ProtoDAC TDA1387 X8 project

[Tim Curtis]

Here is another option for installing the yml file. Just tested on my end and no issues.

Code:

# Install file
wget -q "https://moodeaudio.org/test/ProtoDAC VC.yml.zip"
unzip "ProtoDAC VC.yml.zip"
sudo cp "ProtoDAC VC.yml" /usr/share/camilladsp/configs/
chmod 0666 "/usr/share/camilladsp/configs/ProtoDAC VC.yml"

# Confirm format and permissions
pi@moode:~ $ file "/usr/share/camilladsp/configs/ProtoDAC VC.yml"
/usr/share/camilladsp/configs/ProtoDAC VC.yml: ASCII textpi

@moode:~ $ ls -l "/usr/share/camilladsp/configs/ProtoDAC VC.yml"
-rw-rw-rw- 1 root root 1188 Jun 15 07:18 '/usr/share/camilladsp/configs/ProtoDAC VC.yml'

After setting the config in CamillaDSP but before playback confirm the volume proxy is running

Code:

pi@moode:~ $ sudo systemctl status mpd2cdspvolume.service

Jun 15 07:18:44 moode systemd[1]: Started Synchronize MPD volume to CamillaDSP.

Be aware that this config results in -3dB lower volume to prevent clipping so when turning it on/off there will be difference in loudness i.e., Software volume will be louder.

You can also see the Camilla volume in action and examine the filter by opening the Pipeline editor.

ETA: Also turn on "Display dB volume" in the MPD options section of Audio Config.
