Audio (sound) problems
The e-pc hangs while recording
Have you checked that...
You are not filling up your hard disk with
uncompressed digital audio. For example, one
minute of stereo sound recorded at a
resolution of 44 kHz will occupy about 10.5
MB.
No output from 8 or 16 bit digitized sounds
Have you checked that...
You do not have an interrupt conflict or that
you have not selected the wrong DMA
channel
Audio input from microphone too low
Have you checked that...
The microphone specifications meet the
requirements of the 16-bit sound
components. The microphone should be a
600-ohm electret type.

How


• 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.
How


Use your operating system's audio control software
to change the audio interface's DMA channel or IRQ
setting

Check the documentation that came with your
microphone
