Have you met issue when switch BT codec

Hi,
I have connected to NAIM Mu-so Qb 0243 using my OPPO Android phone through Bluetooth. When playing music, It was using the Bluetooth A2dp AAC codec. But when I switched to SBC codec through Android developer options, the connection between phone and Qb 0243 is break. And switch to AAC from SBC codec, the same issue happens.
I found a Huawei Phone and tried, the same issue exists.
Any help? Thanks very much.
