Optional Patch for Orbit(TC580) - Fix "Crackling Noise" on aptX Low Latency Headphones – Avantree Support

Orbit (TC580): Optional Patch for Crackling Noise

Hearing crackling or popping sounds when using aptX Low Latency (aptX LL) headphones with your Avantree Orbit?

This optional firmware patch addresses the issue by prioritizing a different Bluetooth audio codec instead of aptX Low Latency.

Important: Contact Avantree Support Before Updating

Do not install this patch without consulting Avantree Support first.

An incorrect firmware update may render your device unusable. According to Avantree's firmware notice, device failure caused by an unauthorized or incorrectly performed DFU update is not covered by warranty.

You will also lose aptX Low Latency operation. After applying either patch, Orbit will prioritize FastStream or standard aptX instead of aptX LL. If you want to keep aptX LL, do not install this patch.
