#
:recordctl-AutoAdjustButton
The Auto-Adjust feature attempts to set the audio
record volume level to a value that ensures a
sufficient signal strength without audio
distortion.

Press the Auto-Adjust button to begin automatic
adjustment of the record volume level.  Speak
clearly into your microphone using your normal
speaking voice (try reading this text message, if
that helps).

The record volume adjustment will continue until a
reasonable input level has been maintained for 5
seconds.  Be sure to continue speaking until the
adaptation is complete.

If you have directly connected an audio source
(such as a CD player) to the input port, be sure
to play a loud section while the Auto-Adjust
operation is in progress.  Adjust the Monitor
Volume slider to be able to hear a directly
connected audio source before and during the
Auto-Adjust.

The Record Volume slider may be adjusted manually
at any time during the Auto-Adjust operation.
#

Be careful not to turn the monitor volume up too
quickly if your input source is a microphone, as
this may cause feedback.

#
:status-Popen_flag
Play Status `Open' is set whenever a process has
opened the audio device with write access.  Since
the audio driver enforces exclusive use of the
device, processes that want to perform audio
output must wait until the audio device is closed
before they can gain access to the device.

If a process cannot open the audio device for
writing, the Play Status `Open' flag can help
identify some other process that is holding the
device open.
#
:status-Ppaused_flag
Play Status `Paused' indicates that output to the
audio device is temporarily suspended.
#
:status-Pactive_flag

#
:status-Ropen_flag
Record Status `Open' is set whenever a process has
opened the audio device with read access.  Since
the audio driver enforces exclusive use of the
device, processes that want to record audio input
must wait until the audio device is closed before
they can gain access to the device.

If a process cannot open the audio device for
reading, the Record Status `Open' flag can help
identify some other process that is holding the
