Hp pavilion running vista. Can't turn on stereo mix to record the sound the computer is making

I dont know exact model of your dv2000 hp laptop is, there is many versions of them (as an example HP Pavilion dv2401tu).

Microphone drivers are part of the sound driver package. Suggest if you are running 7, go for the vista drivers. 7 32bit, vista 32bit drivers. 7 64bit, vista 64bit drivers.

Windows update is another option for finding sound drivers for the microphone.

Yes sound card plus audio driver is needed for microphone to work.

Here is the audio driver link

Download it and have it install.

here is the details of what to plug in your sound card

line output (usually with a 1/8" stereo minijack). You can feed this into a cassette deck or an amplifier (ideally connected to a good pair of near-field monitor speakers) for playback and mixing purposes. If you have a really cheap soundcard, it won't even have this and you'll have to get your output from the...
headphone jack (with a 1/8" stereo minijack). You can use this for monitoring while recording, but don't use headphones for mixing.
line input (usually with a 1/8" stereo minijack). This is the only thing you should plug any of your musical recording stuff into.

Sound and Recording jacks stop working on the DV6000 series due to the ribbon cable running under the power button. when the power button is pushed it bends the flex cable and over time it breaks the connection rendering the front jacks useless you can buy a new upper button panel for about 20 dollars on ebay

Simply re-install the software and all your original data will be restored. If you purchased a downloaded version, go to the site from which your purchased it and request your keycode again, and permission to re-download. Then burn the text file with the keycode and the downloaded installer onto a CD so you won't lose it again. Another solution is to get Nero.

What exactly is your problem?
Please explain a little better what you are needing.

I've upgraded the driver from HP sp34200 version 3.26.0.0 to 3.45.0.50 using the files from Microsoft update catalog. This driver is now 3.45.0.50 and includes STEREO MIX. You can use the setup.exe for automatic install.
Note that due to changes, the driver is obviously no longer digitally signed.
The driver matches: HDAUDIO\FUNC_01&VEN_14F1&DEV_5045&SUBSYS_103C30D9
