Can confirm this is working beautifully now with the pi3 and the x400 which arrived in the mail today. Sounds great!
I hope to play around with the backend of Arch in a week or two when my DVB-T dongle arrives. It should be able to decode FM and DAB+ radio via command line apps. If I can get that working then maybe the devs will help me integrate it into the main image. I'll also see if I can get a USB powered dvd burner working to play normal audio cds as well as possibly DTS dvd if the pi has enough processing power.

Thanks to frank and the devs for updating to pi3, I appreciate it

I've got the same but file "bcm2710-rpi-3-b.dtb" is in "boot" directory.
So you can use curl to download it in boot.

Then you have to reboot your pi to get the right sound.

Thanks for the help. It works perfect.

the new image is ready and available here

Have installed and it's working great with my Pi3/IQ config. Whilst setting up I have noticed the advice given and disabled the software volume and it has given the sound quality a discernible boost, even happier than before!


I can confirm the above. This new beta works like a final release! Perfect work! Thank you very much! For me its much more usable than the other similar (debian based) audio systems.

+1 for multiple track selection in the UI / Queue would be fine

Everything is OK..

Could you add a option to mpd setting: increase volume DSD +6db as other player ( jriver, audivarna, roon)

Thank

Thanks for the quick update the for the RPi3! This was fast.
Although it seems to boot and recognise my RPi3 with the IQAudio Digi Amp just fine I'm struggling to get a sound out of this combination. It seems that the Digi Amp is muted on each boot. Would it be possible to include an unmute on boot option in RuneAudio for this device?

Hi Bivabdaud,

I had the same issue (but for the IQAudio Pi-Amp+) and this is how I resolved it.

Create a file /usr/bin/unmute_amp with the editor or your choice and insert the following:

Code: Select all
#!/bin/sh
echo "22" > /sys/class/gpio/export
echo "out" > /sys/class/gpio/gpio22/direction
echo "1" > /sys/class/gpio/gpio22/value


Make the file executable

Code: Select all
chmod a+x /usr/bin/unmute_amp


Create a file /etc/systemd/system/unmute_amp.service and insert the following:

Code: Select all
[Unit]
Description=/etc/rc.local Compatibility
ConditionPathExists=/usr/bin/unmute_amp

[Service]
Type=forking
ExecStart=/usr/bin//unmute_amp start
TimeoutSec=0
StandardOutput=tty
RemainAfterExit=yes
SysVStartPriority=99

[Install]
WantedBy=multi-user.target


Make the file executable

Code: Select all
chmod a+x /etc/systemd/system/unmute_amp.service


Use the following command to enable the service to start on boot-up

Code: Select all
cd /etc/systemd/system
systemctl enable unmute_amp.service


Reboot the Pi.

Hope this helps,

Or you could try the following:

Code: Select all
sudo nano /home/unmutepiamp
and then add the lines ...

Code: Select all
#Unmute the Pi-AMP+
echo "22" > /sys/class/gpio/export
echo "out" >/sys/class/gpio/gpio22/direction
echo "1" >/sys/class/gpio/gpio22/value

Then save & exit

Then do
Code: Select all
cd /home
chmod a+x unmutepiamp

This script is run at power up using cronie which must be installed so do ...
Code: Select all
pacman -S cronie


If you get a 404 error, do ...
Code: Select all
pacman –Syy cronie

Now do ...
Code: Select all
systemctl enable cronie.service
systemctl unmask cronie.service
systemctl start cronie.service
export EDITOR=nano
crontab -e
And insert following line ...

Code: Select all
@reboot sleep 5 ; /home/unmutepiamp


Then save & exit

Now check that cronie is running and that the cron job is there by doing ...
Code: Select all
systemctl status cronie
crontab -l


Hope this helps

Wow! I've been watching these forums for a couple of weeks deciding wether or not to get an rpi3 and iqaudio dac+ ... I got my kit delivered yesterday and had it put together and working in 15 mins. The longest part was trying to find a micro sd card in a drawer...

Frank, thanks for all your work. Its totally useable, the sound is mindbogglingly good, I dunno what else to say. Apart from my 7" screen arrives soon, hopefully that will take no more than 15 mins to set up! Then I'l have to make a case (I've got a chunk of Walnut lying about so I think I'll whack it on that.

Thanks again!

thanks for the fast help @RawDevice and @johnbanks! I will try both solutions as soon as I get back to my Pi. However it should be possible to include this into the RuneAudio build, right? Given the popularity of the IQ devices maybe it's a possibility for the future.
