Album Art display inconsistent in "My Sonos" screen?

Hi @caesar327.

Thank you for reaching out.

This is really odd that the album art is not showing properly in your Sonos application.

Here are Sonos album art limitations:

• album cover should be up to 320kb in size on iOS and Android (with no resolution limit).
• JPG, GIF, PNG, BMP supported for the embedded images.
• JPG & GIF supported for folder.xxx (only one folder.xxx file per folder).
• If both embedded image and folder.xxx exist, Sonos will use the embedded image.

You may also find this support document-link worth a read. Missing music library album art in the Sonos app.

Let us know if it works. If you need help with any other information, please be sure to let us know.

To clarify, the album art is NOT from my own Music Library, so I don’t control the sizes or types of images.  This is from songs added to My Sonos from Apple Music and/or Amazon Music directly. 

Also, keep in mind that the art displays correctly in a track list, in a play list and while the music is playing on the “now playing” screen in the Sonos app.  So it must be the right size/image type.  So something else is going on here. 

Why would an Amazon Music song display art in one part of the Sonos app, but not another?  As I mentioned, it generally fails to display (on certain songs/albums) only on the “My Sonos” main screen (the screen you see when you press the STAR button.   But it displays correctly within a Sonos Playlist, within a Sonos track list of the album, and when actually playing the song (on the “now playing” screen).

Also, keep in mind that this happens with different songs that are part of the SAME album.  As an example, see below screenshot for the song “Yer So Bad” by Tom Petty.   It is part of the same album as the song “Runnin Down a Dream”.   Yer so Bad does not display art on the song list, while Runnin Down a Dream does.   Also, as you can see, simultaneously, Yer So Bad IS displaying correctly on the “now playing screen” -- shown in mini version on the below screenshot (playing to my Office Sonos One):

Hi @caesar327.

Thank you for replying back to us.

Can you also check if there’s any pending update for your Apple Music & Amazon Music application, make sure also that your phone software is up to date.

How about other music subscription? 

Might as well submit a diagnostic report. Not sure if this is also related to your music subscription also since I tried to search the apple community and there are a lot of customers reporting the same issue.

Let us know if it works. If you need help with any other information, please be sure to let us know.

Interestingly, I opened up the Sonos App on my PC, and it populated the missing album art there.  I then went back to the iPhone app, and the art was now there.   So somehow, using the Sonos App on my PC (which I rarely use), “fixed” this.  We’ll see if its permanent or something temporary.  But I assume this isn't expected behavior within/between different forms of the Sonos app?

Hi @caesar327.

Thank you for your feedback.

That's odd that your album art now all sync after using the app in your PC. we will go ahead and further investigate this, we will update the thread if theirs any new update related to this concern. 

If you need help with any other information, please be sure to let us know.

All controller apps cache album artwork locally. Generally a PC can get the art more quickly than a mobile device, so will usually seem “quicker”. From your description it seems there was some kind of network issue on mobile, causing slowness of cache filling. Hard to be sure though.

FYI just because two tracks are from the same album doesn’t mean they will be the “same” artwork - music services often use crazy urls for art tied to the track id, not the album, so although they look the same and are probably the same file on the server, may well be exposed as a different url to clients.

Actually (note for moderator), the answer above may not be entirely correct as far as the particular issue - so not sure it should be labelled “answer”).  This issue kept re-occurring.  I would then load the PC version of the Sonos App, watch it re-populate, and then it would re-populate in the iPhone app immediately as it populated on the PC version of the app.  This was always a fix (temporarily).  So this morning I simply deleted and re-added to Sonos (on my phone) the songs/albums that were having the issue (it was generally the same ones).   So far all is well.  But we’ll see if this is a permanent fix.  

What is weird though, is why would the same art show within a list (like a playlist) on the iphone app, but not on the main “favorites” screen?

My experience is similar on S2. Album art can take a while to populate, and when it does it may show the correct art in the queue but the now playing screen may show no art , or the art from the previous song in the queue ( it has sometimes being correct then reverted back to the previous songs artwork )

This is only a recent problem but not sure if S2 related or due to recently removing my wired bridge and going Wi-Fi only ( though my mesh network is very reliable but not sure if the loss of the bridge is more a factor than the S2 upgrade) 

 NB- all my music is on a Local NAS and artwork is fine in iTunes and as it’s correct in the queue I’m assuming all the bits are in the right place. 

controlav is the author of several third party apps for use in controlling Sonos. While I suspect he doesn’t have access to the Sonos code base directly, I feel fairly confident that he knows what he is talking about. 

I recall the controller can request art in different sizes, depending on where it is to be displayed. On the PC app there were really only two sizes: little ones in the list view, and the bigger one on Now Playing. The Favorites screen likely prefers a larger graphic than the playlist list view, which may effect the fetch of the art and its caching on the device.

(My own apps only ever grab the default size no matter what, because I like a simple life and bandwidth is cheap these days).
