Unable to hear sound from my laptop

I have Vista (which I was told will work) and using an AT PL50 Audio Technica turntable and a Behringer UCA 202 adaptor using Audacity 2.x. I have put the “sound” on to the USB speakers, when I just monitor the LP, I do not get any sound out of the laptop but I do have 2 green bars L & R) but only 1 red bar or left speaker. Wehn I hit record, I still do not hear any sound. Software play through and sound activated recording is on. Help!

You can set the Audacity playback device in Device Toolbar to Behringer USB CODEC but you will then need to listen by attaching headphones to the Behringer.

It is probably more convenient to set the Audacity playback device to the computer sound device or to separate USB loudspeakers that connect to the computer (if that is what you mean).

You won’t hear any sound from recording or monitoring unless you set Transport > Software Playthrough (On / Off) to on, but you should turn Sound Activated Recording off.

If you only have one red bar then you are recording in mono. You can change to stereo recording in Device Toolbar. Also you must perform the following steps to make sure Windows records in stereo:

  1. By the system clock, right-click over the Speaker icon > Recording Devices then right-click over USB Audio Codec > “Properties”.
  2. On the “Advanced” tab, in the “Default Format” section, make sure the drop-down menu is set to “2 channel 16 bit 44100 Hz”.


I have it set on MME, speakers USB audio CODEC, AT turntable and 16 bit 44100 stereo. Still no sound out of laptop. I did try headphones in the jack on the UCA202 but still no sound. I do have both L & R working on the green lights and the red lights. What else could I try? Thank you.

We can’t see your computer so please describe how you are connecting the turntable and Behringer to the computer and what these “USB speakers” are. Are they separate USB speakers for plugging into the computer?

Assuming you don’t have any separate USB speakers but want to listen to the turntable playback in the computer’s own speakers, and that this computer has no line-in (only a mic input or no inputs):

  • Connect the red and white cables of the turntable to the L and R inputs of Behringer (not the L and R outputs).
  • Connect the USB cable of Behringer to an empty USB port on the computer.
  • Set the Audacity Device Toolbar to:
  • MME
    • Output Built in Speakers (this may not be what it is called but it is the audio output of the computer - you can choose the computer headphones instead).
    • Input Behringer USB Audio CODEC (or similar name).
    • Recording 2 channels stereo.
  • Turn up both sliders on Audacity Mixer Toolbar:

  • Turn on Transport > Software Playthrough (On/Off).
  • Click in the red recording meter to monitor the sound then you can hear the turntable before you press the Audacity Record button.
