In case of a buffer underrun the read index is equal or larger than the write index. Unless the prebuf value is 0, PulseAudio will temporarily pause playback in such a case, and wait until the buffer is filled up to prebuf bytes again. If prebuf is 0, the read index may be larger than the write index, in which case silence is played.

Should underrun occur, the read index of the output buffer overtakes the write index, and hence the fill level of the buffer is negative. Start of playback can be forced using pa_stream_trigger() even though the prebuffer size hasn't been reached. If a buffer underrun occurs ...

Posts: 1,570. Re: [SOLVED] ' (snd_pcm_recover) underrun occurred'. Pulseaudio has settings similar to alsas buffer_size, increase those. Refrain from using outside guides without understanding what you are actually doing, you probably should default your configuration for pulseaudio first, before attempting anything else.
