How to connect more than 1 Output device at once?

[Evann]

Hi,

 

so currently i have 2 Output Devices connected to my PC (TV over HDMI and Headphones over 3.5mm jack)

 

Now i'd like to connect another  Soundbox to my PC (SONY SRS-ZR7), since i only have one 3.5mm jack, whats the best way to connect both to the PC?

 

Would this cable work? The Devices don't need to Output simultaniously, only one at the time.

 

if not, what else could i do? Do i need to buy a costly Soundcard / DAC?

 

Thanks in advance

Splitters like those work great. They can all be on at the same time, no issiues here.
