Play sound from laptop to MMI 3G+

[Tgdc1978]

Hi. I have a 2023 A5 Sportback. It appears not to have an AUX input, only Bluetooth. I want to be able to play sound from a laptop so I can use an audio calibration app that plays a tone sweep and measures the frequency response. But I'm having trouble syncing a laptop to play via Bluetooth (and even if that worked the sound would be compressed by the Bluetooth codecs). Is there a way to use an external laptop as an audio source via ISB or some other way? Thanks

I realize a misnamed the system in the thread name. I believe the one I have is MIB3.
