We are using using Scratch 1.4 (NuScratch) in a community tech centre in South Africa.
We recently performed a raspbian update/upgrade (install from - NOOBS_v3_0_0 November 2018) :
sudo apt-get update
sudo apt-get upgrade
The update has broken Scratch 1.4 projects. The issue appears to be related to audio. Projects were thoroughly tested and used prior to the update, and exhibited none of the current issues.
We have observed the following:
a.) projects run fine initially and output audio is expected
b.) at different points in different games the audio becomes locked up and stops playing
c.) the script running the audio file at the time maintains a white border, indicating it is still active (when it should have returned)
d.) once the audio becomes locked up, clicking play on a sound file in the sound pallet doesn't output the file; the play time goes to 0.00.00 and stays there; the time remains white (doesn't change back to black to indicate completion)
e.) other scripts not using audio appear to work fine after an audio lock up
f.) performing a clean install of the original NOOBS_v3_0_0 November 2018 release solves the problem.
g.) the issue was found on all the updated Pi.
Can anyone help?
