Mirror OS X sound on Android without WiFi?

The audio jack hole on my Mac is broken. My Android phone's hotspot is my Internet connection, and I don't have any other WiFi. Is there any way I can have the phone mirror the sound of my Mac? I have already tried Bluetooth, but I use several other Bluetooth devices at the same time, and the Bluetooth sound gets a significant delay after some time. I work with creating subtitles for movies, and therefore that time delay is unacceptable to me. Please note that many of the apps that do this require a WiFi hosted by a third device (router.) I don't have that, and need to do it without it. I know this is technically doable, because when I host a hotspot and connect the Mac to it, an app called AirDroid works fine (without using any cellular data) with a transfer speed of 5 megabytes per second. I'm looking for exactly that kind of connection being used to mirror the Mac audio on the phone. I would even be interested in doing it with a USB cable. I'm interested in minimal delay and fair sound quality. The phone is a Samsung I9305 running rooted stock 4.4.4 with Xposed Framework installed. The Mac is running OS X 10.10.1. I would prefer not having to buy any new hardware.
