[Bug 1477838] Re: [MX4] Crackling sound after playing audio and suspended
** Description changed:
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.
-----
- How to reproduce (Note this does not always work, the phone needs to be
- in some specific state yet to be determined)
+ TEST CASE (Thanks to Kamikaze)
+ 1. Boot the device and wait until is 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)
+

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
