@metagross31 I'm on Mint 20.3 (Mate), installed via PPA, and I never had this issue.
Just shooting in the dark here, but did you install Strawberry through the Software Manager or by following PPA instructions on Strawberry's main site? Is anything listed when you click the "Collection" button? Have you tried adding something to the playlist pane?
@fatso Found it. Thanks for the info!
For anyone else looking for this, on Mint linux 20.3, the full path is:
/home/your_user_name/.config/strawberry/strawberry.conf
(.config is hidden, so use CTRL-H to see it)
@cherrystraw I can't speak to the program coding involved, but a new DB field (possibly in playlist_items ?) would get the ball rolling...although I'm certainly not telling Jonas anything he doesn't already know.
@fatso AWESOME! Thank you so much. I'm a total newb with this streaming stuff...can ya tell? LOL
@jonas For clarity, are you saying I need to enter a web page URL (my example is exactly that), or that my example isn't a stream? Also, how can I determine the audio format of an online radio station?
Thanks for your time. 
The title says it all. I save my playlists in a folder of my choosing, so I already know where they are, but I can't locate custom EQ presets...not even in the database file.
If something were to go horribly wrong, it would be very handy to have backups to restore from, especially in the case of EQ presets. (or at least know where they are located for manual backup/restore).
Whenever trying to add a stream, I get the error "GStreamer installation is missing a plugin".
Any way I can get more specific info...like WHICH plugin is missing? There are tons of them, so I'd like to know which one I need.
BTW, I believe I am inputting the proper URL for the specific radio station I want hear.
ie: https://tunein.com/radio/Rebel-1017-FM-CIDG-FM-Ottawa-ON-s106243/
Any help would be very appreciated.
1st, let me say this software is mind-blowing!!! Fantastic work!
Since I have an extensive music library and EQ presets for almost every album, it would be really nice to be able to "link" each album with its preset so I don't have to manually select the right preset for each album. In other words, when I load an album to play, have its designated EQ preset automatically selected. Is that do-able?
