another tip for #pinephone #mobian users:::

(Updating ringtone)

Per the wiki:
"The default ringtone for Mobian Phosh can be found at /usr/share/sounds/freedesktop/stereo/phone-incoming-call.oga"

My immediately solution is to run (within the /stereo/ folder in terminal) 'mv *.oga incoming.oga.old' and move/copy a new *.oga file in its place. If you don't have a *.oga ringtone file ready, you can *try* and use ffmpeg to convert it. After conversion, rename it to the original filename and place it back accordingly.

Eg.)
"ffmpeg -i SomeAudioFileBlah.mp3 phone-incoming-call.oga"

^^^ converts Some...mp3 to phone...oga
