echo "Ask RTKit directly for the speaker tuning's realtime priority"

# The tuning host asked for realtime through xdg-desktop-portal. A portal started
# before rtkit was installed reports a realtime budget of zero; module-rt applies
# it as a hard RLIMIT_RTTIME of 0, RTKit still makes the data thread realtime, and
# the kernel kills the host as soon as audio plays. The host config is only copied
# by `omarchy-audio-tuning on`, so an installed tuning keeps the old one until
# replaced here.
#
# Only Omarchy's own copy with the old setting is replaced. A community
# calibrator can host its graph under the same file name, and a tuning graph is
# never touched: `omarchy-audio-tuning on` would overwrite one it did not write.
