When i connect my soundcore Q45 i don't hear anything and i don't know why i can not change the audio quality to the 2channel 48000 DVD quality. One time when i connected my headphones they automaticly switched to the dvd quality and i could hear stuff but now it goes in another quality that is not the DVD one i tried disinstalling the device updated driver and all that stuff (laptop=HP envy 360x 2-in-1 14-fc0xxx with windows11). Can you help me?

    Hello B-Burkhardt,

    It is possible that Windows is using a different Bluetooth audio profile for your Soundcore Q45, which may explain why the two-channel format is unavailable and no sound is produced.

    At this point, I recommend that you review and try the steps provided in the AI generated answer on your thread. That reply typically include the most relevant checks for this scenario. 

    Please close any apps that may be using the headset microphone, such as Teams, Discord, or browser calling apps. Then go to Settings > System > Sound and make sure the Soundcore Q45 is selected under Output.

    Could you also confirm:

    • Do you see more than one Soundcore Q45 option in the output device list? If so, which one is selected?
    • Does the headset produce sound when connected to a phone or another computer?
    • Does the issue occur in every app or only in a specific one?

    If the headset works correctly on another device, please install the latest Bluetooth and audio drivers for your exact laptop model directly from HP Support, as Device Manager may not always provide the manufacturer-specific driver.

    Since reinstalling the device and updating drivers were already tried, focus on the output format and pairing path that matches this symptom:

    1. Check that the headphones are the active output device.
      • Click the Sound icon on the taskbar.
      • Make sure the soundcore Q45 is selected.
      • Or go to Start > Settings > System > Sound and under Choose your output device, select the Bluetooth headphones.
    2. Turn off Mono audio.
      • Go to Start > Settings > System > Sound.
      • In the Output section, turn off Mono audio.
      • Mono audio can interfere with stereo playback.
    3. Try setting the format again from the device sound properties.
      • Right-click the Sound icon in the taskbar and select Sounds.
      • Open the Playback tab.
      • Select the Bluetooth headphones and choose Properties.
      • Open the Advanced tab.
      • Under Default Format, select 2 channel, 16 bit, 48000 Hz (DVD Quality).
      • Click Apply, then OK.
    4. If that format is not available or does not stay selected, re-pair the headphones.
      • Go to Start > Settings > Bluetooth & devices > Devices.
      • Find the headphones under Audio.
      • Select Disconnect and then Remove Device.
      • Put the headphones back into pairing mode.
      • Select Add device > Bluetooth and pair them again.
      • After reconnecting, return to Settings > System > Sound and check whether Format now shows 2 channels, 16bit, 48000Hz (DVD Quality).
    5. Update the Bluetooth adapter driver again from Device Manager, then restart.
      • Go to Start > Device Manager.
      • Expand Bluetooth.
      • Right-click the Bluetooth adapter and select Update driver > Search automatically for updated driver software.
      • Restart the PC if prompted.
    6. Check for Windows updates.
      • Go to Start > Settings > Windows Update.
      • Select Check for updates and install anything available.
    7. If audio still fails, test with another Bluetooth headset or speaker.
      • If another device works in stereo, the issue is likely with the original headset pairing or device behavior.
      • If all Bluetooth audio devices fail, the problem is more likely on the PC side.
    8. Confirm the headset supports A2DP audio streaming.
      • Windows uses A2DP for higher-quality Bluetooth audio playback. If the device is not using that path correctly, sound may fail or quality options may be limited.

    On Windows 11 with Bluetooth LE Audio devices, there is also a separate setting that can affect stereo behavior while the microphone is active:

    • Go to Settings > System > Sound.
    • Select the Bluetooth LE Audio device under Output.
    • Expand Output settings > Format.
    • If Format when microphone is active appears, select Stereo (2 channels).
    • If that setting is missing, install the latest OS and driver updates.

    If stereo audio becomes glitchy or drops when the microphone is active, switching that specific setting to Mono (1 channel) can improve compatibility.
