So I've got the pi w 2 working with the pi2-3 weekly build.
I changed the config using the retroflag patch and added in the audio and dpi24 dts overlays. But am now getting the above errors and no audio. However video works perfectly.
Anyone got any ideas? It's not to do with pulseaudio is it? As I just checked that's not installed

I'm no expert but I think support is needed for the new firmware released by the Raspberry Pi Foundation for the Zero 2 W (https://github.com/raspberrypi/firmware/blob/master/boot/bcm2710-rpi-zero-2.dtb).

Is the sound working without the patches from RetroFlag ? Post your
config.txt. -
@mitu here's the config for the patch:-

Obviously doesn't give any video or audio as the pi isn't connected by hdmi but through the gpio pins. But ssh into the pi is giving me the same audio error as above.

What's the output of:
aplay -l amixerI see in the config that the on-board audio is not disabled, but the audio is also configured over the GPIO pins with the
pwm-2chanandpwm-audio-pi-zerooverlays, which might not work 100% on the new model. -

I spent a good amount of time now on trying to figure out what is the problem. I don't think it's the overlays, since when you use a video splash screen, it gives out sound. It's probable that the
splashscreenpackage usespulseaudiowhile everything RetroArch related doesn't. -

No, it's not the splashscreen. The errors come from ES, which is not related to the splashscreen at all.

Do you have an
$HOME/.asoundrcor/etc/asound.confgfile ? -
@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?

@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? -

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
