Airfoil update broke the plugin?

[philc]

Just processed an update to Airfoil to v4.8.12...and now Airfoil doesn't work.

Here's what I get in the log:

Enabling plugin "Airfoil 1.1.7"
Starting plugin "Airfoil 1.1.7" (pid 660)

Airfoil Error Update failed. Check to see if Airfoil is functioning correctly.

Disabling plugin "Airfoil 1.1.7"
Stopping plugin "Airfoil 1.1.7" (pid 660)
Stopped plugin "Airfoil 1.1.7"

That's me starting and stopping the plugin manually, but the log just fills with the update failed message until I disable the plugin.

Sorry to hit you with this on Christmas Eve...all the best guys, and please don't bother to work on this until after Christmas.

I'll take a look at this next week.

Reboot did the trick for me - Airfoil now working as before

I tried that...no joy

Here's a debug log of the problem, looks like one of my speakers (Master Bedroom) is all of a sudden a problem:

Same error here...

[philc]

BTW, I reset the speaker list and now the plugin shows no speakers found in the log.

Same issue here. The update broke the plugin.

Well, good and bad news: the good news is that it isn't a problem with the plugin. The bad news is that it appears to be a bug in Airfoil. If you try to get a speaker by it's ID in any AppleScript editor:

Code: Select all

tell application "Airfoil"
    speaker whose id is "INSERTIDHERE"
end tell

You get an OS error returned (-1728). It seems to work with the local speaker whose ID is "com.rogueamoeba.airfoil.LocalSpeaker", it's just any other speaker that is failing.

I've reported this to Rogue Amoeba and hopefully will hear something back from them in the next day or two.

New update for airfoil dropped recently... hopefully this was the fix.

No dice for me. This all started when Airfoil updated recently. I'm running the latest version of Airfoil and Instant On.

Hi Jay, it seems that the following statement works:

Code: Select all

tell application "Airfoil"
	get every speaker whose bonjourName is "INSERTIDHERE" --i.ex. "90840DEB89CE@Speaker" --
end tell

Unfortunately I don't believe it's possible to construct that particular series of apple events using appscript, which is what the plugin uses to communicate from Python to AppleScript. I'm hoping Rogue Amoeba will fix the problem since I'm not sure there's going to be another way to fix the plugin.

OK due to my absolute requirement that airfoil work for me at all times, I coded this. Feel free to use/modify this in any way.

I threw this in a file called airfoil.py

It requires the (no longer supported) python library "app script": http://appscript.sourceforge.net

Code: Select all

#!/usr/bin/python

from appscript import app

def connectToSpeaker(speaker):
        app(u'Airfoil').speakers[speaker].connect_to()

def disconnectFromSpeaker(speaker):
        app(u'Airfoil').speakers[speaker].disconnect_from()

def connectToAllSpeakers():
        app(u'Airfoil').speakers.connect_to()

def disconnectFromAllSpeakers():
        app(u'Airfoil').speakers.disconnect_from()

usage:

Code: Select all

import airfoil
airfoil.connectToSpeaker("Living Room")
airfoil.disconnectFromSpeaker("Master Bedroom") # or whatever your speakers are named

Hopefully the plugin's issues get resolved soon, but this is a decent stop gap.

I'll add more functions to change sources etc as time permits in the next few days. I just leave my input on "System Audio" so I don't need to change sources.

Great news! Rogue Amoeba has found the problem and corrected it in their latest developer release - 4.8.13d1 which can be downloaded here. If they've released 4.8.13 then you should already be covered.

There were actually two issues with this release - one was a bug which they fixed and another is a change in how speaker IDs are constructed. The latter required a change to the plugin, which will be included in the next general release of Indigo (6.0.21). You can download the updated Airfoil plugin v1.1.8 here in the meantime.
