Here is a new Gmu Beta release for the Dingoo A320. This release comes with some major improvements and bugfixes including:

» Backlight power-off is now functional on the Dingoo (backlight will be turned off when the hold mode is enabled as well as after a configurable amount of time without pressing a button)
» FLAC decoder now comes with meta data tag support
» MP3 decoder does no longer crash Gmu with broken/invalid files

Gmu is highly configurable. It is always worth it to have a look at the README.txt file. Especially if you are having trouble running Gmu, make sure you have read the “Installation” section of the README.txt file.
