Re: No audio output bose companion 2 III

Hi 999, 


Thanks for reaching out! 


I'm sorry to hear you're having issues hearing audio from your Companion speakers.


Do you experience the same issue if you try AUX IN instead of FROM COMPUTER? 


As the speakers work with other devices, this problem can be isolated to the computer, not the speakers so there are a few things you may want to try. 


1. The speakers are connected to your systems audio card, so it will need to be set as the default audio source.



Click the speaker icon in the taskbar



Click the playback device arrow above the volume bar

(on my PC, it's "Realtek Audio", but this depends on the audio card provider on your computer)


2.  If you're using a PC tower, your speakers may be connected via the green output on the back of the computer, but did you know the Headphones outputs work in the same manner? Try connecting the system via the headphone ports to see if you get sound.


3. Do you have a set of headphones you could test with the computer? Do you get audio with them? If not, try reinstalling the sound card's drivers. Go to Device Manager and reinstall the drivers for it. There is a Microsoft article with a full list of troubleshooting steps you can perform to remedy sound issues here.


I really hope this helps! Please let me know how you get on!
