Hi All, Yesterday when I opened the issue I forgot to provide the information printed on the serial console where you can see errors in the gstreamer library.
The gstreamer version we use is 1.14.4 Today I repeated the same operations described yesterday and the problem “the music playback becomes really choppy”carose again.
I attach the logs. Log_serial_14oct20.txt logs_14oct20.txt

Hi @Lmau3 thanks for posting.
Do you see this issue every time when you pause and resume playback for Amazon Music? Testing on Ubuntu 1.17 I am not able to reproduce the same issue.
Looking at your logs I do not see any issues with downloading or buffering the audio data. Have you made any changes to the gstreamer mediaplayer that could result in choppy audio? The logs you sent for gstreamer appear to be cutoff.
Hi @womw thanks for your reply.
You can find my answers in Italic character.
Do you see this issue every time when you pause and resume playback for Amazon Music? No this problem does not present every time, but after a series do pause and resume playback, unfortunately the number of these steps is not always the same but variable.
Testing on Ubuntu 1.17 I am not able to reproduce the same issue. Looking at your logs I do not see any issues with downloading or buffering the audio data. Have you made any changes to the gstreamer mediaplayer that could result in choppy audio? No I didn't make any changes to the gstreamer or mediaplayer, they are the original ones of avs-device-sdk 1.17.0.
The logs you sent for gstreamer appear to be cutoff. The fact that you see the cutoff log of gstreamer is definitely my mistake in the log capture.
Today rerun the tests and as you can see in the gstreamer log below you can see the complete line message.
Hello @Lmau3, Are you still experiencing this issue? Are you seeing this on the latest SDK Version?
Hello @blazusiak-amazon , For now I have completed the update of my device to SDK version 1.25 and now I am continuing to update to 1.26. The problem (Music playback becomes really choppy) seems a bit improved, in the sense that the problem is generated only the first time the playback of a music is paused after a period that the device is in stand-by mode. The problem (music playback becomes really choppy) seems a bit improved, in the sense that the problem is generated only the first time you pause the playback of a music, after a period that the device has been in the stand-by mode (> 5 minutes) . At the second pause and then resume command, the music plays correctly. However I will keep you updated once complete update of my device to the version with sdk 1.26
