Hi, I just upgraded to Ubuntu 20.04 LTS (from 18.04 LTS) and I now have an issue running replay_samples_from_file (using UHD-3.15.LTS with an N310). It now hangs "Waiting for recording to complete...". I did not have this issue prior to upgrade. I'm wondering if anyone else has seen this or if anyone has successfully run this example under 20.04?
I added some debug statements within the relevant while loop and determined that the Fullness is always 32592 / 32768 (32768 is the byte length of my tx file which is attached). I do not know why the Fullness never reaches 32768. If you have Ubuntu 20.04 and a USRP that has a Replay block (such as default image for N310) and could try this example with the attached data file (see command line and output below), I'd appreciate it.
