Tell me more ×  I have my TV connected to my iMac via HDMI and
speakers hooked up to the iMac via the headphone port.  Whenever
I turn the TV on, the Mac starts playing audio through the TV
instead of the speakers and I have to manually switch back.  Is
there any way to make my Mac keep playing through the
headphonejack?  share|improve this question add comment  1
Answer  up vote 2 down vote accepted  I use a free app from
Rogue Amoeba called SoundSource that lets you quickly pick the
source for input, output and system sounds from the task bar.
One of the side effects of running SoundSource is your source
doesn't change when you connect something new to your Mac. You
have to select the new source explicitly via SoundSource to have
audio routed to or from it.  The source will switch
automatically if you remove a source and that source happened to
be the currently selected source for any of the channels.
