NoAVLS released for the PSVita  –

Sony has always liked forcing ‘features’ on users such as the forced blacklist on the PSTV and AVLS on some PSVita models. Now, thanks to taiHEN plugin NoAVLS, you can get rid of AVLS once and for all!

What’s AVLS and what does NoAVLS do?

AVLS, which means Automatic Volume Limiter System, is a limit that is enforced on your headphones to stop them from exceeding a specified volume level (21 bars to be exact). While this is meant to protect you from permanent ear damage, it can be a nuisance when it doesn’t work correctly since some headphones require a higher volume than others since the ‘safe’ levels are too quiet for them.

NoAVLS - Disable AVLS forever!

NoAVLS is here to save you the headache of having to disable AVLS every 20 hours or when you reboot your system on AVLS-enabled Vita models. The affected models are:

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

Do note that ‘AVLS’ will still be enabled in settings with this plugin. This is normal behaviour and AVLS still gets bypassed.

How do I install it?

The pesky audio DAC chip that does the difference!

Installing it is pretty easy and can be done by following these steps:

  1. Download “noavls.skprx” from the link below.
  2. Copy it to your Vita via FTP/USB into your tai 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 “ux0:tai/noavls.skprx” or “ur0:tai/noavls.skprx” depending on where you store your taiHEN files.
  4. Reboot your Vita and enjoy!

If you have any issues report them to SilicaAndPina or dots-tb on the GitHub link below. SilicaAndPina, I hear you say? Don’t worry, this won’t format your Vita memory card (or ux0 partition) or potentially brick your Vita. You may look at the source code as it’s open source and compile the skprx yourself if you’re still skeptic. The developer/RE guy is @dots-tb and the project manager is SilicaAndPina.
