No sound with internal speakers

My HP dv1660se P/N et732ua laptop does not have internal speakers working? Head set works but not with DVDs, no sound at all. I just installed Windows 7 32 bit.

Hi Kubotaboyz,
Welcome to Lenovo Community Forums!
The Lenovo K450e does not come with an internal speakers.
All Lenovo Tower PC does not have an internal Speaker and you must connect one either through the back Audio port or at the front on some units.
You can check this K4 Model series Maintenance Manual to verify that the unit does not include speakers internally.
Hope this helps

10.4.10 Audio Popping Issues: Information Check with Internal Speakers

For people with internal speakers, or those without subwoofers: Please read all the way to the bottom to find a test that will determine whether you are also having audio problems, even if you can't hear pops.
We've had a lot of discussion about audio popping due to 10.4.10, and the evidence indicates that the audio circuitry is going to sleep to conserve power, even on AC-only computers like the iMac, Mac Mini, and (at least one) Mac Pro. Some people claim to not have this problem, but I'm wondering if they just aren't noticing it.
Having external speakers with a subwoofer, set to high amplification, are key to obvious detection of the problem. Let the sound subsystem go idle for 30+ seconds (wait a minute with no audio, just to be safe), turn up your external speakers really loud, and cause the computer to make a sound. You should hear a burst before the sound plays. If you repeat the sound, you won't hear the burst. This is the sound of the audio circuitry powering on, and the speakers are amplifying it.
About 30 seconds after the sound finishes playing, if you leave the volume of your speakers turned way up, you should hear a "pop" as the circuitry is powered off. Then, playing another sound will recreate the burst.
I haven't been able to hear these sounds with internal speakers, either on the Mini or iMac. But the problem still exists, and it is detectable... if you know what you are looking for.
The burst of the audio circuitry turning on also causes a delay in the audio. The delay is a noticeable fraction of a second, an it can easily be detected if you have a repeatable source of sound. I like Terminal.app, because I use that application all day, every day. Here is how you can check to see if you are also subject to the audio problems:
1. Start Terminal.app (in the /Applications/Utilities directory).
2. Wait one minute for the audio circuitry to shut down.
3. Without typing anything else, very quickly strike and release the Backspace key.
4. If you pressed the key all the way, the program should have caused a beep. However, if the audio circuitry goes to sleep, the beep should occur after you have moved your hand off the key. This is because the circuitry takes time to power itself on before playing the sound.
5. Now, quickly strike the Backspace key again. You should notice that the sound is produced immediately as you hit the key, without the delay you just witnessed.
6. Strike the Backspace key repeatedly, to confirm that there is no audio delay. Do this about once every second or two. If you press the key too rapidly, not all of the presses will produce sounds... this behavior is not related to the issue we are testing.
7. Wait another minute for the audio circuitry to shut down, and strike the Backspace key once more. You should again observe a delay between your strike and the sound production.
If you witness delays like this, your audio circuitry is also going to sleep, and you are having the same audio problems as the rest of us. However, either because you are using internal speakers, or because your external speakers don't have the appropriate response, you aren't hearing the same bursts and pops as the rest of us.
Please try this test, and report here. I want to build a list of people who previously couldn't hear the sounds, but still have the delay. This might give us a better picture of the scope of the problem.

Re: 10.4.10 Audio Popping Issues: Information Check with Internal Speakers
Your analysis of what is happening is right on.
The problem on my Intel Mac mini with external Klipsch speakers (two mid-range/high and a subwoofer) is REAL obvious as the system emits a hum like a Spinal Tap amplifier turned up to #11 when 10.4.10 powers down the audio circuitry
Then, if I play a song in iTunes, it first pops and the hum disappears right before playing.
Quite annoying.
Here's what I sent to Apple tech support:
Guys/Gals (OS X Engineers):
Concerning the Snap, Crackle Pop Audio problem in the 10.4.10 update:
Please. Just do the right thing and fix the audio.
There is no need to power cycle the audio subsystem to save .0005 amps on your laptops.
And then to make your Mac mini/iMac/other desktop users have to put up with it when using AC power is ridiculous.
Put the audio subsystem back like it was in 10.4.9 and let the laptop battery freaks looking for mini-amp savings get a "work-a-round".
Crikey!

Problem with internal speakers of MacBook Pro

Hi,
I wanted to know if anyone have experienced a problem with internal speakers of Mac Book Pro. In my MackBook the Internal speaker volume goes down automatically. I checked the System Preferences>Sound>Output , from there I check that it is in the middle ( Balance) However, the problem is still the exists. Just for testing I played an audio file and I moved the bar toward the right speaker it is the same and when I move toward the left speaker the whole sound goes off . Looks like one speaker stops working completely. Then I checked the Utilities > Audio MIDI Setup > Configure Speakers from there I checked both left and right speakers and the channel frequency is fine. Still same issue. I have no idea what is going on , I really need your suggestions to get this fixed.
Thanks in advance.

My mac desktop will not provide sound from internal speakers. When I go to audio devices window it only shows airplay. How can I get internal speakers back.

There are many possible causes for this issue. Take each of the following steps that you haven't already tried. Some may not apply to your model. Back up all data before making any changes.
1. Start with the steps recommended in this support article. Don't skip any of the steps. It's the starting point for further efforts to solve the problem.
2. Run Software Update and make sure you have a fully up-to-date installation of OS X.
3. If you've installed an application called "Memory Clean" or any other third-party software that is supposed to "clean" or "purge" memory automatically, remove it according to the developer's instructions and restart. You should do that even if the software is not causing the problem, because it's useless.
4. Other third-party software that has been reported to interfere with sound output includes "Boom" and "Samsung Kies." If applicable, uninstall according to the developer's instructions (not by dragging something to the Trash.)
5. If an AirPlay device is selected for sound output from iTunes (or from other applications via third-party software such as "Airfoil"), deselect it.
6. Launch the application "Audio MIDI Setup" by entering the first few letters of its name in a Spotlight search and selecting it in the results (it should be at the top.) Select Built-in Output from the list on the left. If the Mute boxes are checked, uncheck them.
7. If a red light is visible in the audio-out port when sound should be playing, the internal switch is stuck in the position for digital output. You may be able to free it by inserting and removing a mini-stereo jack of the proper size. Inserting any kind of tool in the port may cause damage that won't be covered by your warranty.
If there's no red light, the switch may still be stuck in the headphone position. Try to free it the same way.
8. Disconnect all wired peripherals except keyboard and mouse, if applicable. If more than one display is connected, disconnect all extra ones. Restart and test.
9. If you have a MacBook Air, turn off Bluetooth and restart.
10. Start up in safe mode. Don't log in; just restart as usual when the login screen appears. When you do, make sure the words "Safe Boot" do not appear in the login screen. If they do, the system is still in safe mode and sound won't work.
11. Reset the NVRAM.
12. Reset the SMC.
13. Triple-click anywhere in the line below on this page to select it:
/Library/Preferences/Audio
Right-click or control-click the highlighted line and select
Services ▹ Reveal in Finder (or just Reveal)
from the contextual menu.* A folder should open with an item selected. Move the selected item to the Trash. You may be prompted for your administrator login password. Restart the computer and empty the Trash. Recreate your settings in the Sound preference pane.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.
14. Reinstall OS X after backing up all data.
15. Make a "Genius" appointment at an Apple Store.

No sound from internal speakers or headphones when using ART Tube interface

Hi - can anyone help with this...
I have no sound fromthe internal speakers or headphones when using my new ART Tube USB interface - I get a nice loud recording level from the ART but cant monitor - in Logic 7.2
Audio hardware interface in logic 7.2 is set to USB Codec - just like the ART manual states
And the SOUND control panel is set to speakers/headphones
But no love...
Any comments welcomed
Si2

By default, OSX will only let you have one interface active at any one time - so if you specify the ART as your interface to get sound in, you don't have access to your regular interface to listen to it.
But there is a workaround - open the Audio/MIDI Setup utility, create a new "Aggregate Device", and add both your required audio interfaces to it.
Now, back in Logic, select the aggregate device you created as the audio device, and now all your inputs and outputs from both interfaces are available - the aggregate device acts as one big interface containing both your hardware interfaces.

No sound from internal speakers in HP Mini

i can't hear any sound from internal speakers although if i connect headphones or external speakers i can hear sound!

Hello @Landon3400 ,
Welcome to the HP Forums!
I understand your notebook only has sound, through your headphones.
Try updating the driver with the following download and tell me if it resolves the issue: IDT High-Definition (HD) Audio Driver.
Furthermore, check out this thread that has a lot of great suggestions for issues with no sound: Troubleshooting Guide: Audio does not Work after a Certain Period of Time and this document for no sound in Windows 8: No Sound from Speakers (Windows 8)
It would help to know which product and operating system you are using.
For information on finding your product and model numbers click here: How Do I Find My Model Number or Product Number?

No sound on internal speakers but OK on external ones G4 15" 1.75 Ghz

I have no start-up chime or no sound from internal speakers, but do have sound when I plug in an external speaker. Is there a sound board in this unit, or is it a logic board problem? Also have the no wake-up after sleep issue, and have to remove all power - have read about 127 posts on this, and one consensus seems to be that removing the trackpad sensor will solve that problem. Does that not have any effect on the operation of the powerbook, and if not, why is there a trackpad sensor in the first place?

It is good that external speakers work. It effectively narrows down the problem to the switching contacts in the headphone jack, as other faults are very rare. I would insert a plug in and out of the headphone jack many times and wiggle it.
I have no experience with the failure to wake problem.

Very poor sound from internal speakers, very good on headphones.

Hi,
I hope you can give some advice.
New to all this so apologies if protocols are broken etc
New 20" imac, running Leopard.
very thin, tinny sound from internal speakers (similar to hearing someone's else's walkman
on the train). when I plug headphones in its great no probs.
Advice please! I don't want to send it back I'm halfway through my assignment.

I just realized I've never heard the internal speakers on my new iMac, I have always used good 2.1 speakers since I got my eMac years ago and the internals really sucked.
I was just curious, have you heard anybody elses built in iMac speakers and did they sound better than yours or the same? Maybe at the Apple Store?
I don't know, I just didn't know if they really improved them. Maybe other iMac users can chime in on internal speaker quality. The only reason I said all this was because you mentioned that headphones sound great, which is the same port that a set of external speakers would go.
Sorry to hear you had to send it back for that. Here's hoping you didn't have to send it in for what the speakers really do sound like.

Sound from internal speakers on iMac not working

I've been having a recurring problem where the internal speakers constantly lose connection. When I go to sound preferences, the internal speakers disappear from the device list in the output tab. I've also noticed that plugging in my own headphones does not solve the problem, sound is still lost and regained. I have no idea what is causing this. I am currently working on the current software(Version10.9.4).

Here is one that worked for another user it may work for you
ObiJuan2080Sep 3, 2012 2:02 PM Re: internal speakers no sound
Re: internal speakers no soundin response to noondaywitch | This solved my question
Here's what worked for me. It's not a workaround, this acutally solved the problem and I haven't had speaker issues since.
Go to "Activity Monitor" (you can hold "Command" "Shift" and press "U" if you're on the desktop).
Locate "coreaudiod" under "All Processes"
Right click it and click on "Quit"
After several seconds, "coreaudiod" will restart on it's own and your speakers will return to normal.
I tested this by restarting to see if it was a fluke workaround. Then I turned it off and waited a day (I had things to do so the waiting a day was easy lol). Turned it on, it was fine. I put it on sleep mode, waited 10 mins. and took i off of sleep mode. It was fine. Everything went back to normal for me.
Let me know if this worked for you.
Good Luck and Cheers

Sound heard through headphones, but not with internal speakers

Recently, my computer stopped producing sound from the speakers. However, I plug in headphones and everything can be heard. I've already checked Sound in System Preferences. Nothing is muted and all sliders are in the correct position. In the Output Pane, my only option for the output source is headphones, no internal speakers. What happened? What should I do?

I recently got the same problem. Its not that bad but confused me at first. If that is the worst problem you get with your computer consider yourself lucky. You could bring it by an apple store genius and see what they say but its most likely a switch problem like tteuer said. If my memory serves me right that switch is connected to the logic board, if you have it still under warranty, great, if not, you might as well get another laptop if it really bothers you.
Tip: I have made it work by either slowly removing the headphone from the jack or rotating it. If that did not work the first time I repeated it.

Problem with sound from internal speakers

I have rescued an 867 hz TiBook from the trash heap. This machine was being discarded because it wouldn't wake up (just did this red, blue, yellow flashing thing, so it had to be restarted everytime it went to sleep) and because the internal speakers had stopped working. I took off the keyboard and flashed the pram, reset everything, wiped the hard drive and installed Leopard. This seems to have fixed the sleep issue but there is still no sound from the speakers.The headphone jack works fine, the built-in mic works and there IS an option for internals as the output in prefs, so it's not the headphone jack problem I've read about. I've searched and searched but I can't seem to find a solution that works... anyone have any ideas?

Hi Mr. Waters,
Welcome to Apple Discussions.
You may want to at least follow the wires back from the speakers and see that they're connected, but it's likely the sound card which is unfortunately soldered onto the logic board. If so, the repair would mean replacing the logic board, rather expensive and not easy. Still a nice find for free.
