Despatche's bug has been fixed shortly after he posted. (We discussed this on IRC and I gave him a private build for testing.)
Fixed. I introduced that bug when porting the YMF278 core from openMSX.GTheGuardian wrote:Asura Buster (YMF278B) seems to have some clicks occuring from YMF278B Channel 6.

Ikari III - Opening
In case you mean that the first DPCM sound doesn't have a "click" at the beginning - that's an issue of the sound engine.
When starting the game, the DPCM state begins with sample value 0. Playing a DPCM sound raises and lowers the sample value and due to how the engine works, after every sound it goes up to the maximum value (0x3F). (This looks ugly in a wave editor, btw.)
When playing any DPCM sound, the sample value gets reset from 0x3F to 0, so you hear a click.
I will release an updated VGMPlay/in_vgm in a few weeks.
