Sonic Analysis will not initiate

Hello, first time poster, so apologies for any missteps.

For approximately the past year I have been using PlexAmp with no issues other than a complete lack of Sonic Analysis data.

The server has a Lifetime Plex Pass, and under Settings > Library, “Analyze audio tracks for sonic features” is set to “as a scheduled task and when media is added.” I have also enabled the Sonic Analysis option for the music library in PlexDash.

When I attempt to analyze the music library, I see alerts such as “Finished processing Artist / Album / Track #” and the Plex logs show tracks entering and leaving the “analyzing” state, but no Sonic data is ever generated. In PlexAmp, every track reports that Sonic data is missing.

I have also tried:

  • Manually selecting “Analyze” on the entire music library.
  • Refreshing metadata for the library.
  • Expanding the Scheduled Tasks window from 00:00-23:00 to allow analysis to run throughout the day.
  • Restarting Plex Media Server multiple times.

I was told that CPU architecture could potentially be an issue, but this server is running natively on Ubuntu and uses an Intel N150 CPU (x86_64), which I believe should be supported.

Server information:

  • Plex Media Server version: 1.42.2.10156
  • PlexAmp version: 4.12.4
  • OS: Ubuntu 24.04.4 LTS
  • CPU: Intel N150 (x86_64)

I’m hoping someone might be able to suggest next steps of things to try?

Is the account the server is claimed with different than the one you used here? (It’s missing the Plex Pass badge.)

Yes, sorry for the confusion. We have a few different Plex accounts in the household, and the account I’m posting from is not the account that owns/claims the server.

The server itself is claimed by a different account that has a Lifetime Plex Pass. I’ve confirmed that the server owner account has an active Lifetime Plex Pass subscription. In hindsight, I should have posted from the server owner account, as I have access to all of the household accounts.

You will only see the results of sonic analysis after all items in the library have been analyzed completely.
