DESCRIPTION:
When playing Music over Bluetooth-Output you can hear that the sound-quality (Bitrate) seems to decrease often while playing. It sounds like you lower the Output-Samplingrate and can be detected in mid to high Frequencys that sound a little bit distorted.
While my old Sony Xperia X Compact with official SFOS suffers the same bug, the Community-Port of XZ2 Compact doesn’t had this bug.
This bug is indepentend from the connected Bluetooth-Audio. I can reproduce it with my Sony WF-C500 In-Ear-Speakers and with LG Media-NAV Evolution Car-Audio. Pressing Pause and Play fixed it for a small Time-Window. It seems to be triggered more often when the CPU or GPU is under heavy load.
The Distance from the Bluetooth-Audio-Device to the C2 doesn’t change, so i can sort out this as an issue.
