Final System Setup
Existing audio gears
- Files USB hdd (on Asus RT-AC68U router)
- System TomatoUSB on Asus RT-AC68U router
- Software MPD
- DAC built-in USB (Musical Fidelity A1)
- Amplifier Musical Fidelity A1 Integrated Amplifier
- Speakers Focal Aria 926
- Subwoofer Acoustech PL-200
DAC upgrade for sound quality and DSD support
- DAC SMSL M8 ES9018K2M 24Bit/384KHz (XMOS USB, coax, optical)
Asus RT-AC66U not recognize SMSL M8 - Switch to Windows
- Files Samba shares from Asus RT-AC66U router
- System Windows 10 laptop
- Software JRiver
Switch to low watt MPD with SMSL M8 support
- System Raspberry Pi 3
- Distro RuneAudio
MPD based Distros:
Moode
hard to reach bit perfect output
Rune
bit perfect ready
DSD ready
very satisfying result
Volumio
satisfied with Rune
no chance to try yet
Add video player (on another SD card)
- Distro OSMC
- Display LG 55LM7600
Kodi based Distros:
- OpenELEC
limited customizable
- OSMC
satisfying result with some other great skins
Unify to a single SD card dual boot
- Software NOOBS
Multi Boot:
- BerryBoot
can install directly to USB drive
support HDMI CEC
squashfs filesystem needs some skills and patient
Rune outputs loud static noise with some USB DAC
- NOOBS
manageable customizing
filesystem can be extracted directly from image file
Customizing for easy switch between Rune and OSMC
- Device Mouse with modified on-screen UI
Customizing for consistency and easier switch and control
- Device USB PC remote (dirt cheap on eBay)
Remote Control:
- HDMI CEC - OSMC only
need no additional device but the TV must support CEC
cannot control NOOBS
automatic switch input hassles
- ir module - NOOBS + OSMC
can receive any signal but a lot of key code detection
need a lot of keymaps
cannot control NOOBS
cheap but need DIY enclosure
- ir USB PC Remote - NOOBS + Rune + OSMC
recognized as a keyboard and mouse
control NOOBS boot menu
work in Rune with a single config file
ready to use without settings in OSMC
cheap and easy to install to USB
Configuration:
- Rune
not directly support keyboard
use XbindKeys to map keyboard key to command
detect ir code
- OSMC
directly support keyboard
detect ir code with Keymap Editor addon
create /home/osmc/.kodi/userdata/keymaps/keyboard.xml
restart keymaps
map 'reloadkeymaps' command to a key
add /home/osmc/bootrune.py
Add remote control for power on/off in sequence
- Device Relay module control by GPIO (dirt cheap on eBay)
Remote Control
- AC power:
switch on/off amp, pre-amp, DAC in sequence
autoswitch off on idle
autoswitch off on shutdown
RPi.GPIO
- Rune
edit 'sudoers' to allow no-password sudo
use php sudo to call python script that cannot sudo by itself
use 'python-mod2' to monitor idle
use python 'requests' for pushstream notification
use pushstream message for GPIO button updating
- OSMC
('sudoers' already no password)
use python sudo to call python script that cannot sudo by itself
use python 'requests' for json-rpc
monitor idle
notification
Unify Remote Control
- Devices JP1 remote (universal programmable)
JP1 FTDI USB to serial cable
- Software RemoteMaster
- JP1 Remote learn any remotes
most remotes code available for download
discrete on, discrete off, discrete input
map any signals to any keys
macro signals
Tweaks
- Make installation unattended
append silentinstall to cmdline.txt
custom compile NOOBS to auto reboot on finished
- Auto switch audio output to USB
Rune
replace mpd.conf with on.py
OSMC
get udev parameters
create udev rules
- Change OSMC root ssh login to be the same as Rune
- Modify on-screen user interface
Rune
add 'amp' on/off button
add 'bootosmc' menu
OSMC
add 'amp' on/off menu
add 'bootrune' menu
Transfer from SD card to USB drive
- transfer static files
- set boot partition in /boot/cmdline.txt
