Why is my audio not playing through Bluetooth?

Check That Bluetooth Is Turned On

The first step in troubleshooting audio issues over Bluetooth is to ensure that Bluetooth is actually turned on for all your devices. On your phone, tablet, computer, Bluetooth speaker, or Bluetooth headphones, go into the Settings app and make sure Bluetooth is toggled on. Bluetooth needs to be enabled on both the transmitting device (phone, tablet, computer) and receiving device (speaker, headphones) for the audio connection to work properly.

According to the IEEE Spectrum, approximately 40% of mobile phones can be uniquely identified by their Bluetooth signals, meaning Bluetooth connectivity issues are common. If Bluetooth shows as ‘Off’ in Settings on any of your devices, tap the toggle to turn it ‘On’. You may need to wait a few seconds as it activates. Try playing audio again over Bluetooth. If the issue persists, you will need to move on to the next troubleshooting steps.

Ensure Devices Are Paired

One of the most common reasons that Bluetooth audio may not be playing is because the devices are not properly paired. Bluetooth devices must go through a pairing process before being able to connect and share data with each other (source: https://www.croma.com/unboxed/some-common-bluetooth-pairing-issues-and-how-to-fix-them). The pairing process establishes a secure, encrypted connection between the two devices.

To pair devices, start by ensuring Bluetooth is enabled on both devices. On mobile devices, this is usually in the Settings app. Then initiate pairing mode on both the source device (phone, computer, etc.) and receiving device (headphones, speaker, etc). This often involves pressing and holding a Bluetooth or Pairing button. The devices should detect each other and prompt to pair or connect. Confirm the pairing on both devices and they should now be connected.

If the devices will not pair, try rebooting both and restarting the pairing process. Ensure the devices are compatible – check manufacturer websites for supported devices. Devices may fail to pair if too far apart, so try moving them closer together. There are also advanced troubleshooting steps like clearing paired device lists and resetting network settings that can help resolve pairing issues.

Check That Devices Are In Range

Bluetooth has an effective range of about 30 feet in open space before signal strength starts to degrade, though the exact distance can vary greatly depending on the specific device models and environmental factors. Signals can be impacted by obstacles like walls and furniture that are between the Bluetooth transmitter and receiver.

If your devices will not connect, or the audio cuts in and out, it may simply be because the connected devices are too far apart or there are obstructions blocking the signal path. Try moving the devices closer together into the same room and within line of sight to improve connection reliability.

Some Bluetooth devices have lower powered transmitters and may only work over shorter distances of 10-15 feet. Check the product specifications to see the expected Bluetooth range. If your transmitter has a low range, you may need to position the devices closer to maintain a stable wireless audio connection.

Bluetooth standards like Bluetooth 5.0 introduce improved range capabilities, so newer device models may work over longer distances. But in general, 30 feet in open space can be considered the functional limit before Bluetooth audio performance starts to suffer.

If bringing devices closer together resolves any connection dropouts or skipping, then limited range is likely the issue. Try repositioning devices within closer proximity to take full advantage of the Bluetooth wireless range.

Update Bluetooth Drivers

Outdated or corrupted Bluetooth drivers can often cause issues with Bluetooth connectivity. Bluetooth drivers on your computer, phone, headphones, speakers, or other devices may need to be updated to the latest version in order to work properly. Keeping your drivers up to date ensures maximum compatibility between devices.

On Windows 10 and 11, you can update your Bluetooth drivers by going to Device Manager, locating the Bluetooth driver, right clicking it and selecting “Update driver.” You can also try updating your operating system or downloading the latest Bluetooth driver directly from the device manufacturer’s website [1]. On phones and tablets, checking for system updates in your device settings is the easiest way to update Bluetooth drivers.

Updating to the latest Bluetooth driver often resolves problems with connections dropping, audio stuttering, or devices not pairing correctly. Keeping drivers updated should be one of the first troubleshooting steps for any Bluetooth issue.

Reset Bluetooth

One of the most common solutions for audio not playing through Bluetooth is to reset the Bluetooth settings on your device. This clears out any problematic pairings or connections and gives you a fresh start (Source 1). Here are the steps for resetting Bluetooth on some common devices:

On Windows, open the Settings app and go to Devices > Bluetooth and other devices. Click the option to remove or forget all Bluetooth devices. Then toggle Bluetooth off and back on again. Restart your computer afterward for a full reset.

On Android, go to Settings > Connected devices > Bluetooth. Tap the settings icon and choose to forget all devices or reset. Then toggle Bluetooth off and on again. Restarting your phone completes the reset (Source 2).

For iPhones, open Settings > Bluetooth and tap the blue “i” icon next to My Devices. Select Forget This Device on all listed devices. Turn Bluetooth off and back on. Restart your iPhone to finish resetting.

Resetting Bluetooth along with restarting your devices forces them to re-pair and reconnect from scratch. This often resolves instability, lag, or playback issues if they are stemming from syncing problems between devices.

Check for Interference

Other wireless signals can disrupt Bluetooth connections and cause issues with audio playback. Devices like Wi-Fi routers, wireless keyboards/mice, microwaves, cordless phones, and other Bluetooth devices in close proximity can all potentially interfere with Bluetooth signals (1). Try turning off or moving any other wireless devices away from your Bluetooth audio device to see if that helps clear up the interference. Also make sure your Bluetooth device is within 30 feet and has a direct line of sight to the audio source to get the strongest signal (2). You may be able to minimize interference by moving the position of devices or placing Bluetooth transmitters closer to audio receivers.

Update Software

One potential cause of Bluetooth audio issues is outdated software on your devices. Bluetooth technology constantly evolves, and older operating systems may have bugs or lack compatibility with newer Bluetooth protocols. Updating your smartphone, computer, headphones, speakers, and any other connected devices to the latest OS versions can improve Bluetooth stability and performance.

For example, upgrading your iPhone or Android phone to the newest iOS or Android release may fix problems with audio streaming over Bluetooth. On computers, installing the latest updates for Windows, MacOS, ChromeOS, or Linux will ensure your OS has the newest Bluetooth drivers and compatibility fixes. The same applies for wireless earbuds, speakers, car systems, and more – updating their firmware to the latest available version can resolve software-related Bluetooth bugs.

Check the software update settings on each device and install any available updates. Then test if audio playback over Bluetooth is improved. Keeping your OS, drivers, apps, and firmware updated is key for enjoying a smooth and reliable Bluetooth experience.

Replace Bluetooth Adapter

A faulty or malfunctioning Bluetooth adapter can cause connectivity issues and audio problems. Bluetooth adapters can deteriorate over time or become damaged. Replacing the adapter may be necessary if it is determined to be defective.

Signs of a faulty Bluetooth adapter include frequent dropped connections, poor audio quality, inability to pair or recognize devices, and limited range. Troubleshooting steps like updating drivers, resetting the adapter, and trying different devices can help narrow down adapter issues.

If you’ve exhausted other troubleshooting options, purchasing a new Bluetooth adapter may be required. When selecting a replacement, check compatibility with your device and operating system. Consider options from reputable brands that offer strong connectivity. An adapter with the latest Bluetooth version (e.g. Bluetooth 5.0) will offer faster speeds and extended wireless range.

After installing the new adapter, pair your devices again and test connectivity across your typical usage. With a functioning adapter, your Bluetooth connectivity problems should be resolved. Just be sure to keep the adapter protected and avoid damage to maximize its lifespan.

Test With Different Devices

One way to troubleshoot Bluetooth connectivity issues is to test your devices with different Bluetooth peripherals. This helps determine if the problem lies with a specific paired device, or if it is a more general Bluetooth issue.

For example, if you are having problems getting your headphones to connect to your phone via Bluetooth, try pairing different Bluetooth headphones or speakers to your phone. If those devices connect properly, then the issue is likely with your original headphones, not your phone’s Bluetooth adapter.

However, if you test multiple different Bluetooth peripherals and none of them can establish a steady Bluetooth connection, then there may be an underlying issue with the Bluetooth capabilities of your device. This would point to a problem with your phone or computer’s Bluetooth drivers, hardware, or software.

Testing your device’s Bluetooth functionality with a variety of different peripherals is an important troubleshooting step that can isolate the cause of connectivity issues. If the problem persists across multiple devices, it indicates there is a deeper technical problem that needs addressing through driver updates, software updates, or even Bluetooth adapter replacement.
