[Touch-packages] [Bug 1477838] Re: Crackling sound after playing audio and suspended

[Jonas]

I don't know if it is relevant, but I use whatsappweb with lifecycle
exception and both my mx4 and my m10 play the tick sound all the time,
as soon as I turn the screen off.

Bug description:
  The Meizu MX4 is doing a weird "tic tic tic..." after receive a
  notification (from telegram, mail...) and it's suspended.

  --

  When I press the screen lock button on the MX4 shortly after playing
  music or ending a phone call I hear a radio/fuzzy distorted noise
  coming from the phone. To make it stop I need to unlock and lock the
  screen again but this is not ideal.

  -

  When the screen is locked and the playing song is finished and waiting
  for a stopped signal, MX4 will do a weird lower sound.

  -

  TEST CASE (Thanks to Kamikaze)
  1. Boot the device and wait until it suspends (black screen)
  2. ssh to the device
  3. Run from the command line:
    $ aplay /usr/share/sounds/alsa/Front_Left.wav
  4. Repeat step 3 until you reproduce the issue (3 to 5 times)

  --- Original Case ---
  How to reproduce (Note this does not always work, the phone needs to be in 
some specific state yet to be determined)

  Ensure MX4 is not plugged into USB
  Call the MX4 and hear the ringtone
  Dismiss the call
  Push the power button to turn off the screen
  Tick Tick Tick
  Push the power button to turn on the screen
  hissing
  Push the power button to turn off the screen
  Tick Tick Tick
  etc

  It will not clear until you play another sound
  Does not happen in silent mode of course

  --from the dupe 

  Aquaris E4.5

  Steps to reproduce:

  1. Start playing a podcast.
  2. Switch to a different app.
  3. Lock the screen.
  4. Wait for the Podcast to finish.
  5. Wait a bit longer.

  Expected results:

  No noise from speaker.

  Actual results:

  Soft white noise from speaker. It seems that some part of the audio
  subsystem is still switched on. I am concerned that this could be
  draining battery.

  Workaround:

  After the Podcast finishes, unlock the phone and switch back to the
  Podbird app. This causes the noise to stop.

  Comments:

  I noticed the same soft white noise continues a second or two after
  the phone plays any sound from any app, but then turns off. I presume
  there is some time out turning off some part of the audio subsystem.
  Presumably if there is a reason, it should happen even when the app
  causing the sound to play is not active.

> than an annoying noise happening, which seems to be MX4 specific.

@John: I have Nexus4, BQ E4.5 & MX4 and this is happening only in MX4.
FYI, I flashed this week the MX4 and set the default notification
sound, but same weird sound.

A hug.

[Touch-packages] [Bug 1477838] Re: Crackling sound after playing audio and suspended

[Robie Basak]

This isn't MX4 specific. I'm affected and I have an Aquaris 4.5. See
duplicate bug 1445527. My issue is not the noise itself, it is that it
doesn't stop if the screen is off when music finishes and that this
causes battery drain. If this isn't what you want to track in this bug,
then please undupe my bug.

[Touch-packages] [Bug 1477838] Re: Crackling sound after playing audio and suspended

[John McAleely]

"I noticed the same soft white noise continues a second or two after the
phone plays any sound from any app, but then turns off. I presume there
is some time out turning off some part of the audio subsystem.
Presumably if there is a reason, it should happen even when the app
causing the sound to play is not active."

So, I believe pulseaudio, by design, maintains active status briefly (ie
a second or two) when a connection from an app terminates, so that if
two sounds a played back to back there is continutity for the underlying
hardware.

I think that's a separate bug (and possibly by design) than an annoying
noise happening, which seems to be MX4 specific.

Sadly, so far, finding people with the deep knowledge of the android
underpinnings of MX4 is proving tricky.

  When the screen is locked and the playing song is finished and waiting
  for a stopped signal, MX4 will do a weird lower sound.

  TEST CASE (Thanks to Kamikaze)
  1. Boot the device and wait until it suspends (black screen)
  2. ssh to the device
  3. Run from the command line:
    $ aplay /usr/share/sounds/alsa/Front_Left.wav
  4. Repeat step 3 until you reproduce the issue (3 to 5 times)

  --- Original Case ---
  How to reproduce (Note this does not always work, the phone needs to be in 
some specific state yet to be determined)

  Ensure MX4 is not plugged into USB
  Call the MX4 and hear the ringtone
  Dismiss the call
  Push the power button to turn off the screen
  Tick Tick Tick
  Push the power button to turn on the screen
  hissing
  Push the power button to turn off the screen
  Tick Tick Tick
  etc

  It will not clear until you play another sound
  Does not happen in silent mode of course

  Soft white noise from speaker. It seems that some part of the audio

  draining battery.

  Workaround:

  After the Podcast finishes, unlock the phone and switch back to the
  Podbird app. This causes the noise to stop.

  Comments:

  I noticed the same soft white noise continues a second or two after
  the phone plays any sound from any app, but then turns off. I presume
  there is some time out turning off some part of the audio subsystem.
  Presumably if there is a reason, it should happen even when the app
  causing the sound to play is not active.

@z-admin-angels-gmail-com - are you saying it makes a brief ticking
noise after playing a podcast? And would you know, if you are asleep?
:-)

Otherwise this sounds like a different bug
