It's because volume control is not plug and play.

Start, select, vol+, and vol- are routed to GPIO pins and can be configured to do anything you like. The VOL+ and VOL- buttons can issue keyboard presses to the OS (using retrogame), and the retroarch configuration file can be modified to allow SEL + VOL UP or SEL + VOL DOWN to change the volume. It's not exactly a simple process, which is why I don't advertise the volume buttons yet. I'll probably have to put a guide together for you guys that want volume buttons.

This is the file on the Retroarch github so you can get a look at it. There are people on the retropie and sudomod forums that have already done the configuration, so you can probably follow their process. Look for anyone that uses the keyboard to adjust the volume.

this is what is currently only missing on mine. Checked the GPIO and they had no 3.3v but I see they are configured in the files you added to the project. I  haven't had much time to look into it but definitely volume control is imho a must have. 

thanks for the info!

Hello everybody

I think I'm too stupid to get that with the keys Home Vol + and Vol - just do not go, maybe you have a ready config for me?

sorry for my bad English

Only the volume buttons are wired and configured, the Home button is not. I'll write some code and post it for you guys once I'm able.
