My Raspberry Pi 3 Config.txt for Volumio

My stable configuration file for Volumio looks like this now:

1. Basics:

   initramfs volumio.initrd
   gpu_mem=16
   max_usb_current=1
   disable_splash=1
   

2. Sound card:

   dtparam=audio=on
   dtparam=i2c_arm=on
   dtoverlay=hifiberry-dacplus
   dtoverlay=lirc-rpi:gpio_in_pin=26
   

3. WaveShare screen:

   max_usb_current=1
   hdmi_group=2
   hdmi_mode=87
   hdmi_cvt 1024 600 60 6 0 0 0
   hdmi_drive=1
   

4. Network:

   auto lo
   iface lo inet loopback
   
   allow-hotplug eth0
   iface eth0 inet dhcp
   
   allow-hotplug wlan0
   iface wlan0 inet manual
       wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
       post-up ifdown eth0
   iface default inet dhcp
   

The only more convoluted configuration is the networking, which allows me to connect to my wireless network. Once the setup will be stabilised, I will be able to connect it via ethernet, making the whole last section obsolete.

And the wpa_supplicant.conf file looks like:

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

network={
  ssid="ssid"
  psk="passphrase"
  id_str="Home"
  proto=RSN
  key_mgmt=WPA-PSK
  pairwise=CCMP
}

HTH,
