Installing TauDAC drivers for Volumio 2.526

Volumio version 2.526 comes with linux kernel 4.14.92. Unfortunately, I did not managed to provide the TauDAC drivers for this kernel before this Volumio version was released. Hence, the TauDAC is not going to work with Volumio version 2.526. But this can be fixed easily:

  1. Login to your Raspberry Pi.
  2. Change to the root directory:
    cd /
  3. Download the TauDAC kernel modules archive:
    sudo wget
  4. Extract the archive / Install the modules:
    sudo tar -h --strip-components 1 --exclude *.hash -xf rpi-volumio-4.14.92-taudac-modules.tar.gz
  5. Optionally, remove the archive:
    sudo rm rpi-volumio-4.14.92-taudac-modules.tar.gz
  6. Finalize the installation:
    sudo depmod
  7. Reboot:
    sudo reboot
  8. Done, the TauDAC drivers should be installed now. You can double check it with:
    aplay -l

Mounting NFS directories using AutoFS

AutoFS allows to automatically mount network shares on demand. Compared with traditional fstab configurations, using AutoFS has the following benefits.

  • With AutoFS, directories are automatically mounted when they are accessed and are unmounted after a period of inactivity — can reduce boot time and improve overall performance.
  • Auto-mounting via fstab will fail if the network connection to the network share is not yet established during boot time (common issue with WiFi netwoks) —  not an issue with AutoFS, as the shares are mounted on demand.

However, mounting a NFS directory using AutoFS requires a little more work, compared to adding a rule to the /etc/fstab file, here is an example.

Install dependencies:

sudo apt-get install autofs5

Create a mount point:

sudo mkdir /nfs

Configure the mount point, add the following line to the end of the file /etc/auto.master:

/nfs /etc/auto.nfs --ghost

Note: That line tells the AutoFS service that the mount points under /nfs are configured in file /etc/auto.nfs.

Add the following line to the file /etc/auto.nfs (create the file if it does not exist and adopt the hostname of the NAS and the name of the NFS directory):

music -fstype=nfs,ro,noacl,noatime,nodiratime,noac,tcp mynas:/volume1/music

Note: In the example above, the NFS share is mounted read-only, with some flags to optimize performance. Adopt the NFS mounting options to your needs, if necessary.

Restart the AutoFS service:

sudo systemctl restart autofs
