Connecting NanoPi Neo Air LTS to my Bluetooth Speakers

[friedonion]

Hey,

I am trying to use NanoPi Neo AIr LTS to play music on my bluetooth speakers/headphones.

I flashed debian bookworm, installed pulseaudio. I succcessfully paired the bluetooth with my headphones and tried playing mp3 files.
Although the music is playing, it is very noisy (lot of static noises), choppy and the audio quality is very bad.

I changed the buffer sizes, checked the sampling rates and tried different latency but nothing helped. Is this a hardware limitation? Is there any way to get good audio quality on my bluetooth speakers?

Thanks

Since the NanoPi Neo Air LTS has limited processing power, processing Bluetooth audio (especially with PulseAudio) can cause performance issues. Run the following command to check if the CPU is overloaded:

If CPU usage is high, try stopping unnecessary services or reducing other system loads. Bluetooth devices may connect in HSP/HFP, which results in very poor audio quality. Your headset needs to be A2DP
