Sound Config moOde 7

[morehifi]

how is your config? did you change something? do you use Edwards Tweak?
mpd.service -config?

I start with same config as moOde 6. but do not hear a difference.

Hi,

I also tried to isolate two cpus for using them with squeezelite only.
Therefore I modified /boot/config.txt and added:

Code:

isolcpus=2,3

after rebooting my pi I checked if the isolation is in place. But it wasn't

Code:

cat /sys/devices/system/cpu/isolated

I then added the isolation kernel parameter "isolcpus=2,3" to /boot/cmdline.txt

Code:

cat /boot/cmdline.txt

net.ifnames=0 isolcpus=2,3 console=serial0,115200 console=tty1 root=PARTUUID=067e19d7-02 rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait

And voila

Code:

cat /sys/devices/system/cpu/isolated
2-3

It worked.
Next I changed some parameters in /lib/systemd/system/squeezlite.service

Code:

CPUSchedulingPolicy=fifo
CPUSchedulingPriority=70
CPUAffinity=2,3
Nice=-18

(no need to add "/usr/bin/taskset - c 1,3". if you use the CPUAffinity parameter)

Restarted the service

Code:

sudo systemctl daemon-reload
sudo systemctl restart squeezlite

... and the sound is now definitely better (and it was already very good!)
