No more sound after installing v. 4.1 in recalbox

[Dragu]

@Substring
Ok, I will proceed again with fresh card.

[Substring]

just updated my post to add a chmod

[Dragu]

@Substring
This time, seems it was working. But still no sound, just for the feedback.
Like it was a fresh install, just need some time to configurate the network.
And for your info, I also did the hifiberry line in config.txt, and comment dtparam.

[Substring]

@dragu So this is definitely not a recalbox config itself problem, but a kernel modules loading ...

You should try to manually modprobe all the missing modules from your previous screenshot. What I don't understand is why the kernel doesn't detect your hifiberry and load the drivers accordingly ...

I am just a simple man...I am not inside this stuff.

Concerning my config.txt

[Dragu]

@Substring
To compare, I shot the screen lsmod from march 4.1u
Thanks anyway for your help and not urgent.

@Dragu @Substring I will try it out as well with the old config.sh and report as soon as I am home.

[Substring]

@dragu I prefer support archives
Hifiberry doc suggests to add dtdebug=1 in config.txt to eventually debug. could you add it ? (see "Device not recognised?" at https://www.hifiberry.com/build/documentation/configuring-linux-3-18-x/) and make a support archive ? I'd like to check what dmesg reports

[lackyluuk]

@Substring https://file.ac/drgmKFzTWo0/

• Added your "old" config.sh
• Commented out dtparam=audio=on
• Added dtoverlay=hifiberry-dacplus
• Added dtdebug=1

Not even the green indication light on the hifiberry dacplus is on

Anything else I can test?

[Substring]

@lackyluuk i need the output of dmesg since dtdebu=1 should make device trees verbose. You can make a support archive, that would be even better

[lackyluuk]

@Substring I have attached one above

[lackyluuk]

@Substring Did you already have time to have a look at the support archive?

[Substring]

@lackyluuk sorry, this got out of my mind ...

Well, nope, nothing special, as if the pi wouldn't load the overlay or god knows what

[Dragu]

@Substring
Yes, I understand,
the x(86) compatibility is a killer.

[lackyluuk]

@Substring okay, thank you for checking. I ran out of ideas Just let me know when you have some new ideas to check
Thanks mate

[Substring]

@dragu someone's making fun at me here, uh ?

@lackyluuk the only thing i understand is that kernel modules aren't loaded. So i guess the device is not found by the kernel.

@Dragu do you think you can check in your march version if dmesg finds the hifiberry ?

[Dragu]

@Substring
Hi,
Yes I see it on the list. How can I send you the result of dmesg ?

[lackyluuk]

@dragu you can create a support file. The easiest way is to let it be created by the recalbox manager. There you also get directly a link to the file which you can share

[Dragu]

@lackyluuk
@Substring
Simple, thanks. Hope that everything inside.

@dragu Ok so in that case, we do see

[    2.938674] snd-rpi-hifiberry-dacplus soc:sound: ASoC: CODEC DAI pcm512x-hifi not registered
[    2.938691] snd-rpi-hifiberry-dacplus soc:sound: snd_soc_register_card() failed: -517
[    3.012972] snd-rpi-hifiberry-dacplus soc:sound: pcm512x-hifi <-> 3f203000.i2s mapping ok

So it really looks like a device detection problem, which can only occur at boot ...
