[PATCH 9/9] Fixed problem of mute audio on some calls

[Andreas Eversberg]

When reading from RTP socket, the first read() may fail right after
connecting to remote socket. Subsequent read() will work as it should.

I have not discovered why this read fails, but I don't see any reason
why we should stop reading, just because one read() fails at the
beginning.
