Fortunately for all of us, a new taiHEN plugin for the Vita called noAVLS, from developer dots-tb promises to vanquish AVLS once and for all.

For those of you who are unaware, AVLS (an acronym for Automatic Volume Limiter System) is a precautionary measure implemented by Sony to prevent you from listening to music above certain volumes (above 21 bars). While in theory, this is a good idea, to prevent any users risking permanent ear damage by listening to loud music for prolonged periods of time, in practice it isn't so simple; different earphones with different impedances receive radically variable volume when listening to music on the Vita, meaning that the volume will end up being inconsistent across different pair of earphones. While 15 bars may be enough on a pair of Earpods, something more expensive with a higher impedance may require you to turn it up more, which is where Sony, and their annoying AVLS which you have to turn off again every time you reboot, is causing issues.

Fortunately for us all, the open-source noAVLS plugin has come as our saviour for AVLS-enabled PSVitas. on AVLS-enabled Vita models. The affected models are:

  • Later European PSVita Fat (1000) models with a Wolfson Microelectronics WM1804E DAC.
  • All European PSVita Slim (2000) models as they have the audio DAC chip mentioned above.

Installing it is fairly straightforward and can be done by following these steps:

  1. Download "noavls.skprx" from the GitHub link below.

  2. Copy it to your Vita via FTP/USB into your taiHEN folder.

  3. Add the "noavls.skprx" file to your *KERNEL section (as it's an skprx plugin) in taiHEN's config.txt.
    Common directories are




depending on where you store your taiHEN files.

  1. Reboot your Vita and enjoy an AVLS free life! Does it feel good living on the edge?

What do you guys think? Is this the solution to the problem of AVLS bugging the life out of you? Will you install this on your Vita? Let us know in the comments, or post over in the forums with your thoughts.
