Description Dâniel Fraga 2015-01-20 20:03:41 UTC

I'm using Pulseaudio 5.0 and all applications show a delay of about 2 seconds after the audio finished playing.

I searched for Google and it's exactly like what was reported here:

pa_simple_drain() takes over 2 seconds to complete!
https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/660567

What you need to debug this?

Thanks.

Nobody?

Comment 2 Dâniel Fraga 2015-01-31 01:08:51 UTC

Still nobody?

Hi, thanks for the report. Sorry for the delay, I don't have much time to read bug reports, let alone fix them...

The problem with slow draining has been fixed, so I don't know what the problem in your case might be. Can you reproduce the problem with this command:

    for i in {1..5}; do paplay /usr/share/sounds/alsa/Front_Center.wav; done

On my machine there's no delay between the paplay invocations.

Hi Tanu, thanks for the answer. I tried the above command and there're a 2 second delay between the paplay invocations.

Do you need more information? Just ask and I will provide. Thanks.

Ps: mplayer or aplay takes longer to exit, about 4 seconds.

I'm changing this to INVALID since the problem was with the Full dynticks in the kernel. There're some problem with the full dyntick code.
