When I listen to my local stored music with Android Auto connected via USB after a while the audio start jumping like a scratched CD.
I’ve tryed all the solutions I’ve found in the forum but none works for me.
I uploaded the logs after it happened.
The logs covers 4 months of data and many things after any playback.
Did that occurred near 8:30 today ?
If that’s the case the logs does not show any loading or issues on Symfonium side. This looks like the usual AA issues.
GPT answer:
That “scratched CD” stutter is almost always connection instability, phone power management, or a recent Android Auto / Maps / Waze bug that interrupts the audio stream.
Here’s the fastest way to isolate and fix it (USB Android Auto):
1) Eliminate the USB connection as the culprit (most common)
Swap the cable: use a short (≤1 m), good-quality data cable (USB-IF / reputable brand). Avoid “charge-only” cables and adapters.
Try a different USB port on the car (some ports are power-only or noisier).
Clean the phone’s USB-C port (lint can cause intermittent data contact).
If you use any USB extension / hub / angled adapter, remove it.
2) Remove phone-side throttling and background restrictions
Settings → Apps → Android Auto → Battery → set to Unrestricted (or “Not optimized”).
Do the same for your music app, Google Maps, and Google Play services (Play services can be the hidden limiter).
This “battery optimization” angle is a common fix path in troubleshooting guides. (Android Sage)
Also:
Turn Battery Saver off during drives.
If your phone overheats, it may throttle → stutter. Try removing the case or placing it in front of an air vent.
3) Update the “triangle” that often causes audio bugs
Update all of these (Play Store):
Android Auto
Google Maps (and/or Waze, if you use it)
Your music app
There have been waves of Android Auto stuttering reports tied to updates, often showing up “suddenly” after an app update. (9to5Google)
4) Quick reset that often clears the glitch
On your phone:
Settings → Apps → Android Auto → Storage → Clear cache (and if needed Clear storage/data)
Reboot the phone.
Google’s own community threads around “audio skips/cuts in & out” commonly start with (and sometimes get resolved by) cache/data clears + reconnect/re-pair. (Google Help)
5) Check the Bluetooth side even when you use USB
Many cars still keep a BT link for calls/metadata while AA runs over USB, and conflicts can happen.
In your car’s Bluetooth device list (your phone), try toggling Media audio off/on as a test (leave Phone calls on).
Some users have reported this stops the stutter even though AA is wired. (Cormang.com)
6) If it happens mainly when navigation is running
If the stutter appears only when Maps/Waze is open (especially during voice prompts):
Update Maps/Waze first (step 3).
Test with navigation closed for 5 minutes.
Recent reporting has linked stutter waves to navigation app behavior/updates. (Android Authority)
7) Car/head unit side
Check for a head unit firmware update (dealer update or OEM updater app/site).
If available: reset Android Auto / smartphone integration settings on the head unit and re-add the phone.
A 2-minute “diagnosis matrix”
Different cable → fixed? = hardware/data contact issue.
Unrestricted battery for AA + music app + Maps → fixed? = power management.
Stutters only with Maps/Waze → likely the current bug wave / app interaction. (Android Authority)
If you tell me your phone model + Android version + car model/head unit, and whether the stutter happens offline files vs streaming, I can narrow it down to the most likely 2–3 steps for your setup.
