Berryaudio and Camebridge dacmagic

[CharlieB]

I've downloaded and replaced 'mixers.json' in /home/pi/berryaudio/mixer/, restarted but when I go into 'Mixer' and click 'Select Device' there is not a single entry, although I can see all the mixers in the json file, the Cambridge Dacmagic100 included.

Ah sorry I missed out on a comma, use the attached file

Thanks! I can select the Cambridge Dacmagic 100 in the Mixer now but I'm still not getting anything from my speakers. I'm getting desperate; I got the manual from the amplifier out to check the cable connections. Everything looks like it's supposed to be looking. When I disconnect the cable from the Dacmagic to the amplifier on the Dacmagic side and touch the jack with the connection pin on the Dacmagic I'm getting a humming sound from the speakers. I don't know if this can be considered as a reference?
Is there anything else we can try?

Thats humming seems to be noise
From a floating ground to the amp which is okay and means your amp is working

i am still looking for online references for missing configs where users have got it working with dacmagic

I've hooked a turntable up straight to the amplifier and I'm getting music from the speakers so all good there.

I'm trying Moode now. I just had to select the Dacmagic100 in raspi-config and it works great. The interface is a dragon though and it is sluggish as hell compared to Berryaudio so if you would be able to put in the time and effort I would switch to Berryaudio in a heartbeat again.
Searching the net I found quite a lot of people are using the Dacmagic100 for their music platform. I still have Berryaudio installed on a separate RaspberryPi. I would be happy to test configurations for the Dacmagic100 for you to make it work.

Thank you for sharing this information. i am very keen to make this work with your support , I will check out moode audio config for dacmsgic today

Since the DAC is already been detected lets try using plughw:CARD=C2,DEV=0. to see if its working and let me know the results for the following tests

Test 1:
sudo systemctl stop berryaudio.service
sudo systemctl stop camilladsp.service

aplay -D hw:CARD=C2,DEV=0 /usr/share/sounds/alsa/Front_Center.wav

Test 2:
sudo systemctl stop berryaudio.service
sudo systemctl stop camilladsp.service

aplay -D plughw:CARD=C2,DEV=0 /usr/share/sounds/alsa/Front_Center.wav

Test 1 :

pi@berryaudio:~$ sudo systemctl stop berryaudio.service
pi@berryaudio:~$ sudo systemctl stop camilladsp.service
pi@berryaudio:~$ aplay -D hw:CARD=C2,DEV=0 /usr/share/sounds/alsa/Front_Center.wav
ALSA lib confmisc.c:165:(snd_config_get_card) Cannot get card index for C2
aplay: main:831: audio open error: No such device
pi@berryaudio:~$

Test 2 :

pi@berryaudio:~$ sudo systemctl stop berryaudio.service
pi@berryaudio:~$ sudo systemctl stop camilladsp.service
pi@berryaudio:~$ aplay -D plughw:CARD=C2,DEV=0 /usr/share/sounds/alsa/Front_Center.wav
ALSA lib confmisc.c:165:(snd_config_get_card) Cannot get card index for C2
aplay: main:831: audio open error: No such device
pi@berryaudio:~$

Hmm that shows that the pi is not able to get any audio out of the DAC, even though it can see the device

Is the device connected to the pi usb port?

can you following command --> lsusb

also is the amp turned on while testing this?
