patch to add reset logic to sunaudio sink and source plugins
Padraig had the following comments today:
have spent some time trying to understand what happens when the Stop button is
pressed in an application which is playing audio.
The test case I am using is gnome-sound-recorder. I record some sound and then
play it back. Is there a better test case I could use?
I am seeing that the callback for the Stop button takes about 1 second to run
and most of this time is spent in the close system call in
Strangely, I am finding that the segsize and segtotal setting for the
ringbuffer does not seem to affcet the time taken in the close system call.
I wrote the attached patch which adds a reset function to the source and sink
plugin. This seems to greatly speed up the performance of hitting the
I think we want this patch and also to continue working on the patch so that we
no longer need to set segsize/segtotal to a large buffer on Solaris.
This patch fixes the problem of stop/pause being slow, but changing volume is
still very unresponsive.
We need the patch so we no longer need to set segsize/segtotal to improve the
performance of changing volume.
