Hello,
I am pretty new to Rpi and moodeaudio. I tried to summarize and combine different tweaks (thanks to all contributors) to optimize the sound of my Rpi which is connected to an external USB DAC. I have get a pretty good sound with these tweaks and settings:
1 – isolating procs
added in /boot/cmdline.txt: isolcpus=2,3
sudo pico /lib/systemd/system/mpd.service
CPUSchedulingPolicy=fifo
CPUSchedulingPriority=70
Nice=-16
ExecStart=/usr/bin/taskset -c 2,3 /usr/local/bin/mpd --no-daemon $MPDCONF
2 - config.txt
sudo nano /boot/config.txt
arm_freq=1000
sdram_freq=2000
core_freq=500
gpu_freq=500
over_voltage=-5
over_voltage_sdram=-5
gpu_mem=16
max_usb_current=1
force_turbo=1
initial_turbo=60
avoid_pwm_pll=1
3 - configure moode
SOX 32/352,6 medium
64 bits
This is a first share on my side. May be you can as specialists improve these settings.
Best,
