Audio Buffer Underrun. - FamiTracker
http://forums.famitracker.com/viewtopic.php?t=1577
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).

Okay, so every time I open FamiTracker, down at the bottom on the Status Bar, it says: "Audio buffer underrun, sound settings may be too high for this system or CPU utilization is too high." And every time I play or enter notes, there is a short skip/click type of thing every second or so, at regular intervals regardless of when I press play or enter the note.

Just to add a few more details, FT 0.4.6 experiences underruns every few seconds while playing a song with a buffer length of 40-80ms, and occasionally at 240ms (works almost perfectly here), while 0.5.0 beta 5 refuses to work fine at all (it has constant underruns no matter the buffer length).
c - USB Audio Buffer Underrun - Stack Overflow
https://stackoverflow.com/questions/46432862/usb-audio-buffer-underrun
So there is no chance for underrun. You simply send lesser number of samples to the host when the buffer being read was not fully filled before and it is host's task to deal with clock drift and resampling in whichever suitable way. You could worry about overrun on the other hand. If SOF frequency would be too low compared to ADC's sample rate, you could fill whole …

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.

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.
Problem with buffer underruns and audio dropouts …
https://www.reddit.com/r/RTLSDR/comments/se9vg/problem_with_buffer_underruns_and_audio_dropouts/
(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%.
Videos slow w/ stuttering audio - buffer underrun
https://forum.kodi.tv/showthread.php?tid=124883
Some of my files are stuttering. The video appears in slow motion while the audio repeats itself, progressing slightly forward each time. I can see there is an audio "buffer underrun" in the log file (below). This file is hosted on a local drive. My CPU and RAM are barely being consumed during this time.
