What do you mean by "new version"? Is it the current git master version,
or Pulseaudio 1.0 with a single patch applied, or something else? The
"10 second problem" should be solved by this patch:
http://cgit.freedesktop.org/pulseaudio/pulseaudio/commit/?id=cb9ebeffa06ea63415a5f4af349f8c8c921e6673

That patch will reduce the maximum latency from 10 seconds to 2 seconds.

You could try playing with the --latency-msec parameter for the
recording side. If that doesn't do anything, try also using it for the
playback side, but at least in theory the playback latency shouldn't
affect the delay of when the playback audio starts.
