Bluetooth error, recognition, volume.

[mejigames]

I have Bluetooth headphones and sometimes my computer recognizes the headphones correctly but my headphones do not appear in the FXSound audio output.

Another problem is that the volume stops working out of nowhere, my computer shows the volume control (I can see how the bar goes up and down) but the volume itself does not really change.

I have tried formatting my headphones from the factory, I have deleted the connection in my Windows 11, I have tried modifying some parameters in the sound settings, I also saw that it said that the devices must be at 4800Hz and my headphones are indeed at 4800Hz, in short, I have tried several things and the only solution I have found so far is to restart my computer, only then does it work properly again.

I also clarify that this happens to me often because I leave my computer in hibernation, so there may be some conflict with that. I hope you can help me. Thank you.

Hi Meji, welcome to the forum.
Have you read the troubleshooting list at the top yet?
Which version of FxSound do you have installed? The latest release is v1.1.26.0 available from fxsound.com as always, and your version number is shown in the Help tab of the Settings menu.
I’ve compiled some further information below.

Have you checked all the volume settings in your system, e.g. the Volume Mixer, or the volume controls on your headphones themselves? Sometimes certain settings can override other settings.
The best fix reported on our forum for volume problems, would be EarTrumpet, or, alternatively, Volume², small free applications for volume control.

@bvijay

[…] We had given a suggestion to check the volume set in volume mixer and in some cases it worked because the volume was set to low in the system settings or for a specific application in the volume mixer. Can you go to the advanced options in System → Sound and check if the volume is set correctly for the device and volume mixer for system sound and the apps.

What brand and model are your headphones? Do they have the latest firmware and updates? And can you confirm that they are a stereo device, or set to stereo? FxSound does not support mono devices.
This is the main issue on Bluetooth,

Issues with Display Off / Standby / Sleep Mode

@doolhoofd

Multiple forum members have complained about issues with FxSound while the Display is Off or the machine is in Sleep Mode a.k.a. Standby Mode.

Description:
When the Display is turned Off or the computer goes into Sleep Mode,

1. Playback device is lost or switched;
2. The audio lags or glitches;
3. CPU/GPU/RAM usage intensifies;
4. Battery drain intensifies.

1. Playback device is lost or switched

Possible cause(s):
Usually due to lack of support for modern standby power states (S0 low-power idle).

Possible solution(s):

1. Disable all unneeded devices including hidden ones in Windows Sound Settings;
2. Disable automatic switching in the General tab of FxSound’s Settings - outdated since v1.1.26.0. Instead, look here for the full explanation on the new Preferred Output Device feature:
   https://forum.fxsound.com/t/preferred-output-device/3412
3. Change the Power settings to make the computer/display stay on longer;
4. Check if your computer supports modern standby power states (S0 low-power idle) by running this command:
   powercfg /a
5. This workaround suggested by forum member @metanoiance:

Using Notepad, I made a text file with the following lines, and saved it as .bat:
taskkill /f /im FxSound.exe
cd C:\Program Files\FxSound LLC\FxSound
start /min FxSound.exe
Then I used the default Windows Task Scheduler to run the file on wake-up. Meaning every time the PC wakes up from sleep or hibernation, the FxSound.exe will be restarted.
Note that the second line in the .bat file can differ depending on where you installed FxSound.

2. The audio lags or glitches

Possible cause(s):
HDMI monitor audio has proven to be prone to glitches, even without FxSound.

Possible solution(s):

1. See solution 1. above,
2. See solution 2. above,
3. Free up space on C:\ drive,
4. Install the latest Intel Rapid Storage Technology drivers (for Intel users),
5. Run a scan with LatencyMon for possible latency issues on the machine.
