No that is an issue that needs to be resolved. The sound fx are mixed in software and played back in a single looping playback buffer. There are a couple issues. If the frame rate is too slow the mixing buffer gets behind. The second issue is that the synchronization timer drifts relative to the actually sound playback rate. There is currently no way to query the playback channel to verify position. The music is being played back in a separate thread and it mixes farther ahead as it does not need to constantly start and stop new fx. So it is less noticeable when it gets out of sync.I've been having some sound issues. If going to the pause menu and unpausing, every sound (not including music) plays a second time but more crackly. Eventually the first sound just stops playing. Is there a fix for this? I'm on a 9.9 O3DS using Ironhax with the updated boot.3dsx.
