Is my Omni s6 a brick after update?

I tried to put on some dinner music this evening, and the Polk Omni app told me I needed to update my S6. This has not gone well. Over the last four hours, I have cleared data, cleared cache, reinstalled apps, manually updated via USB, downloaded the PC app, done web browser setup, restarted every device a dozen times, and done a factory reset on my router.

My Omni S6 has not made a sound since I clicked update. There are no beeps. While I can see the device in Spotify, and the buttons and lights indicate music is playing, there is no sound. I plugged my phone in directly via 3.5mm cable, still no sound.

I have been unable to find anything in the support documentation, and the Omni app still tells me I need to update, then proceed to fail after 15-30 seconds. Is this now a $300 paperweight, or is there something else I can do?
