Slow volume fade-in when playing audio tracks

Question

I have a system running fresh installed Ubuntu 14.04.1

When a music track starts to play, the volume is gradually increased. It takes about 2 seconds to hear anything and 3 seconds to reach full volume.

When playing short tracks this is really annoying.

Is it a pulse-audio setting? How can I make the volume increasement go faster?

Thanks for your response.

I tested the following applications:

As far as I can see all (sound related) applications suffer from this.

What program are you using to play the music? Does it happen with any program? — Nattgew, Dec 15, 2014 at 20:13
Have face the same problem while playing any video file as well? If possible, try to reinstall the audio drive and check it once again. — vembutech, Dec 15, 2014 at 20:41

I think this is due to pulseaudio suspending the respective audio interface, presumably for power saving reasons.

Try editing your pulse audio config (for me /etc/pulse/default.pa) and comment out this line to disable this feature:

load-module module-suspend-on-idle

Then restart Pulseaudio:

pulseaudio -k

I had a symptom where Ubuntu audio starts silently "ramps up" in about 2 seconds, including the test sound from the system sound settings. After removing the module noted above, sounds play crisply and right away. Thanks.
