Channel position inaccuracy and error

I'm having great problems with getting the channel position. Download example. The value I get is too inaccurate to make scenery react to the music in the game because it jitters left and right. Also, the channel position value wraps before the sound restarts which makes the value go totally out of sync so much that it's just impossible to apply it in a useful way.

If this could be fixed soon by any chance, it'd be a great deal for me, because there's a really cool thing I want to do but can impossibly do if this doesn't work.

The topic is too old for me to edit but I have some new information. The jitter with the sample position only happens with vorbis, but the incorrect wrap at the first loop happens with wave files too. I'm desperate about the wrap problem because it's preventing me to work on my idea now that I have the time, but the first problem really needs to be fixed too.

I don't see any jittering or wrapping, what should it look like?

Example. Do you see that the bar starts over an entire second before the loop actually does? It means that on the second loop, the playback position is an entire second off what it's actually playing. The jitter should also be clearly visible although it doesn't happen every time I run the example.

I can clearly see the jitter and wrap issue on your video, but it doesn't do that for me - it works perfectly. Do you think maybe it is dependent on the sound card?

It probably is, but it needs to be fixed either way. My game cannot only work on some computers.

Sorry to resurrect this, but next week I intend to have a game jam session where this feature is required to work for a musical thing I want to try. I'm desperate to have a fix for this.

If this is just for a game jam, why don't you just use an extension like Onu, Audiere, etc.?

Yves is looking into the problem but he doesn't know yet if it will be easy to fix or if the fix can come quickly.
So sadly -- if you need the fix fast you might be better off trying an extension of shelving this idea.

It's just not for a game jam tho. I want to incorporate this into Knytt Underground which doesn't rely on extensions.

Perhaps you could just do the extension route for the jam, then wait for Yves to find the real solution afterwards, which you can put into Knytt Underground.

Maybe, will have to figure out which extension that is best for this.

Nifflas, Onu is pretty good and you can even get visualization data with it. Check this out:

Onu has some weird design decisions though, I'm not sure I'd like to build the sound playback of an entire game around it. Nor do I like combining audio extensions (e.g. Onu with MMF2's built in sound) if it means they open the audio device separately.
