NanoSound CD Plugin for Volumio – Support

Thanks for supporting NanoSound CD – The best CD playing and extraction plug-in for Volumio 2.x.

At this stage, Nanosound CD does not work with Volumio 3.x yet, this is due to VLC dependencies not available in Volumio 3.x

Installation Instructions

Method 1 – Install from volumio plugin repository

IMPORTANT NOTE WHEN USING volumio version 2.882 or above

Visit http://volumio.local
Go to Settings -> Plugins
Under Search Plugins, find NanoSound CD and install
Installation does take quite a bit of time (15 – 30mins)

Method 2 – Run the installation script

Always get latest using this method

Download installation script from above
Use Putty to SSH volumio.local . Default login and password are both “volumio”
Copy and paste the commands in the installation scripts and run them

Be patient, even with a fast broadband connection, it will take around 15 – 20minutes to complete. It will appear to be at “Progress: 70” for a long time. This is normal.

To monitor the installation progress, use below command:

sudo journalctl -f

After installation, a reboot required. This is because the alsa sound modules settings are changed.
Enable the NanoSound CD plug-in under Plug-in

To verify that installation is ok, check below services are running by running below commands:

systemctl status nanosoundcd_web

systemctl status nanosoundcd_progressweb

Method 3 – Pre-installed Volumio image

When you have trouble with method 1 and 2, you may try this method.

Usage

Playback

Once the NanoSound CD plug-in has been installed, to play CD, go to browse and choose Nanosound CD
This video would help you with CD playback. Upsampling options are available in NanoSound CD settings.

Audio Extraction

For CD Extraction, there are 2 ways currently:
- In Extract CD section under NanoSound CD settings

- A work in progress interactive interface can be accessed via http://volumio.local:5002/
By default, the extracted files are saved in the microsd card (/mnt/INTERNAL). If you want to change the location, you can change the settings in NanoSound CD plug-in settings:

Extraction to NAS

To save to NAS drive, enter ‘NAS/your-share-name’
- Setup your NAS alias via Sources -> Add New Drive

For example, in windows, the drive is \\192.168.11.6\Multimedia\extracted

- To set your extraction destination to NAS, make sure you specify ‘rw’ in options in your NAS mount. This will allow write access to your mounts under /mnt/NAS. In this example,
  - NAS IP Address: 192.168.11.6
  - Path: Multimedia/extracted
  - Options: rw (for some older NAS models , try Options: rw,vers=1.0)
  - Username / Password: username / password to login to your NAS, make sure it has read write access. Leave blank for guest.

- To verify that your NAS mount is setup correctly, login to your volumio system and run below command.

- if you would like to store the extracted audio files to below NAS share, in NanoSound CD plug-in settings, set Extraction to Path to ‘NAS/extmusic’

Extraction to USB

To save to USB drive,
- From version v.1.1.2, enter ‘USB’. It will automatically choose your USB flash drive if there is only one inserted.
- Enter ‘USB/your-usb-volume-name’. To check your volume, you can either check from your Pi or computer. Note that it’s case sensitive

Computer

- In this case, the usb volume name is “MYUSBDRIVE”, therefore below should be set in the extraction path

Artist and Album name in extracted folder

This is available from version 1.2.

In “Extract Folder Format”, you can now specify the format of the extracted folder. For example, “%artist%-%album%” will output a folder such as below:

Integration with NanoSound DAC

NanoSound CD seamlessly integrates with NanoSound DAC to leverage on the display, control buttons and remote control. However, NanoSound DAC is optional, so you can use any DAC with NanoSound CD. If you are using NanoSound DAC, we highly recommend you to upgrade your NanoSound volumio plug-in to v1.6 or above.

Nanosound Plug-in V1.6 for Volumio

Volume Options

The best volume options depends on the DAC hardware you use and your setup. The volume option is set under PLAYBACK OPTIONS in volumio

Here are the recommended settings.

If you do not need volume control, since you would like volume to be controlled by an external amplifier:

Mixer Type: None

NanoSound DAC / DAC2 and i2s DACs which supports hardware volume

Mixer Type: Hardware
Mixer Control Name: Digital

i2s DACs which does not support hardware volume

Mixer Type: Software
You need the latest version (2020-10-26 or later). Use the “Show Version” button to check. If needed, use the “Upgrade Version” button in NanoSound CD to upgrade
In /data/configuration/music_service/nanosound_cd/ create a file called alsadevice.json, and put below into the content. This will override the alsadevice to softvolume

{
"alsadevice": {
"type": "string",
"value": "softvolume"
}
}

Audio Jack (i2S DAC off)

Mixer Type: Hardware
Mixer Control Name: PCM

USB DACs

Mixer Type: Hardware
Mixer Control Name: PCM

Upsampling for USB DAC

Auto config is now working for USB DAC since 2020-01-11, so you wont need to manually edit the file anymore.

If you are using USB DAC and upsampling is not working, please follow below steps:

check your card id.
```
cat /proc/asound/modules
```
For example if you:
```
0 snd_bcm2835
5 snd_usb_audio
```
so card5 is our USB DAC.

find out capabilities of your the DAC

cat /proc/asound/card5/stream0

In this example, this USB DAC can only do 96000 max. Many other USB DAC can do higher.

- edit /etc/asound.conf and it should look like

</data/nanosound_cd/asound.conf>

edit /data/nanosound_cd/asound.conf and replace hw:5,0 and card 5 with your card number if needed. Restart NanoSound CD plugin.

defaults.pcm.rate_converter "speexrate_best"
pcm.!default {
type plug

Troubleshooting / Advanced Config

Make sure your CD/DVD USB drive does not draw too much power. The Sony and Pioneer one which we sell draws around 1A and can be directly powered via Raspberry Pi, other drives might need external power. Please let us know (email to [email protected] ) if certain drives works well or not.
To verify that installation was successful, go to NanoSound CD plugin settings and click “Show Version”. A green box will popup showing the date of the release
If there is no sound coming out while playing CD:
- Try the Auto Audio Reconfig function under NanoSound CD. This will attempt to select the best audio device for you. Reboot after running it.

- Check if there is enough power for the CD/DVD drive. Use an external power supply if in doubt.
If uninstalling the plugin doesn’t work, you can try removing the NanoSound CD plugin via below commands
- Load http://volumio.local/dev and enable ssh if you haven’t done so
- Use terminal software such as putty to ssh to volumio.local (default user name and password are volumio / volumio)
- Run below commands and ignore if any errors:

sudo /bin/systemctl stop nanosoundcd_web

sudo /bin/systemctl stop nanosoundcd_progressweb

sudo /bin/systemctl disable nanosoundcd_web

sudo /bin/systemctl disable nanosoundcd_progressweb

sudo rm /lib/systemd/system/nanosoundcd_progressweb.service

sudo rm /lib/systemd/system/nanosoundcd_web.service

sudo /bin/systemctl daemon-reload

sudo rm –r -f /home/volumio/nanomesher_nanosoundcd

sudo rm –r -f /home/volumio/python-audio-tools/

sudo rm –r /data/plugins/music_service/nanosound_cd

```
If you have tried above steps and still get no sound:
```
- Drop an email to [email protected] and attach these 2 files:
  - /etc/asound.conf
  - /data/nanosound_cd/asound.conf
  - Specify your DAC model
  - output of command “aplay -l”
  - output of command “cat /proc/asound/modules”
  - output of command “cat /proc/asound/cards”
