The issue you're experiencing with your Sonos Arc taking a long time to produce sound or not producing sound at all when changing channels is likely due to a communication issue between the TV and the soundbar. Here are several troubleshooting steps you can try to correct this problem: 1. Check HDMI-ARC/eARC Connection: Ensure Proper Connection: Make sure your Sonos Arc is connected to the TV’s HDMI-ARC or eARC port using the provided HDMI cable. The HDMI-ARC/eARC port on your TV is designed for audio return, and using the correct port is crucial for seamless audio performance. Re-seat the HDMI Cable: Unplug the HDMI cable from both the TV and the Sonos Arc, wait a few seconds, and then plug it back in. This can sometimes reset the connection and resolve the issue. 2. Update Firmware/Software: Update TV Firmware: Check if there is a firmware update available for your Sony TV and apply it if there is. Firmware updates can fix bugs and improve compatibility with connected devices. Update Sonos Firmware: Similarly, ensure that your Sonos Arc is running the latest firmware. You can check and update the firmware through the Sonos app. 3. Adjust Audio Settings on the TV: HDMI-CEC Settings: Ensure that HDMI-CEC (Consumer Electronics Control) is enabled on your Sony TV. This feature allows the TV and soundbar to communicate and synchronize properly. Audio Output Settings: Go to the TV’s audio settings and set the audio output to "Auto" or "Passthrough." Try switching the audio output format between different settings like PCM, Dolby Digital, and Auto to see if this resolves the delay. eARC Mode: If your TV supports eARC, make sure that eARC mode is enabled on both the TV and the Sonos Arc. 4. Check for Interference: Eliminate Possible Interference: Ensure that there are no other electronic devices nearby that might be interfering with the HDMI connection, such as routers, gaming consoles, or other HDMI devices. Try unplugging other HDMI devices from the TV temporarily to see if that resolves the issue. 5. Power Cycle the Devices: Restart TV and Sonos Arc: Turn off both the TV and the Sonos Arc, unplug them from the power source, wait for about a minute, and then plug them back in and turn them on. This can help reset the connection and fix any temporary glitches. 6. Test with Different Content: Channel or Input Testing: Test the Arc with different channels or inputs (e.g., streaming apps, Blu-ray player) to see if the issue is isolated to specific channels or content. This can help identify if the problem is related to certain audio formats or content types. 7. Check Audio Sync Settings: Adjust Lip Sync/Audio Delay: Some TVs have settings to adjust the audio delay or lip sync. Adjusting these settings might help synchronize the audio more quickly when changing channels. 8. Factory Reset (As a Last Resort): Factory Reset the TV and Sonos Arc: If all else fails, performing a factory reset on both the TV and the Sonos Arc might resolve any underlying issues. Be sure to back up any important settings before doing this. If the Problem Persists: If none of these steps resolve the issue, it might be worth contacting Sonos support or Sony support for further assistance, as there could be a more complex compatibility issue between the devices.
