Sound loss

I was recently trying to pair a new bluetooth device with my desktop and experienced some difficulties.  I tried changing a few things and, in the process, have now lost all sound.  All of the devices claim to be working properly but nothing I do seems to get the sound back.  Sometimes I get a message that the "sound card" is not working now.  Any suggestions on how to fix it??

Hello @Geoff2,
I understand that after making some changes on your computer you no longer have sound. I would advise you to use the HP Support document: Using Microsoft System Restore (Windows 8) to simply restore your computer back to a point in time where the audio worked as is should and start over.
I hope this helps. Thank you for posting on the HP Forums. Have a great day!

  • Ipod to stereo sound loss

    I've been searching a bit for this, but has anyone noticed some serious sound loss when connecting ipod to stereo or television and trying to play music? I've used it for TV and I didn't notice any major loss, but for music (using the standard headphone jack to white and red plug), it *****! If I turn the stereo up full ball it still lacks any punch (on a cd it would deafen me at this level). I want to buy a car stereo with an aux imput, but don't want to if it's not going to be loud. The ipod is new, so just want to know if this is normal?

    I have used all of my 4 iPods as the main source for music connected to my living room stereo for years throug a docking station. (Not through the headphone output.)For my stereo i think the "latin" equalizer setting is closest to CD sound, but that varies. The sound is very close to CD sound and I do not lack any punch. I am using the same set up in the car and no problems there either. With the latest docing station the volume on the iPod has to be on full, but it automatically goes to full volume when docking.
    By the way, I am using it with to stereos, One Denon and one Bose.

  • Intermittent Sound Loss (SFX & Audio)

    Hi gang, I have an odd problem with intermittent sound loss (button SFX + audio) on my brand new ATV2 (HDMI to HDMI on a 2 year old Phillips 42"). The picture is great, but the audio only works about 50% of the time. (?!) I'm totally stumped. I did some troubleshooting. Restart, Reset, Restore. No dice. I swapped the cable and tried different HDMI ports — to no avail. I also spent an hour on the phone with an Apple tech. We did everything again and we turned off Dolby, etc. No dice. He suggested I bring the device into the Apple store, and they swapped it out for me. But I'm having the same problem with the new device — and AGAIN only 50% of the time. It seems totally arbitrary. Very frustrating. Any ideas would be appreciated.

    Did you try restarting your TV, the problem may be there.
    (I have a tv that starts to drop audio occasionally, although a restart of the tv will resolve the matter it does return perhaps weeks/months later)

  • Apple gives response on sound loss in iMovie '11

    I phoned up Apple 'Care' about the reported sound loss/sound syncing when exporting clips.
    Apple are not aware of any problems with the sound on the latest iMovie update. He suggested I look at my settings, and "Search on Google".
    Great help.

  • Sound loss when moving Final Cut Pro X project to Quicktime.

    This is a 33 minute football highlight film with music, live sound, radio calls, title screens and transitions.  The video is HD and transfers flawlessly, but the sound stops after 90 secomds amd never returns.  Not sure what I am doing wrong.  Have made 35 player highlight videos without an issue, but they are about 10-12 minutes long each.  So, I cut the video to 20 minites to trial a shorter version, and the sound cuts out at the same spot.
    The video pkays back perfectly in Final Cut Pro X.  Sent it to compressor directly, and aftr 17 hours, I got a "fail" message.
    Can someone help me?  This video is scheduled to be shown at a banquet on Friday night, and I can't show it if I can't get it to a bluray disc
    Thanks

    Last week I lost my audio shortly into the video.
    It disappeared around the point of the first transition.
    After deleting that transition and re-exporting the audio survived to what had been the second transition and so on.
    After deleting all the transitions the audio was perfect.
    I then put back the transitions and magically the video exported with no audio loss.
    At the time someone else seemed to have the same problem so it may be some bug or glitch.
    My solution was to delete all transitions and replace.

  • Crashes, sound loss, and other problems

    Hello,
    I have been having some serious problems over the past several months. In the past it was fairly manageable, but recently things have been getting worse.
    I have a 12-inch PowerBook G4, I bought it at the McGill bookstore in October 2004. The first problem was the apparently random crashes that Mac OS X (v.10.4.8) would experience from time to time. It was fairly infrequent at first so it didn't bother me too much (and I thought it was just some sort of glitch). But it persisted and came to be expected.
    What would happen is that my screen would darken and center box would appear telling me, "You need to restart your computer. Hold down the Power button for several seconds or press the Restart button." (it would display this message in English, French, German, and Japanese for my convenience). After I restart the computer I get the message, "The computer was restarted after Mac OS X quit unexpectedly". At first it seemed to be linked to time; after a while it would just crash, sometimes after an hour or so, sometimes after as little as five minutes. (I fear as I write this that I will have to start over). More recently I've come to associate the crashes with movement of the computer; perhaps the battery (which is pretty much dead after so much use) is affecting the performance, I don't know.
    The next problem, which coincided with the crashes, was my clock being reset. I assumed this was directly associated with the spontaneous shutdown of the computer, yet though the crashes continued, the clock was not always reset (just about a third of the time). This was a pretty frustrating inconvenience given the frequency of the crashes at the beginning.
    The major problem that prompted me to take action was the lose of sound. One day, about a month ago now, my sound suddenly stopped working. At first I thought it was a hardware problem, but then I noticed the sound was still working with some things and just not others. For example, the sound increase/decrease indicator (the 'pop' sound when turning up or down the sound) stopped working, yet the startup sound still worked. I've found that Realplayer, MPlayer X 2, and Windows Media Player work fine but iTunes, VLC, and Quicktime don't. Most of the applications simply don't make sound but when I try to video in VLC I get the following error: "auhal: we cannot find our HAL component" or "auhal: audio-device var does not exist. device probe failed."
    Other minor errors I have come across include inability to detect the Airport card (remedied upon restarting the computer) and occasional seizing up of the keyboard (the letter keys, exclusively, were unresponsive for sometime before working again suddenly without need of restart).
    I've run diagnostic tools such as Disk Utility and the 'fsck' command in single-user mode, but nothing has been detected. It consistently comes up saying that everything is alright.
    I have backed-up all important files and programs (with the exception of my Firefox bookmarks, do you know how I can save those?) and am prepared to do whatever it takes to bring my computer back to working order. I need my computer for schoolwork and assignments so if I can fix it myself in anyway... I would prefer to avoid lengthly repairs if possible.
    Please let me know what my options are, and/or possible things I can do to repair these problems. This whole affair is, unsurprisingly, driving me crazy.
    One last thing, upon launching Microsoft Word, I get the following pop-up:
    Application Launch Failure
    The application "Word" could not be launched because of a shared library error: "3<Microsoft Word><Microsoft Word><MicrosoftLSLibZ>"
    I do not know whether this is linked to my other problems or not. This too, is something that has recently come up and is significantly affecting my work (I have had to switch to writing my essays on TextEdit).
    Any help is greatly appreciated.
    Thank you,
    Eric Oosenbrug
    PowerBook G4   Mac OS X (10.4.8)  

    try shutting down, remove the battery, carefully pull out AirPort card and reinstall it.
    maybe run hardware test included with CD kit

  • TV @nywhere Video OK, But sound loss after 40 sec (solved)

    I Have a Problem With my TV @nywhere Master
    The Video I OK at all time But after a 40 - 60 sec I am Loosing the sound,
    Is there someone that can help me!!!???

    I have come across many reports of this problem on the Internet, and all of them relate the solutions second and third hand. Has anybody seen an official knowledge base article from Microsoft or Symantec dealing with this issue? I have scanned both sites and no mention. Since this problem affects multiple TV Tuner cards, I would have expected, some official statement somewhere.
    I have heard various reports that this is a Microsoft Messenger problem, an Norton Antivirus problem, a Norton Antivirus 2003 problem, a Norton Antivirus 2003 without a certain patch apllied problem, a Windows XP / Messenger / Antivirus problem, and it all depends on who is pointing fingers at who.
    The explanation has been that whether Messenger is active or not, at some point Norton Antivirus starts messenger, and subsequently interprets the Tuner video stream as a virus, at the same time Messenger starts chewing all the CPU cycles, and audio takes a dive.
    So what does that mean. If I have a high speed processor, I can compensate for the cycles and not experience the symptoms. Or maybe because I'm using Norton Antivirus 2004, it's not an issue. Or maybe I have a certain mysterious patch applied.
    Would I be satisfied with either MS or Symantec suggesting turning off Messenger scanning, or turning off Messenger. No way! For those who use Messenger as a means of communication, that should not be considered a long term solution. At the same time, turning off Messenger virus scanning is not a reasonable long term solution. Rather than opening my PC to the risk of a virus, I might ditch the whole lot of them including the TV Tuner, if that was the case.
    There is a responsibility for MS and Symantec to give a reasonable explanation / analysis of the problem and offer a long term solution, whether that is a fix or upgrade, whatever, something that their customer can use as a frame of reference to decide whether or not they want to go that route or ditch the lot. Pressure should be maintained on them to provide an official response to this problem.
    I would start with Symantec. What? You can't tell the difference between a video data stream coming from a TV tuner and a virus. Give me a break. Your just too busy coming out with the next version of Norton Antivirus to fix your existing code. That's were the money is.
    As a hot fix, turning off Norton Antivirus Messenger scanning is certainly the fastest and from reports, many have eliminated their symptoms this way. Eliminating Messenger is another story. You can't get rid of the sucker, without sacrificing your first born.
    Again, does anyone have a link to first hand, from the horses mouth, information re this problem?

  • Sound loss with Xillisoft

    I have the 60GB iPod. Purchased the Xillisoft DVD to iPod Converter 4. I used all of the "preset" settings, only changes were "checked" the box for Audio/Video Synch. under Properties. The converter did a fine job but the iPod plays the video and after approximately one to two minutes the movie "freezes" temporarily and then all sound is lost. If I exit the movie and try to replay it, the sound returns only to do the same thing after a minute or two.
    Anybody have this problem, specifically with Xillisoft?
    I read in a post on this site that I have to de-mux? the video and audio(someone please explain).
    I thought that Xillisoft takes care of this? Please understand that I'm not completely up to speed with this whole thing, i.e. take it easy one me.
    Note: I have tried two seperate DVD's that do the same thing.

    Maybe you don't have the proper audio rate or video settings. There is a great tutorial over at iLounge that gives you the proper settings that have no problems with iPod. (they use a different software but it will work if you can change settings, just change the to the recommended)

  • Sound loss streaming to atv2 from Macbook Pro

    Hi all, im hoping someone can help.
    I have various movies on my macbook pro running OS X 10.6.8 of various sizes, it seems that anything under 1gig in size streams to my ATV2 fine, sound and picture, but anything over 1gig the picture streams fine but the sound just buzzes loudly.  I have BT infinity with the standard router and modem they give, streaming wirelessly from the macbook to the ATV2, the ATV is hooked up to the internet via ethernet.
    Has anyone come across this?  Im hoping its a quick fix and just some setting that needs changing.  Ive searched the net various times but they just seem to deal with trying to stream dolby sound or picture issues.
    Thanks in advance for any guidance!

  • Sporadic Sound Loss in 3.0

    This is something minor but I thought it was at least worth noting. I think it seems to happen when you copy and paste text, but the sound will all the sudden stop working. Last night I did a hard reset on my phone and that worked fine. Today it happened again and my texts were no longer making any sound alerts, then randomly about 10 minutes later, sound is working again? It's kind of odd to me. I understand this is the beta and part of the reason why people like myself are testing, but I thought I'd post it up and see if it was isolated to my phone or others might be having a similar issue. If so, maybe the moderators/devs might see this here and rectify. Thanks all, aside from that the new update is awesome. Couple lag issues but fairly stable for a beta.
    Mike

    This thought is assuming that you have your settings set to the following:
    From the RT menu:
    Unlimited RT
    Playback Frame Rate & Quality set to Dynamic
    Multiclip playback is checked
    From the View Menu:
    Show Multiclip Angles is checked.
    Viewer or Canvas:
    Playhead Sync set to Open
    When you start playing your timeline, the canvas will display the current active angle, while the viewer will show the multi-up display. By default, this loads only the video into the viewer. You can confirm this by looking at the tabs at the top of the viewer, you should only see 3: Video, Filters, and Motion. So if you click on the viewer to make it active, there will be no audio.
    If you really need to hear audio in the viewer, then double click the multiclip to load it into the viewer, but doing this will set playhead sync to Off.

  • G4 Cube total sound loss

    Hi Folks,
    I was sat quite happily working away, listening to BBC Radio 2's great Steve Wright in the Afternoon over the Internet via a Widget on my Cube, when all of a sudden, the sound just stopped, along with a 'disconnection'-type noise.
    Having had the situation many a time that the Internet connection had been lost, I went to the Widget to reconnect to the signal, only to see that the signal was still streaming into the Widget. At the time, I was clearing out some duplicates in iTunes (a job that seemingly is endless), and I then further noticed that System sounds were not coming through to the speakers either.
    Finally, I checked by playing from iTunes itself, and there's very definitely no sound coming from my Mac.
    The speakers are Harmann Kardon Soundsticks II, which are connected to a Griffin switch that takes the line input to the speakers and converts this to USB so that I can plug them into the Cube. They've got power, and have worked happily for around eighteen months. If I unplug the line cable from the Griffin switch, I get a sound from the speakers, so they're definitely okay.
    So far, I've repaired permissions, verified my hard drive, rebooted, logged out & in, checked System Preferences & Apple System Profiler, but still no sound emanates from my Mac.
    Can anyone help, please?

    Hi,
    Thanks for the response and for the article link.
    I can't mark this as answered or resolved, but the Soundsticks are pumping sound out as I type. I'm just not sure I could repeat the process, nor understand which bit did what exactly. Talk about some odd behaviours...
    Your suggestion is sound: isolate the Griffin iMic. I plugged in my earbuds - no sound.
    Then, I thought, get out the old Cube speakers: I unplugged the iMic & plugged in the old faithfuls. On my desktop came an OS warning script, of the type seen in OS installations (black square with white text in four languages, explaining the only thing this here CPU can do is switch off, thank you very much).
    After the restart, Cube speakers working: so the sound card etc are all good. Next, I hot swapped the Cube speakers for the Soundsticks - no output, no connection noises, no power hum.
    So I plugged the Soundsticks into my iPod via line - no sound. Then I plugged the Soundsticks into my PowerBook via line - no sound. So I tried the iMic with the PowerBook & the Soundsticks - no sound.
    Even though the Soundsticks power light was on, I checked its transformer for warmth, checked all connections, unplugged power & plugged back in (a la 'Have you tried turning it off and on again?'). I hot swapped the iMic one more time into the Cube, and noticed again no connection noises or power hum, but after unplugging and plugging the line input to the iMic a couple of times, noticed the return of the power whine & connection noise. As I hovered around the Cube USB port, I got similar connection noises...
    Unfortunately, the hot swap again caused a problem, and the Cube shut down. After reboot, I went through your instructions again for the cuda reset, as I'm sure this Mac is showing the right kinds of distress that reset solves. I haven't done it yet though - can't bring myself to crack the case straight away now that the Soundsticks are working again.

  • 5G iPod sound loss

    I have a 5G iPod, 60 GB. At least three times in the last week, I've gone to start the iPod from a normal pause (display off, not in hibernation), and although the iPod indicated play and the progress bar moved, no sound came out. On one occasion, it refused to play audio until I tried to play a video, then it had the symptom described above.
    Resetting the iPod brings it back to normal, but it seems like I shouldn't have to reset daily. Has anybody else seen? I think that this has all happened since I upgraded to the most recent firmware.

    Actually this is a sort of old problem. I guess Apple never fixed it.

  • ATV2 sound loss from HDMI, Optical or both!

    Hi, Sometimes (and this is the rustrating bit), but not always the sound from my ATV2 will die. I have it connected to the TV via HDMI and also to a surround sound system via an optical cable.
    I've played around with the audio setting in the ATV menu (16 bit, Auto, Dolby on/off/auto) etc and the same still happens. I have some movies I've watched a couple of times and the first time around they can play with DD 5:1 sound and the next time will be stereo only.
    I've tried various different cables and all end up with the same results, is this and ATV problem? It just gets very annoying when you get to 15 minutes from the end of a film and the surround sound dies, then fingers crossed it *might* work through the TV sound to finish the movie off.
    Thanks in advance.
