1 Troubleshooting Your PC

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.

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. If the power grounding of your audio components is inadequate, a humming noise may be generated. Plug

Occasional crackles when playing back sounds.

The PC hangs while recording.

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 system’s audio control software to change the audio interface’s 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.

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 µ-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.

If Your PC Has a Software Problem

Problem Solution

Refer to the application software documentation and/or the operating system documentation for guidance.

Recovering Hard Disk Contents

In the unlikely event of a hard disk drive crash, you can reinstall your PC’s preloaded operating system using the Windows NT4 and Service Pack CD-ROMs supplied with your PC.

NOTE Any software that has been installed on the PC after it was

manufactured, and any personal data that has been generated by applications installed on the PC, are not covered by the recovery process.

Changing the Hard Disk

If the hard disk is corrupted and you can no longer use it, you should replace it with a new hard disk drive. Refer to the Accessories Guide for information on installing hard disk drives.

If the replacement hard disk drive is brand new, you will need to partition and format the drive. Refer to your operating system documentation for information about how to do this.
