Sound through headphones, but no sound from internal speakers

HP Pavilion dv6 Notebook running Windows 7 Home Premium
IDT High Definition Audio CODEC stwrt64.sys driver, version 6.10.6276
Intel Display audio IntcDAud.sys driver, version 6.12.0.3034

Hi,
Try the following.
First of all, shut down the notebook, unplug the AC Adapter and then remove the battery. Hold down the Power button for 30 seconds. Re-insert the battery, plug in the AC Adapter and start the notebook.
Next, download the IDT Audio installer on the link below and save it to your Downloads folder.
http://ftp.hp.com/pub/softpaq/sp46501-47000/sp46505.exe
When done, open windows Control Panel, open Device Manager and open up Sound, Video and Game Controllers. Right click the IDT device and select Uninstall - you should also get a prompt to remove the current driver, tick the box to allow this and then proceed with the uninstall.
When complete, restart the notebook and let Windows fully load. Open your Downloads folder, right click on the IDT installer and select 'Run as Administrator' to start the installation. When this has completed, right click the speaker icon in the Taskbar and select Playback Devices. Left click 'Speakers and Headphones' once to highlight it and then click the Set Default button - check if you now have audio.
If you still have no audio, open windows Control Panel, open Administrative Tools and open Services. Check that the following services are all showing as Status= Started and Start-up Type= Automatic
Audio Service
Multimedia Class Scheduler
Windows Audio
Windows Audio Endpoint Builder
If you need to make a change to any of the above, just right click the service and select Properties, then in the dropdown box next to 'Start-up type', select Automatic and click Apply to save the change. Then click the Start button.

For 1/11/11 expert day: can hear sounds on headphones but no sound via the internal speakers

HP Pavilion dv6135nr Notebook internal speakers have stopped working. I can hear sounds on headphones but no sound via the internal speakers. A search on HP customer care for my notebook yielded the download recommendation below, even though I had not stated my problem. However, executing this download did NOT resolve the problem. Please advise regarding resolution to inoperable speakers. I do not know if all of my sound and audio settings are correct, but the mute is not on and the volume controls are properly set. The default device is Conexant High Definition Audio output, per the sound and audio devices properties hardware tab the device status states "this device is working properly." Is it possible that a Skype or Foxfire update is in conflict with this device? If so, how do I resolve this situation?
Thank you.

Re: Fixes issue where the notebook speakers do not work after headphones or earphones are used for a while and then unplugged.
HOW DO YOU FIX THIS?? I cannot find the correct Microsoft Universal Audio Architecture (UAA) Bus Driver for High Definition Audio that works with my computer...
My computer:
VISTA
HP Compaq 2230s Notebook PC
Everytime I use my headphones for more than an hour or two, the **bleep** audio will not play on my notebook's speakers, just through the headphones. Usually restarting a few times resolves the problem, but not this time. If I knew that HP computers sucked this much I would never have spent so much money on this one!!!
Can you please tell me how to fix this problem once and for all? Thanks!!

When I plug in headphones no sound through headphones, but can hear music through ipod.

I plug in my headphones and no sound comes through the headphones, but can hear music from the ipod. Anyone have any solutions?

If you truly own an iPod classic, I'm not exactly sure how music can be heard playing from it, since it doesn't have an external speaker.
Have you tried a hard reset yet? To do this, press and hold both the Select (Center) and Menu buttons together long enough for the Apple logo to appear.
It might not hurt to try a different set of headphones as well.
The last resort is to restore the iPod to factory settings via iTunes and if the issue still persists, it's likely a hardware problem with the headphone jack.

Sound problems with Yosemite when switching from internal speakers to earbuds

After upgrading to Yosemite on my Macbook Pro, when I switch from using the internal speakers for sound and plug in my (Apple) earbuds, the sound stops working. The sound also stops when I do the reverse and unplug my earbuds, nothing comes out of the internal speakers. The only way to restore sound is to go into System Preferences, Sound, and select the output device (internal speakers, earphones, etc..). Anyone else experiencing this problem after installing Yosemite, or know of a fix?

I have the same problem..
there is something else happened twice with me, I plugged my macbook with a HDMI cable to the TV, and everything was ok, until I closed the macbook (sleep mode), when I opened the mac again,, the sound has gone! No sound from TV or macbook,, the only solution is to "RESTART"

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.

HT2494 2012 MacBook Pro - no sound from internal speakers, red light in headphone port

Mid 2012 MacBook Pro 15".
I normally use external speakers plugged into headphone jack.
The other day I unplugged the external speakers and when I re-booted my Mac, I got the start up sound
but I have no sound coming from my internal speakers. In System preferences sound output I see no entry for internal speakers.
I also notice a red light shining in the headphone jack port. I see on youtube that this problem is rather widespread.
Some suggest using a paper clip to try to turn the light out, but I am not doing that.
I have Lion installed, tried using the MIDI-app to reconfigure the speakers, but I only get sound if the headphones are plugged in.
Is this a software or hardware problem?
I have a genius bar appointment today at my local Apple retail store, and my mac is still on warranty but this
is troubling that you spend $2300 for a laptop and after a bit of regular use the internal speakers no longer work.
Any ideas?
thanks.

I agree Nick - it is a concern especially on such a basic function (sound) - Linc is right, the issue is microswitch, sounds like a bad design or a huge batch of sub quality switches, checking the forums this issue is common on MBP's.
Judging by the date and lack of further activity I assume you managed to get yours fixed at the genius bar ?
I finally fixed mine myself but posting reply for others who have same issue as this - however buyer beware folks, try this at your own risk !!!
The fix won't be liked by Apple Support, the genius bar, or the repair shops but it worked for me after over 12 months of using headphones / external speakers - WHAT A PIA !
Method -
Held Macbookpro on it's side with screen open and headphone/ audio port facing toward ground.
Took WD40 can with straw dispenser and placed straw inside audio port - sprayed 3 or 4 one second burst of WD40 into port.
Held MBP that way for 30 seconds giving MBP a shake to drain WD40 out
(I performed this whole excercise outside where the WD40 could drain out without an issue ;-)
I then took an old set of headphones and re-inserted / removed them from the audio port approx 20 times in and out with music playing on the MBP - intially when inserted music will only come from headphones then eventually MBP internal speakers start working !
I've tried everything else including the cocktail stick and bent pin inserted inside the port to try and free micro switch - nothing worked it was stuck fast.
As stated, can't endorse this for anybody else - you do so at your own risk - just stating this is what I did to get mine working again !

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?
To see which version of Windows you are using click here: Which Windows operating system am I running?
I look forward to your reply!
Let me know if this helps!

Sound from internal speakers keeps coming and going.

My internal speakers aren't working consistently. One second I hear sound and then the next I hear nothing. I checked "System Preferences > Sound > Output" and can see that the selected device keeps randomly switching from Internal Speakers to Digital Out to Headphones. Why is this happening, and how do I fix it?
Thx

1. Reset PRAM. http://support.apple.com/kb/PH14222
    Do this twice
2. Reset SMC.     http://support.apple.com/kb/HT3964
    Choose the appropriate method.

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.

Sound Through Headphones Stops

I have a Pavilion Dv7-6b01TX and recently I have been experiencing an issue where after a while, the laptop refuses to play sound through headphones, even when there's a pair of headphones plugged in. I've seen other problems like this, and the solution is to reinstall the sound drivers, but I have already done this 3 times. The only solution is to restart the laptop, but that is purely temporary and only lasts a couple of hours, at most.
Any help would be appreciated, Thanks.

I assume the guitar has electronics? If so, you must have some sort of ground loop. However, recording an acoustic using the electronics will not give the best acoustic sound, if that is what you are after. A mic on an acoustic will give a much more pleasing acoustic sound.
