HDMI no sound Bug : need help !

[sengui79]

hello retropie friends !

i’ve got a problem with the hdmi.
i am on a RASP pi b+ and on some tv there is no sound.

the power supply is a good one (with 2000mA) and the HDMI is the same for all tested TV.

on my tvs (samsung and Panasonic) and my computer (iiama) i’ve got the sound by HDMI but when i try on (for exemple) a sony bravia, LG no sound HDMI.

I try all the modifications on the TV but no results (for in formation the raspberry audio output works)…

Please HELP ME !!!!!!

Thanks @insecurespike i’ll try this solution !!!

That should work. With my computer’s monitor with HDMI all worked immediately also, with pi b and b+.

When connecting to my Samsung HD tv, and the pi b everything was finetoo. With the pi b+ there also wasn’t any sound. Setting hdmi_drive=2 solved the issue immediately.

Some HDMI equipment interpretates the incoming signals a bit different than others. This setting solves the issue probably right away.

Works on my end on a Sony Bravia and a visio.

On your bravia you add the hdmi_drive=2 line ? Because i dont saw any differences :(
Other ideas ?

You did save the file after the change?
Sounds dumb but I did edit mine in the past with sudo nano, but forgot to save with ctrl-x I thought.

I found an old tutorial on my computer. From what I remember I did try this in the past on a spare sd card just to test, and from there things worked out well. Maybe you can try this aswell, just to be sure where to begin searching the base of the problem.

Maybe not, but I’ll post it anyway, hope it can help you a bit too.

[Code]
Instuctions for others who may be experiencing the same issue with a TV and the Raspberry Pi:

1. Install a fresh image

2. start-up the Raspberry Pi and let it set itself up (normal set-up)

3. After you have gone through normal set-up:

a. Log-in as a normal user (debian image: pi)

b. Type the command: “sudo nano /boot/config.txt ”

c. Press enter

d. Type in: “hdmi_drive=2 ” [exactly as it is here]

e. Then press crtl + o

f. Press Enter

g. then press crtl + x

4. Restart using the command: ” sudo shutdown -r now ”

Yep, I have that line in my config.txt. Actually, I seem to remember that config.txt had that line already, I just uncommented it.

hdmi_force_edid_audio=1

worked for me

I had the same issue. ended up doing this.

RETROPIE BOOT CONFIG

sudo nano /boot/config.txt
uncomment hdmi drive 2

[postman87]

Hi all,

I’m having this same exact problem with retropie 3.0 beta.
I tried this solution but somewhere in the config.txt there allready is a line that says hdmi_drive=2 . I’m not sure what I’m doing wrong here, so help would be appreciated. My config.txt looks like this. I did not edit anything, it came like this after installing 3.0 beta.

# uncomment if you get no picture on HDMI for a default “safe” mode
#hdmi_safe=1

# uncomment this if your display

has a black border of unused pixels visible
# and your display can output without overscan
#disable_overscan=1

#

uncomment the following to adjust overscan. Use positive numbers if console
# goes off screen, and negative if

there is too much border
#overscan_left=16
#overscan_right=16
#overscan_top=16
#overscan_bottom=16

# uncomment to force

a console size. By default it will be display’s size minus
# overscan.
#framebuffer_width=1280
#framebuffer_height=720

# uncomment if hdmi display is not detected and composite is being output
#hdmi_force_hotplug=1

# uncomment to force a specific HDMI mode (this will force VGA)
#hdmi_group=1
#hdmi_mode=1

#

uncomment to force a HDMI mode rather than DVI. This can make audio work in
# DMT (computer monitor) modes
#hdmi_drive=2

# uncomment to increase signal to HDMI, if you have interference, blanking, or
# no display
#config_hdmi_boost=4

# uncomment for composite PAL
#sdtv_mode=2

# for more options see

thanks in advance!

hey just edit the file by deleting/u commenting the # in front of hdmi_drive=2 then save exit and reboot

[postman87]

Ok nevermind my noobishnes… Forgot to uncomment. works perfectly now!

So after letting the Raspberry Pi sit with no power for about 5 mins or more, i plugged everything back in and it booted fine with sound. Anytime i did a Sudo Reboot or a sudo shotdown -h now…the next time i turned it on, the picture seemed zoomed in, and no audio came out.

Make sure you go to the config and set HDMI as your primary, take all options off of auto. But unplugging and walking away for a bit, fixed my issue. It would break again when i left emulation station or tried to go back in anytime within 10mins of there being power. Its lame.
