Batocera Pi2 - sound from jack.

changging this in the GUI doesn't seem to work.

SSH into the pi and enter the command below! all working !

amixer cset numid=3 1

Editing the /boot partition while Batocera is running

mount -o remount,rw /boot



Must have UI settings

these just stop all the shitty menu transitions when coming in and out of games!

mainmenu

system settings

developer

hide when running a game-(switch right)

&

mainmenu

ui settings

game launch transition-instant

Another that is awesome is the " lunch game on startup " boots directly into a game.

Pick the game you want then edit advanced game options and the option is the last one on the list!!!

Fix Video Snap Sound


If you have sound on EmulationStation, and in the emulators, but you can't hear the sound of the video snapshots, here are several steps that may help you:

  1. First, make sure you have enabled video snaps sounds in the menu SOUNDS SETTINGS → ENABLE VIDEO AUDIO

  2. Then, you can try to connect to Batocera through SSH and enter the following command:

wget -O /userdata/system/.asoundrc https://www.batocera.org/users/lbrpdx/asoundrc

This command will create an alsa config file as /userdata/system/.asoundrc. It should fix your video snap sounds for most SBC like Odroid Go Advance, but maybe not on a PC.

On a PC, depending on your hardware configuration, your GPU and audio chipset, it might be trickier to get it working.

First, through SSH, get the list of audio outputs with the command aplay -l. In my setup, I get:

# aplay -l

**** List of PLAYBACK Hardware Devices ****

card 0: PCH [HDA Intel PCH], device 0: ALC255 Analog [ALC255 Analog]

Subdevices: 1/1

Subdevice #0: subdevice #0

card 0: PCH [HDA Intel PCH], device 3: HDMI 0 [HDMI 0]

Subdevices: 0/1

Subdevice #0: subdevice #0

card 0: PCH [HDA Intel PCH], device 7: HDMI 1 [HDMI 1]

Subdevices: 1/1

Subdevice #0: subdevice #0

card 0: PCH [HDA Intel PCH], device 8: HDMI 2 [HDMI 2]

Subdevices: 1/1

Subdevice #0: subdevice #0

card 0: PCH [HDA Intel PCH], device 9: HDMI 3 [HDMI 3]

Subdevices: 1/1

Subdevice #0: subdevice #0

card 0: PCH [HDA Intel PCH], device 10: HDMI 4 [HDMI 4]

Subdevices: 1/1

Subdevice #0: subdevice #0

If I want to use the audio output from HDMI0, I can see that it is card 0 and device 3. So, to make audio work on my setup, I need to edit the /userdata/system/.asoundrc file and replace pcm “hw:0,0” with pcm “hw:0,3”, and then save and on reboot, it worked. This method might not work in 100% cases, but it's worth a try.

Worst case, if it doesn't work and you want to go back to the original state, just remove the file /userdata/system/.asoundrc (or \system\.asoundrc from the network share).

Screen Rotate

1.SSH into your machine (I'm assuming you now how to do this, let me know if you want more info)

Copy\Paste or Type each of the following commands and press enter

  1. cp /etc/X11/xinit/xinitrc ~/.xinitrc
    This makes a copy of like the master file and creates an editable user file

  2. nano ~/.xinitrc
    The wiki uses "Vi" to edit file, I prefer "Nano" so I have changed it for my ease of writing this.

  3. The .xinitrc should now be displayed in Nano, Scroll down using the down arrow until you get to the following section:

# rotate the screen

# xrandr -o left

# xrandr -o right

# xrandr -o inverted

  1. Delete the "#" in front of which way you want it to rotate.

  2. Press "Ctrl X" , press "y" to agree and "enter" to proceed.

Should be now back at the commandline, type "reboot" to restart your machine.

The purple Bactocera splash screen does not seem to rotate. But the next loading screen and emulation station will be rotated.
