Bug report: Gcompris audio suddenly stops working, plays too fast and cuts off voices

[Matthew Hoffman <matthewchoffman@protonmail.com>]

To whom it may concern:

Gcompris worked for months on by Debian 11, then the music started to
play very fast and voices got cut off before the end. It has made it
impossible to use some functions. What happened?

Thanks,
Matthew Hoffman
