Stream music directly in lc3 from server to IoT device with nrf 9161 and nrf 5340

Hi

We are developing a small 30x30 mm iot device to stream music and voice commands from server to earbuds via bluetooth.

Can we stream lc3 or wav in 345 kbit with the nrf9161 ? Or must it be lower ? Is it same download for the nrf9160 ? 

Is there other bluetooth chips than nrf5340 that has lc3 codec or other codecs ?
