Simultaneously Pushing Audio to External Speakers and Bluetooth from a Mac

Standard

A couple of months ago I had the idea to see if there was a simple way to play iTunes music from the built-in iMac speakers while also playing it through a Bluetooth speaker (in this case a JBL speaker). My goal was to have the music playing from the computer in one room and also playing from a Bluetooth speaker in the dining room. Sure enough, OS X has a way to do this (I’m running 10.9 so I don’t know how widely this feature is supported across older versions of OS X).

Thanks to user Eric Ross in the Apple Support Communities I didn’t have to do much searching to find the answer. As detailed in his response, the solution is to open the Audio Midi Setup application located in the Utilities folder and then simply create a Multi-Output Device that has both speaker types selected. Note that in order for this to work the Bluetooth speaker needs to already be connected to the Mac.

MOD-Setup

At this point we’ve only created the multi-output device. One additional step is required – setting it as the current output device (System Preferences -> Sound -> Output) :

MOD-Select
I originally did this with my iMac but the screenshots in this post were created using my MacBook Air.

And that should work. The Bluetooth audio (at least with the settings I used) will have a slight delay in comparison to the system speakers. Bluetooth has a relatively short range so the practical applications of this method may be limited by obstructions within one’s home and the receiving capability of the Bluetooth device that is used.

 

Craftsman Lawn Tractor (917.289081) Won’t Crank/Turn Over

Standard

The Short Version: I had improperly routed a new belt, which damaged the brake safety switch. Re-routing the belt and replacing the switch will fix this problem. A new switch is relatively inexpensive. Photos and links are included in this post.

A few weeks ago I (incorrectly) replaced the drive belt on our Craftsman lawn tractor. My mistake, which I didn’t learn immediately, was to improperly route the belt through the front part of the mower. Instead of going to the right of the brake assembly I went to the left. This caused the belt to wear against part of the brake system. Unknown at the time, not only did this ruin the new belt but it also damaged the brake safety switch.
