RetroFlag with CM4 no audio

G30FF

@rasp_renegade You'll need to use vi on the terminal to create the file, because starting a file with a . means it's a hidden file.

Can you reset audio settings while it's plugged into the dock?

Not sure what happened but I went to try that from the dock, but the pi would not boot "config.txt does not exist". So I ran the patch to get it back, but now I cannot run the safe shutdown script to get back to the dock.

See attacked. This keeps scrolling on the screen so I cannot even type or use up arrow to get to the command. How do I make that stop?

@rasp_renegade I have no idea what you've done here. You might have changed the permissions on the files, or otherwise broken the configuration. Check that the files in /boot are owned by the same user as the rest of the files. Worst case scenario you will need to reinstall RetroPie.

Those errors went away. I was able to set Audio to default from ES, but now I cannot connect to install the shutdown script. "404 not found" when running the command. I am able to ping 8.8.8.8 so I have internet
"wget -O - "https://raw.githubusercontent.com/RetroFlag/GPiCase2-Script/main/retropie_install_gpi2.sh" | sudo bash"

Fix one thing and another breaks. =/ I will try later since they may have issues on the website. The page loads in a browser on Windows.

Is the safe shutdown script responsible for making the display on the retroflag work? Here is the process I think I followed previously, but no luck this time.

Install the patch from https://github.com/RetroFlag/GPiCase2-Script/raw/main/GPi_Case2_patch.zip
Press F4 when docked and run the command for the script, wget -O - "https://raw.githubusercontent.com/RetroFlag/GPiCase2-Script/main/retropie_install_gpi2.sh" | sudo bash

The script installed without errors.

As far as I know, the config.txt file from the patch zip makes the screen work. And the safeshutdown script checks if the dock is used or not and then replaces the original config with either the lcd or hdmi variant.

And for me the installation of the shutdown script fixed the audio problem.

Here is what I did (using a different Pi):

Flashed the image
Manually copied the three config files to the new boot partition (/boot)
Started Retropie for the first time and configured WiFi and enabled SSH.
After an reboot, I used ssh to connect and ran the safeshutdown install command.

Then sound was working for me. I added my own way later to switch between Speaker (Mono) and Headphones (Stereo) later, which was already mentioned somewhere in here. I don't know why you're having so much trouble.

I don't know why you're having so much trouble.

If you were to read my many posts here from over the years you will find that technology hates me. LOL AND Ive been in IT for about 20 years!!!

Thanks, I will review my process and see what I missed. Frustrating when I got the display to work twice before and now nothing.

@rasp_renegade I believe it also matters if you use the dock from the beginning or not. Sadly I personally don't have the dock myself. I only had the chance to get a bundle of the Case and a CM4 a few weeks ago. But since the shutdown script does swap out the different config files, it is kinda necessary to do the initial installation without the dock. But I'm not sure about that and obviously can't test it.

I must have had the wrong patch somehow. I downloaded again and copied to the boot folder and ran from Windows and got the LCD to work again.

I booted up connected to the dock.
Went to Retropie-Audio from EmulationStation, and selected Reset to default.
Rebooted un-docked.
Returned to Retropie-Audio from EmulationStation and I still get "On-board audio disabled or not present".

I have another retroflag here that I need to return. I verified it also has the same issue. How am I supposed the configure the audio?

EctoOne

@rasp_renegade Hmm, I've only messed around with the sound options before I installed the shutdown script because it had no audio before that.

My current settings are:

Audio Card = Default
Audio Device = Speaker
Navigation and Video Sounds = Off
OMX Device = Both

@EctoOne

OMG! I reimaged and the same exact thing. Did just the basics as you suggested and in ES under RetroPie-Audio there was the message, "On board audio disabled or not present"

BUT, I played with the settings in ES and selecting Headphones, and the sound works.!!! With or without plugging in the headphones. ???? I nearly crapped my pants when I first hear audio play. LOL

I think I tried that option before I wiped it, but I guess I will never know. Thank you so much @G30FF and @EctoOne for your support.

EctoOne

@rasp_renegade Nice, now if you plan to use the build in speaker you should add that other script/file which was mentioned in this thread. Otherwise you will only have Mono sound. Although I have not heard idea how that works with the dock.

Maybe you should get the Super Nintendo version of the 240p Test Suite first to test the audio. You can get it here: https://artemiourbina.itch.io/240p-test-suite

Oh yeah. Will do. Thank you!
