Describe the issue

ARC fails to transfer metadata
I use ARC on Android with a 2013 Lexus which only supports AVRCP 1.3 for Bluetooth metadata. It seems ARC only transfers metadata if I start a new album after a fresh connect to Bluetooth. If the connection was recently active on the phone or if the album is already playing I get no metadata. When I do get metadata, no matter what the song # it is always displayed as 1.

Describe your network setup

Bluetooth AVRCP 1.3 MAP 1.3 (though 1.4 may work) Android 14, Pixel 9 Pro XL, though the problem also happened with Android 13 and a Pixel 8 Pro

Hello @Peter_Hunsberger ,

Thanks for reaching out with your report. Can you please let us know the exact local time + date + track when you next observe this issue? If you can please share a screenshot/picture showing the issue as well, it would be much appreciated. Thanks!

What am I supposed to screen shot? I can take a pic of the screen on the car showing no metadata but how useful is that?

Yes, via developer settings try 1.4 or 1.6

With a screenshot/photo the support team can look at yous logs time stamped by the info you provide and compare it with what’s being displayed. Sometimes a photo speakers a million words.

Android 14 defaults to 1.5, I’ve never seen metadata with 1.4 or above, the recommendations I’ve found suggested older cars needed 1.3 which worked fine until recently (like maybe a month ago).

Is this with your own library files, Tidal or Qobuz or both your own and streaming service?

If your own, do you have you CDs ripped as;

1-01 track name.flac

I’m thinking you’re seeing the CD number 1 :man_shrugging:

This is my library, tracks are ripped like “05 Mind made up.m4a” (ALAC in this case). The title shows up properly (when it shows up), but no track number.

Just reproduced this problem twice. I’m on my computer so I won’t copy the phone screen shots over, but 1st time I used AVRCP 1.6 and time was 2024-08-30 21:40. Second time I closed out the app, switched to AVRCP 1.3, restarted ARC, time was 1 minute later. No metadata either time.

Hi @Peter_Hunsberger,

Thank you for the report. ARC temporarily lost sight of your RoonServer machine around the time you connected via Bluetooth in the screenshot above. Is this around the time the phone handed off connectivity from WiFi to cellular? When you reproduced via AVRCP 1.3 in the second reproduction, did you have different connectivity conditions on the phone? What did the server connectivity status in ARC settings indicate?

We can see ARC receiving empty metadata in diagnostics, but we first want to ascertain the root cause of the connectivity problem in logs

II can’t say for sure what connection I had, that’s not on the screen shot but typically this happens every time I start up ARC, whether I’m near WiFi or only on Cellular. The only time I get metadata is when the 1st track from a new CD starts up and then metadata will continue to be shown for all tracks until I stop the car and I reconnect. I will not always start getting metadata with Track 1, but I cannot really see any consistent pattern as to why not. Today I got Metadata for track 1 (likely around 4:00 CT) but I may have already been off the property and on cellular when that happened.
