using pthread to receive data on a socket and simultaneously

| Hi,
I am writing a client for a real time audio streaming server. I am
using pthread for that. I have one thread receiving data on a socket from
the server. After buffering some data, other thread wakes up (checking how
much data is in the buffer) to play the music. The problem is that when the
2nd thread is playing, the first thread is not able to receive data from
the server. If the server sends the data slow, then there will be breaks
in the audio. How do I solve this problem?
Thanks.

The player thread has to yield the CPU at some point to let the receiver
run. If this isn't happening, your player must be using 100% CPU.
Appears a bit excessive for a music player.

There's probably something wrong with your code. Perhaps your thread is
holding a lock on the buffer while it's playing the music?
