Hi there @Ecohen129.

Thanks for reaching out, we’d be glad to help.

All of our home theater products, including Arc, were designed to be used with TVs. We don’t recommend using a third-party device to get the audio from multiple sources prior to it getting to the TV.

Your query can be best answered by those who have the same setup, and hopefully, someone who does will stop by and be able to help you.

In addition, some of the community members might provide their own opinion about this anytime soon.

If you have any other questions, feel free to reach out.
