Hello all. I am a developer of a game that utilizes a custom plugin in UE4 that implements the FMOD Core. We used version 1.06.09 (five years old) and so far we use it exclusively for streaming music from Soundcloud and calculating FFTs of these streams on the fly.
A problem we experience is that the Channel::setPosition causes the stream to seize playing/existing, after which Sound::getOpenState keeps returning HTTP access errors. Here is a log made using the logging version of FMOD. Note that I had to censor our Soundcloud client ID in the streaming URL.

I narrowed down the issue to that this only seems to happen when the position that the stream is set to is not yet buffered, because setting the position of the stream only slightly ahead results in an audible skip with resumed streaming, as expected. Similarly, we have received bug reports for our game that involve the stream also stopping in the middle of a track, which I assume also has to do with the stream reaching a point that is no longer buffered.
I then attempted to use the Sound::seekData function to buffer the part of the stream that we want the stream to skip to (assuming that is what this function does), but that also failed. This time with a socket error.

I found in the FMOD Core version history that the very next release had "Sound::seekData support for HTTP streams," so I felt an update was necessary and updated the FMOD Core straight to the latest version (2.01.06). The problem that arises now is that streams simply won’t start playing anymore, as it only throws HTTP access errors now, see the log below. Note that this also happens on the oldest available version of the FMOD Core (1.08.00), which is still newer than the one we were using before.

--- And so on ---
The code we use for streaming goes as follows. The stream is created using System->createStream(ANSIStream, FMOD_2D | FMOD_IGNORETAGS, 0, &SoundPlayback->Stream) with ANSIStream the stream URL and Soundplayback->Stream the Sound object. Next we poll System->playSound(SoundPlayback->Stream, nullptr, false, &SoundPlayback->Channel) with SoundPlayback->Channel the Channel object, until the sound can be played back over the Channel object (i.e. the function returns FMOD_OK).
In summary, I tried to use the Sound::setPosition function on version 1.06.09 on an HTTP stream, but that results in playback stopping completely. Updating to version 2.01.06 results in streams not even being able to start anymore.
I hope that someone will be able to help us figure out how to mitigate either of these issues, because we need to be able to set the stream positions.
