Although the sbpro driver supports A-law encoding on AD1848 and compatible
devices, audiotool(1) does not and produces an error message if you select
A-law encoding. Use audioplay(1) to play A-law encoded audio files, or use
audioconvert(1) to convert the A-law sample into a format that audiotool
will accept, such as 16-bit linear. User-written applications can select A-law format
using the sbpro driver on AD1848 and compatible devices.
Compaq Deskpro XL Business Audio With Built-in AD184x Chip
Some system units have the headphone jack wired with its Left and Right
channels reversed, so you hear Left output in your right ear and vice versa. The
line-out jack at the back of the unit works as expected.
To find the active audio input jack on the back of your system, plug in a sound
source. Run audiocontrol(1) and select Record. On the Record panel, turn the
Record Volume and Monitor Volume sliders up so you can hear the output. Then
select Line In and, secondly, the Internal CD to find which audio input port
produces sound. If the Internal CD button does not appear on the audiocontrol
Record panel, use the Line In selection for the audio input. Use the Microphone
button to select the microphone jack on the keyboard.
The quality of sound is better when using an external microphone and speakers,
not the ones built into the keyboard.
