Bluetooth speaker (Lenovo 500) is connecting with laptop but sound is not coming

Hi Team,

I am having Lenovo Yoga 500 laptop which i use it to connect to my bluetooth stereo speaker Lenovo 500. My laptop is running the latest version of Windows 10 (last updated on 13-Jan-2016). It was working fine before last Nov 2015 big OS update.

After that (i checked it only this year), it is pairing and staying connected but the sound is not coming. Strangely the laptops speakers is also in sync with bluetooth speakers and even then no sound. Also i cannot hear the sound from the laptop speakers
when it is connected to a bluetooth speakers. Laptop speakers works well when it is not paired.

However the same bluetooth speaker is working perfectly fine with my Lumia 920 running WP 8.1.

Kindly provide your suggestions or solutions for this.

Thanks

 

USB sound/midi device not recognized

I have a Technics PR804 keyboard attached to my Windows 10 laptop through USB. I've installed the drivers that came with my keyboard by entering compatibility mode to Windows ME, but the device manager won't recognize the hardware when it's turned on and
plugged into my laptop. I've seen instructions online indicating that device manager should identify the keyboard as a sound device, and that I should be able to choose folder location for correct driver, but can't complete this step as device manager does
not list the keyboard as an available device.

Any suggestions?

Considering the audio troubleshooter you might try more options e.g. at step 3
