“Audio device buffer underflowed. If this occurs frequently, try decreasing the H/W Buffer Size in the Playback Engine or remove other Firewire devices (-6085 or -6086)” during playback in Pro Tools LE 7.1.1. Article #30958; Updated on Apr 27, 2007 at 12:00 AM
Avoiding Buffer Overflows and Underflows
https://developer.apple.com/library/archive/documentation/Security/Conceptual/SecureCodingGuide/Articles/BufferOverflows.html
Fundamentally, buffer underflows occur when two parts of your code disagree about the size of a buffer or the data in that buffer. For example, a fixed-length C string variable might have room for 256 bytes, but might contain a string that is only 12 bytes long.

[01-18 01:28:44] Audio buffer underflow, decoding thread blocked, encoding thread to exit. [AudioEncodeThread] And the resulting video has just a few seconds of audio, and then the audio is cut off, and there's silence from this point on. The video image is fine. The same thing happens either with the FAAC audio converter or with FFMpeg.

The Error Message. The audio device buffer underflowed. If this occurs frequently, try decreasing the “H/W Buffer Size” in the Playback Engine panel or remove other devices from the audio firewire bus. (-6085) Occasionally this error pops up in Pro Tools, usually after I return from a meal in the middle of a long recording or mixing session.

Show activity on this post. I have implemented a simple Qt program based on the example in the QAudioOutput documentation here. The program plays raw audio from a file using QAudioOutput when I press a button. The audio plays fine but I receive Got a buffer underflow! at the end of the file before QAudioOutput changes to the idle state.

However, buffer underflows can be an issue with e.g. ring buffers. Consider for example audio playback: your audio buffer is probably a ring buffer somewhere in kernel memory. If you write data slower than the audio driver/hardware reads from the buffer, the buffer becomes empty ("underflows"), leading to stuttering audio.
