LE Audio in Radxa Zero 3w

#1

I purchased the Radxa Zero 3W specifically to try out the LE Audio feature, which is supported at the hardware level by Bluetooth 5.4.

I burned radxa-zero3_debian_bullseye_xfce_b6.img into it, and found that LE Audio is not working. And it’s because CONIFG_BT_ISO is not enabled or not supported by the current kernel version 5.10.160-26-rk356x.

I executed this script:

if grep -q "CONFIG_BT_ISO=y" /boot/config-$(uname -r); then
    echo "ISO support is built into the kernel"
elif grep -q "CONFIG_BT_ISO=m" /boot/config-$(uname -r); then
    echo "ISO support is available as a module"
else
    echo "ISO support is not present"
fi

I am new to the embedded field, and so I asked AI, and it gave a suggestion that the latest kernel has full support for LE Audio, and you have to enable the crucial config for LE Audio, while building using CONFIG_BT_ISO=y.

  1. First, I want to get feedback or suggestions from, who have already tried LE audio in the Radxa Zero3 W board.
  2. Second, does anyone have very latest image with full Bluetooth support enabled?
