@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 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1477838 Title: Crackling sound after playing audio and suspended Status in Canonical System Image: Triaged Status in pulseaudio package in Ubuntu: Confirmed 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.
