AVReceive2: Unable to handle dvi/rtp

Hi,

I try to execute AVTransmit2 and AVReceive2. I execute them whit this lines:

java AVTransmit2 javasound://8000 192.168.16.183 22222

and

java ACReceive2 192.168.16.183/22222

but I have the following problem:

Unable to handle format: dvi/rtp, 8000.0 Hz, 4-bit, Mono

Failed to prefetch: com.sun.media.PlaybackEngine@13c5982

Error: Unable to prefetch com.sun.media.PlaybackEngine@13c5982

AVReceive2 internal error: javax.media.ResourceUnavailableEvent[source=com.sun.m

edia.content.unknown.Handler@e7b241,message=Failed to prefetch: cannot open the

audio device.]

Please, can someone help me?
