FiiO K1 became very silent recently when you plug it in on Ubuntu for some reason.

To fix it add an UDEV rule:

/etc/udev/rules.d/71-fiio-k1.rules

SUBSYSTEMS=="usb", ACTION=="add|change", ATTRS{manufacturer}=="FiiO", ATTRS{product}=="FiiO USB DAC K1", RUN+="/home/ajnasz/bin/init-fiio-k1.sh"

And create the shelscript which set the volume whenever you plug the DAC:

/home/ajnasz/bin/init-fiio-k1.sh

#!/bin/sh

CARD_ID="$(aplay -l | grep "FiiO.*K1" | cut -d ' ' -f 2 | tr -d ':')"

if [ -z "$CARD_ID" ];then
    return
fi

amixer -c "$CARD_ID" sset PCM 90%

Then reload the udev rules

udevadm control --reload
