Hey NDS, welcome to the forums!
Could you please send me a link to the product you have as we do not sell a SoundTouch 700?
Thank you very much for confirming this for us.
Can you please try removing and re-adding the Google Assistant from your Soundbar 700?
I would also suggest rebooting the soundbar by unplugging from the mains for 30 seconds then re-applying to power.
Do let us know if this shows any improvements.
That's quite strange to hear! Do you notice any distortion in the audio when you play music through the soundbar? Or does this simply only happen when using the Google Assistant?
Thanks for getting back in touch.
Have you tried using Alexa instead to see if the same issue occurs?
Thanks for your reply.
The suggestion wasn't meant as a solution, merely as a means for testing to see if the issue persists via other services.
