Does Volumio support HiFiBerry DAC+DSP?

Chris_Martini · June 9, 2020, 7:18pm

Looking to setup a RPi 4 (4gb) & HiFi Berry DAC+ DSP combo. Does Volumio support this board?

panch · June 10, 2020, 1:17am

yes I am using the combination, to use the DSP you need to install python 3.5 and pip3 before you install dsptoolkit.

rest you just follow the prompts on Volumio

found all the old links
edit config.txt

To install python 3.5 use this guide

Then

bash <(curl https://raw.githubusercontent.com/hifiberry/hifiberry-dsp/master/install-dsptoolkit)
make sure there are no errors

Excellent! Thanks for the quick response and help!

Hi Chris, just marked the post by ‘panch’ as solution … please delete if you don’t feel that it has answered your question.

I’ve had some issues trying it this way. After I tried fixing the issues I ended up reformatting the sd card and started over. Second time I had other show stopper issues. Third time reinstalling Volumio I checked and noticed it has Python 2.7.9 by default. Why can’t I just use the python version that’s already there with dsptools or update to a later python version (seems like 3.6x works best)?

panch · June 27, 2020, 5:04am

yepp, dsptools needs 3.5 /3.6 ( but not 3.8) and Volumio is stuck on 2.7.9

hence the long process to upgrade Python first and then only installing dsptoolkit. And keeping fingers crossed.
As soon as I had a working system, i just created another image which is now my starting point in case I mess up again or upgrades go bad…

Thanks Panch.

The issue I am running into is after the seeming successful Python 3.6.5 install:

sudo pip3 install --upgrade hifiberrydsp returns an error once it reaches the step of installing the lxml package. It fails with error code 1:

panch · June 27, 2020, 4:29pm

send the output of
python -V
python3 -V

if you get error for python3 you might have to setup the path

panch · June 27, 2020, 5:03pm

i think you need to set the path options , and try to install dsptoolkit

try the curl script

Chris_Martini · June 27, 2020, 7:35pm

Thanks, tried your suggestions, but upon running the curl script, at some point it returns:

let me find a spare card and try from scratch

Chris_Martini · June 28, 2020, 2:24pm

That is much appreciated!

panch · June 30, 2020, 1:34am

ok this is what I did

sudo apt-get install build-essential libc6-dev
sudo apt-get install libncurses5-dev libncursesw5-dev libreadline6-dev
sudo apt-get install libdb5.3-dev libgdbm-dev libsqlite3-dev libssl-dev
sudo apt-get install libbz2-dev libexpat1-dev liblzma-dev zlib1g-dev
cd $HOME
wget https://www.python.org/ftp/python/3.5.2/Python-3.5.2.tgz
tar -zxvf Python-3.5.2.tgz
cd Python-3.5.2
./configure  
make
sudo pip3 install -U pip
sudo pip3 install -U setuptools

reboot

bash <(curl https://raw.githubusercontent.com/hifiberry/hifiberry-dsp/master/install-dsptoolkit)

reboot

then setup volumio   (configure volumio like which dac, size of web art etc)

panch · June 30, 2020, 5:19am

my mistake, setup means configure volumio like which dac, size of web art etc

Chris_Martini · June 30, 2020, 5:26pm

Sadly, ran into more issues:

sudo apt-get install build-essential libc6-dev does not work until I do this:

apt-get update
apt-get install apt-file
apt-file update

Then all proceeds well until:

sudo pip3 install -U pip - Error is returned: sudo: pip3: command not found

Seems like the version of pip installed doesn’t support the version of python. So I did this to uninstall pip and reinstall the system pip:

sudo apt purge python-pip python3-pip
sudo rm -rf /usr/local/lib/python2.7/dist-packages/pip
sudo rm -rf /usr/local/lib/python3.4/dist-packages/pip
sudo apt install python-pip python3-pip

Now when I try to run:

sudo pip3 install -U pip

I get this error:

ImportError: No module named 'pip._internal’

Chris_Martini · July 1, 2020, 4:43pm

RE: This error -
ImportError: No module named 'pip._internal’
When I do:
python -V i’m getting version 3.4.2 despite having installed 3.5.2 according to the instructions above. This prompted me to check the ~/.bashrc for an alias. None exists.

So why is python3 still referring to 3.4.2 if i’ve installed 3.5.2? The mystery deepens…

panch · July 2, 2020, 1:46am

try a uninstall or

what I will suggest take another SD card install just volumio and see if python3.4 is installed, or follow the steps, and see who is doing it

Chris_Martini · July 2, 2020, 4:22am

Volumio by default has python 2.7.9 out of the box. When trying to install python 3.5.2, python 3.4.2 installs??!!! Not sure why. Those two (2.7.9 & 3.4.2) appear in usr/bin but 3.5.2 does not, despite my having compiled and installed 3.5.2.
I’m afraid that’s where my skill ends at Linux command line. I’m officially stumped for now.

servido · July 5, 2020, 8:49pm

Hi, I see you have Python 3.6.5 installed. I need python 3.6 so I install it but now I cant make it default
~ python -V
Python 2.7.9
~ python3 -V
Python 3.5.3

Python 3.6 is installed but cant make it default, tried adding an allias on bashrc but can make it work
~ which python3.6
/usr/local/bin/python3.6

Any advice about this?

Thanks
