--- Comment #9 from Niklas Haas <bugs.freedesktop at haasn.xyz> ---
I did another test, this I changed the way mpv resets the stream. When
continuing playback, I varied the pa_seek_mode used for the first
pa_stream_write invocation  after a reset.

My results were as follows:

RELATIVE: already observed, upwards discontinuity
ABSOLUTE: completely explodes (massive, 2 second spikes)
RELATIVE_ON_READ: small downwards blip in latency, ao-dev jumps by about 30ms.
(attached)
RELATIVE_END: similar to RELATIVE_ON_READ

It's possible that using RELATIVE_ON_READ after a flush could alleviate this
issue somewhat. Advice from somebody who knows more about the PulseAudio API
and codebase is appreciated.
