I2s Soundcard on Nanopi M4V2?

rothchild · 14 November 2020 15:00

Has anyone got this working?

I found this guide: https://forum.armbian.com/topic/11721-nanopi-m4-audio-i2s-output-on-gpio/

I’ve tried poking about a bit with it but I lack the general skills to work out what I might have done wrong when it didn’t work.

I’ve got a Terradac 9023 that I’d really like to use with this board - setup was always so easy on regular Pi’s using Diet Pi but nothing on this FriendlyArm board seems to quite work as it should it’s already been relegated (having been bought to be a Kodi box) to the secondary music server box, but even this isn’t going well!

Also I’m having trouble getting mopidy-spotify on to it (so it’s failing pretty hard as far as a music box goes so far! )

Any pointers gratefully received

This is the problem I’m hitting with Mopidy-spotify, it seems to be a mismatch between where pip is expecting to find the build tools it needs to compile this element and the reality of where they’re actually installed?

Hi,

maybe you can have a look to this guide for installation of pyspotify https://pyspotify.readthedocs.io/en/latest/installation/

This is the section for libspotify https://pyspotify.readthedocs.io/en/latest/installation/#libspotify

probably it would need to be installed

apt install libspotify-dev

But that it was that simple!

Why can’t I get apt-mopidy to work?

(it works fine on both a regular raspberry pi and also on a NanoPi Neo)

I did the following

wget -q -O - https://apt.mopidy.com/mopidy.gpg | sudo apt-key add -
wget -q -O /etc/apt/sources.list.d/mopidy.list https://apt.mopidy.com/buster.list
apt update

and my system was able to locate the package now

Thanks for persisting with me Joulinar, as far as I can tell those are the same commands with sudo removed from them. For the record:

not sure if this is related but you should remove the Ubuntu source list. DietPi is based on Debian and you should avoid mixing it with Ubuntu.

http://ppa.launchpad.net/spocon/lovspotify/ubuntu bionic InRelease

another option might be, libspotify-dev is not available for your board. But there I’m not an expert. Maybe MichaIng has an idea.

btw can you share you /etc/apt/sources.list.d/mopidy.list

rothchild · 14 November 2020 22:22

This is /etc/apt/sources.list.d/mopidy.list

# Mopidy APT archive
# Built on Debian 10 (buster), compatible with Ubuntu 19.10 and newer
deb https://apt.mopidy.com/ buster main contrib non-free
deb-src https://apt.mopidy.com/ buster main contrib non-free

The lovspotify thing seems to be working, well it’s running, as an extension of the original post I’m also enjoying hardware issues where I can’t get the i2s card working but actually I can’t get the onboard codec card working either!
