Octoprint and shairport-sync running at the same time

rknaub · January 2, 2019, 9:50pm

What is the problem?
If I run shairport-sync service, the octoprint web interface will not load, untill I stop the shairport-sync service. And vice versa as well.

What did you already try to solve it?
Reinstall shairport-sync, pkg update && pkg upgrade, rpi-update

Ironically, OctoPrint and ShairPort cannot share the same port. Looks like you can change the port that ShairPort uses in its configuration file:

github.com

mikebrady/shairport-sync/blob/50bb4a3c003be7b21b7d02abab923263104257d6/scripts/shairport-sync.conf#L19


//		You can use the following substitutions:
//				%h for the hostname,
//				%H for the Hostname (i.e. with first letter capitalised (ASCII only)),
//				%v for the version number, e.g. 3.0 and
//				%V for the full version string, e.g. 3.0-OpenSSL-Avahi-ALSA-soxr-metadata-sysconfdir:/etc
//		Overall length can not exceed 50 characters. Example: "Shairport Sync %v on %H".
//	password = "secret"; // leave this commented out if you don't want to require a password
//	interpolation = "basic"; // aka "stuffing". Default is "basic", alternative is "soxr". Use "soxr" only if you have a reasonably fast processor.
//	output_backend = "alsa"; // Run "shairport-sync -h" to get a list of all output_backends, e.g. "alsa", "pipe", "stdout". The default is the first one.
//	mdns_backend = "avahi"; // Run "shairport-sync -h" to get a list of all mdns_backends. The default is the first one.
//	port = 5000; // Listen for service requests on this port
//	udp_port_base = 6001; // start allocating UDP ports from this port number when needed
//	udp_port_range = 100; // look for free ports in this number of places, starting at the UDP port base. Allow at least 10, though only three are needed in a steady state.
//	drift_tolerance_in_seconds = 0.002; // allow a timing error of this number of seconds of drift away from exact synchronisation before attempting to correct it
//	resync_threshold_in_seconds = 0.050; // a synchronisation error greater than this number of seconds will cause resynchronisation; 0 disables it
//	ignore_volume_control = "no"; // set this to "yes" if you want the volume to be at 100% no matter what the source's volume control is set to.
//	volume_range_db = 60 ; // use this advanced setting to set the range, in dB, you want between the maximum volume and the minimum volume. Range is 30 to 150 dB. Leave it commented out to use mixer's native range.
//	volume_max_db = 0.0 ; // use this advanced setting, which must have a decimal point in it, to set the maximum volume, in dB, you wish to use.
//		The setting is for the hardware mixer, if chosen, or the software mixer otherwise. The value must be in the mixer's range (0.0 to -96.2 for the software mixer).
//		Leave it commented out to use mixer's maximum volume.
//	volume_control_profile = "standard" ; // use this advanced setting to specify how the airplay volume is transferred to the mixer volume.

Thank you! I changed that port to 5500 and removed the // before it, saved the file and restarted the shairport service and I have both services going now.

I'm very new to all this and am surprised I have gotten even this far. Hopefull what I did was correct and its not just a fluke!

Thank you again!

One and a half year later, I got a like on my post. This made me read my post and for a minute I could not figure out the irony. Ha, I crack me up...
