What do you mean by “register”? (the error screen?)
Thanks bye
I sent the error message and that with raspberry 4 and Hifiberry Digi2 Pro does not work while with Raspberry 3 everything is ok.
Let’s update on possible improvements, Thanks bye
I really wish I had something to recommend, I purchased the HifiBerry Digi+ Pro because I saw it in the list of supported hardware under I2S but apparently that one no longer works under Volumio version 3, at least for now. I tried to install version 2.917 which is the version it last worked but I don’t know if the image I got was corrupt or the installation is different than version 3 but it is not working for me.
I am new to Volumio and had everything working until I tried to use the HifiBerry Digi+ Pro (Which I chose because it is in the I2S list of devices) in order to use spdif coaxial out to my DAC, my hardware and software are as follows:
Raspberry Pi4 8GB
Hifi Berry Digi+ Pro
Schiit Modius DAC (which does work as a USB device with Volumio 3)
Volumio 3.251
System was working fine until I added the HifiBerry, then I got the Alsa error, I looked around the forums here and tried the fixes suggested.
I tried turning off I2S and choosing the headphone out and then rebooting the system and then turning I2S back on and selecting the HifiBerry Digi+ Pro from the list, still got the error.
I tried choosing some different HifiBerry devices from the list and also the Generic I2S device, some of those would not give the error but did not pass sound.
After all this, I did send my log, at least one post in the forums said that some I2S devices are having problems under Volumio 3 and it is hopefully being worked on.
I tried to install the last version of Volumio 2 on a different micro sd card but could not find the IP address using Fing or see the Wifi hotspot to complete the setup, either my image was bad (although it did seem to install properly twice) or there is something different about the installation process instructions that I was not able to find.
So this is where I’m at, I’ll continue to use my DAC as a USB device and hope there is and update to 3.251 that then allows me to use the HifiBerry Digi+ Pro unless someone here can suggest something I haven’t tried, thanks!
This was hurting my brain for a while and I have a solution at least for my setup.
Setup - Hifiberry Digi+ Pro with RPi 4 something like 1.4, it’s before the 1.5 that HFB say is problematic.
Symptom - power system off. Then power it on. Now ALSA troubles on pressing play.
Fix - 1. Power up and wait for system to be FULLY loaded again (note this takes a while even after webUI is accessible)
2. then go to the audio output, switch off I2S DAC and select Headphones (HDMI might work too not tried)
3. SAVE!!
4. Reboot
5. Play something even for a second. Just let the track location start progressing. This seems unnecessary but appears to help.
6. STOP the playback. Essential or it’s gonna still be screwed. From memory.
7. Back to Audio Output. I2S DAC ON again.
8. Select Digi+ Pro - there’s no Digi2 Pro as further evidence that God no longer watches over us
9. SAVE
10. Reboot.
11. A minor miracle - the thing starts to play correctly through the Digi2 Pro. Evidence that God had half an eye on and is an audiophile.
It shouldn’t be this awkward… but at least it works I suppose. Got me pretty tempted to find another hat with better quality componentry - wouldn’t have expected incompatibility with v1.5 and partial incompatibility with v1.4.
Peace out
I tried everything you said and can confirm that there is still a problem with version 1.5, I would have thought like you did that more recent hardware would be more compatible and not less. At this point, unless there is an update to the RPi 4 firmware that becomes available or Volumio can figure out a way to patch the system to work with HifiBerry, I may have no choice but to replace the Pi 4 or find a Pi Hat that works.
Yeah I doubt there’s a workaround at all for 1.5. Pretty frustrating.
I returned my HifiBerry hat and purchased the Allo DigiOne, it worked right off the bat and sounds really good to my ear.
I have the same problem with Orchard audio Pecan Pi Dac. Two weeks ago everything was OK.
Thanks it worked! Just upgraded to 3 and have wasted most of the day getting back to where I was.
Just got this error , using a Schitt Modi 2 Uber as my DAC, checked connections, still errors, power cycled Pi3 and Uber, that resolved it
Oh my god this actually worked, THANK YOU so much!
I was certain that it will NOT work because - WHY would I need to jump on one leg and hold my left ear for something like this to work?
But it did work and I am very thankful.
My board is Raspberry Pi 3 B+ (PCB v1.2)
with HiFiBerry Digi+ HW 1.3
Volumio v3.378
This is killing me. I have a Rasp Pi3 with IQaudiO DAC+. I originally used volumio v3 and got exactly this problem. The 'solution; did not work. I reburned the chip to the latest v2 and it does have the old interface, but the problem remains and the solution still doesn’t work. Is there ANY way to get this working??
I also have this issue since upgrading my Raspi400 to the latest software…
The Dac is a USB M2Tech Young ( Burr Brown) that worked nice with the previous software release…
Let me know what can I do for fixing the error alsa device already used???
Hi all,
I experienced what might be the same issue last night. I’m running volumio on Ras.Pi 3 with an Iquadio Dac Plus.
A few nights ago, I installed the current version of volumio added the HAT, and all worked fine.
This issue started when I tried to add a power button-- GitHub - Howchoo/pi-power-button: Scripts useful for the Pi power button
I pulled and installed that file, and immediately experienced the “Alsa failed to open” error. When I switched my audio output to the normal onboard headphone jack, it worked fine.
I fixed the issue by uninstalling the pi-power-button program and restarting. The DAC worked immediately after.
It looks like the audio DAC HAT uses the same pin as that project, so the it stopped working as soon as I added that additional project. I’m not sure if this is the same issue as any of you were experiencing, but maybe check the Digi+ Pro documentation for pins used if you have any other projects loaded.
Hope that helps anyone out there. But, in reading through this board more thoroughly, it looks like people’s issues stem from RasPi 4, version 1.5 not integrating well with HiFi berry Dacs. Well, in any case, I thought I’d post in case anyone else has the same issue as me.
Not sure if that’s impacting the rest of you.
I also have this issue with Rpi3 and Pimoroni Audio Amp SHIM. Worked fine on 2 and was working initially, suspect the culprit was installing the Rotary Encoder II plugin - so looks GPIO related.
Hi,
Should you encounter this error again, my best advice would be to take out your SD card and re-install Volumio from scratch.
Once it is all configured, write down your settings and find anotehr SD Card. Install Volumio to that one and apply the settings. Check if they work.
So in case you need it, you’ll have a back-up system ready to go.
You can also install something else to that back-up card…
Me, my Volumio 2.9.17 stopped working. I could do whatever I wanted : no go. Reinstalled. There you go At first try, it worked.
MAGIC
You are my god! Works fine for me!
I know this thread is a little older but still today it’s an issue. My Volumio Pi has been doing this for a few months. No hardware was changed and it worked perfectly for over a year before, so I assumed it had to be software.
After trying several other things, for me the solution was to do a fresh install of Volumio with the latest image (although my system was already updated when the problem accured).
