Hello,

I have the BTA30 connected via optical link to my Win10 desktop. The BTA30 connects to my Sony WH-1000XM4 using LDAC fine, but when audio from my PC plays, the BTA30 light changes from white to blue. The instruction guide says blue light is SBC. Is this a normal operation? Or should the light be white for LDAC the entire connection?

Dear friend,

Are you connecting the BTA30 to the computer via USB?

If yes, please read this FAQ for the reason:

Why is the LDAC transmitting not supported when connecting the BTA30 in USB input mode?
It resulted from our product location (cost control) and lack of awareness about the current market. Mainly, the USB input process of the BTA30 is handled by the CSR8675 chip yet without the LDAC transmitting codec provided by Sony. If the BTA30 is popular among consumers, we would consider an independent USB chip added in the future, such as the commonly-used XMOS chip.

In this way, the USB data would first be converted to I2S signals and later be transmitted to the 8675 chip, which supports LDAC transmitting.

As for the question of whether it would support the LDAC transmitting via USB-in in the future, we would like to say that if SONY supports us, we would definitely make it. Otherwise, it would be impossible. But nowadays, we just cannot assure it.

Best regards

Thank you for the assistance! That is exactly what the issue was. I had the BTA30 powered through a USB hub that was also connected to my PC. I connected the BTA30 to a separate power adapter and now it works with LDAC great!

Thank you for the help!
