PC Has an Audio (Sound) Problem
Problem To try and fix this...
No sound when running
any applications. 1 Check that the speakers and headphones are connected correctly.
2 Check that the integrated audio interface is enabled in the Advanced
➪
Integrated Audio Interface menu of your PC’s Setup program.
3 Check that the audio driver has been installed (under some operating systems, a
speaker icon will appear in the bottom right-hand corner of your screen if the driver
is installed).
4 Double-click on the speaker icon to check that the volume level is set high enough
to be heard and that Mute is not selected.
5 Check there are no hardware conflicts with other devices. If there is a hardware
conflict, you will need to allocate resources through the BIOS. To do this, ensure
that the
PnP Operating System field is set to NO , and reserve an available IRQ
for the other device in the Advanced
➪
ISA Resource Exclusion menu of your
PC’s Setup program.
Audio input from the
microphone is too low, or
no audio at all. 1 Check that the microphone specifications meet the requirements of the 16-bit
sound components. The microphone should be a 600-ohm electret type.
2 Double-click on the speaker icon to check that Microphone is selected, and that
the volume level is set high enough to be heard. Ensure that the Microphone Boost
option is selected in Multimedia in the PC’s Control Panel . To open the Multimedia
Control Panel, go to Settings
ð
Control Panel in the Start menu.
The PC hangs while
recording. 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 m-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.
DOS legacy game does
not work. PCI Audio is not SoundBlaster compatible. To use DOS games, you will need to install
an ISA accessory board.
