I'm not running squeezelite as root but the 'daadmin' user is a member
of the audio group. Here are my env vars and the portion of the sysv
init.d script where I launch the squeezelite daemon at startup:
/etc/default/squeezelite:
Code:
--------------------
SQLITE_DESC="Squeezelite v1.6.5"
SQLITE_BIN="/usr/local/bin/squeezelite"
SQLITE_USER="daadmin"
SQLITE_AUDIODEV="sysdefault:CARD=VX1"
SQLITE_OPTIONS=""
SQLITE_DEBUG="all=debug"
SQLITE_LOG="/var/log/squeezelite/squeezelite.log"
SQLITE_MAC="00:04:20:62:61:ae"
SQLITE_PLAYERNAME="SQUEEZENAS_SqueezeLite"
SQLITE_LMSIP="127.0.0.1"
--------------------
/etc/init.d/squeezelite:
Code:
--------------------
d_check_running() {
if [ -e $PIDFILE ]; then
pidofproc -p "$PIDFILE" "$SQLITE_BIN" > /dev/null 2>&1 &&
status=0 || status=$?
if [ $status = 0 ]; then
log_daemon_msg "${SQLITE_DESC} is already running"
log_end_msg 0
exit 0
fi
fi
}
d_start() {
d_check_running
log_daemon_msg "Starting" "$SQLITE_DESC"
if start-stop-daemon --start --quiet \
--chuid $SQLITE_USER \
--pidfile $PIDFILE \
--exec $SQLITE_BIN \
--background \
--make-pidfile \
-- \
-o $SQLITE_AUDIODEV \
-d $SQLITE_DEBUG \
-f $SQLITE_LOG \
-m $SQLITE_MAC \
-n $SQLITE_PLAYERNAME \
-s $SQLITE_LMSIP ; then
log_end_msg 0
else
log_end_msg 1
fi
}
--------------------
I tried messing with the PAM suff as suggested by JackOfAll in this

..adding this to /etc/security/limits.d/99-audio.conf:

This is what I'm now seeing for:

I'm in a over my head here and I don't really know how to interpret those
results. Does that look as it should? Anyway, the "popping" seems to
have abated. I don't have much content encoded at higher than redbook.
The one recording at 96kHz & 24 bit that I've got seems to play OK with no
strange artifacts that I can discern. I hate to declare success without
really knowing what I've done.
