Unet Audio closed unexpectedly

patel999jay commented 2 years ago

I am trying to transmit my baseband signal using unet audio but it closes everytime unexpectedly. I am pretty sure the size of the baseband signal is not exceeding the MaxLength.

Here are some logs if that would be useful.

free(): invalid size

I am not sure which invalid size the logs were referring to ? I am attaching the bb_signal.txt for reference as well. bb_signal.txt log-0.txt

Thanks @patel999jay.

free(): invalid size makes me think it's something in the physical layer implementation. Let me look at this in detail.

notthetup commented 2 years ago

@patel999jay Its seems from the logs you're running Linux. If so which version?

patel999jay commented 2 years ago

@notthetup : you're correct I am running Ubuntu. Below are the details of the same.
