Dragonfly 1.2 noise

I installed lasted volumio onto my Raspberry Pi and plugged in a DragonFly 1.2 DAC.

When I play something via AirPlay I only hear noise, no actual sound :frowning:

Tried to play with various setting in the web interface with no luck…, any suggestions ?

I logged in via SSH, started shairport with verbose option (-vvv) and observed it is trying to communicate via IPv6 getting errors. I disabled IPv6 this way:

placed this at the end of /etc/sysctl.conf:

net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1
net.ipv6.conf.eth0.disable_ipv6 = 1

Then I found out /etc/sysctl.conf is not applied at startup, so I placed this line in /etc/rc.local:

/sbin/sysctl -p /etc/sysctl.conf

Now I am able to use AirPlay and stream music, however sometimes there are scratches and clicking at the max volume regardless of the current level, any ideas how to fix those :slight_smile:?

Nevermind, I installed a fresh Raspbian, then applied the firmware patch (rpi-update), compiled shairport on the box, and everything works great without clicks and pops. So I guess something is wrong with sound settings in Volumio…
