Hello everyone.

I`ve tried to configure the DAC based on Adau 1701 - I`ve choosed the HiFiberry in the setup window, and changed dtoverlay for chipdip-dac in the /boot/firmware/config.txt

alsa also was configured for work with hw:ChipDipDAC,0 and i could hear the test sounds using speaker-test -c 2 -t sine -f 440 -l 1

The next step was to configure alsaloop -C hw:Loopback,1,0 -P hw:ChipDipDAC,0 -t 50000 -f S32_LE -r 48000 -c
After that I`v=e managed to get the sound from the Berryaudio but it was very slow and distorted.
i suppose it was caused with the wrong DAC settings such as 48000Hz, LRCLC Left justified
, Data 1 bit delay. 24bit depth WS High Level, SD Data left channe etc

Unfortunately, chainging these parameters for alsaloop had no good - the sound still playing corrupted.

Maybe there should be a spcial config file to adjust, but I have no Idea where to find it.

Do you have any ideas where to dig next?

Thanks in advance.

Hi apologies for the late response, did you check the Camilla DSP settings and change the sample rate there to fixed sample rate?

Also I am planning a new release in the coming days that allows you to configure the DAC directly from the UI itself so may be that would help

Thank You for Your reply!

Actually I should check the project structure before asking such silly questions) Though it really took a time - the solution appeared to be really easy.

You were right - I had to check the Camilla DSP settings.

Just to share my experience - here are three steps to get started with Adau1701 + Berryaudio:

1. Adding the new DAC to UI - /home/pi/berryaudio/mixer/playback_mixers.json

One block added

{
"device": "plughw:ChipDipDac",
"name": "ChipDipDac",
"description": "ADAU1701 I2S Master",
"volume_control_mixer": "Digital",
"supports_hw_volume": true,
"supports_hw_mute": true,
"channel_count": 2,
"supported_sample_rates": [44100, 48000, 88200, 96000],
"supported_formats": ["S16_LE", "S24_LE", "S32_LE"],
"dtoverlay": "chipdip-dac"
}

2. Configuring DSP - /home/pi/builds/camilladsp/configs/camilladsp.yml

capture:
channels: 2
device: plughw:Loopback,1
type: Alsa
capture_samplerate: 48000 #Just to be sure
chunksize: 8192
enable_rate_adjust: null
multithreaded: true
playback:
channels: 2
device: multi_out
type: Alsa
samplerate: 48000


3. Making some changes for /etc/asound.conf


pcm.multi_out {
type plug
slave.pcm {
type multi
slaves {
ada { channels 2 pcm "plughw:ChipDipDAC" }
snapcast { channels 2 pcm "hw:Loopback,0,1" }
spectrum { channels 2 pcm "plughw:Loopback,0,2" }
}
bindings {
0 { slave ada channel 0 }
1 { slave ada channel 1 }
2 { slave snapcast channel 0 }
3 { slave snapcast channel 1 }
4 { slave spectrum channel 0 }
5 { slave spectrum channel 1 }
}
}
# Modified routing one stereo-in (2ch) three stereo out (6ch)
ttable [
[ 1 0 1 0 1 0 ] # Input L → Ada L, Snap L, Spec L
[ 0 1 0 1 0 1 ] # Input R → Ada R, Snap R, Spec R
]
}

And thats it.

no problem I am glad it worked out for you.
