Still an issue in Matheria 7.2.2.4 (server version 32.0.5).

This also manifests a bit differently when using the lock screen player: resuming playback after the call actually skips back to to the start of a previously played track instead of resuming the current one (from where you were when the call came in). The player even shows the current track title, despite playing a different one.

Steps to reproduce this variant:

1. have a directory with two audio files, 1.m4a and 2.m4a
2. start to play 2.m4u
3. lock the screen
4. call the phone (just have it ring, then hang up)
5. resume playback from the lock screen

Expected behaviour

Playback of 2.m4a resumes from where it was when the call came in

Actual behaviour

The player beings to play 1.m4a from the start (but claims to play 2.m4a)
