Sonos Controller - Duplicate Album Titles

New software just arrived so I guess we should see if it makes any difference… 

​@Corry P Ok, so have updated and all my products are showing software 

Version: 18.0 (build 93173190)

Previously, the Era 300 was on 92.0-72171, and the other speakers 92.0-71170

As the Era 300 reboots the fastest it became the associated product and a re-index resulted in the same  result as above. I powered off the Era 300 and the One SL became the new associated product and produced the same result as above.

Well I tried the removal & add of the library as suggested, I also switched all speakers off except the Play 3. The result… now I have 5 albums duplicated, each of the duplicated albums has the same one track in each duplication. DOH! I knew I should have left well alone, as prior to this I had only one album duplicated! 

I agree with Ian regarding Sonos support, I’ve been down that road, I called on the 14th of October 2025 @ 13:48 when I first noticed this problem, after an hour of trouble shooting I was told that a higher level tech would contact me, it didn't happen. 

As for the new software I’m not going to hold my breath.

​@Anthony_6 - It’s possible that turning off the Play:3 and using a different speaker to just re-index may get you back to where you were. My system is at least consistent on what is mis-indexed by speaker if I don’t touch anything else. 

I feel this is more subtle than just tagging correctly, for example I have noticed interactions with indexing and composer tags. I also suspect that library size may have an impact as the issue seems to drift across artists…

Again the desktop app is consistent and seems to work much better with sensible, and expected, search results being returned. Maybe it is not the fundamental indexing at fault but the interrogation mechanisms of Android vs iThing vs Windows vs Mac apps?

Either way it is neither consistent or right... yet 🤞

Like you I've just made a list of the affected albums, when using the Play 3. I’m going to turn off the Play 3 & turn on my Port & re-scan, just to see what happens, nothing to lose but time eh 😊

My results are all posted from the Mac App which has not changed/updated, so is consistent. The iOS and iPad Apps also match what the Mac one shows which would seem to indicate this is an issue with speaker software as that is the only thing changing. (It’s just easier to screenshot and type on the Mac). It’s the speaker software that does the indexing and propagates that around the individual Sonos speakers as far as I understand it. The controllers just query the speakers and then access the ‘source’ for album art as required I believe. 

I use the Windows version for much the same reasons.

Hi All

The steps I documented on my guide helped for the 5 albums I had that were not displaying correctly (on all Windows and Android - I can’t test anything else). Given what ​@Ian_S has illustrated, it does seem that there is an additional issue we need to address. For this to happen, there needs to be existing support cases documenting the issue. For this reason, I recommend that anyone for whom my guide does not help get in touch with our support team to document the issue. As mentioned above, I recommend that you refer the agent you speak to to this conversation in order to bypass any suggestions that they will likely give in the first instance.

​@Ian_S - regarding your discount voucher, please contact our sales department.

Hi, I think I may have stumbled on something. If I remove & add my library using the browse option it adds my server under its server name. I then get six albums duplicated. When I manually add the library using my server IP address I get one duplicated album. I’ve tried repeating it and I always get the same six or one album depending on use of IP address or name.
