I am trying to export two mono audio tracks as a single interleaved file, but the resulting WAV files contain nothing but a short spike at the start then silence. I am using Elements 11 with a Behringer UMC404HD audio interface, in Windows 10. I have both the record enable and monitor deselected on each track I’m trying to export. My audio output bus is set to UMC ASIO Driver, stereo. I have attached screenshots of the output bus setup and the mixdown dialog window. Is there something I’m missing?
Are your locators set to the range of the recording?
As the moderator Steve suggested, most likely you don’t have your range set.
If it’s not that, are your tracks disabled, or part of a group track, with some strange routing?
I always select my range with the P hotkey to set locators to the range of all selected events.
Thanks, that was it! I’ll probably be back with more incredibly basic questions later 
I am having the same problem too! Wav file is silent 
The file is silent when I send it via Gmail. There is an error when I press play in Windows Media Player.
Here are the settings when I try to export audio. How do they need to be corrected??
I think windows media player cannot play 32bit float files, try exporting at 24bit.
