Can't select airport express

In order to stream audio, other than from iTunes, to an AirPort Express you would need a third-party solution, like Rogue Amoeba's Airfoil. Unfortunately, you cannot direct an AirPlay stream using the Sound option under System Preferences.

I have this exact problem, which is frustrating as I always used to be able to direct the sound output for my Mac (for Spotify use) to my Airport Express. Something must have changed in the Maverick OS release? Very frustrating, half the reason for getting an Airport Express in the first place!

I have the problem too. Turning wifi off and back on solves it for me.

You don't need third party applications anymore to be able to stream sound from your mac to an airplay device. It's build into OSX Mountain Lion and Mavericks. Just hold down Alt when clicking on the speaker icon in the menubar and choose your airplay device.

His profile says he is still running Tiger 10.4.11 on a MacBook

Not sure if he can upgrade or not unless he gives us more info.

Here is a screen shot of the Sound icon on the menu bar running Mavericks.

I can port my computer sound out to either the Apple TV or my Airport Express in the Living Room.

It's a bug that seems to pop up occasionally after waking the computer from Sleep. Either reboot or open a terminal windows and paste:

sudo kill `ps -ax | grep 'coreaudiod' | grep 'sbin' |awk '{print $1}'`

This is incorrect. I have been outputting all audio from my macbook to airport express regularly since mountain lion.

But also I sometimes have the same issue as OP.

This worked for me. Thanks for the information.

I have just had the same problem connecting to Airport Express from my MacBook Pro using Mavericks 10.9.1 (It has been working fine up till now) and could not be resolved by a reboot. The above has resolved the problem.

Thanks for the command line. Worked perfectly.

It works also for me. Thanks!

Command line worked for me too- thanks!

sudo kill `ps -ax | grep 'coreaudiod' | grep 'sbin' |awk '{print $1}'`

Worked for me too, Thanks!

Hi there, thanks for posting this. It worked really well until a couple of months back and since then it has suddenly stopped working.

This error message appears:

-bash: command substitution: line 1: unexpected EOF while looking for matching `''

-bash: command substitution: line 2: syntax error: unexpected end of file

usage: kill [-s signal_name] pid ...

kill -l [exit_status]

kill -signal_name pid ...

kill -signal_number pid ...

Any ideas what's going on?

Thanks!

Turning Wifi on and off just worked, (Thanks! areyouben) and is a very quick and easy fix if you don't want to open Terminal or don't have the command handy. Not sure if this will forever work, but just did for me!
