No "16bit 48000hz DVD" quality audio option for my Bluetooth connected speaker

I have a bluetooth connected speaker that stutters. It's default format is set to 2 channel 16 bit, 44100 Hz CD Quality and I can only switch it to 1 channel 16 bit, 44100 Hz. How can get my default format to switch to "16bit 48000hz DVD" quality for better audio and the stuttering to stop?

 

Audio formats for sound devices kept reverting to 16-bit 48000Hz (DVD Quality)

Recently I have started using my 3.5mm Jack headset plugged into an HDMI to VGA adapter which splitted the HDMI signal seperately into audio (3.5mm) and video (VGA) output. Before, I was using it directly onto the laptop's audio plug, which is recognised as Headphones (Realtek(R) Audio) by default.

I always use the highest format possible, which is the 24-bit, 48000Hz (Studio quality) for all my sound devices. However, when using this adapter, which is recognised as Intel(R) Display audio, it seems to keep reverting the settings back into 16-bit. 48000Hz (DVD quality) which sounds really bad. Despite applying the changes in the settings, it will constantly change when rebooting or running multiple audio from different apps at the same time. This problem does not occur when using either the default laptop speakers or the previous output above.

 

What is the difference between 16bit 48000hz with dvd quality and without dvd quality?



As the attached image,
when I plugged Yamaha pjp-20ur on my Windows 8.1 notebook,
the default format has two option:

• '16bit, 48000Hz' =>seems to be default
  
• '16bit, 48000Hz (DVD Quality)'
  

what is the difference between the two option?

the reason why I ask this question:

• first option: playing system test sound --> no sound
  
• second option: playing system test sound --> OK
  

and when I open webRTC sample page on chrome

sample page: getUserMedia: output device selection

and select Yamaha pjp-20ur

• first default format option: sound came out from the default playback
  
• second default format option: OK
  

so what's the difference between the two default format?
They have same bit depth and same sample rate, one option has note 'DVD quality' and another doesn't.
