I had this issue as well, and this was the setting I changed to fix it:
View -> Options -> Advanced -> Audio -> Audio Player: Change it to something else.
There is no guarantee whether this would work or not, though, considering this bug only happened on my Mint 19.1 (with no such bug beforehand. It just happened after a long time of not using it) and not on my Ubuntu 18.04 despite both of them are using "ALSA" as their Audio Player.
