iPad Help! Can't output sound over HDMI on iPad pro 2018

[bearmaster1]

I recently purchased a new to me iPad pro 2018 11". For some reason, when I connect a TV to the iPad pro using an aftermarket USB C HDMI adapter, no sound is output. Video is fine though.

The adapter is a cheap knockoff of the apple AV adapter with a USB A plug, power and 4k 30 HZ. However the adapter works fine with sound and video when connected to my 2020 MBP via HDMI.

Does the iPad pro require a special dongle, that the MacBook pro doesn't? Or is this a know iPad OS bug? Seems like other users might have problems too.

Should work, sounds like an incompatibility with the cable. I use this with my 2021 Pro with both a 4K monitor and 4K TV -

I can verify that it was the cable. I bought a similar cable on Amazon that is hdmi to usb c only and it works fine.

Great to hear. Pun intended.

I assume it’s stereo only output not surround sound right?
