What causes audio buffer underruns when CPU use is low ...
https://www.kvraudio.com/forum/viewtopic.php?t=447624
Underruns are mostly dependent on how os/kernel distributes cpu time between high priority tasks such as drivers/irq handlers. In my case HDD driver was doing about 50 ms latency while usb audio about 5 ms and other tasks were fairly low too. This caused random underruns even if cpu meter was low. Installing SSD solved this problem.

A longer buffer adds a slight delay to the sound while editing, though. It's best to leave the samplerate at your PC's native rate, which is probably 48,000 Hz (though some old devices prefer 44,100 Hz). Increasing it will only increase your CPU load, which is the cause of buffer underruns (CPU can't fill the sound buffer fast enough).

If the input channel discards input data or the output channel transmits silence, there are buffer underrun/overrun flags can be triggered, if XRBUF has not yet been written with new data since the last time the transfer occurred, the transmit state machine sets the XUNDRN flag and likewise, the receive state machince sets the ROVRRN flag.

Problem with buffer underruns and audio dropouts anyone ...

(this way the audio sound horrible, but for very narrow band signals would be still OK) What I observe when doing this is that the buffer runs empty (% value goes down) very slowly (around 40-50 seconds) and when it is empty the buffer underrun occurs with an audio dropout and a refill of the buffer to 50%.

Couple with this every channel I search through from 5000 upwards with the exception of the first 20 or so i get a message say Audio/video buffer underrun and therefore so service what so ever. Any ideas please? Im at a loss and thinking of sending the box back. It was set up with two inputs and is now on one.
Buffer underrun - Wikipedia
https://en.wikipedia.org/wiki/Buffer_underrun
In computing, buffer underrun or buffer underflow is a state occurring when a buffer used to communicate between two devices or processes is fed with data at a lower speed than the data is being read from it. The term is distinct from buffer overflow, a condition where a portion of memory being used as a buffer has a fixed size but is filled with more than that amount of …
