MacFarlane, who has been the CEO since the company started in 2002, will also step down from the Sonos board. He will be replaced by Patrick Spence, another longtime Sonos executive.
MacFarlane will remain an employee at Sonos, he told the Times.
Sonos is a private company and doesn't disclose sales or revenue figures. But the company did lay off several workers in March 2016 and refocused on building devices compatible with voice controls, similar to what you see with the Amazon Echo or Google Home.
The company's chief product officer also left in March 2016.
Sonos didn't announce any major new hardware products in 2016, but it did say it partnered with Amazon to integrate Sonos speakers with the Amazon Echo and Echo Dot. That integration is supposed to go live early this year.
