If
the test program stops or displays an error message when it is checking
the Audio interface's base 1/0 address, interrupt, and DMA channel, it may
be due to a conflict between the audio card and another peripheral card.
To resolve the conflict, you have to change the settings
of
your audio card.
(See Appendix
Bon
how to change the settings and resolve the conflicts.)
If there
is
no sound output during the test, check the following:
D Speakers are connected to the
card's
audio output connector.
D Volume control knob
is
set at mid-range.
D No hardware conflicts between the audio card and another
peripheral card.
The built-in stereo power amplifier has a maximum output power
of
four watts per channel for four ohm speakers and two watts per
channel for eight ohm speakers. Do not play at maximum
if
your
speakers cannot handle this power.
