Hifiberry DAC2 HD not working with 3.702 on Pi 4 - mixer type UNDEFINED

Help and Support
1

Hifiberry DAC3 HD with the latest 3.702 on a Pi4 does not produce audio. I suspect the upgrade to this latest version caused this. Under Mixer Type -I get the error UNDEFINED.
If I Save (under the Mixer type) it then recognizes the Mixer type as Hardware - just no audio
I have rebooted, powered down/up all day. No luck…yet I can see the device is running - just no audio

Any ideas out there?

Thanks in advance
Ian

Thanks go to the DEV’s from Volumio.
I Only spend hours on testing :joy:

It appears there are issues with a certain Linux kernel version in combination with HifiBerry. This was not caused by Volumio.

I had to reboot…and the same problem has cropped up. Did a Factory Reset, Did the Developer upgrade…still not joy. Mixer comes up as ‘undefined’ …If I press save under the Hifiberry DAC…then it sees the DAC under mixer type

Strange, that was one of the issues with the kernel.
I ran tests on 2 devices and rebooted 20 times without issues (HifiBerry DAC2).
Just try some reboots and see if it sticks.
Also provide the output of:

cat /boot/config.txt
cat /boot/userconfig.txt

and copy it here.

After many power offs/reboots - it came alive.

volumio@volumio:~$ cat /boot/config.txt

I dont think I have a userconfig.txt file

volumio@volumio:~$ cat /boot/userconfig.txt
# Add your custom config.txt options to this file, which will be preserved during updates

first remove all, but one. There should be only one line for your DAC.

#### Volumio i2s setting below: do not alter
dtoverlay=hifiberry-dacplushd

So it looks like this:

### DO NOT EDIT THIS FILE ###
### APPLY CUSTOM PARAMETERS TO userconfig.txt ###
initramfs volumio.initrd
gpu_mem=128
gpu_mem_256=32
gpu_mem_512=32
gpu_mem_1024=128
max_usb_current=1
[pi5]
usb_max_current_enable=1
[all]
include volumioconfig.txt
include userconfig.txt
#### Volumio i2s setting below: do not alter ####
dtoverlay=hifiberry-dacplushd
