No sound retroflag gpi case with pi zero w 2 (Solved)

@mitu the files aren't there. I guess need to install something?

@retropieuser555 Is this before adding the RetroFlag's drivers/scripts or after ?
Normally, on a clean install, none of the files are present. Sinceaplaydoesn't list any sound cards, the error you get in ES is normal, but I'm wondering if the GPIO connection on the RetroFlag case don't need additional configuration.The splashscreen uses
omxplayerto play sound, which bypasses any ALSA configuration, but EmulationStation (and most of the emulators) need a working ALSA config.I always thought the
config.txtis universal to the raspberry pi itself, rather than the OS etc?No, it's specific to the RPI bootloader, but there are other boot methods (U-Boot perhaps) that don't use the file.
-
@mitu This is after adding the config.txt and overlays that the retroflag gpi. I can test it with the stock config.txt and original dpi24 overlay if that helps?

After further testing, I can't get either
alsanorpulseto work as sound drivers.
alsadoesn't find any sound card, thus is not able to play.
pulsecan find the virtual sound card, but cannot output sound for some reason.@mitu you are right, sound plays just fine with
omxplayer.I don't think it's the GPi cases' fault, but rather the drivers not able to play over GPIOs?

You can do that, but - at best - you'll get sound only on the HDMI port, which is not what you want. But this configuration should get rid of the ALSA error and you'd have at least one card listed by
aplay. -
@mitu you think it's worth a shot trying to manually create the
asound.conffile? -

@philcomm okay that's interesting, I didn't notice that. I just tested a splashscreen with audio and it did play the sound for me too, no errors.
I tested out the beta of the recalbox image they have and it played audio as well, so it does seem workable somehow, there config file is quite different though, I always thought the config.txt is universal to the raspberry pi itself, rather than the OS etc?
Do you still have that image? My download is super slow, it takes another two hours to finish (around 60kb/s)
-
@philcomm the recalbox beta? Yeah I've got it here, should I post their config or something from it?
-
@retropieuser555 I wonder if there is any difference in the
/boot/config.txtfile compared to RetroPie. Also, is the md5 hash of/boot/overlays/pwm-audio-pi-zero.dtbothe same? -
@philcomm Here's there config file:-

Any ideas how they got this working? Guess can go onto their forum and ask them

@retropieuser555 Does the
/etc/asound.conffile exists? If yes, what's the content? -
pcm.monocard{ slave.pcm "hw:0" slave.channels 2 type route ttable { # Copy both input channels to output channel 1 (Right). 0.1 1 1.1 1 # Copy both input channels to output channel 0 (Left). 0.0 1 1.0 1 } } pcm.!default monocardThing is though, I don't know a great deal about recalbox, but it's not built on raspbian? Think if I used this in the retropie build it'll work?

I will have to try later if that works

Hi, I have been struggling with the same issue, and have managed to solve it.
The issue is that by default the latest version of Raspbian disables the audio if nothing is connected to HDMI.
Use this one line entry in config.txt to fix it:
dtoverlay=audremap,pins_18_19,enable_jack=onYou don't need the pwm-audio-pi-zero.dtbo file and you can remove all the custom audio entries from Retroflag's config.txt and use this one line instead. (leave all the entries for the LCD in obviously).
The custom asound.conf file in recalbox is used to downmix stereo audio to mono, as the built in speaker on the GPi only outputs the right channel.
-
@slime1982 Hey that's great news can you post your config.txt file please? I think I'm deleting the wrong lines out
-
Start with the stock config.txt and add this at the end:
#Pi Zero 2 W GPi Config dtoverlay=audremap,pins_18_19,enable_jack=on display_rotate=1 dtoverlay=dpi24 overscan_left=0 overscan_right=0 overscan_top=0 overscan_bottom=0 framebuffer_width=320 framebuffer_height=240 enable_dpi_lcd=1 display_default_lcd=1 dpi_group=2 dpi_mode=87 dpi_output_format=0x6016 #hdmi_timings=320 0 28 18 28 480 0 2 2 4 0 0 0 60 0 32000000 6 hdmi_timings=240 1 38 10 20 320 1 20 4 4 0 0 0 60 0 6400000 1you still need Retroflag's dpi24.dtbo, but you don't need to copy the pwm audio overlay file.
The custom asound.conf file doesn't work, I suspect because the sound device is now referred to as headphones instead of pcm, but I'm working on it now.
Also, go into raspi-config, system options and in audio select 'headphones'. it should be the only option, but select it to ensure it is the default device.

@slime1982 Are you an angel? insert Anakin Star Wars GIF

Ha! no, just very determined!
However, it's not quite right yet. On testing with headphones, the L and R channels are swapped, so I've changed the line to
dtoverlay=audremap,pins_18_19,swap_lrnote that enable_jack=on does not appear to be necessary .
Still working on fixing asound.conf so both channels play through the GPi's speaker. I'll reply with an update when I figure it out.
-
@slime1982 Almost there!
You're using their dpi25 overlay right? I'm getting some lines across the screen (but audio does work!)
MD5 (/Volumes/boot/overlays/dpi24.dtbo) = 55906663a9752f0588b74c407437dc16Is that your md5 hash for your dpi24?
-
I'll try to make a PR to RetroFlag for these changes. I hope they have a repo for their GPi Patch
