Eliminating Airport Express Lag: Tips For A Smooth Connection

If you're experiencing audio lag when streaming from your Mac to a speaker connected to Airport Express, there are a few things you can try. Firstly, check if your Airport Express is configured to extend or join the wireless network provided by the Time Capsule. You could also try a wired connection between the Time Capsule and Airport Express. Another option is to use a third-party app, such as Rogue Amoeba's Airfoil, which can help eliminate lag by providing a better buffering cache for AirPlay streaming. Alternatively, you can try rolling back the firmware on the AirPort Express to 7.8 or 7.6.9.

Try a third-party app like Rogue Amoeba's Airfoil

If you're experiencing audio lag when streaming from your Mac to a speaker connected to Airport Express, there are a few things you can try. One option is to use a third-party app like Rogue Amoeba's Airfoil, which can help to eliminate the lag by providing a better buffering cache for AirPlay streaming. Airfoil has proven to be effective in reducing or eliminating the lag, which can be caused by audio buffering and the way the Express decrypts and decodes the AirPlay stream.

To use Airfoil, you'll need to download and install the app on your Mac. Once it's installed, open the app and follow the setup instructions. You may need to configure some settings, such as selecting the Airfoil speaker as your audio output device.

In addition to using Airfoil, there are a few other steps you can take to optimise your setup and potentially reduce lag. Firstly, check the firmware version of your AirPort Express. Rolling back the firmware to version 7.8 or 7.6.9 has been reported to help with audio lag. You can also try connecting your Time Capsule to your AirPort Express using a wired connection if they are located close enough together. This can help to improve the stability and speed of your network, reducing potential lag.

Another tool you can use to analyse your network is WiFi Explorer. This app can help you identify any issues with your network speed or configuration that may be contributing to the audio lag. By separating the 5GHz network and making the AirPort Express extend that instead, you may be able to improve the speed and performance of your devices.

Roll back the firmware on the AirPort Express to 7.8 or 7.6.9

Rolling back the firmware on the AirPort Express to 7.8 or 7.6.9 can help eliminate audio lag. This is because the Express decrypts and decodes the received AirPlay stream to an encoded digital audio (PCM) format, and then buffers it for up to 2 seconds before it outputs it. This process can cause a delay of 2 seconds when playing audio from a Mac, but only a 0.1 or 0.2-second delay when playing from an iPhone.

To roll back the firmware, you can try the following steps:

• Go to the AirPort Utility on your Mac.
• Hold down the "option" key while double-clicking on the AirPort Extreme.
• Check the speed at which your AirPort Express is connecting.
• If your AirPort Express is connecting at a slower speed than other devices, separate the 5GHz network and make the AirPort Express extend that instead.
• Download WiFi Explorer to analyse your WiFi network and make any necessary adjustments.
• Note the MAC addresses and see which one your device is connecting to.

It is important to note that rolling back the firmware may not completely eliminate the lag, and other factors such as the quality of the network connection and the Mac's graphics card can also contribute to audio lag. Additionally, some third-party apps like Rogue Amoeba's Airfoil can help improve buffering cache for AirPlay streaming and reduce lag.

Use a wired connection between the Time Capsule and AirPort Express

If you're experiencing lag with your AirPort Express, one option is to use a wired connection between the Time Capsule and AirPort Express. This can help to eliminate any potential issues with wireless connectivity, which could be causing the lag.

To do this, you'll need to ensure that the Express is located close enough to the Time Capsule to facilitate a wired connection. You can also try using a third-party app, like Rogue Amoeba's Airfoil, which can help to "remove" the lag by providing a better buffering cache for AirPlay streaming.

It's worth noting that a small amount of audio lag is normal with streaming to the AirPort Express due to audio buffering. The Express decrypts and decodes the received AirPlay stream, buffers it for up to 2 seconds, and then outputs it.

Additionally, you can try rolling back the firmware on the AirPort Express to version 7.8 or 7.6.9, as this has been reported to help with lag issues. You can also use tools like WiFi Explorer to analyse your WiFi network and identify any potential issues that could be causing the lag.

Use WiFi Explorer to analyse your WiFi network

One way to eliminate lag when using Airport Express is to use a third-party app, such as Rogue Amoeba's Airfoil, which provides a better buffering cache for AirPlay streaming. You could also try rolling back the firmware on the AirPort Express to 7.8 or 7.6.9.

If you are experiencing issues with your network speed, you can use WiFi Explorer to analyse your WiFi network. To do this, go into Airport Utility and hold down the option key while double-clicking on the Airport Extreme. You should then be able to see the speed at which your devices are connecting.

You can also make a note of the MAC addresses and see which one your device is connecting to. This will help you identify any issues with your network configuration.

Make the AirPort Express extend the 5GHZ network

To make the AirPort Express extend the 5GHZ network, you can separate the 5GHZ network and make the AirPort Express extend that instead. You can download WiFi Explorer to analyse your WiFi network.

You can also try a third-party app, like Rogue Amoeba's Airfoil, which provides a better buffering cache for AirPlay streaming. Another option is to roll back the firmware on the AirPort Express to 7.8 or 7.6.9.

If the Express is located close enough to the Time Capsule, you could try a wired connection between the two.
