ARC B346 Unexpected Playback Error/Corrupt Media with 24 Bit FLAC downsampled to CD Quality

I’m suddenly running into Unexpected Playback Error/Corrupt Media errors on B346 of ARC when downsampling 24 bit flac to CD quality. The file will play on bandwidth optimized (downsampling to opus). I can provide a sample file. For reference so I remember the song is Father to a Son by Green Day at the 3 minute mark.

Hi @mackid1993, could you please provide a sample file?

Just sent one over DM

Thanks for sharing media! Tested on Wi-Fi/mobile, playing to internal speaker/BT headphones,- but with no luck. Do you recall any additional data that can help to reproduce the issue? Is it constantly reproducible on your device?

I just reproduced it now on my phone on WiFi. Timestamp 2:16 PM ET if you want to check logs. Audio was set to CD quality and I got the error at 2:53. This happened just now on my phone’s internal speakers.

@oleh Unfortunately for me it seems my Roon Server docker install is the issue. I just tested on my Windows VM (on my Unraid server) and running under Windows with my music mounted over SMB I don’t run into any issues. Seems like whatever dependency is used for transcoding in the docker image I was using is probably outdated.

Edit: I just took my docker install and restored a backup from 2 days ago into itself. Issue is gone! Seems like I had a database issue!! My docker install is okay! Not the first time I’ve had my Roon database break itself. Backups are important!

@oleh I had another track that was having issues (I could remember the album but not the song). That is resolved after the database restore. The interesting thing is this issue was occurring when this backup was taken so it was clearly the act of restoring the database into itself that cleaned something up that broke. Interestingly enough I’ve had something similar to this happen in the past and this very thing solved it. It was ages ago.

If you have any insight into why strange things like this happen I’d really be curious for my own knowledge.
