Have you checked the Line-In *recording* level on your soundcard? That would be my first guess if the sound is being brought in through the soundcard...

Invest in a seperate sound card rather than using onboard audio.

[JtFan]

i dont really understand what do you mean do u have any settings that you recommend

[housepig]

what application are you using for capture? some of them don't play well with an onboard sound card...

[pbemer]

I think it's your sound hardware. You may have better luck with a sound card that isn't integrated, but even though you may get a good quality sound out of it, if your software can match the sound to the vid, you'll still have problems. What software are you using to edit your capture?

i use avi-io and i tried win dvr

I had essentially the same problems with my ATI AIW and the same AC'97 onboard sound (audio was distorted, too loud in spots, too soft in others...). I tried all the "make sure the line-in is selected" and adjusting the recording level as far down as it would go, but, to no avail. I finally invested in a new PCI sound card, and that has solved the problem. Probably even a reasonably priced sound card will help-no need for a SoundBlaster or anything like that...I bought a cheapo sound card off Ebay, then disabled the onboard sound.

I've been having the same problem. I have an ATI All-In-Wonder Radeon 7500, running Windows XP and am using a SoundBlaster PCI sound card. I also have onboard sound (which is disabled). I tried using it instead, but the problem still appears. Also had the same problem with my old All-In-Wonder 128.

The only thing that works for me is to have the levels down fairly low, then when I re-encode my videos in TMPGEnc, I boost the audio (depending on the level I have to use to get clean audio levels, anything from 200-400% ampliflication)

What should I disable?

[Craig Tucker]

Once you have got a pci sound card installed dissable the onboard sound in the bios.

Going to sound werd but some sound circurity are a bit thin on supply voltage filtering. So if you have a cheep PS feeding a MB or even with a lot of stuff drinking power can cause problems. IE buy a good PS or a good sound card. Both should solve the problem.

Running in a revamped video computer one of Fry's combo CPU and MB that are listed for problems but feeding a good quality PS to it the sound is super quite. The PS you get in a cheep 29 to 49 dollar case are usally not that good.

Hi all,

I have more or less the same problem,

I have an onboard AC97 soundcard that I've kept disabled all the time, in order to use my PCI Soundblaster Live Platinum;

Anyway, I can't imagine why, captured sound is TOO LOW volume, so, as a test, I decided to try with the onboard card - although I am aware that onboard cards aren't generally as good as PCI ones, but I just want to make a test;

So, I :

1) Entered BIOS and enabled the AC97 sound card driver - OK

2) Entered Control Panel and, under audio devices, as expected, on the drop down menu, I have two options, so I choose the NVIDIA one for both playback and recording;

3) ummuted all devices and selected line-in for recording - OK

But...THERE'S NO SOUND AT ALL !!

When I turn on the Computer, I can listen to a metalic voice saying something, incomprehensible;

When I make the NVIDIA test, it identifies my voice going to the microphone, the sliders get movement, but there's no sound on speakers;

When I load the NVIDIA control aplication, the sliders have movement, it shows the stereo sound that is playing on CD through Windows media player but, again, theres no sound on speakers;

I haven't made any hardware change except of course from changing the line-in-out cables from the PCI card to the onboard one;

ANY GUESS ??

Also, any ideas on why the sound from the (supposed to be better quality) PCI card is so LOW volume ?? How to fix it ???

Thanks,

Andre

Different card have different input circurity. Can be due to input Impedance and gain of the first amp. Some card to keep now level acceptable will have low input and use the audio amp chain to do the boost so to speak. Kind of like Dolby B for cassette tapes. Cheep trick but works.

Have you tried a constant sound source? One that just emits a constant 1khz tone? Some of the early test Audio cd had special whight noize/tone tracks.

Also do you have correct drivers? Nvidia can be a small problem some times in their sound department.

Hi Nightwing and friends,

There's a "test tone" at Nvidia software, and even so there's no sound on the speakers

Curiously, I am sure the card itself "recognizes" the CD, as the sliders at NVIDIA sw moves, but there's no sound to the speakers.
I have NVIDIA correct drivers;

If it's soundblaster, then check your mixer setting for the record volume.

One other consideration. While you would think that "Line In" is your best choice, I found that on my AIW Radeon I got much better results by choosing the "Stereo Mix" option.

FWIW,

Thanks Ewan, I think I've cleared my problem, but have found another one

Actually, I had BOTH video card - audio card connections done, two cables, both internal and external, and that was the reason for the low volume sound.

I unplugged the internal one and now I have a TOO loud volume - things have gone the opposite way.....I'll try your tip;
