My Omnibook is stuck binding the JB Flex to LE Audio instead of A2DP.

[mdk1234]

I cannot pass bluetooth audio to my JB Flex headphones to my Omnibook.   Pairing is fine, test audio under Settings>Sound works but any other audio source will not work. This headphone works elsewhere (iPhone, Thinkpad, Roku Streambar).  No matter what I do,  JB Flex still binds to “Connected audio” only.

According to my research,  the Omnibook is stuck binding the JB Flex to LE Audio instead of A2DP.   My ThinkPad and iPhone work because they negotiate A2DP correctly, while this Omnibook does not because the JB Flex → HP profile is corrupted.  I have done the following in an attempt to fix this issue:

• Full Bluetooth driver reinstalls
• Removal of all JB Flex device entries
• Clearing Windows Bluetooth caches
• Registry pairing key removal
• Full shutdown cycles
• Forced A2DP profile reload attempts
• Headset‑side resets
• Cross‑device validation
• Final diagnosis (per‑device A2DP profile corruption)
• Bluetooth drive update

Hi @mdk1234 

Welcome to the HP Support Community.

Thank you for posting your query.

I understand that your JBL Flex headphones pair successfully with the HP OmniBook 7 16-ay0000 and work with the Windows sound test, but audio from other applications is not being transmitted. Since you have already reinstalled the Bluetooth drivers, removed and re-paired the headphones, cleared Bluetooth-related settings, reset the headset, and confirmed that it works with other devices, the issue appears to be isolated to the Bluetooth audio connection. I would request you to perform the following steps:

Open Settings

• Press the Windows key + I on your keyboard,
• Or click Start and select the gear-shaped Settings icon.

Go to Bluetooth & devices

• In the left sidebar of Settings, click "Bluetooth & devices."

Open DevicesOn the Bluetooth & devices page, 

• Click the "Devices" tile on the right side. 
• This opens a list of all paired devices.

Find the LE Audio toggle

• Scroll down to the "Device settings" section near the bottom of the Devices page. 
• Look for a toggle labeled "Use LE Audio when available.
• If you don't see it, your PC likely doesn't expose LE Audio support  skip to the Device Manager steps below to confirm.

Turn the toggle off

• If the toggle is On, click it to switch it Off. 
• This forces all Bluetooth audio devices on this PC to use Classic Audio (A2DP/HFP) instead of LE Audio.

Reconnect the JBL Flex

• Turn Bluetooth off and back on, or remove and re-pair the JBL Flex
• So it renegotiates its connection under the new setting. 
• Then try playing real audio (not just the test tone).

If no toggle appeared 

• Check Device ManagerRight-click the Start button and choose "Device Manager.
• Expand "Bluetooth," then find your Bluetooth radio (it may say "Intel Wireless Bluetooth," "Qualcomm," "MediaTek," or similar — not a specific headset name).

I hope this helps.

Take care and have an amazing day!
