Incompatible Audio volume T420 - Audio problem.

Hi all

recently I've been an audio problem with my T420. It doesn't matter if I use the built-in speakers or an external playback via the audio device, audio volume goes up and down several times for a minute.

It's rather annoying and irritating. I use the standard driver provided by Lenovo and with stock settings.

If someone had this problem and could give me some advice?

Thank you very much!

The framework was already to the people with reduced mobility.

I thought, maybe that's the problem, I've been experience, because it is only when I used Ethernet instead of WiFi: DPC latency + audio / mouse skip and stutter on t420--Lenovo's community

I tried the proposed parameters, without success.

Interestingly, re - install the same drivers that have been installed previously seems to have solved the problem.

Maybe some settings or installation screwed up.

    Hi, I have audio problems! I downloaded Skype on my windows laptop 10, and I have audio problems with only my Skype. I checked the audio setting on my laptop and they are very well, I tried to save regularly, and it was perfectly good. I checked the audio on my Skype, they seem to be well, but does not record the microphone. When I talk about the green line of volume is not hear me, and move. However I tried to snap my fingers just above the mic, and if I did it really hard two or three times the volume of the green line would move just really slowly, however when I spoke into the microphone it is not. I deleted and downloaded again, but has not fixed the problem and I don't know what to do. None of the parameters have changed, but when I checked my setting of the laptop, Skype was not one of the apps listed as the microphone (and I don't know how to change.) In fact, when I checked all my settings of the computer, Skype did not appear for the use of microphone, speakers or camera (but I get only problems with the audio.) Please get back to me as soon as possible to help with suggestions! I use Skype to talk to family and work, but also to stay in touch with teachers and take classes.

  • HP Probook 430 G2: Audio problem

    I got my new laptop (HP Probook 430 G2) barely 4 days ago and I already had a problem with it.

    I find this question every time, when I try to listen to music etc., headphones or 5.1 speakers (both using 3.5 mm jack).

    When I use Google Chrome or Windows MediaPlayer etc. If I stop to listen for 5 minutes (stop the video), then the audio "dumb"(barre de son dit qu'il n'y a son sort) but nothng can be heard. "." I solved this problem simply by setting the volume level 0 and back where it was in the first place.

    This problem came a bit annoying on a long term, so I hope someone can help me with this problem

  • 8 slate Pro audio problem: headphone output

    Hello

    I bought my slate 8 Pro (model 7600US) to replace my Blackberry playbook. It is the great Tablet (screen perfect last Tegra 4 CPU, battery in good condition, good speakers integrated), but after the use of the Tablet for several days, I am surprised by problems with audio quality of the headphone output. I use mainly compressed with headphones (audio books, Netflix, music, etc.), so when I connected my Ultimate Ears Super.Fi 5 Pro (headphones ultra-sensitive 119db/mW, 12 Ohm), I got very sensitive background noise, artifacts and, what is very annoying - variable pitch tones when changing tone based on the activity of the Wi - fi and load CPU, especially on low volume levels.

    So I tried using headphones from Shure (109db, 29 ohms), less sensitive 4ca as KOSS KTXPRO (106db, 60 ohms) with the same results. HP Slate 8 Pro is not powerful enough to Sennheizer 555 (105db, 120 ohms) but I also had the artifacts and noise of not. Finally I tried junk headset $2 and found the sound sounds and tones perfectly acceptable ground level, but the sound quality with these phones is terrible.

    To compare, I tried all my headphones with Nexus 7, Samsung Note 3, IPhone 5 and Playbook without problem.

    I have returned the shelf at the store and replaced it for the new, but I had similar problem.

    Please let know us, what I have to try the third time and replace the Tablet, or it's problem of hardware design, which cannot be resolved. Is it possible, that developers of HP can fix it in software configuration in a future update?

    I understand, this tablet is not an audiophile device, but when the HP Web site indicates to this tablet: "Tuned by Dr. Dre himself, Beats Audio™ allows you to hear the music the way the artist intended.", it must at least provide acceptable audio quality for most listeners. I love HP Tablet a little, but if audio problem cannot be solved, I have to look for another option like Samsung or LG.

    Updated my slate 8 Pro to KitKat 4.4.2 and looks, that his problem slipped.  With this update, noise and less noticeable artifacts, sound quality is acceptable now, even for sensitive headphones.

    Try to change volume settings and see if that fixes the problem.

    1. double-click on the icon of volume control main windows in the taskbar

    2 options-> properties > look for the choice of the mixer device.

    3. Select your tuner > check all boxes

    4 ok

  • Low audio problem Windows 7

    Hello

    This is my first time to a post here, so I'll get to the point.

    So, recently, I just had a virus on my laptop, everything is resolved except my audio problem.

    I had to go into "Safe Mode" while the virus was LURKING in my laptop, I had deleted some unwanted files

    It comes from the virus.

    ACCIDENTALLY, I deleted half of what was in my "common files" folder witch was located in:

    C:\Program Files\Common Files

    I have still a few other folders inside this folder... I used to have a lot, and I think that some of them were important.

    Only after that when I rebooted my computer, I realized that my audio seemed low. (My volume was 16% and it is always

    the volume loud enough and perfect for me).

    Also, YES, I tried the troubleshooting method everyone does, and it is always at low volume.

    It does not solve the problem. The same day, I caught the virus, it was withdrawn after a few hours, so all is well.

    Well, there you go, that's my problem. Please any help would be appreciated!

    Hello

    Thanks for the reply.

    In this case, I would say that you want to run system restore to recover all the files. After that, if you have any problem of virus.

    Let us know we will certainly help you.

    Refer to:

    http://Windows.Microsoft.com/en-in/Windows/system-restore-FAQ#1TC=Windows-7

    Note:

    When you use system restore to restore the computer to a previous state, the programs and updates that you have installed after this date are deleted.

    I hope this helps.

    Kind regards

  • audio problems - no device not connected

    original title: audio problems

    The audio on my laptop stop working. I tried to do troubleshooting, still no results. When I try to adjust the volume, it says no audio device connected, but there are built-in speakers. What can I do to fix this?

    Which laptop brand and model and what version of Windows?

    You could try visiting support site for this specific model of laptop on the manufacturer's website and download the latest audio driversavailable, and then install them. Who can decipher Windows problem with audio and make it work again.

    Also, wouldn't hurt to search for malware with a tool such as Microsoft Security Essentials , Malwarebytes , or SpyBot in case some malware is active on your system and interfere with it in a way that has disabled the audio.

  • Ever since I started to update to 34.0.5 I have known many audio problems.

    Since Firefox updated to 34.0.5, I have known many video and audio problems. At first, I couldn't play the videos at all, but install Shockwave Flash, which sets. All my videos play in silence. I've updated my plugins (Quicktime and VLC were the only ones to ask for an update) should not have solved the problem because I do not believe that I was actually using these plugins at the time, but nevertheless, it seems to have worked. Now I can play videos with sound, but the quality of this noise is severely reduced and even sometimes staticky. What gives?

    These are the same products - 'adobe flash player' is the consumer in the face of term "shockwave flash" the technical name...

  • Pavilion 500 215 el: audio problem Windows 10 anniversary update

    I have an audio problem, then before moving to Windows 10 or the update of the anniversary of the audio working properly after the update I noticed immediately that the sound is distorted or "crunches".
    I haven't identified the problem because it's random, very often and it's very annoying, my sound system is its IDT DTS + I tried to reinstall the drivers with the latest version but some of the problem persists...
    Only, I noticed that the problem is more 'feel' when the bass setting is higher or when I change the audio setting to my taste.
    I ask you to help also became very boring because without my custom settings is really horrible!
    Thank you.
    Sorry for the English, but this isn't my mother tongue, I used google translator.

    Hi there @Alexcpp,

    Welcome to the Forums of HP Support!  I understand that, after the update of Windows 10 anniversary, you had some sound problems.  I'm happy to give you a helping hand with this.

    Check the support page for your model of HP Pavilion 500-215el desktop PC, there don't seem to be updated drivers, and you have already tried to reinstall existing ones.

    You can always try to use the HP Support Assistant, HP PCs - using HP Support Assistant (Windows 10, 8, 7) to see if there is a driver available that is not displayed on the support page. It is unlikely, but there is always a chance that the page has not yet updated.

    Another possibility is to make some adjustments on your system, just in case there is another driver or software that interferes with the audio, which could cause problems of lag. You can try the search, even if these: computers HP - computer is slow (10 Windows), HP - slow Internet troubleshooting (10, 8 Windows) computers.  They are never a waste of time because often there is something that could help the overall performance of the system.

    Please let me know if it works for you and if it does not solve your problem, please mark this message as a solution. Bravo would be appreciated as well.
