Rendering Multi-channel audio with 'Export movie'

When rendering a video with Export movie, It seems like It actually cannot generate a file when I include CHOP with more than 2 channels or sample rate higher than 48000HZ

for example, if I want render a CHOP that is composed of 8 Channels/96000HZ sample rate, looks like it is rendering when I click the render button but Touchdesigner does not actually generate any .mov file no matter I use H.264 or Animation codec.

Is there any solution for this? I don’t want to use real-time rendering.

Thanks.

What audio codec are you using? MP3 only supports 2 channels
