Topic: HDSPe MADI on Linux, doesn't get enough sample
I'm using HDSPe MADI on Linux setup for recording streaming audio to wave file. It's serving it's basic purpose just fine, we are able to create audio wave recording in 1 hour chunks.
But now we discovered that we don't actually end up with exact 48 kHz sample per second. When you play the files that suppose to read as 1 hour, it only registers as, say, 59m 58s. We ran some tests and we found out that it's missing a few microseconds with each samples.
Any hint what could we be missing? I heard something about time synchronization, or even using external clocks. Could this be the case? Can you give some ideas what I can try?
Thanks a lot!
