The Selected Proxy Does Not Support The Audio Error

[FutureTube5CF3]

Basically, I created a new proxy 

256×144

and I am getting the The Selected Proxy Does Not Support The Audio Error

It's quicktime proxy, can someone help me fix it, as i want the 256x144 dimensions.

Can someone create the proxy for me with that dimensions that works?

Your proxies need to have the same audio channels as the original. So if your original footage has 4 channels, the proxies' audio needs to match that.
