Hi ​@mildly irritated onos owner, welcome to the Sonos Community!

I’m sorry to hear that you’re having issues with Audible on your system. 

I’ve checked with my colleagues; however, they aren’t able to replicate this issue, and the chapter select is working for them. One audiobook does play the incorrect chapter (6 instead of 12), but this is a specific audiobook issue, and all others play correctly, as well as none have the issue that you are experiencing.

Does this issue occur with all audiobooks, or is it only specific ones that don’t let you select the chapter? Can you please also test an audiobook that you were having issues with and, after the chapter selection feature doesn’t work, submit a diagnostics so we can test it on our end as well. Once you’ve got the reference number for the diagnostics, directly message me the reference number and I can ask my colleagues to check what is going wrong. 

Hi Jamie, thanks for picking this up, I'll message you the code separately. 

Yes, this occurs with all audiobooks

Hi ​@mildly irritated onos owner,

Thanks for your patience.

I’ve heard back from the team regarding this; While my colleagues in the UK can’t replicate it, my colleagues in the US can. We aren’t sure of the cause currently, whether this is account or region specific, but a ticket has been raised.

I don’t have any ETA to share on when this will be resolved but I’ve tagged this thread as having the issue and will reply if I hear anything. For now, I would recommend keeping your system up to date on the latest firmware, as if an update comes through that fixes it, you’ll likely see that before I do.

I hope this information helps!

Thank you for getting it to this stage. Is it possible for me to see the ticket? 

Also, I am in the UK, but I will go and check to make sure all my Sonos settings reflect that

Hi ​@mildly irritated onos owner, 

I’m not able to share the ticket as it is internal information which I don’t have access to it (besides the ticket number, which I also can’t share), but I am in touch with the ticket creator, the most I can do is update you here if I hear anything. If you contact our support team, they’ll be able to tag your case with this specific issue and update you once it is resolved.

I saw that your community profile was set to the UK, but we’re still not sure what causes this issue to occur and whether it is region or account specific, or something else. It still would be worth checking that your profile on Sonos.com is set to the UK, as that will determine the region of your system. Please note that it can take a few hours for the change on your profile to reflect on your system.

The support page states up to 15mins.

So it turns out that my sonos.com profile was set to the US, no idea why. I have updated that to UK now but I am still seeing the issue. Would I need to do anything to force my system to update to these new settings?

I didn’t realize this had changed, thanks for sharing with me and the OP. It used to take a lot longer which is why we’d sometimes suggest rebooting everything or checking for updates in the app to speed up the process. 

In the article shared by ​@Mr. T, the change would occur within 15 minutes, so you wouldn’t need to do anything else to update your systems region. You could try to reauthorize Audible again to see if that helps: You can do this by tapping the profile icon in the Sonos app → Content Services → Audible → Primary Account → Reauthorize Account. You could also check for updates in the Sonos app.

I do think that this issue isn’t region specific, just that the few people in the UK with Audible weren’t able to reproduce it. What’s marked as the best answer to the thread is correct for the time being: No ETA to share, I’ll update this thread if I hear anything and keep your system up to date.
