No sound out of HiFi Berry DAC + with Volumio2 (2.799)

[Markinton]

same problem here: I use the RPI 7’ display on a RPI 3B+ and the Hifiberry DAC 2 HD and Volumio
and update to latest version 2.799. The Hifiberry is conflict with the RPI 7’ display and plugin version 1.1.8. The detail of the plugin notes: ‘Using this plugin is not recommended with Raspberry PI B+! Suggested, Raspberry PI 3, Odroid C1 or C2’. I have no problems with this setup and the Hifiberry Digi + pro board before the update to 2.799. When i disable the power to the display everything works. After the latest update this error ocured. Any solutions or experiences? kind regards

@Markinton:

Can you also post the log with the display connected?
I can’t, becaus after I tinkered around for a whole day yesterday I was frustrated and locked the screen away.

I have the same problem. But only if I add the touchscreen into the mix. What seems to happen then is that the card1 (HDMI) disappears from aplay -l. Volumio still tries to address card2 (hifiberry) which now is card1, giving me the ALSA error. Forcing card1 via mpd.conf will work but the mixer is then set to “undefined” so no volume control.

Removing the touchscreen and setting up the Hifiberry Dac+ will restore sound, as the HDMI returns as card1 .
Do you guys have the same problem? I see only two devices in your aplay -l -logs.

Question: Is there a way to change the order of the soundcards, so Hifiberry is 0? Or maybe could volumio recognize HDMI is missing and update the order of the cards?

This is exactly the point, enabling DSI touchscreen makes HDMI to disappear from the list and I2S DAC becomes card1

[Panos70]

I got it working. Its actually quite simple, it looks like the enumeration of output devices is not working.
Edit the /etc/mpd.conf file.
Find the audio output section
change the device “hw:1,0” - it was 2,0 before.

it worked for me.

[kilby19]

Could you write it out step by step so we can all fix the problem

Thanks

[Panos70]

I will try. Enable SSH, by going to http:\your volumio IP\dev.
click enable under ssh.
then connect to the volumio via for example Bitvise SSH (i use this one)
there is a file manager with the program so its probably the best way, find the mpd.conf file under the \etc directory and double click on it to edit, remember to save.
or using the terminal, find the directory and sudo nano mpd.conf

I hope it hepls?

[apemonkeychimp]

Works for me but no volume control possible. Mixer is set to ‘undefined’. Anything I am missing?

[Panos70]

I have mine on none, so I cannot answer that. Another thing to remember, is that the change will be overwritten if you change your output device, so its necessary to edit the file again.

[apemonkeychimp]

Thanks you. Since it’s reverting back to using the non-existent card2 after changing output, it really is a bug that might be fixed soon. I spent the whole day yesterday trying to figure this out, thinking I was just too unskilled.

[Markinton]

Got mine working, thanks for the solution!

[gvolt]

I can’t test myself ATM but maybe you can check if it helps to add

snd_bcm2835.enable_headphones=1 snd_bcm2835.enable_hdmi=1 snd_bcm2835.enable_compat_alsa=0

to /boot/cmdline.txt to get back all endpoints as different ALSA devices?

Edit: Possibly it is necessary to set snd_bcm2835.enable_compat_alsa=1 respectively to leave out snd_bcm2835.enable_compat_alsa completely if you should encounter problems choosing the default device.

[Darmur]

Sure i’ll test right now

[Darmur]

original cmdline.txt already had the option snd_bcm2835.enable_compat_alsa=0

with DSI touchscreen and snd_bcm2835.enable_headphones=1 snd_bcm2835.enable_hdmi=1 snd-bcm2835.enable_compat_alsa=0

[Darmur]

to summarize, the fix should be this:

1. remove snd-bcm2835.enable_compat_alsa=0
2. add snd_bcm2835.enable_headphones=1

with this change problem is gone, both with and without DSI touchscreen connected.

I performed this test with a RPi4 (2Gb)

please let me know if you need testing with other RPi version, I have a RPi3a and I can get back a RPi2 in the coming days

[gvolt]

Many thanks for the extensive tests.

Would be helpful to check at least on a Pi3 since the changes to Pi4 were more radical than between e.g. Pi2 and Pi3.

[Darmur]

I can confirm the trick works fine on RPi3a too

Thanks a lot!
I confirm this fix works. Raspberry Pi 3 A+ w Hifiberry AMP2 + DPI screen. Volume mixer works even after reboot.
