In most cases, this is normal. The LEDs react to changes in the audio signal—turning on when a signal changes (volume up/down, input switching, muting) and turning off five seconds after the signal stabilizes. Some connected devices may completely stop the signal during silent passages, causing the LEDs to turn off and then back on when audio resumes. This is intentional behavior. However, if blinking persists without audio output, verify your source device isn’t dropping the signal due to its own power-saving features.
