Well, I think jmc47 could give us some help opening a pr and start some investigation

PRs are created after investigating and finding a solution, not before.
Sorry, my bad. I though they were to start talking about a bug.
We have an open bug report. Your best chance to getting it fixed would be to get Julian Loehr interested in the project

I am interested in the issue and would like to do some research. Currently i simply don't have any spare time for it

I have succeeded then. I'm 99% sure that the bug will still be there when you have spare time

Nice to know @JulianLoehr
If we can help with testing when you get time to do some research, let us know
@JMC47 get ready to test some shi**y speaker games when fix comes.
Do we have a link to the already open bug report? To see what were discussing

There's an old bug report if you search our bug tracker. If you wanna ping it and say you're available for testing, feel free. Just don't expect any immediate progress.

Thanks JMC, seems a really old bug report. Even were discussed the bt stacks and bt dongle as possible causes, that many years later were proven wrong.
But, probably doesnt need a new bug tracker ticket.
Since wiimote speaker lags more and more as many sounds are sent, I wonder if there is something wrong with the bitrate of the audio sent, I read wiimote audio capabilities has 2 different codecs or bitrates.
