This is generally a symptom of your sound driver not supporting full
duplex audio, you might check into this.  This is one of the reasons
alsa is recommended.  The backend opens /dev/dsp to record the audio and
the frontend is not able to open /dev/dsp for output due to it being
open already.

Hope this is helpful.
