[SOLVED] Hi-Berry DAC+ - Failed to open Alsa default

[no_ears]

Hi, 
tl;dr- new Hi-Berry Dac+ has arrived, but I'm getting "Failed to open "ALSA Default" (alsa); Failed to open ALSA device "_audioout": Invalid argument" error. 

As detailed above, raspberry pi3, hi-berry dac+ and the latest (litterally updated today) version of Moode. When I try to play anything I get the above message.

In settings, I've scanned for the audio devices and the software sees it. 

I also did a search on this forum and found a post saying to change i2s setting to none. tried that, and selecting the device too - no joy. there was also a post saying to change the MPD driver, but i couldnt find that in the settings, maybe it was an older version?

followed the hiberry guide to install drivers via Git - that hasnt worked either. (https://www.hifiberry.com/docs/software/...ux-kernel/)

bit stuck, im undoubtedly doing something silly, but i don't know what else to try.  I've attached some screen shots for further information

Could you please suggest further steps i could try? thanks in advance...

Reboot and then post the entire contents of the startup log so people can better understand your configuration.

The log can be viewed via the SSH command moodeutl -l or downloaded via the Logs section in System Config, or via Menu, System info from any of the Config screens. The startup log will be at the end of System info output.

Thanks Tim for the quick reply and suggestion - i hadnt thought to check logs (duh)

I've reviewd and found possible area for review: 

20250701 234558 worker: Audio device:  0i HDMI 1
20250701 234558 worker: ALSA card:     has not been reassigned
20250701 234600 worker: MPD config:    updated (iec958 device)
20250701 234600 worker: ALSA output:   HDMI


So I went in to the output setting in the GUI and it had indeed reverted to the hdmi output (and played fine) when I changed back to the hi-fi berry, same issue. 

I rebooted at lunch time, and the card was recognised but the logs showed the same as above, and the error message

This log entry is missing the kernel version number. Very odd.

Code:

20250702 090308 worker: Linux Kernel:  33 64-bit

[no_ears]

Solved: I rememberd this afternoon i had programmed pin 3 for a power on/off. in the hiberry documentation it says it uses pin 3 so i commented it out and its now working.

so i'll leave this here in case it helps anyone else. i'll inevitably have to raise a new cry for help when i cant make the power button work!

I dont really know what that would mean. I originally created the SDCard using the pi imager so presumably the linux came from there? I did some kernal update as instructed by the Hiberry github..
The issue with the DAC is resolved, but if its worth reflashing a SD card i can do so..

[Tim Curtis]

Yes, definitely re-flash to get the official kernel used in our images :-)

will do! thank you so much for the help
