Why is there no sound when playing music after Bluetooth is connected to the Buick LaCrosse?

If the Bluetooth is connected to the Buick LaCrosse but there is no sound when playing music, it may be because the car audio is muted or not switched to Bluetooth mode. Additional information is as follows: 1. Self-check: Confirm whether the issue is due to the mute state or the volume being turned down, resulting in no sound; play the radio to determine if the speakers are faulty; if the problem persists, you can visit a 4S store to identify the cause. 2. Buick LaCrosse: The main purpose of the Buick LaCrosse was to vertically replace the Buick Regal at that time, so its market positioning and pricing overlapped significantly with the old Regal. Similar to the previous generation Regal, the old LaCrosse also had pure American heritage, with its prototype being the American Buick LaCrosse.
I've encountered a similar issue where Bluetooth shows as connected but there's no sound. First, check your phone's volume—sometimes the media volume is set too low or mute is enabled. Then, see if the car stereo's volume knob was accidentally turned down to the minimum. If neither is the problem, navigate to the audio settings on the infotainment screen; after Bluetooth connection, you may need to manually switch to the Bluetooth audio source channel—I helped a friend with their LaCrosse last week, and they got stuck at this step. Another possibility is a glitch in the car's system; try restarting it by long-pressing the infotainment power button, or delete and re-pair your phone's Bluetooth. Also, it's a good idea to turn off other Bluetooth devices in the car, like chargers, as they can interfere with the signal. If that doesn't work, check if the mute button on the right side of the steering wheel was accidentally pressed. If none of these solutions work, it might be necessary to visit a dealership to inspect the head unit module or speaker wiring.
