adjusted. This is not limited to iTunes, it also occurred when playing QuickTime movies. The regular volume keys on the keyboard continue to adjust the main system volume, but we now lost the remote volume control. Hopefully there will be a fix soon.

    Solved my own problem through troubleshooting. The HK SoundSticks were the problem. When I got the new iMac G5 iSight, they worked great. Somewhere along the lines, the HK's got confused and my sound preference pane said No settings for this output device.
    Browing the discussion boards, this has been a known issue...but the cause is difficult to determine.
    If I boot from my external FireWire, all is well. The internal iMac drive, problem. Something could have happened with the migration from my PowerBook to the iMac, or a system update caused trouble.
    I tried the quick solution...changed USB ports. Problem solved. The balance control is back and Front Row can control the volume once again. Bizarre, isn't it?

  • 3.1.3 upgrade no more volume control

    Just upgraded OS on 1st gen touch and now there is no volume control bar. tried reinstalling 2 times with no result. anyone else have this problem or a solution?

    I had the same problem. Had no problem prior to updating with 3.1.3.
    I was finally able to restore my volumn (without having to use headphones/earbuds) by resetting the unit. Simply hold down the top button and menu button at the same time. It will shut the unit off. Then, hold them down again until you see the apple symbol. Wait a few moments and the unit comes back on. My volumn was then working again. Hope it works for you too.

  • No More Volume Controls?

    I just upgraded my iPod Touch to 3.0 and love it, but when I went to listen to music, there were no volume controls. There is no setting to enable volume controls. When I double click the home button, it says "Dock Connector" where the slider would usually be, but I don't have anything connected to it. I have an iPod Touch 1G. How do I change the volume?

    Maybe you don't need the volume controls for your speaker dock system, but that is not universally true. My speaker dock system sounds better at a certain internal-volume level, and that level is different than the level I prefer when using the earbuds. Being able to change it only when the earbuds are connected is an unacceptable consequence of a paid upgrade.
    Yes, I've already utilized the feedback link. And I also intend to let the manufacturer of the speaker system know that Apple's shortsightedness has hindered my enjoyment of and lowered the value of their product.

  • My kid dropped my iPad 2 and the volume control on the side got jammed in and now everytime my ipad is on the volume icon in the middle of the screen will not go away.  I can not move the switch on the side, it is jammed, is there a way to fix it?

    My kids dropped my iPad and the volume control on the side got jammed in and it will not move, how can I fix this?  Can it be pulled out to unstuck it.  The glass got chipped right next to it, but it is not that noticible.  Everything else works on the iPad, but the other problem is that I am past my 90 day warrenty and it will cost me $265.00 to have Apple fix it.  Is there anyway I can save my iPad?

    Your warranty is actually one year - the 90-days is only for free telephone support - but the warranty would not cover damage due to the iPad being dropped. I doubt there's anything you can do to fix the rocker, so you'll probably need to pay to get the iPad exchanged (by Apple) or repaired (by a third party repair service).

  • IPad 1 on iOS 5.1.1 I want the volume control in my iPad to more linear than logarithmic.

    So I have this iPad 1, and I just recently noticed that the volume control is very quiet throughout most of the range of the volume control and it suddenly gets very loud near the top end of the slider, is there any way to make this change a little more distributed over the entire slider action

    Hi Steve,
    I guess I'm confused.  Are you trying to sync with match? or is match off?
    If you are trying to sync with match on then go to settings>music> and make sure that the show all music toggle is turned on.
    If you are trying to sync with match off and are trying to put files onto your phone without usiing match then uncheck the music tab under your phones information on your computer and then let it sync and take everything off.  Then recheck the music box under the music tab and go to your summary page and make sure that the box that says sync only checked music is selected and resync.  Sometimes you have to take everything off before you can get it to resync and put stuff back on.
    Again, if you talking about what you see with match turned ON, on your ios device then make sure that the toggle for show all music is turned on.
    You cannot sync with your computer and itunes match at the same time.  You have to do one or the other.
    Please let me know if I misunderstood your question or did not answer it properly.

    I just got an iphone 4 yesterday. I got everything all set up and working great. When I woke up last this morning, my ipod has no sound and the albums covers are all mixed up. I've checked all my settings and volume control. My text sound won't work either. However, my ringtone works just fine.

    Have you taken the steps recommended in the User Guide:  restart, reset, restore?

  • More finegrained audio volume control? (Harman/Kardon USB SoundSticks)

    Hi,
    I've been asking this question for every major release since 10.2 and I am near to just give up on it. I use the Harman/Kardon SoundSticks (the older USB model, not version 2 with the regular audio jack) and since 10.2 they are simply too loud. Since the speakers themselves do not have any volume control knob it has to be a software solution.
    With OS X's sound volume keys I can only use "1 bar of volume" when in front of my Mac and even that is too loud. The only solution is to turn it off completely or to lower it a little bit via the volume control slider in the menu bar. This results in approximately "3/4 bar of volume". Moving it just a tiny bit down from here results in muted audio.
    Is there any way to just reduce the overall audio volume via software? Sure, I can do it app by app, but I really need a systemwide solution!
    Thanks
    Björn

    Then maybe you're really lucky or just like the high volume setting. This problem exists for years now and it's definitely not caused by my hardware/software. It was the same with the following Macs:
    - Power Mac G4
    - iBook G3
    - iBook G4
    - Power Mac G4 Cube
    - PowerBook G4 Ti
    - PowerBook G4 Alu
    - MacBook Pro CD
    - MacBook Pro C2D
    And it happened on all releases of OS X from 10.2 up to 10.5. All versions were installed clean without upgrading so I really have reason to believe it's Apple's sound driver for the SoundSticks...

  • Right-click on Magic Mouse and Volume Controls on Wireless keyboard suddenly stopped working

    I am running Mavericks 10.9.2 on an Late 2012 iMac.
    One morning the right click on my Magic Mouse and the volume controls on the wireless keyboard stopped working.
    These mouse and keyboard themselves seem fine; they work okay ehn used on a MacBook.
    Everything else about the mouse and keyboard is fine.
    This seems to be a problem what has been around for a whole, with a wide variety of solutions.
    I have read
    https://discussions.apple.com/message/16799039#16799039
    https://discussions.apple.com/message/23474052#23474052
    https://discussions.apple.com/message/19660884#19660884
    and have tried
    Clicking on and off the 'right click' checkbox in the Mouse System Preferences - No effect
    Deleting /Library/Preferences/com.apple.Bluetooth.plist - No effect
    Restarting in Safe Mode - When starting in safe mode, the computer crashes out and restarted
    Resetting NVRAM / PRAM - Is it CTRL+CMD+P+R or CMD+OPT+P+R ?  Neither work for me (I do try it using a wired keyboard, but never get the double chime)
    Upgraded to 10.9.2 - no effect
    Moved the /System/Library/Extensions/AppleHIDMouse.kext and AppleHIDKeyboard.kext and and back in (and re-authenticate) - No joy
    Moved the /System/Library/Extensions/AppleHIDMouse.kext and AppleHIDKeyboard.kext from a working MacBook on same OS - Made the keyboard misbehave even more
    Has anyone got any other cures for this?
    Thanks in advance.

    Here is what worked for me.  My scrolling on the mighty mouse and a few buttons on my wireless keyboard weren't working properly.  I reset the SMC, a link explaining the process is below.  Hope it helps you too!

    I'm using a macbook pro, running snow leopard. Yesterday I got around to emptying my trash for the first time in quite awhile and was surprised by how much there seemed to be in there. Immediately after a question mark symbol appeared on all my hard disk folders. If I click on these question marks I get a message saying ' the item can't be found'.

    Not sure where these hard disk folders are located that you are referring to?  Finder, Finder tool bar, Finder side bar, Desktop, Dock? 
    More then likely they are  an alias that not longer point to the orginals,  thus the question mark.
    I would reboot.  Delete icons if an alias and just recreate by dragging from the source. Try right click (control) click to remove.

  • How do I set shortcuts on my new onn wireless keyboard for volume control?

    Replacement Keyboard
    Volume control issue with a non- Apple Keyboard 
    [Sunday - July 29, 2012 - 2:18pm]
    Question:     I just purchased a new keyboard in place of the orginal for my iMac which gave out this morning. The brand name of the keyboard is
    ONN & it's a wireless board. I've encountered an issue that is a deal breaker - if there is no possible way to correct it. The volume control buttons used to
    increase/decrease/mute the volume do not work on this product. I bough this keyboard because it was one of the two that was Mac compatable at my
    local store. I realize you get what you pay for but hope there is a soulution!   
    **Sidenote: I was curious, anyone had any other issues with these keyboards?
    Some additional information:
    When I woke up this morning, sat down in my computer chair, turned on my iMac and pulled up Textedit. I placed my hands on my faithful keyboard and within moments I realized that it had met it's end. I was quite upset that my original, sleek white iMac keyboard was now a thng of the past but realized that I'd need a replacement very soon in order to get my paperwork done.
    Unfortunately, I did not have time to ride forty-five minutes to my local Apple store and I didn't neccesarily want to hand over the cash for one of the pricey keyboards at the time because I am going on a vacation within the next few weeks and each dime counts. So, I decided to visit a store that obviously would have the cheapeast deals in the meantime. So, I headed to to Wal-Mart to make a quick purchase
    As I walked the aisles it soon became evident that today's market still is not on point when it comes to having Apple compatable hardware, softwore or anything for that matter. As I quickly skimmed the keyboards I ran across several that caught my eye, but of course, they were all made specifically for Windows. So, finally I approcahed two keyboards that were Mac compatible. The first was way too large and came with a mouse, which I did not need. The second caught my eye and I knew that this would be my purchase.:::
    The verdict: an onn wireless keyboard that was both affordable and also gave off a sleek and modern apperance. (Retailed: $24.00)
    So, I got home and began using the board. For the first how I was actuallly very satisfied. I like the buttons and the feel of the board. Then, I encountered a problem that made my interested for the new keyboard vanish.
    The Issue:  On the boards layout, the (F2) key has a symbol that notates the decrease volume control button, (F3) of course would be the increase volume button & lastly the (F4) button represents the [mute] button.
    However, these buttons don't work. Sadly, I am not aware of how I could possibly change this issue or if it would even be possible. I sincerely hope that it's possible - because I like the convience of the volume control keys - they were actually my favorite part of the keyboard. Manually changing the volume by going through system preferences does not sound fun to me once so ever. I guess you could call me spoiled but I don't think I can even keep this board if it doesn't have the ability to change volume/mute via the keyboard.
    This is a shame because the keyboard it'self isn't bad at all and I actually somewhat like it. So, if you have any information or an answer to this question - I'd truly appreciate hearing your responses! Also, do keep in mind I am a rookie when it comes to computers as a whole so try to simplicate things for me if that is nessecary.
    Closing negative note on this keyboard: As I typed this I started encountering a very annoying problem. As I am typing in a line, forming a sentence the keyboard would randomly start typing in pargraphs above and below as well. I'm not sure if this is something that I caused by pressing too hard with my hands or if this is a deffect. Either way, I will saving my receipt and the boxing for this product until I hear further news.
    I hope to hear from you soon and I appreciate your help very much.
    Have a great day,

  • Ipod Touch Gen 1 and   3.1.3 volume control

    Im pretty annoyed at the latest firmware upgrade, the completely removes onscreen volume control. and the ipod touch 1st generation has no side buttons for it, making this now impossible for me to change without going into an app that has volume in it.
    Before it was bad enough because I could not double click my button to enter the volume control/song change quick menu unless music was already playing, but I got around it.
    I'm pretty disappointed with apples lack of support for earlier versions. Not only that, but I can find absolutely no feedback forms for anything other than itunes and the website.

    I seem to recall that this issue only exists when there is nothing plugged into the headphone jack -- if you plug something in then you should have volume control. I guess the problem would be if you use an FM transmitter, is that the case?

  • I have lost sound on my iPad in apps unless I use headphones ,does anyone know how to get sound back without them .I have used the mute volume on the bar at bottom of screen and the slider volume control there only shows when headphones are plugged in !

    I have lost sound on my iPad in apps unless I use headphones ,does anyone know how to get sound back without them .I have used the mute volume on the bar at bottom of screen and the slider volume control there only shows when headphones are plugged in !
    I also tried resetting settings all to no avail ...I looked up some advice and watched utube video advice on how to fix without success..
    The volume control button on side does not work ,I got the iPad last August and wonder if it is a fault that means I must return it for replacement from where it was purchased ?

    The Retrospect you used way back when is no longer around. The company was sold and that company produced a new version of Retrospect - Retrospect 8.x
    So, as you've been told, you would have to be running a Tiger system with an old version of Retrospect software (5.x or 6.x - you would need to know) assuming you can find the software.
    As best I can remember you cannot extract files from a Retrospect backup except using the software since Retrospect did not normally make a file by file backup rather it created an archive of the files in the backup. I'm assuming that the EMC/Retrospect people have told you that old Retrospect backups are not accessible by Retrospect 8.x?
