Q: When I plug my mini into a tv or arcade machine I have no sound or its coming from the mini itself.
A: This means the incorrect setting is selected under audio. By default these are set up for TV and are usually plug and play with most threw the display cable. If this is not the case then see the below
Go to main menu -> settings -> and under settings there are 2 audio settings that will show drivers. On the 1sst audio setting select the one below auto then go to the 2nd autio setting and work your way down the list. You have to go back 1 screen to get audio. If you go down the entire list and no sound go back to the 1st audio and go to the 2nd option then all the way down the list again on the 2nd. Its painful but the only way to figure out the correct combo.
