Information that I received from Behringer. If you toggle the red 2-tr/usb buttons, then it will fix the issue.
Connect the USB connection from the mixer to your computer.
You will need to select the 2TR/USB to CTRL ROOM button so that the computer output will be routed away from the main mix to the CTRL ROOM output. Do not press the 2TR/USB to MAIN button. You will want to connect the control room outputs to your power amp or powered speakers and control your monitoring level via the CTRL ROOM knob. You will be able to monitor through the speakers or the headphones.
The USB interface built into the mixer is class compliant under Windows and uses core audio driver on a Mac. This means that it doesn't need a driver to be installed when used with Windows XP or Mac OS X. The interface built into the mixer uses the generic Microsoft USB driver, which is built in to Windows XP. The interface built into the mixer doesn't have to have a driver of it's own at all.
XP
From the Start menu in Windows XP, go to control panel > sounds & audio devices > select audio. Set your default sound playback to USB Audio Codec. Also set the default recording to USB Audio Codec.
Vista
From the Start menu in Windows Vista, go to control panel > sounds. Set your playback to USB Audio Codec. Also set the recording to USB Audio Codec.
In addition you will need to select what interface is assigned in your recording software. There should be some kind of preferences menu or options menu to select it. Refer to the users manual of your recording software for more information.
You can download Audacity from the BEHRINGER website.
http://www.behringer.com/EN/Support/..Downloads.aspx
Alternately, you can get Audacity directly from Sound Force. http://audacity.sourceforge.net/
Go into the edit > preferences menu of Audacity. In the Audio I/O menu, here you can select the playback device and recording device. This is where you select the USB interface. In the recording section, you will want to have the channels selection set to 2(stereo)<<<<<<<<<<
Make sure to have both boxes checked.
-Play other tracks while recording new ones.
-Software play through (play new track while recording it)

Remember any of the input channels routed to the main mix, should also be sent to the USB output as well. If you have a microphone connected to channel 1, make sure the MAIN button is pressed on channel 1 in order to assign that channel to the main mix. Make sure the channel 1 fader is up. Make sure the MAIN MIX faders are up. Make sure channel 1 MUTE button is not pressed. Make sure there are no SOLO buttons pressed on any of the channels.
XENYX X1832USB signal routing notes
1832 Application Guide One
An overview of input channel controls
Starting from the top of the channel ‘strip’ for channels 1 through 6:
(Note: Many of these controls are covered in greater detail (with examples) in the application guides that follow)
MIC input XLR balanced connection for a mic or similar low impedance signal
LINE IN input ¼” balanced (TRS) or unbalanced (2 -conductor) signal
INSERT jack a ¼” TRS 3-conductor jack (located on the back of the mixer) that acts as both a send and return to be used with a processor, like a compressor or effect unit. A special insert Y-cable is used, with a ¼” Tip/Ring/Sleeve on one end, and two ‘mono’ 2-conductor (Tip/Sleeve) connectors on the other end.
LO CUT button when this is pressed in, it engages a filter that cuts the low frequency range at 75 Hz and below, to remove stage ‘rumble’ and similar sounds.
GAIN knob controls the input level for MIC and LINE inputs
EQ HI knob used to boost or cut the high frequency range
EQ MID knob used to boost or cut the middle frequency range
EQ FREQ knob use to select the center frequency to be controlled by the EQ MID knob
EQ LO knob used to boost or cut the low frequency range
MON knob controls the level sent from the channel to the MON bus
AUX 2/FX knob controls the level sent from the channel to the internal FX bus, or it can be sent to a ‘post’ fader AUX send bus
PAN knob used to define where the signal is placed in the stereo ‘field’
MUTE button allows you to silence the signal in the channel
CHANNEL FADER used for adjustment of the channel output level
SOLO button used in conjunction with the MODE button in the MAIN section to select access of the SOLO or PFL functions.
SUB button is used to route the signal from the channel to the 1-2 SUB pair
MAIN button is used to route the signal from the channel to the MAIN MIX buss
Channel 7-14 inputs:
(These input channels function the same as channels 1-6, except where noted below)
LINE 7 ¼” jack will accept either a TRS balanced or TS unbalanced connector for the Left side of a stereo pair of inputs. If the LINE 8 jack isn’t used, the LINE 7 automatically serves as a ‘mono’ signal.
LINE 8 ¼” jack will accept either a TRS balanced or TS unbalanced connector for the Right side of a stereo pair of inputs.
LEVEL button selects use of either +4 level (for connection from a sound system or recorder) or -10 level (compatible with home stereo equipment).
NOTE: Stereo channels 9/10 through 13/14 function the same as the 7/8 channel pair shown above.
