You need to install it too using apt or Synaptic.
apt install strawberry
Working now, thanks!
But not good.. although it does show as version 09.2, immediately when clicking a song to play, Strawberry freezes up completely again, just as it did in the old version.
This is completely unworkable because it not only freezes the player, but the whole pc - I have to cold start the whole desktop every time.
Most of the time that has something to do with the sound setup on your computer.
It probably freezes when it tries to open the soundcard.
Try different settings in Settings / Backend, try selecting a different device.
@jonas I'm on Mint 19.3 - there's nothing called Backend.
By the way, did you try using SysRq before you cold boot your computer?
On Linux you can usually solve most system freeze without rebooting using SysRq.
ALT + SysRq + f has saved me a lot. It kills the most memory consuming process.
@jonas that looks like very good stuff to know - will investigate it, thanks.
Still, no "Backend" in my settings.
BTW I've never had sound problems with any other player on this machine; mocp, vlc, rhythmbox, audacity..
@jonas I was looking in the wrong place - settings in Linux Mint
Now I see it is of course within Strawberry; I have 10 options and have no clue which one to pick.
The default was as you see in my attached screenshot.
Another difference with yours is: ALSA plugin hw nore plughw is ticked.
Check that you have ALSA and PulseAudio as options under Output.
Check that your soundcard is listed under device.
Try specifically selecting ALSA or PulseAudio and the device.
