If you follow https://github.com/e...en/forked-daapd you will get a lot of error-messages. 

 

Here is guide to install it on your Orange Pi Pc (Debian Jessie),

sudo apt-get install build-essential git autotools-dev autoconf libtool gettext gawk gperf \
  antlr3 libantlr3c-dev libconfuse-dev libunistring-dev libsqlite3-dev \
  libavcodec-dev libavformat-dev libavfilter-dev libswscale-dev libavutil-dev \
  libasound2-dev libmxml-dev libgcrypt11-dev libavahi-client-dev zlib1g-dev \
  libevent-dev

for Armbian you need some little extras installed

sudo apt-get install libcurl4-gnutls-dev 
sudo apt-get install libjson0 libjson0-dev
sudo apt-get install avahi-daemon avahi-discover libnss-mdns

then you run

 git clone https://github.com/ejurgensen/forked-daapd.git
 cd forked-daapd
 autoreconf -i
 ./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var
 make
 sudo make install

create the new user 

sudo adduser daapd

adjust the settings for your music-path in /etc/forked-daapd.conf

 

 on my Orange Pi, the file /etc/init.d/forked-daapd was missing. If yours is missing, too, just add it:

sudo nano /etc/init.d/forked-daapd

and copy this text inside:

#! /bin/sh

        fi

    N=/etc/init.d/$NAME
    echo "Usage: $N {start|stop|restart|force-reload|status}" >&2
    exit 1
    ;;
esac

exit 0

Save it. 

 

Now we need to allow the service access to it´s own database:

sudo chown -R daapd /var/cache/forked-daapd 

Start the service:

sudo /etc/init.d/forked-daapd restart
tail -f /var/log/forked-daapd.log

you should see some activity on the log-file. After the scanning is complete, you can see your Orange Pi music-server in iTunes.

 

Automatic updates for the music-server (e.g. at 4am in the morning, necessary if you use a network-share for the data):

sudo crontab -e

and add the line

0 4 * * * touch /{path to your music}/trigger.init-rescan

for chromecast you should try 

sudo apt-get install libjson-c-dev libgnutls-dev libprotobuf-c-dev

first. Then try to compile again.

Thanks, compile fine now

For armbian, there is no package libgnutls-dev, instead libgnutls28-dev

Script from #8 really works.

sudo nano /etc/systemd/system/forked-daapd.service

and paste the script from #8. 

sudo chmod +x forked-daapd.service
sudo systemctl enable forked-daapd.service
sudo systemctl start forked-daapd.service

after that continue from 

tail -f /var/log/forked-daapd.log

from #1.

 

I checked it on my OrangePi Zero with Armbian / Ubuntu Image

Is there a reason for you to compile it yourself? I've been using the version from the official packages for quite a while now. I remember there were problems long time ago with version 0.19. But since Espen Jurgensen took over the development (from forked-daapd >= 0.20) this works very reliable. Installation from the official repos is really easy...

when i tried to use forked-daapd for the first time, it just didn´t work with my iTunes (OS X and Windows 7). Later I found, that Apple changed some small parts of their software :)

Getting the most up-to-date version of forked-daapd solved the problem. And it was just available from source.

 

The developer is very active, so I always have a very good change to solve any kind of problem just by compiling myself.

for Armbian you need some little extras installed

 

You should be a bit more specific which distro you use. Armbian images were either Debian Wheezy, Jessie, Ubuntu Trusty or Xenial (support for Wheezy and Trusty removed a few hours ago). Usually Ubuntu images are more up to date (and sometimes faster since built with a more recent GCC version). So please add for which distro your instructions should apply.

Before you report any problem please be aware that crappy SD cards and insufficient power supply are reason N° 1 why things are failing. Try to rule this out first please, check 'getting started' recommendations and check/provide 'sudo armbianmonitor -u' output first!

 

Did you check out custom google powered forum search already (before opening new threads or asking questions)?

I have problem now playing from local audio output alsa

I want to play from card 1 : snddaudio

Anybody help?

I took the according name from the output of amixer and it works on my Banana Pi running Armbian Debian Jessie.

As example:
Excerpt from output of command "amixer":
Simple mixer control 'Power Amplifier',0
  Capabilities: pvolume pvolume-joined
  Playback channels: Mono
  Limits: Playback 0 - 63
  Mono: Playback 40 [63%] [-23.00dB]
Excerpt of my forked-daapd.conf:
# Localaudio output
audio {
  # Name - used in the speaker list in Remote
  nickname = "My Nickname"
  # Audio device name for local audio output
  # card = "default"
  # Mixer channel to use for volume control - ALSA/Linux only
  # If not set, PCM will be used if available, otherwise Master.
  mixer = "Power Amplifier"
}
Hope that works for you as well.
Cheers.

Edit: forked-daapd from official debian-jessie-repo (installed with: "apt-get install forked-daapd", version 22.0-2)

Device or resource busy

This looks like forked-daapd is trying to access the correct device, but there is another service/application running which accesses and thus blocks the audio device - or another application was running which used the audio device and didn't free the access again after using that audio-device.

Do you have an idea what that could be? Try to disable it (or maybe reboot) and then try again with forked-daapd.

I think we found the correct card and mixer. But with the "device or resource busy" problem I can't help any further. This you need to figure out yourself. Good luck :-)

This looks like forked-daapd is trying to access the correct device, but there is another service/application running which accesses and thus blocks the audio device - or another application was running which used the audio device and didn't free the access again after using that audio-device.

Do you have an idea what that could be? Try to disable it (or maybe reboot) and then try again with forked-daapd.

I think we found the correct card and mixer. But with the "device or resource busy" problem I can't help any further. This you need to figure out yourself. Good luck :-)

 

shairport-sync is using this audio device

however i didn't hard lock the device, instead i'm using .asoundrc in /home/shairport-sync

my understanding by doing this, hw:1,0 can be switched, activated upon usage selection, but seems it's not the case

do you know anyway to share same device by multiple application?

dmix if we are talking about ALSA, otherwise pulseaudio can do this too.

I do have already enable dmixer in .asoundrc

Am I missing something?

 

.asoundrc

-----------------------------------------------------------

pcm.snd_card {
        type hw
        card 1
        device 0
}
 
ctl.snd_card {
        type hw
        card 1
        device 0
}
 
pcm.dmixer {
    type dmix
    ipc_key 1024
    ipc_perm 0666
    slave.pcm snd_card
    slave {
        period_time 0
        period_size 1024
        buffer_size 4096
        rate 44100
        format S32_LE
        channels 2
    }

Yes, you need to set it as a default ALSA input or you need to tell your applications to use dmix explicitly (instead of "hw:1" it should be something like "plug:dmix" if I remember correctly.

 I change .asoundrc to this below, but still not working

-----------------------------------------------------------------------

pcm.!default {
    type plug
    slave.pcm "dmixer"
}

pcm.dmixer {
    type dmix
    ipc_key 1024
    slave {
        pcm "hw:1,0"
        period_time 0
        period_size 1024
        buffer_size 4096
        rate 44100
    }
    bindings {
        0 0
        1 1
    }
}

ctl.dmixer {
    type hw
    card 1
}

But you are still telling your applications to use "hw:1" directly and thus bypassing the dmix. If your default configuration is correct, you should be able to use something like "plug:default" in applications too.
