No more sound after installing v. 4.1 in recalbox

[lackyluuk]

@Dragu Great! Can you please explain what & how you did this? I still don't get it how to change the overlay

[Dragu]

@lackyluuk
I just download the overlay : hifiberry-dacplus.dtbo from the github after @Substring told about. Just this unique file and replaced the old one in the 4.1stable overlays. Size 1436 against 1693.

[Dragu]

The version from kernel 4.9.11 the last in build was the not working version. The actuel working is from 4.4.
Bulls**t that this company dont offer very simple download from their website. Time to shake them.

@Dragu Thanks for the guide. I replaced the file but dmesg shows me this:

@lackyluuk

After the Alpenjodler homepage, the -517 error is not important.
Important is just this one

 2.171884] snd-rpi-hifiberry-dacplus soc:sound: pcm512x-hifi <-> 3f203000.i2s mapping ok

Now, if you have not this line in dmesg, things worsen
Perhaps an option to flash the card, as they offer this.
Just, also full loss possible with such company.

I just looked my version is HW 2.0

[Dragu]

@Substring
@lackyluuk

I have also now the card appearing as choice in the ES soundmenu

But, still one problem.
If I switch to the existing share folder on INTENSO SSD, the sound disappear some trace perhaps in the background with alot of noise. @Substring , I am sure you know the answer.

[lackyluuk]

@Dragu i will try this and report then
Didn't know that hifiberry is a swiss company..i should blame them to put my country to a bad light, lol
ps. fondue is better

[Substring]

@dragu still on a pi3 ?

[Dragu]

@Substring
Yes, I just have running big transfert backup from my bartop share folders to the server.

[Substring]

@dragu does dmesg show anything ?

[Dragu]

@Substring
Yes, driver seems ok.

  2.142276] snd-rpi-hifiberry-dacplus soc:sound: pcm512x-hifi <-> 3f203000.i2s mapping ok

I suppose I have an error in recalbox.conf. I will compare both.

[Dragu]

@Substring
I just compared recalbox.conf 4.1stable from origin to my share recalbox.conf. Nothing that could cut off sound.

[Dragu]

@Substring
@lackyluuk

This becomes totaly crazy now.
To resume :

1. Before today I used version 4.1u (march) with my shared files on INTENSO Disk.------> Sound working, Bluetooth + Wlan also.
2. The link from github with older overlays and hifiberry-dacplus.dtbo makes actual version 4.1stable functional with working sound.
   To remember, this driver is exactly the same from 4.1u (march) version.
3. As long as I use internal storage (with internal share), sound working,
   but after selecting Intenso and using my existing share folders, sound is dead again. Ok, not completely dead because you hear some trace of sound, the card exist, the driver is loaded, the same as on the internal share, but no sound.
   If I switch in ES system back to internal storage, sound comes back again.
   Crazy, or ?

[Substring]

@dragu you probably have a ~/configs/asound.state on your SSD that you should remove + set the DAC in ES + fool around with TERM=xterm alsamixer to raise volumes

[Dragu]

@Substring
TERM=xterm alsamixer was exactly the solution, now I am arrived on 4.1 stable and thanks alot.
I put volume on 100%, as anyway I have volume regulation on amplifier.

[lackyluuk]

@Dragu great that it works fine for you now
I still don't know what to do else..not even the test image of hifiberry detected my DAC+. Thats weird.

Since recalbox is detecting my card i think its not dead..

@Substring Does it make sense to start from scratch, with a clean installed version?

[Substring]

@lackyluuk which hat do you have ? same as me or Dragu ?

[lackyluuk]

@substring I have DAC+ HW 1.0 with RCA connectors soldered

[Substring]

@lackyluuk ok mine is rev 2.6
So, step by step :

• does the module appear in ES as a sound output ?
• have you tried doing like dragu (get an old dtbo) ?

[lackyluuk]

@Substring

• No, I only have Auto, Jack and HDMI as sound outputs
• Yes, I tried the same .dtb as Dragu. No luck.

As you can see some posts before, I am somehow missing the "i2c mapping ok" line in the dmesg output
