This is what the waveform looks like while recording: https://i.imgur.com/m6wwVxC.png

and BeSplit output is this

[00:00:00:000] +------- BeSplit -----

Which for some reason seems to get different bitrate/channels each time I do it.
What software do you use for your recordings? and what exact besplit command.

If you're getting anything other than "Channels Count: 5, Bitrate: 384kbps" it means that there is likely to be some resampling or sync issue happening. For some reason BeSplit only reports 5 channels, even thought it's really 6. My advice is to go in and change some of the settings in your M-Audio control panel before recording. I've found that changing settings and the returning to the correct format right before recording can help fix sync issues with my M-Audio card.

You can also use bsconvert.exe (here: 🔍http://www.ac3filter.net/wiki/AC3Filter_tools#bsconvert) to get your ac3 stream unpacked. I like it because it's less typing. ex:

bsconvert input.wav output.ac3
