If I remove dtparam=audio=on in the config.txt it is automatically re-added after a reboot. Only commenting it out helps. But then I cannot access amixer, alsamixer etc anymore. And no soundcard at all is loaded
@substring
Take your time, I am not playing fulltime, have a rescue from march and also some other cats to whip... 
@Dragu if you still have your march image, can you check lsmod if a specific module is loaded ? I'll check the differences on audio between april and march (and there are many)
It had become a bit complicated for me... I leave it to you professionals 
Ok with Dragu i'm not in a hurry so take time
Could you just let me know if you find something that work it out?
Thank you
@Substring
If you tell me how to make screenshot, there is a lot. there are 6 snd_soc modules loaded snd_soc_hifiberry_dacplus and snd_soc_hifiberry_dac snd_soc_pcm512x_ic2 snd_soc_bcm2835_i2s snd_soc_pcm512x snd_soc_core
thats it for the march version.
In the 4.1 Stable in my configuration not one snd_soc is loaded.
@dragu just use raspi2png and the screenshots are saved in your shared folder
@lackyluuk
thanks.
@dragu I have also a problem with hifiberry dacplus. It worked very well with recalbox 4.0.2 but since the maj 4.1 no sound anymore....
But i have this:
boot$ cat /proc/asound/cards
0 [sndrpihifiberry]: snd_rpi_hifiber - snd_rpi_hifiberry_dacplus
snd_rpi_hifiberry_dacplus
Strange?
Thanks for your help!
@monsieurlefou What Raspberry do you use?
how does your etc/modules.conflook like? Do you have any other modules loaded than the internal sound card (bcm2835)? Or did you remove the internal one?
It seems that your card is loaded.
Hi and thanks for your help!
My PI is a PI3
My etc/modules.conf looks alike:
snd_bcm2835
uinput
usbhid
I don't remove anything
@monsieurlefou It's the same as for me. According to Hifiberry it does not matter if the soundcard is not in modules.conf when the dtoverlay=hifiberry_dacplus is set and the dtparam=audio=on is removed from config.txt. But I don't know exactly how it works in recalbox
My config.txt seems ok, dtoverlay=hifiberry_dacplus and dtparam=audio=on removed.
The command amixer returns this (it seems the voulume is set to 0, isn't it?):

Thanks for your help
@monsieurlefou You should leave dtoverlay=hifiberry-dacplus in your config.txt
I confirm that dtoverlay=hifiberry-dacplus is in my config.txt.
Just dtparam=audio=on removed
I don't change anything since the maj 4.0.2 => 4.1
Thanks
Looking at dragu's screenshot, there are 3 kernel modules that are loaded along with the hifiberry.
What also happened with 4.0.x -> 4.1 is a kernel b*mp from 4.1 to 4.4. That's the only lead I have for now + quite some changes regarding audio volumes (because of that DARN x86 version)
Hi, i progress
I reinstall from 0 recalbox 4.1.
I modify config.txt by adding dtoverlay=hifiberry-dacplus and comment (#)dtparam=audio=on.
No sound with emulastation but sound is come back under kodi.
Any idea?
thanks a lot
I don't understand.
After trying change audio settings in the audio recalbox menu to auto, to hifiberry, to auto (hacking the audio setting...), the sound is appears wihout i can understand what was the matter.....
Strange, something wrong but i cannot identify the problem.
Excuse my poor english...
@monsieurlefou that sounds really strange 
do you have the soundcard available in the sound settings in ES? For me it does not show up 
You want to say that you modified recalbox.conf
# ------------ C - Audio ------------ # ## Set the audio device (auto, hdmi, jack) audio.device=auto ## Set system volume (0..100) audio.volume=0 ## Enable or disable system sounds in ES (0,1) audio.bgmusic=0
into
# ------------ C - Audio ------------ # ## Set the audio device (auto, hdmi, jack, hifiberry) audio.device=hifiberry ## Set system volume (0..100) audio.volume=0 ## Enable or disable system sounds in ES (0,1) audio.bgmusic=0
?
Yes i have hifiberry dacplus soundcard in the sound settings in ES.
After reboot sound starts only after manipulate joystick to navigate in menu (controler xin mo). If i don't touch controler no music (??)
I'm not sure (sorry) but I remember that i have already the card in the sound settings BEFORE modify the file config.txt (it surprises me) but sounds doesn't work.
On my another pi3 with same recalbox without sound card sound start on splash screen on boot (?)
X-files???
@dragu I have also a problem with hifiberry dacplus. It worked very well with recalbox 4.0.2 but since the maj 4.1 no sound anymore....
But i have this:
boot$ cat /proc/asound/cards
0 [sndrpihifiberry]: snd_rpi_hifiber - snd_rpi_hifiberry_dacplus
snd_rpi_hifiberry_dacplus
Strange?
Thanks for your help!
