[MPlayer-users] Mencoder problem with /dev/dsp

[Prakash Sompura]

Thanks. I corrected my command to the following. But the error message has
been changed to little, probably which also shows that /dev/dsp is  busy. I
have pasted both below. I believe I have done some mistake in configuration
of /dev/dsp device but I am not able to figure it out.
