No more sound after installing v. 4.1 in recalbox

[lackyluuk]

@Dragu Don't know if it's relevant for this, but have you created a asound.conf file?

I also noticed that if I remove the internal sound card, it is added back after every reboot into /boot/config.txt

[Dragu]

@lackyluuk
@Substring

Yes, /etc/asound.conf I created, is there that I made the modifications from
before, (cat >..) I expect it was the right place, or should this block be in /boot/config.txt ?

[Substring]

@dragu WTF ? no /proc/asound ??? i guess lackyluuk hasn't removed the dtparm=audio=on from the config.txt. But still ... I'll look at changes since March

[lackyluuk]

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

[Dragu]

@substring
Take your time, I am not playing fulltime, have a rescue from march and also some other cats to whip...

[Substring]

@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)

[benj008]

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

[Dragu]

@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.

[lackyluuk]

@dragu just use raspi2png and the screenshots are saved in your shared folder

[Dragu]

@lackyluuk
thanks.

[monsieurlefou]

@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!

[lackyluuk]

@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.

[monsieurlefou]

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

[lackyluuk]

@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

[monsieurlefou]

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

[lackyluuk]

@monsieurlefou You should leave dtoverlay=hifiberry-dacplus in your config.txt

[monsieurlefou]

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

[Substring]

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)

[monsieurlefou]

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

[monsieurlefou]

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...
