I am writing a program to play audio using 'libpulse' on linux. I have
successfully played the audio, but need to know how to change the volume. I
am able to start the stream using

pa_cvolume_set(&m_lcvolume, 1, v);
pa_stream_connect_playback(s, NULL, &attr, PA_STREAM_NOFLAGS, &m_lcvolume, NULL)

with pacific volume but need to know how to change the volume after
connecting to stream. I don't want to call pa_stream_connect_playback
function again and again to change the volume.
