No more sound after installing v. 4.1 in recalbox

I have also the issue with my hifiberry DAC+ not working with 4.1 stable.
Just for history, I was having the same problem with 4.1 unstable from april and switched back to 4.1 unstable from march, where the sound was working. Issue that I didnt followed. So it seems to me that something important changed between this 2 versions that was important for the DAC story.
What I changed so far on 4.1 stable (just today jumped in )

/boot/config.sys
comment out
#dtparam=audio=on
 
and put missing section
 
# uncomment for hifiberry
dtoverlay=hifiberry-dacplus
 
/etc/asound.conf create
 
pcm.!default {
type hw card 0
}
ctl.!default {
type hw card 0
}
 
etc/modules.conf
comment out
 
# snd_bcm2835
uinput
usbhid

for the moment, silence is golden.....

There is a very simple way to find out if the hifiberry-dacplus card is adressed.
On the board is a green led, when the card is in contact with a driver, it is lit. When it has no connection with software, is dark.
I changed again the cards and on 4.1 stable, led is not on. With my unstable from march, led and sound.

@dragu so is it possible to get back and reinstall 4.1 from march? maybe it's one of the solutions for my issue

[Dragu]

@benj008
I think, they should have a chance to look into this.
I have the system on another card, so easy for me to change, till they find a solution.
But if you have no image anymore from build 11603320, I have no idea.

[benj008]

@dragu thanks, i was careless, i didn't have a backup of previous 4.0.1

[Dragu]

@benj008
build 11603320 is an 4.1 unstable version, that I use (for me very stable, never had a problem).
I have still the image, but if I link it here, I will be in death row.

I have just installed 4.1 and my HifiBerry DAC+ is not working at all. In the settings I can only choose between AUTO, JACK and HDMI.

The dtoverlay in /boot/conig.txt is still dtoverlay=hifiberry-dacplus and the green LED on the card is on.
But somehow in alsamixer the card is not showing up. The only soundcard is the internal.

With cat /proc/asound/cards i get the following:

0 [ALSA           ]: bcm2835 - bcm2835 ALSA
                     bcm2835 ALSA

If I remove this driver I cannot access alsa or amixer anymore

Still try to figure out some other ways to check the soundcard implementation...

[benj008]

same for me..

[Dragu]

In build 15156473 the problem was appearing for me.

@benj008 @lackyluuk @Dragu The only things that changed regarding sound are how the volumes are set/forced at boot, so I have an idea where to look BUT as I can't test by myself, I need you guyz.
So first remount / as read-write : mount -o remount, rw / then edit /recalbox/scripts/recalbox-configure.sh and comment line 409 by adding a # at the start of it and report back If it worked, remove the #, and set the volume to 100% in ES, reboot and report back.

[benj008]

@substring salut
Tipping /recalbox/scripts/recalbox-configure.sh path in putty seems to bring me to an empty file

[lackyluuk]

@Substring I will test it tonight when I am home. Thanks for the approach!

[Dragu]

@Substring
You sleep sometimes ?
The file name is in my installation recalbox-config.sh, I think you mean the same.
I made the comment out, it had no effect. I also changed in ES the sound to 100%. But the animal put it back directly to 0%, no way.

I have some other issues with 4.1s, dont want to kill you.

[Substring]

@dragu I guess I spend about 4 to 6h a day on support for 4.1 since Friday, and it's becoming exhausting ... So many people who just can't read or report false bugs ... Have to find the truth in all forum topics

But the hifiberry IS a real regression bug that sadly I can't test at home

Now can you make that line 409 look like :

for param in `amixer controls | cut -d ',' -f 1` ; do recallog "Setting volume for $param" ; amixer -q cset ${param} 100% ; done

reboot, and report ?

[Dragu]

@Substring

No, it has no effect. In ES the sound level is put back to 0% after leaving the sound menu.
But in my beloved version from march, this is the same, anyway as the volume for this card is not regulable and always at max.
I see the problem from the driver side, the hifiberry driver is not loaded. If you have the tools to run a compare between versions. If you compare build 11603320 with the stable release, somewhere shoud be the answer, I think.

[benj008]

@substring same for me the 409 line looks line the one you propose already and even with the # changes, no sound again.
But my ES seems to save volume after reboot or leavong dound menu unlike dragu..

[Substring]

@dragu said in No more sound after installing v. 4.1 in recalbox:

11603320

ok that's the runner ID.

Have you followed https://support.hifiberry.com/hc/en-us/articles/205377651-Configuring-Linux-4-x-or-higher ? looks like it's not "compatible" with our default config.txt

[Dragu]

@Substring
Yes, the modifications in the config.txt are made this way. Would also be interesting if aplay was in the package.

[Substring]

@dragu aplay is not on the pi, but aplay is not useful in that case.

Try this :

cat > ~/.asoundrc << EOF
pcm.!default  {
 type hw card 0
}
ctl.!default {
 type hw card 0
}
EOF

reboot, report

[Dragu]

@Substring
No change.
But I have no directory /proc/asound/ as lackyluuk has.
