Windows 10: Changing Sample Rate Stopped Headset

Hello everyone. Today while I was looking through my speaker properties, I noticed I could change the Sample Rate (which I thought may give me better sound quality). However, after I changed it, the headphones I currently had plugged in stopped working. The speakers still work fine, and the headphones still work, and are recognized, they just don't produce any sound. I tried changing the sample rate back to the default 24bit 48000hz and restarting my computer but nothing seems to work. My problem is almost identical to this one: Headset stopped working after changing sample rate but I'm not sure where to find that option the second post refers to. Any help would be greatly appreciated. Thanks!

audiodp.exe and sample rate

I cannot change the sample rate in my recording interface because I get message that audiodp.exe is on and this will not allow sample rate change please advise

 

Horrible quality sound via bluetooth, It sounds like its stream is at a low bit rate so all the high frequencies create crackling distorted.

I bought nokia bluetooth headset NOKIA BH-111 ive connected it to my HTC HD7, and first thing ive noticed is horrible downgrade of sound quality via BT set, So contacted friend of mine, borrowed form him his sony-erricson bt stereo headset and same
thing occurs, I did some Bing research and found topic about this issue

Bad quality sound on Bluetooth Music streaming

the solution is only for unlocked phones using registry editor.

"[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Bluetooth\A2 DP\Settings]

"Bit Pool"= change Value data to 51.

As I suspected the problem was in the sample rate settings. After I did the hack it sounded beautiful and at full sample rate. Some people don’t have the ear to catch the difference. I like to think I have a very good ear for this sort of thing. Being
a musician and aspiring sound designer. I listen to all my music in the car through Bluetooth stereo gateway so I rely on this Bluetooth functionality 100%. Here is an example of the “Value data” number translated to sample rate.

Medium Quality

Bit Pool=35, Sample Rate=44.1 kHz = 229 kb/s

Bit Pool=33, Sample Rate=48 kHz = 237 kb/s

High Quality

Bit Pool=53, Sample Rate=44.1 kHz = 328 kb/s

Bit Pool=51, Sample Rate=48 kHz = 345 kb/s "

Also set "UseJointStereo" to 0 since one of the common joint stereo algorithm uses a lossy audio compression. BT Music sounds great with these changes!

Another thing is sound of keyboard not registering via BT, its muted and then 4-5 clics at very fast rate, whats up with this?

Looks like microsoft windows phone issue, what should i do to be able to use bluetooth stereo headset as intended without horrible HORRIBLE sound downgrade? and phone unlocking?
