Sound Distortion Problem
The sound on my son's Acer Aspire One Netbook D250-1165 is distorted. It sounds as if you're standing outside a cave listening to someone yelling from far inside the cave (best way I can think to describe it). I've searched for something that I could download from the internet (preferably free), but none of the things I've tried have been successful. Any suggestions?

Distortion can occur at almost any point in the audio pathway, from the microphone to the speaker. The first priority is to find out exactly where the problem is.
Ideally, you would want to measure the signal level at as many points as possible, using a VU (Volume Unit) meter or similar device. Generally speaking, you should keep the level below about 0dBu at every point in the pathway.

If you can't measure the signal level, you'll have to do some deducing. Follow the entire audio pathway, beginning at the source (the source could be a microphone, tape deck, musical instrument, etc). Here are some things to look for:
- Is the distortion coming from a microphone? This could be caused by a very loud noise being too close to the mic. Try moving the mic further away from the noise source.
- Are you seeing any "peak" or "clip" lights on any of your equipment? These are warnings that a signal level is too high.
- Are any volume or gain controls in your system turned up suspiciously high? Are there any obvious points where you could drop the level?
- Are your speakers being driven too hard? If you have an amplifier which is pushing the speakers beyond their design limits, then be careful - you may well find that the distortion becomes permanent.
- If the distortion is coming from occasional peaking, consider adding a compressor.
- Could the distortion be caused by faultyequipment?
- Is the problem really distortion? There are some other unpleasant noises which could be confused with distortion; for example, the graunching sounds made by a dodgy cable connection or dirty volume knob.
