Laptop rear speakers muted. Not showing up in alsamixer.

This is my second time around with Arch. I had this same problem before but I was able to Google the issue no problem, but I can't for the life of me find the right combination of keywords this time around. I'm sure someone will come in here and take 3 seconds to find it...
Anyways, like the title says. My rear speakers aren't playing any noise. Last time I am pretty sure that I just had to type in some command and then go into alsamixer to turn the volume up on the rear speakers, but when I use the 'alsamixer' command I can only see the "master" channel. I also installed pulseaudio but found nothing in the settings.
HP pavilion computer, using ALSA and and pulseaudio. I'm not sure what other information would be needed. If I there is some command I need to type in to list some info about my hardware/drivers please let me know and I will do that for you. I know this is an easy fix, and I did try to Google it myself before coming here. I just couldn't find anything that fixed my issue this time around.
Thank you.

It's considered obnoxious, as it's an empty post with no extra detail/troubleshooting -- also, asking if it's ok to bump with a bump makes the question rather redundant, does it not? Like knocking on a door and entering at the same time.
Hey, atleast I waited 24 hours. Now I know, thanks!

Hi lindaasw,
Welcome to the Support Communities!
Do you have the latest version of iTunes for Windows installed? I would turn on the sidebar and the menu bar just to make sure you are seeing everything. If the iPhone is still not recognized in iTunes, follow these troubleshooting steps:

Set up home sharing on PC and laptop but it is not showing the owner's library on laptop - on PC it has nothing in it? Has everything in the library above.

I have done everything it says to do however nothing is showing up on my laptop. It says Miss Kidds library which is the name of my user on the PC so I know it has recognised it. On my PC it doesnt have anything in the owners library under the shared box, not sure if this has anything to do with it? I have tried copying and pasting from my library to it and nothing has worked.

I purchased a movie for my last ipod nana on my last laptop but it's not showing up in my purchased items. Do I need to buy it again? Or what do I do?

I had my last laptop stolen with the movie on there along with my other itune purchases, but then I had to return my ipod nano bought a new ipod nano and I got back all my other purchases items(songs) but I didn't get my movie. I was wondering is there a way to get it back?

You should be regularly backing up. You will have to purchase again as there is no way to retreive a movie.

Sound - My built speakers do not show in the output section in sound system preferences area only digital out hence unless I connect external speakers I have no sound - can anyone assist?

on my IMac the internal speakers have ceased working - in the sound preferences area only digital out sound is there no internal speakers to choose so unless I connect external speakers I have no sound

Hey Jack (woofman jack)
Sounds like the micro switch inside the output jack that switches the audio from internal to external is stuck on external. Try plugging a set of buds, headphones or digital Toslink adapter in and out a few times to see if it will unstick the micro switch. You also might try jiggling a tooth pick around inside the audio output jack to see if that unsticks it? If not then you'll need to make an appointment at your Local Apple Store or Apple Service Provider and have the jack serviced.

My internal speakers are not showing up in output preferences

Head phones work fine. As soon as I unplug the head phones the sound icon goes from black to greyed out. The port works fine because if it was stuck it would not go from black to greyed out every time I plug and unplug the headphones. So the sensor is working and letting me know when the head phones are plugged in so please don't suggest a jammed port as an option. If it was stuck the icon would stay on constantly. When I look under system preferences>sound>output I only have headphones and Apple TV as an option. The internal speakers have disappeared from the list. When I reboot the macbook I get the familiar sound of the start up so I know the speakers work. I believe the problem started when we got Apple TV AirPlay but it could be a coincidence. Also I have been looking through the forums dating back to 2006 and have not found any thing that works. Thanks for any new information.

My laptop's speakers will not turn on, how can I fix this?

Hi all,
When i try to turn up or down the volume, I get an image, in the place of where the usual volume thing pops up, of the mostly the same thing, except the "sound waves" coming out of the speaker image are grey, as well as the speaker image itself, and below the volume level ticks is a cancel sign (circle with slash through it), and my speakers refuse to work!
However, when I plug in a 1/8 inch headphone/speaker cable, the signal does get sent to the speakers/headphones.
I've tried system prefs, to no avail, please help me figure this out, thanks!

The jack or the switch in the jack might be dirty. Try inserting and removing the external jack a few times. Sometimes blowing air into the jack works. Do not use high pressure. This seems to be a common issue on some computers.

No Sound on Rear Speakers

I have a new Lenovo H420and I am unable to get sound from the 2nd set of rear speakers when using a media player.
The OS is Windows 7 Home 64 bit and I have put in all new drivers for the Realtek HD Audio. When I run the Lenovo HD Audio Manager the system shows stereo or quadrophonic or 5.1 speakers. Stereo is fine and plays back on the front speakers. And when set to 4 speakers, the Audio Manager playback tests successfully on all 4 speakers. It does this also for the Windows speaker configuration.
But running Windows media player or VLC player will only play sounds on the front channel. I am unable to find any information from Lenovo, Realtek or Microsoft about this problem, but I can find lots of other people with a similar issue.
Any suggestions for a solution?
Solved!
Go to Solution.

This problem with no sound on rear speakers has taken up far more time than I ever expected. I have un-installed and re-installed drivers and assorted audio applications in an an attempt to resolve it. Internet research found many other people with the same frustrating problem with Realtek Audio and Windows 7. There seemed to be no one who had found a good answer.
HERE IS THE SOLUTION!
> Run the Realtek Audio Manager (aka Lenovo HD auido Manager) found in the control panel programs.
> Click Advanced button on right panel
> Set Speaker Configuration to Quadraphonic
> Click the Test button or click on the individual speakers. You should hear sound from all the speakers except for the center channel and subwoofer. This proves there is a signal for the front and rear speakers. The problem is that when running applications there is no sound on the rear speakers.
> Click Sound Effects tab, change the Environment from <none> to Room. There should now be an audio signal for the rear speakers!
Why this is not explained anywhere on Realtek help or anywhere else on the internet is a mystery. But at least this is an easy if baffling fix. I believe that the Realtek Audio codex wants to process all sound through some kind of effects and delay engine. There doesn't seem to be any Fade control for Front and Rear. There is a Loudness Equalization that I also clicked that does some voluime adjustment but not much. The Rear speakers will not play for many of the odd Environments, I found Room, Auditorium, and Concert Hall to be acceptable. Perhaps others like Sewer Pipe may be suitable for games. Most are just silly noise effects.
The equalizer has some useful qualities and can adjust the bass/treble audio to suit music. The Live was the best for my speakers which are Logitech. The sub-woofer may need some adjustment depending on the carpets or tile in the room.
Hope this helps someone to resolve this wierd audio problem.

Internal Speakers do not work at all

My sound was working just fine a few days ago, and all of a sudden, there is no sound at all comming from my macbook pro. I have tried plugging in headphones and still there's no sound comming from there neither. I don't even hear the chime at start-up. I have looked at a couple of fourms on here and tried everything from toggling with the headphone jack to reinstalling OS X Mavericks but still no dice. There's no red light showing up in the headphone jack, and the interna speakers are not showing up at all in sound preferences. I don't know what is going on, i have tried everything! What should I do? Do I need to buy a new sound system??

I'm having the exact issue. I, too, have done everything I know to do to correct it. I've never had a moments trouble with it until I update to OS X Maverick the other day. I sometimes plug my computer to my TV via a HDMI cable, and the sound plays through the TV just fine with that. The only thing left I know to do is to take it to the Mac Store....

Elements 5 - Organizer will not show thumbnails

Recently moved Elements 5 to my new laptop - On the laptop the organizer will not show photos in any view other than single picture. Anything smaller shows the hour glass [also shows on the collections icons]. I deleated the first catalog transfer and have been only using new photos transfered from my D-50. It will run full screen shows just nothing smaller that a single picture view. I also uninstalled and reinstalled the Elements software.
I have unchecked the filer checker.
Systems is a Vista home premium 64 bit, 4 gig of ram, Lenovo ideapad laptop 5800T processor. Version 5.0.2
Any ideas?

I can't be sure this is the problem, but ...
Is this the first time you have opened PSE5 on this computer? If so, it truly is generating the thumbnails. Your statement about how in single image mode the thumbnail appears is a symptom of this phase of the operation. Just let it run. It will finish, and the problem will be gone.

Songs downloaded on iphone not showing up on mac with match

I have itunes match. I recently downloaded a couple of songs on my iphone 6 and even though I am updating match on my mac laptop, the songs are not showing up on my itunes library on the computer. I have not had this problem before.

Hi rlubarsky9,
Thanks for using Apple Support Communities. Based on what you stated, it sounds like songs are not showing up in the Mac. I would recommend that you read this article, it may be able to help the issue.

My money is on your document window being off screen.
At some point you may have had a secondary monitor attached which you have since disconnected, or you drastically changed your monitor resolution.
Trashing your preferences should fix it instantly:
To re-create the preferences files for Photoshop, start the application while holding down Ctrl+Alt+Shift (Windows) or Command+Option+Shift (Mac OS). Then, click Yes to the message, "Delete the Adobe Photoshop Settings file?"
i tried this but i did not work. (however i do work with diferent screens)
thanks already for you efforts

Bridge does not show VC status in Thumbnail

Hi,
since migrating to a new laptop, Bridge CS3 does not show the VersionCue status icons under the thumbnail, only in the inspector panel. I cannot find any hint in the docs how to get the status icons shown again. Any ideas?
Cheers
Thomas

Being able to see at a glance which files are checked out/by whom below each thumbnail would be infinitely valuable, and is therefore not an option in Bridge Thumbnail Preferences. :)
If you enable Tooltips in Thumbnail Preferences, the Vc status is shown there, but one still must click or hover over each and every file to get the real Vc status. And of course, as you pointed out, the Vc status is always available for individual files in the Inspector Panel.
