The problem

Media Position is not synchronized correctly or updated frequently enough between MusicAssistant (MA) and HomeAssistant (HASS).

When adjusting the position of the current track in the MA web UI using the progress slider, the position is sometimes not transmitted to HASS or is not transmitted correctly. The same problem also exists the other way around.

Since the media_position is not updated regularly, it is only estimated in HASS based on the timestamp (media_position_updated_at), and there may be discrepancies between the progress indicator in HASS and MA.

It would probably be more robust to synchronize progress at a minimum interval of 10 seconds, for example.

How to reproduce

Change the progress bar in mediaplayer states via the Web-UI of MA or HASS and observe the reaction on the other side.

can confirmed,

Jumping via music-assistant UI, results in random progress added to Home Assistant e.g.:

the other way around does not work too, Home Assistant sends the correct seek and
music-assistant shows it, but the Home Assistant UI jumps all over.

This is extremely notifiable if you seek back in time.

It would probably be more robust to synchronize progress at a minimum interval of 10 seconds, for example.

That is not allowed by Home Assistant, the time must be calculated, we may not push it regularly (to prevent overloading the state machine).

We'll see if we can fix this (that HA displays the wrong value) at some point
