soundcard problem

This is a query about a good brand soundcard.

It distorts any externally input recording, whether from radio, deck etc.

It sounds like satan is speaking to me.

However, the audio output is ok if the mp3, wav etc file is played.

If the "distortion" is not noise but actually changing the speed(assuming satan = slowing down) then either you are not recording it correctly(although strange it is possible) or there is something wrong with the card. The hardware isn't going to slow it down but a mismatch in recording frequencies at some point in the chain will. Either the clocks on the card are bad or something else. I'd imagine the same clocks to output are used as inputs so it probably isn't that.

I would seriously look at your software recording method as that seems the most likely culprit. If all else fails, send it back.

If your serious about getting help though then you might upload a sample. Would be very simple to find out if it's some issue with the sample rate being changed.

For example, to "sound like satan" all you have to do is play back the sound file at, say 1/10 it's rate(which is normally 44100). This is analogous to slowing down a record player. The files have the rate stored inside and, for some reason, it could be set wrong or interpreted wrong.

We need more info to determine the specific problem though. What software are you using and did you change any of the record settings? Do you have another computer to try it in?

That's because you have a miss match, and most likely over driving the input. Try turning off the Mic Boost in the mixer settings for starters. Use a matching network in the input..

Jamie is pointing out the most likely problem - are you feeding line level into the microphone input?

I have tried virtually everything =85 switch off the Cd, Mike, Midi etc, while leaving Line in on.

Several different softwares also sound like Satan=92s voice, like listening to a booming, crackling sound in a tunnel/thunderstorm.

If you say leaving the LINE on, this leads me to believe that you have a mid range or upper end sound unit. Most onboard, low end units only have a Mic input, which can be used as a line input if the unit supports it. Some are fixed mono inputs (1 channel) while others are stereo but combine left and right together for mic operation. This normally happens at the hardware end of it, the jack. Also, these units in many cases have a small power source to power up amplified mic's which in many cases, interferes with little devices like Ipods and such, because the outputs are not DC decoupled.

On another note: Line input normally requires 600mv on average, input. Most devices designed for low impedance connections, like speakers for example, do not generate this level of signal and there for, may distort when attempting to. In this case, a matching transformer would most likely fix a few of your issues..

Your final resolve could be a smoked pre'amp that you most likely caused.

oh, you might have some effect turned on.

Soundblaster has something called EAX that you can set up different environments. It maybe something like that going on. If it's noise it will sound very distorted like when a TV is not on a station. If it's some type of "effect" like thing that seems to be going on(it might be noise with it if it's turned up too loud and causing clipping) then it's probably some setting in the software.

If you are recording to Line In (not Mic In), then presumably you have an external preamp (if using a mic) or some other external program source that should have its own volume control. Try turning that *way* down and see what happens. If you were overdriving the input stage, that should make a big difference.

Others have noted that you may have some "effects" enabled. Controls for these can be hard to track down, since they often don't show up with the normal Windows-provided volume controls... you may need to open a special app provided by the card maker. (Usually via an icon in the system tray.)

Vista/Win7 makes it even harder. You may have to right-click on the default list of available devices/controls and tell Windows to show you the rest of them.

I showed it to the service center, who say that the card is fine, but has outdated technology.

Here is the Yamaha soundcard collaborating with crap hardware companies to peddle their junk to millions of us Indians.

Sorry, I don't but the "outdated technology" answer. Any Windows sound card with a proper driver should not produce distorted sound, if you are using it properly... even the very cheapest.

Your description of the problem "like listening to a booming, crackling sound in a tunnel/thunderstorm" could indicate several different things. "Crackling" might mean you are overdriving it. "Booming" might mean you have some bass effect on. "Tunnel" might mean you have reverb on. It also might mean that you are trying to record through a microphone that is getting feedback from the speakers. (If so, use headphones to monitor.)

Did you look around for a custom Yamaha control panel and see if there are special effects active?

Did you try cutting the input levels *way* down at the source, as well as the sound card mixer? Are you sure you haven't activated "what you hear" or "stereo mix" which is producing internal feedback?
