I realize this probably gets asked a lot but I have been through some of the steps outlined on the web and am still having trouble getting sound.

I installed Retropie a few days ago, NES, SNES, Genesis working great, still ironing out the details on PSX / Neo Geo (Haven’t had time to look at the BIOS solutions out there yet). I have a Retropie 2 and installed the Beta 3.0 version. Built from an SD image, SNES gamepad, keyboard, mouse, and USB plugged in. Games on the NES, SNES, Genesis emulate fine, however, I get no sound. I am connecting through an hdmi monitor.

I followed the steps here

http://elinux.org/R-Pi_Troubleshooting#Sound

but didn’t receive any luck. The only thing I can think of is that I am rebooting (sudo reboot) afterchanging the settings. I have tried returning directly to the emulationstation screen using startx, but my pi freezes on a white screen when I try this.

Any ideas? Thanks for any help you could provide, as you might tell, I have no programming experience prior to getting one of these.

You dont use startx to load emulationstation you just type emulationstation.

you need to reboot if adjusting config.txt, but I can’t advise further other than what is on that page and other threads on the forum with ideas. usuaully hdmi_drive sorts it if using dmt mode and you want sound over hdmi.

Post your config.txt

from the /boot/config.txt file

#hdmi_safe=1
#disable_overscan=1

Overscans equal to 16

#framebuffer_width=1280
#framebuffer_height=720
#hdmi_force_hotplug=1
#hdmi_group=1
#hdmi_mode=1
#hdmi_drive=2
#config_hdmi_boost=4
#sdtv_mode=2

Is this sufficient? Thanks!

Fixed it. I saw this on another forum. You can’t just edit the hdmi_drive=2 within the pre-existing text, you have to add an additional line at the bottom. Write the text to the configuration file, reboot, and my sound worked.
