Comment 3 for bug 1445527

Hi Nekhelesh,

> Could you perhaps let me know how long the podcast should keep running in the background after which you can start to hear the soft noise?

It's immediate - it's audible as soon as the podcast finishes. The reason I said "wait a bit longer" was to give the sound an opportunity to stop. Maybe I should have made it clearer that the noise is very quiet?

Perhaps we first need to identify the noise I'm talking about. It doesn't just happen from listening to a podcast, and it may be more obvious to hear it for the first time when the phone is expected to be silent.

Another occasion the noise happens (I don't think this is a bug in itself) is if I go to a web page in the browser that is capable of audio even if I don't actually play the media. In this case I hear the noise start soon after entering the page (I suspect when things have loaded) and it continues for fifteen seconds before stopping (I timed it). Example page: http://m.bbc.co.uk/news/world-europe-32374005 - try entering this page by following the link from this Launchpad bug page on the phone while holding the speakers up to your ear in a quiet room (I only notice the noise at night). I hear a soft pop, then quiet white noise for fifteen seconds, and then the noise stops. You can use back and forward to try again - after pressing back wait fifteen seconds to make sure it is gone. Go forward again and you should hear the noise start as soon as the "play" button appears on the video.

Once you've identified the noise I'm talking about, you will hopefully be able to hear it at the end of a podcast also. It's more notable when it stops - so try seeking to near the end of a podcast, switching away from the Podbird, locking the phone and waiting for the podcast to finish. Then while listening unlock the phone and switch back to Podbird - the sound of the noise stopping may be more obvious.

The difference between my Browser case and my Podbird case is that in the Podbird case the noise carries on indefinitely, so the Browser case isn't really a battery drain, but the Podbird case could be, since I first noticed the noise an hour or two after a podcast finished.

I just tried reproducing on headphones. I can hear the noise start in the Browser, but it is so barely audible that I can only do this because I know when I'm expecting it. It isn't really loud enough for me to hear if the same thing happens in Podbird.
