           Summary: Shorter-than-prebuf streams are silent if started
                    corked

          Severity: normal
    Classification: Unclassified
                OS: All
          Reporter: tanuk at iki.fi
          Hardware: Other
            Status: NEW
           Version: unspecified
         Component: core
           Product: PulseAudio

If a stream is shorter than prebuf, and the stream is started in the corked
state, its audio will get discarded when uncorking.

I'll attach a program that reproduces the issue, and a fix for the bug. The fix
is a quick hack, and probably not suitable as the final solution. I haven't
investigated the root cause myself that deeply yet, but I was told that the
audio gets discarded during rewinding, so the proper fix probably involves
modifying the rewinding code.

How to compile test.c:

gcc test.c -std=c99 $(pkg-config --cflags --libs libpulse) -lm -o test
