Question about HP Pavilion dv9000z Notebook

Sound card broken? No normal sound and a constant buzz...

Today when I tried to record music via my mic/line-in jack (which I've done many times before and never had any issues with) there was some short buzz and after less than a minute the laptop started to buzz without a stop. I tried rebooting and just in a few seconds the buzzing started once again. I did a great amount of troubleshooting, checked all the devices, drivers, updates, etc. Nothing worked. Then I came to realise that no matter how I set the volume I can't get any sounds from the external/built-in speakers nor from the earphones...Now, everything else seems to be working fine, except for the fact that the buzzing is still here and that I have no other sound whatsoever... I'm really confused and desperate.

    Thank you, that sounds like one solution but my main concern is not the lack of sound but the omnipresent annoying buzz. I'm not really sure how to disable the sound through BIOS... :S

Sounds like you tried everything possible. Based on what you have stated that you tried already I would agree with your diagnosis of a bad sound card.
If this was my Laptop I would be looking for a nice set of USB speakers and Microphone or a headset.
You can either keep the speakers turned down or you may be able to disable the onboard sound through a BIOS setting.

Or even better. Here is a USB sound card with speaker and microphone jacks. Pretty Cheap too.

    I have to admit that I am not familiar with the BIOS(sometimes called "set-up" on the start screen) on your computer, but if you can get into it and look around it will be listed as sound card or onboard sound chip, or something similar to that. Lacking that, you could get a headphone plug at radio shack and plug it into the headphone jack with nothing attached to it. This would rout the output(buzzing) to a non-existing set of headphones.

    I know it sounds like a "Mickey Mouse" fix, but it is surely the cheapest and quickest fix around.

My line 6 spider jam buzzes in all amp models. I tried a reset with no luck. Sound almost like a blown speaker but that is not the case. All recording play perfectly.


Sound like an open ground wire on the output jack. The buzzing is usually due to this ground problem. check all wiring to the output jack.

Audio recorder


the cause is using the mixer incorrectly, or mixer is junk, IDK,
now idea at all what system parts are there, not a clue here.
in the mixer, uncheck microphone.
Computers can be set up 1000s of ways, you know?
Not even a clue at all what PC< desktop or laptpo
no clue at all. just vague DJ bla bla....
answer is so will pure generic electronics (im certified tech. retired)
Most PCs of all kinds have sound card, or built in. (or just 1 chip)
be it a destop or lap top,
my PC has a sound card, (fancy,) DTop,
with 7 channels and all that stuff.with matching powerful software.

on a real desktop with a real sound card it has many jacks there
not just 2, (mic/speaker.,)
mine has line in, and line out. and many others for speakers,

there are 2 ways to record
1: using and external , say Mp3 recorder. (and 100 other ways )
2: and using the built in sound recorder in windows, do you have windows. you never said that nor which windows

the 1st choice is hardware, pure electronics, in fact tape recorders worked there for since first one made, using line in. to recorders.

choice 2, is software, you can buy a APP to do that, that is better than what Windoz offeres.


see here?
https://en.wikipedia.org/wiki/Sound_card

see that lime green wire?

the top sound cards all have special softeware
that has a super fancy MIXER, the mixer allows you to mix
anything you want. with a click of a button
if you dont have good sound card or matching software
all you get is windows basic crippleware. weak and very limited.
so next time tell the helper what you have.
fully and get 10x better answers.

here ill wet your whistle, on what can be done.
you want 2 CHANNEL STEREO recorders.
or even TOSLINK connections.?
How good is your source music, ? if poor then use cheap hard/software but don;t expect windows to do this well.
if running windows 10 go to the MS windows, STORE,
and buy a better audio software package.

ideas, are endless in recording
hardware super good. or better,

last is fancy app software like this.
I use this
it does it all. for near nutt'n.
GOLDWAVE (ive had it for 20 years too)

https://www.goldwave.com/


last
the word Disk Jock is a persons or is one of many hardware products, not stated by you.
is it this. old box? by maker NUMARK?

https://www.numark.com/images/product_downloads/dm925_referencemanuals_00.pdf

in the above jack 15 line out goes to sound card, LINE IN.
then in the PC you play or record off of LINE -in in the PC.
if you dont have a real PC with a Real sound card
this can be hard, using the MIC as a line input will cause
huge overload saturation of the mic amps, and sound like H3LL..

Behringer Xenyx 502 Mic buzzing...PLEASE HELP


Get yourself anti-static spray and spray over the connector before inserting into the jack, most times its dust or static buildup which causes that buzzing sound and in other times replace your mic

I'm no expert in sound cards but I know some stuff about music recording, when sound is distorted you can see the wave you recorded as a flat in both top and bottom parts of the wave, this happens when the inpu to mic or "mic volume level" is too high, try decreasing the volume level of your mic via recording software or use the small speaker icon in the lower right part of windows taskbar to get to the windows default sound card's properties, get to the mic lever and lower it at will to get the desired volume level you need.

See if this solves your problem, if not don't hesitate to reply with some more info to see if I can help.

I record a podcast with the 8track multimix usb Alesis. I use one XLR - Jack input and the rest XLR-XLR. There are 4 inputs being used in total. I seem to be getting alot of hiss and buzzing from the...


What is the source of the input signals? These need to be balanced lines and the sources need to be balanced. If you happen to be using condenser mics, you probably haven't turned on the Phantom Power in the mixer. If you are recording from a sound card in the PC, those have a lot of noise and are unbalanced and you have to use DI's with ground lift ahead of this mixer.

Sound card won't work with external input


Are you trying to record and listen at the same time? It doesn't usually work that way, the computer has to process and encode the audio signals before they can be listened to. Once you restore the computer, are you able to listen to the recording? If you have onboard sound, rather than a separate sound card, all the audio processing is done by your CPU. If you are trying to listen to the audio as it is being recorded, you are probably overloading the capabilities of the device and its shutting itself down. Try to record without listening. Also make sure you have the latest drivers. If it is onboard audio, check the manufacturer's website for updates. If you know that it is Realtek AC 97 (probably says so your manual), you can download new drivers from the Realtek website.
