1 Troubleshooting Your PC If Your PC Has an Audio (Sound) Problem
If Your PC Has an Audio (Sound) Problem

Problem Solution

WARNING: If your PC is a multimedia PC or if you add a sound card to your PC, always turn the volume down before connecting headphones or speakers, to avoid discomfort from unexpected noise or static. Listening to loud sounds for prolonged periods of time may permanently damage your hearing. Before putting on headphones, place them around your neck and turn the volume down. When you put on the headphones, slowly increase the volume until you find a comfortable listening level. When you can hear comfortably and clearly, without distortion, leave the volume control in that position. No sound when running any applications. If you are using Windows NT 4.0, check the volume, mute, and balance settings. Refer to the operating system documentation for more information. Absence of sound can also be caused by a hardware conflict. Hardware conflicts occur when two or more peripheral devices compete for the same signal lines or channels. Conflicts between your audio interface and another peripheral device might be due to the settings of the I/O addresses, IRQ channel, or DMA channel. To resolve the conflict, change the settings either of the audio interface or of any other ISA accessory in your system (refer to page 21). This might be due to the DMA channel selected or to an interrupt conflict. Use your operating systems audio control software to change the audio interfaces DMA channel or IRQ setting (refer to page 21). Check that the microphone specifications meet the requirements of the 16-bit sound components. The microphone should be a 600-ohm electret type.

No output from the 8-bit or 16-bit digitized sounds. Audio input from the microphone is too low, or no audio at all. Humming noise. Occasional crackles when playing back sounds. The PC hangs while recording.
If the power grounding of your audio components is inadequate, a humming noise may be generated. Plug all devices into adjacent power outlets (outlets within 5 cm / 2 inches of each other), or use line filters. These crackles are usually the result of your PC being unable to transfer audio samples within the required time. A solution is to use a lower sampling rate. Recording and playing back at 22 kHz is less demanding upon system resources than recording audio at 44 kHz. Uncompressed digital audio can eventually fill your hard disk. For example, one minute of stereo sound recorded at a resolution of 44 kHz will occupy about 10.5 MB. Before recording, check that there is enough free space on your hard disk. Data compression can reduce the space required. The A-law and -law hardware compression used by the audio interface enables the sampling of sound at a resolution of 16-bits, but it generates the same quantity of data as an 8-bit sample.
