1. If you are using digital speakers that have a stereo
jack and you want the system to autoswitch to
digital, use a stereo-to-mono adapter to engage the
auto sense feature, or use multimedia device
properties to switch the audio signal from analog to
digital.
2. If the headphones have a mono jack, use the
multimedia device properties to switch the system to
analog out.
NOTE: If you set digital as the Output Mode, the
internal speaker and external analog speakers no
longer output audio until you switch back to an auto
sense or analog mode.
If you set analog as the Output Mode, external
digital speakers do not function until you change the
output mode back to an auto-sense or digital mode.
Shut down all open processor-intensive applications.
1. Before recording, be sure there is enough free
space on the hard drive.
2. Try recording the audio file in a compressed format.
