Hello,
After using Squeezelite and some form airplay emulation in different setups, I decied a couple of days ago to try out Max2Play. Love it.
But: I cannot use Squeezelite and Shairport together on the Hifiberry Amp on my Pi B. As long as the Squeezelite client is in „on“ power state, it blocks access to the soundcard for Shairport. Bummer.
Shairtunes would be a pain to install on Synology so I came up with this:My solution:
Use the telnet interface of Logitech Media Server (LMS) to switch of the client (not shut it down!!) as soon as the playback of Shairport starts. Shairport has special command line switch to achieve this ( -B, –on-start=PROGRAM -E, –on-stop=PROGRAM). As soon as the airplay stops, the squeezelite client is powered back on and the last playing state is restored.This script does the magic (relies on the netcat or nc command). Saved as /home/pi/script/sbc_switch.sh
#!/bin/bash ### Squeezebox switch LMSIP="lms.home" # LMS IP Address or hostname LMSPort=9090 # LMS Port SBC_MAC='00:0f:13:29:14:22' # Squeezebox Client MAC Address ### INIT shopt -s nocasematch echo "$1" if [ "$1" == "resume" ] ; then ### Resume SBC_PW=$(printf "${SBC_MAC} power 1\nexit\n" | nc $LMSIP $LMSPort 2>/dev/null | cut "-d " -f 3) SBC_LM=$(printf "${SBC_MAC} playerpref lastmode ?\nexit\n" | nc $LMSIP $LMSPort 2>/dev/null | cut "-d " -f 4) if [ "${SBC_LM}" == "play" ] ; then SBC_MO=$(printf "${SBC_MAC} mode play\nexit\n" | nc $LMSIP $LMSPort 2>/dev/null | cut "-d " -f 3) fi else ### Shutup SBC_MO=$(printf "${SBC_MAC} mode ?\nexit\n" | nc $LMSIP $LMSPort 2>/dev/null | cut "-d " -f 3) SBC_LM=$(printf "${SBC_MAC} playerpref lastmode ${SBC_MO}\nexit\n" | nc $LMSIP $LMSPort 2>/dev/null | cut "-d " -f 4) SBC_PW=$(printf "${SBC_MAC} power 0\nexit\n" | nc $LMSIP $LMSPort 2>/dev/null | cut "-d " -f 3) fiI altered the shairport startup script to add the command line switches:
SHAIRPORT_OPTIONS="--on-start /home/pi/script/sbc_switch.sh shutup --on-stop /home/pi/script/sbc_switch.sh resume"Then altered startup line:
/sbin/start-stop-daemon --start -b -m -p /opt/shairport/log/shairport.pid --chuid $USER --startas /bin/bash -- -c "exec /opt/shairport/shairport --name \"$NAME\" -o alsa -- $SHAIRPORT_PARAMETER > /tmp$
to
/sbin/start-stop-daemon --start -b -m -p /opt/shairport/log/shairport.pid --chuid $USER --startas /bin/bash -- -c "exec /opt/shairport/shairport --name \"$NAME\" -o alsa $SHAIRPORT_OPTIONS -- $SHAIRPORT_PARAMETER > /tmp$There is a little trick involved that stores the last playing state of the client in a custom variable „lastmode“ on the LMS itself. As soon as Shairports powers the squeezelite client back on, the last playing state is restored by reading that variable.
Thought I’d share this with you.
My server is running om port 9000, and you are right the CLI is running on port 9090.
I tried to use a „telnet 192.168.1.4 9090“ from my macmini (not the pi).
And then a power 0 command. The respone i got was : 00%3A04%3A20%3A28%3Ac5%3A26 power 0(just to se if the connection to the server was OK I also tried „player count ?“ and the responce was correct „player count 4“)
I also tried using the telnet from a MacBook to my MacMini. There is no firewall blocking.
