Dell Latitude 5540 Intel Core i5-1345U Bluetooth Earbuds Cutting Out Fix
Dell Latitude 5540: Bluetooth Earbuds Cutting Out Fix
Root Causes
⚠
Wi-Fi 2.4 GHz and Bluetooth interference — both share the 2.4 GHz spectrum and cause mutual signal degradation on the Latitude 5540
⚠
Intel AX211 Bluetooth power management suspending the radio during Wi-Fi transmission bursts
⚠
Bluetooth audio codec negotiated at SBC (low quality) instead of aptX or AAC, causing worse coexistence with Wi-Fi
⚠
Earbuds battery low, causing weaker Bluetooth transmission power from the earbud side
Fixes
✓
Switch Wi-Fi to 5 GHz: In Network settings, connect to your router 5 GHz band instead of 2.4 GHz. The 5 GHz Wi-Fi band does not interfere with Bluetooth. This single change often completely resolves Bluetooth audio cutouts when using Wi-Fi and Bluetooth simultaneously on the Latitude 5540.
✓
Disable Bluetooth coexistence throttling: In Device Manager > Intel Wi-Fi 6E AX211 Properties > Advanced tab, find Bluetooth Collaboration or BT Coexistence and set it to Disabled. This prevents Wi-Fi from interrupting Bluetooth transmissions during high-throughput Wi-Fi sessions.
✓
Update Intel AX211 driver: Visit Dell Support and download the latest Intel Wi-Fi and Bluetooth driver for the Latitude 5540. The Wi-Fi and Bluetooth radio share the same driver package. Updates improve coexistence algorithms and fix audio dropout bugs specific to the AX211 on Core i5-1345U platforms.
✓
Check earbuds battery and keep within range: Low earbud battery reduces Bluetooth transmit power, increasing sensitivity to interference. Charge earbuds to full before use. Keep the Latitude 5540 within 1-2 meters of the earbuds — Bluetooth audio quality degrades with distance even when the connection remains technically active.
“My Latitude 5540 Bluetooth earbuds cut out every minute during Teams calls. Switching from 2.4 GHz to 5 GHz Wi-Fi resolved the dropouts instantly — Wi-Fi and Bluetooth were fighting over the same frequency.” — Rasyidah Nordin, senior HR executive

Why do Bluetooth earbuds cut out on the Dell Latitude 5540?
The most common cause is Wi-Fi 2.4 GHz and Bluetooth interference. Both use the same 2.4 GHz spectrum, and heavy Wi-Fi traffic causes Bluetooth audio dropouts. Switch Wi-Fi to 5 GHz to eliminate the interference. Also update the Intel AX211 driver from Dell Support and disable Bluetooth coexistence throttling in the adapter advanced settings.
What Bluetooth version does the Dell Latitude 5540 support?
The Dell Latitude 5540 with Intel Core i5-1345U supports Bluetooth 5.3 via the Intel Wi-Fi 6E AX211 combo adapter. Bluetooth 5.3 provides improved connection reliability, better multi-device handling, and enhanced LE Audio support for compatible earbuds compared to previous Bluetooth versions.
Can I pair multiple Bluetooth devices at once on the Dell Latitude 5540?
The Latitude 5540 can have multiple Bluetooth devices paired (remembered) simultaneously, but only one audio output device can be the active default at a time. You can switch between paired Bluetooth audio devices by selecting them in Sound settings. Non-audio Bluetooth peripherals like a mouse or keyboard can connect simultaneously with Bluetooth audio.
Does the Dell Latitude 5540 support aptX Bluetooth audio codec?
Support for aptX depends on the version of the Intel AX211 firmware and the Bluetooth audio stack. Windows 11 natively supports only SBC and AAC Bluetooth audio codecs. For aptX or LDAC support, the earbuds must negotiate a supported codec. The Intel AX211 Bluetooth stack in Windows 11 primarily uses SBC unless a higher-quality codec is supported by both devices.
