I'm having a problem with bluetooth using RTL8723BE. I can connect to my wireless earphones, but when I play any media, the audio quality keeps fluctuating. If I move a bit, the quality degrades and sometimes even stops for few seconds.
Audio Configuration in Sound is High Fidelity Playback (A2DP Sink)
Things I tried:
- I tried the solutions mentioned in this post but while compiling, make throws 2 errors and I am unable to install.
- I tried re-installing Bluez but no difference.
- I tried installing Blueman which didn't work either.
Also, in Blueman, I get this when keeping my earphones next to my laptop:
Received Signal Strength: 30% (Sub-optimal)
Link Quality: 10%
Transmit Power Level: 50%
Bluetooth signal when earphones kept next to my laptop:
In Blueman, if I put the earphones 100-200 cm away from my laptop, I get this:
[Received Signal Strength: 28% (Poor)
Link Quality: 10%
Transmit Power Level: 50%]
Bluetooth signal when earphones are kept 100-200 cm away from my laptop:
