Recently, it seems that Team CBPS is on a roll when it comes to releasing plugins for the PlayStation Vita, first with the LOLITA500/444 plugins last week and now with Volume_Profile by Marburg (cuevavirus).
Volume_Profile provides a feature that you probably use without even knowing it as its available on iOS and other platforms (GIF can be seen in the GitHub link below)

This quality-of-life plugin, which is based on a pretty simple concept, automatically saves and switches volume levels whenever you connect or disconnect your headphones. In other words, the functionality of the plugin can be described as follows:

  • If your PSVita is currently emitting sound from its speakers (i.e. no headphones are connected) and then you connect headphones, this plugin takes note of your current volume level and changes the volume level to the same level you had when you last used headphones
    • As a result, youll avoid getting very loud sound blasted into your ears immediately when you connect headphones

  • On the other hand, if your PSVita currently has headphones connected and you disconnect them, the plugin takes note of your current volume level and proceeds to change the volume level to the same level you had when you were last using the speakers

When it comes to installation, you can get volume_profile on your system by downloading it from the link below (in SUPRX form, as its a user-mode plugin) and putting it under the *main section of your taiHEN config.txt. The plugin supports FW 3.60 and 3.65-3.73 and AVLS functions normally when using this plugin.
To read more about volume_profile and download it, check out its thread on Team CBPS forums or its GitHub page.
