Hi @SNJY ,
Thank you for visiting the HP Support Forums and Welcome. I have looked into your issue about your HP Pavilion dv9730us Notebook and not playing sound. Here is a document on troubleshooting sound. Please remove the headphones for troubleshooting.
Here is another step to try.
1. Right click speaker icon (right hand corner)
2. Select Playback devices
3. Right click Speakers
4. Enable it and set as Default
5. Click Apply/Ok 
 A windows update KB2962407 could have caused the no sound. Open windows Control Panel, open Windows Update. Right click it and select Uninstall.
Hope this helps resolve the sound.
Thanks.

  • Win8/T500 headphone jack stopped working. Conextant Audio Software issue?

    I have a T500 - 2081CTO, and in the last week or less, the headphone jack has stopped working. There was a windows update recently so I'm assuming that's the culprit. I typically let it do it's auto-update thing without paying much attention, so I don't know what exactly changed or why it would kill the headphone jack. I've tried looking for Conextant drivers, but those don't seem to have changed since 2011. Win8 and the T500 has always been a bit flaky, but this at least has always worked. How can I test that it's the software and not a hardware issue? And if it is software related, what do I need to fix it?

    I now think that it's possible there wasn't a "problem" so much as an inconvenience. While at home, I incrementally re-installed everything that I still wanted and saw no problems with the headphone jack. However, once I returned to work and connected the laptop to my dock with USB speakers, the USB always take precedence. Previously, the computer would recognize that headphones were plugged in and switch from USB to internal (ie. headphone jack) as default, and switch back to USB when the headphones were removed, always skipping the on-board speakers. That ability now seems to be missing and I need to manually set the internal speakers as default whenever I plug in headphones and manually back to USB when they're removed. Is there any way to get this functionality back? I loved how it "just worked" before. Now it's "just broken".

  • No audio from speakers or jack. Sound bar shows audio activity. All drivers updated. HP G62.

    I cannot get audio from the speakers or audio jack. All drivers updated, realtek, BIOS F37.
    There is activity on the windows sound bar (green level moves) when music is played, however no audio is executed.
    HP Support Assistant software was installed, but no detection of the problem.
    No warranty since March 2011
    I will deeply appreciate any support or guidance to solve this problem. Thank you very much in advance.

    Hi vc329,
    Doesn't sound like encouraging news, though it is odd that the sound came back for a short while at least.  If you still haven't rebooted the PC since putting it to sleep and loosing the sound, then I would suggested going ahead and rebooting or even doing a full hard reset (power down, remove the AC adapter, remove the battery, hold down the power button for 20 seconds or so, then reconnect the AC power and Battery and boot up) to see if the sound can be recovered again.
    If the sound still doesn't work, Check Device Manager to see if the sound driver still looks OK, make sure you are using the latest driver again (it looks like the latest driver is 6.10.6381.0), another option might also be to try the older driver that is still available from the site, or try recovering the original driver shipped on the PC.  The steps to do these things are covered in the document listed below, in Step 6 (Restoring the Audio Driver), Step 7 (Updating the Audio Driver), and Step 8 (Checking Device Manager):
    No Sound from the Speakers (Windows 7)
    If none of that seems to help, I'd recommend testing the hardware using Step 9 in that document.
    If the online warranty check sees you as out of warranty, you may still be OK if you have the original proof of purchase (receipt) from wherever you purchased the PC, but you may have to provide it when calling HP for service if the sound can't be fixed.  If you are close to the end of warranty I'd recommend calling customer care for your area (I assume you are still in Asia) and validating the warranty with them as soon as possible just to make sure.

  • Cq50-142us windows 7 64 bit headphones work but no sound from built in Altec-Lansing speakers

    I recently installed Windows 7 64 bit on my CQ50-142US after the hard disk died.  I've installed all the drivers that apply, and in particular the Conexant driver for the built-in audio parts.  The system has built-in Altec-Lansing speakers.
    I get no sound from the built in speakers, but if I plug in stereo headphones to the front-panel headphone jack, they work and they produce stereo sound no problem.
    I can't see any way to test the speakers.  If the system has any built-in diagnostic capability, I can't find it. 
    A Google search suggests I'm not the only person with similar problems.
    Suggestions?

    You can isolate this issue to a hardware or software fault by running a live distro of Ubuntu linix. See step number 2 to install it to a USB memory stick.
    If the device is not recognized by Ubuntu during its config operations that the probem is likely to be with the notebook's system board.
    Is your notebook still within the standard one year warranty period?

  • In v.11, how can I capture video but not audio from a camera?

    In v.11, how can I capture video but not audio from a camera?

    Rodney
    I see what you mean....Premiere Elements 10 appears to be the last version that had options for the user to select Capture Video and/or Audio in the its Capture Window.
    If you are doing DV data capture firewire into the Premiere Elements 11 Capture Windows and want a final file without audio and you cannot do this at the camera level, then consider....
    1. Do the Capture "to the Timeline" - video linked to audio result on the project's Video Track 1
    a. Right click the Timeline DV AVl and select Delete Audio and then edit accordingly.
    or
    b. Import the DV AVI but, when you go to export it, in the export settings, remove the check mark next to Audio so that the export contains only the video portion.
    Publish+Share/Computer/AVI with Presets = DV NTSC Standard
    Please let us know if any of that worked for you.
    Thank you.

  • Acer Liquid E700 problem with headphone jack, not working properly.

    Here I am again, what a surprise! Reporting another problem with my 2 month old ACER LIQUID E700. Now the problem is, the headphone jack isnt working properly. When I watch movies, or play music with a headphone or earphone, the dialogue or conversations during movies , or the lyrics sang when playing music, can barely be heard. Also , everytime I connect my earphone it the E700, theres a fast ticking sound, which is faint but you can really hear it, and thats when I realized something was wrong. P.S This phone was never dropped or gotten wet. Im really starting to regret buying an acer phone.Any acer representatives out there who know whats going on?

    Well airstrike2014, I do know how it happened to me, it's weird but definitely how it happened, so I was downloading a electrical razor app to scare my friends (I know, it's stupid, but anyway) and the app works by vibrating at full power and playing a electric razor sound, but it would only vibrate (and the app description said that it would make some sounds too) and I tried maxing out my sound but there was really no way to make it play any sounds. I got tired of it 5 mins later and uninstalled thinking the problem was in the app or something, but I go watch a YouTube video right after and no sound was coming out either, even with the volume maxed out and with headphones, so I restart my phone, now sounds play perfectly when there aren't any headphones plugged in but when there are, it now happens what you described there, a tick sound lasting the first few seconds the headphones are plugged in and if I try to play any media it happens that "instrumental effect", other heaphones do the same, so it's obviously the phone.I mean, is it really possible that some kind of problem occurred while trying to vibrate and play sound at the same time? Well it was for me, the phone was fine until then.Sorry for the boringly long post haha

  • 80G Headphone Jack not working

    My 80G iPod headphone jack stopped working.  I did the 5 R's.  Didn't fix it.  Transferred jack out of my old (dead) iPod to my 80G.  Nothing again.  Could have been a bad part though.  Can I buy this part on here?  Or is there anything else I can try?  Thanks a lot.

    Since you seem to know how to take them apart (and have the proper tools), maybe you can buy a broken iPod (of the same type) on eBay for the spare part.  Most iPods with a hard drive that are broken are broken because of a bad hard drive.  So your chances are good that the assembly with the headphone jack will be working.
    And you'll have some other spare parts, such as screen, click wheel, dock connector...
    If that broken iPod is broken because of a bad hard drive, but it is otherwise in better shape than your iPod, you can transplant your working hard drive into that iPod.

  • Mac Book Pro Headphone jack isnt working?

    Out of nowhere my headphone jack stopped working, i can only hear out of one ear. is there a way i can fix it or get it fixed for me?

    How old is your MacBook Pro, and do you have Applecare?  You might still be under warranty.
    Otherwise, have you tested your headphones out on another device and tried a different headset on your Mac?  Is the channel completely dead, or can you apply slight pressure to the plug to get the channels to work?
    Maybe answers to these questions will give clues to others here to help.

  • Satellite P745 Audio Jack / Headphone jack not working

    Good day to all,
    I have recently performed a fresh install of Windows 7 Ultimate on my Toshiba Satellite P745, and manually installed only important drivers (NVDIA and Intel Graphics, Realtek HD Audio Manager, etc.). I do not prefer the built-in restore factory settings of Toshiba, because I have tried using that before and it only degraded the performance of my laptop. I am using an external speaker instead of the built-in speakers of my laptop, because my harman/kardon is already broken, and after installing Windows 7, everything is working. 3 days after the installation, I cannot hear anything anymore from my external speaker. I tried reinstalling the Realtek HD Audio Manager (its version is 6.0.1.6305), but it still did not work. I tried as well to use other versions of the driver such as 6.01.7368, still it did not work. Lastly, I tried to perform system restore to the date when my speakers were still working, but it did not help at all.
    I was also able to verify that my external speaker is not broken, because I was able to use it on my personal desktop, and alternative OS for my laptop which is Ubuntu 14.04.
    I would greatly appreciate any help.
    I've read on some queries posted here that people are asking for the id of the driver for some reason.
    Here is mine:

    Hashtanksale,
    Not sure about Win 7 ,however, I had a similiar problem with Win 8.1. I wanted to upgrade from a Gateway netbook running XP. I bought a HP x2-k010nr running 8.1 from OfficeMax and it stopped working,died, after 8 hours. Well took it back and exchanged it for another HP x2-k010nr and it lasted two days. The software would listen to the external combo jack mic, however, mostly to the internal mic. Exchanged it for an Asus Transformer and it lasted two days and had the same problem.  Returned it and got a full refund. Seems there is a conflict between Microsoft and their vendors. If possible return your machine ASAP and wait for this issure to be resolved.

  • Headphone jack is broken but works when i forcibly push the earphones in

    okay so it seems like the headphone jack on my ipod classic 160gb (which is well out of warranty) is broken as it only works on one channel no matter what headphones i use, but when i push it in forcibly it still works in both ears for a second, but I can't hold it for long. I've tried cleaning any dust out with cotton buds and a can of compressed air but had no luck so far, should I persevere with this method or is there a chance the jack is still broken?
    cheers

    The jack is broken. You can buy and fit a new headphone jack/hold switch assembly. Getting the iPod opened up is a little tricky but there are video tutorials to help out. I've done several of these and also battery swap outs.

  • Redlight from headphone jack not work (Y410p)

    Hello hye  ,Sorry ,  Red light at my headphone jack gone when i format the laptop.
    and i want to ask.  That headphone jack had a driver for red light or not. because it look style when redlight at there..
    Sorry for my ENGLISH

    Welcome to the Lenovo Community !
    I am assuming that you did a One Key Recovery and restored your operating system to a like new condition ? 
    The red light should be OFF when everything is working properly on the your model.  If you did the One Key Recovery then the restoration corrected a driver problem with the audio that was causing the red light.
