Unable to Scrobble with Navidrome

[typhoon2099]

I'm seeing errors in Navidrome's logs when syncing. It appears that listens are being rejected by both Last FM and ListenBrainz due to the timestamp being incorrect:

I'm not sure if it's related, but I'm currently unable to sync playlists to my watch. When I try to sync I get a GarminSdkError::-403.

I'm also not sure if this is related, but I've had a few crashes with SubMusic. If I don't go into the menu and specify the playlist I want (ie just try to play whatever is there after switching providers to SubMusic), then the watch hangs and then restarts. It happened near the end of a run, which thankfully Garmin was able to resume after restarting!

The -403 error means that the network response is out of memory. Which device are you using and is it correct that the playlist you try to sync is more than about 15-20 songs? This depends on the available metadata that is included in the song files or library. This error is unrelated to the rest of this response.

With respect to the scrobble issue, I see the timestamp sent to the endpoint is: 1970-01-21 08:08:07.056 +0100 BST, right?
Converting to GMT:
Date and time (GMT): Wednesday, January 21, 1970 7:08:07 AM

In UNIX seconds this would be 1753687. Now, suppose Navidrome assumes it receives timestamps in milliseconds instead of seconds and SubMusic actually sent 1753687056 (going by the milliseconds given above). Then, the actual time should have been:
GMT: Monday, July 28, 2025 7:17:36 AM

So, Garmin / SubMusic is counting seconds, while Subsonic API expects milliseconds. I also checked the other APIs, for Plex a timestamp parameter is not known, so not applicable. For Ampache API, the date parameter is actually measured in seconds, so no issue there. For Emby API, the date is in a custom format, so also no issue there.

Will fix the issue for Subsonic API in the next version!

I'm trying to sync 4 playlist of between 11-14 songs. I have synced some of them previously. Does the limit apply to all of the playlists or each one individually?

[memen45]

For the set of playlists (so, the metadata related to the playlists you have, combined), but also per playlist (the metadata of all the songs inside that playlist). Also note that this is a Subsonic API limitation, as paged requests are not possible. For Plex, Ampache and Emby APIs, the requests are dynamically paged by the SubMusic app.

If you are able to browse and select playlists, it is most likely the songs metadata that is limiting. This can be additional information like lyrics, biography info etc.? This quickly adds up and lowers the limit. The memory limit is also not fixed, as there may be other apps running, Garmin watch software has been updated or other apps have updated. On top of that, the total available memory is different for each watch model.

Only solution for now: smaller playlists. If it does not work, please send me an email through the Contact Developer option, so we can check in more detail. I will keep this issue open until the new version of SubMusic is released.

Thanks for opening the issue and sharing the logs. Very helpful to find out the issue quickly,

[typhoon2099]

Thanks is for the help. My music is all tagged via MusicBrainz, so quite possibly has a lot of metadata attached. I'm surprised that the information is needed I'm the playlist endpoints, I would have though it would be down to players to read it from the transferred files.

I'm using a Forerunner 965 btw

@typhoon2099, thanks for adding the MinimalClients option to Navidrome! It’s made a huge difference: playlist fetching on my smartwatch is much faster now.

[typhoon2099]

@cristianpb Does it work fine for you? I've just tried to sync and I can only get SubMusic to sync one playlist (it does the first one, no matter how many playlists you select), and it says that that playlist needs to be synced as soon as it's done...

EDIT: I have it working now, but I had to set the environment variable for it:

ND_SUBSONIC_MINIMALCLIENTS: "SubMusic-v0.2.12-orestes"

there's a default value of SubMusic, but for some reason that isn't working. I'm sure it does partial matching for Legacy clients, so possibly something to look into.

[cristianpb]

Correct, defining the clients explicitly is necessary to make this work, as you pointed out.

      ND_SUBSONIC_MINIMALCLIENTS: "SubMusic-v0.2.12-orestes,SubMusic-v0.2.10-hippocoon"

Then I see the difference using a random client

# curl "https://SERVER_URL/rest/getPlaylists?p=PASSWORD&c=NavidromeUI&u=USER&v=1.10.2&f=json" | jq

{
  "subsonic-response": {
    "status": "ok",
    "version": "1.16.1",
    "type": "navidrome",
    "serverVersion": "0.60.0 (0c8f2a55)",
    "openSubsonic": true,
    "playlists": {
      "playlist": [
      ....
        {
          "id": "8654651e-7f8b-4973-9626-b91f4064732b",
          "name": "playlist_name",
          "comment": "Auto-imported from 'playlist_name.m3u8'",
          "songCount": 100,
          "duration": 18374,
          "public": true,
          "owner": "USER",
          "created": "2023-04-26T06:30:12.80854326Z",
          "changed": "2026-02-04T21:06:08.573740059Z",
          "coverArt": "pl-8654651e-7f8b-4973-9626-b91f4064732b"
        }
      ]
    }
  }
}

and a client using SubMusic

# curl "https://SERVER_URL/rest/getPlaylists?p=PASSWORD&c=SubMusic-v0.2.12-orestes&u=USER&v=1.10.2&f=json" | jq
{
  "subsonic-response": {
    "status": "ok",
    "version": "1.16.1",
    "type": "navidrome",
    "serverVersion": "0.60.0 (0c8f2a55)",
    "openSubsonic": true,
    "playlists": {
      "playlist": [
      ....
        {
          "id": "8654651e-7f8b-4973-9626",
          "name": "playlist_name",
          "songCount": 100,
          "duration": 18374,
          "created": "2023-04-26T06:30:12.80854326Z",
          "changed": "2026-02-04T21:06:08.573740059Z"
        }
      ]
    }
  }
}

[typhoon2099]

Yeah, I thought from aging around with the legacy clients options that the clients list worked with a partial match, so as long as your client starts with one of the defined clients it would work. I'm obviously mistaken, so it needs to be explicitly defined to work.

I'll add a PR to this repo with some instructions for Navidrome users.
