Dear friend,Hi, just bought BTA30 and i'm having this problem
I pair my headphones with Aptx adaptive, the light indicator color turns violet after a second it turns into blue
whats happening? because i'm sure that the earphone im using which is Soundpeats Sonic is compatible to plain Aptx
also the volume is not adjustable on windows and the volume knob in BTA30 via usb in > TX mode
1. The BTA30 does not support APTX adaptive Bluetooth codec. You could try to switch the Bluetooth codec by double click the pair button to check again. And make sure that both device are not connecting to other devices at the same time.
2. Under the mode of USB in and Bluetooth out, the volume knob cannot work, and the LDAC codec is not supported. Because under this mode, the audio signal is not transmitted through the CT5302 chip which controls the volume. While the Bluetooth chip itself does not have the function of volume adjustment, so the volume knob on the device will be invalid at this time.
Best regards
