--- Comment #5 from kakurasan@gmail.com --- Created attachment 60122 --> https://bugs.winehq.org/attachment.cgi?id=60122 A hack for setting volume
The problem is that SetChannelVolumes() is unimplemented.
I confirmed this game tries to set the volume to zero in XA2SRC_SetChannelVolumes() when winning in the battle.
StopSoundMem() really stops the sound because Stop() is implemented properly. This works without the hack.
The hack works for me, but I think this is not "proper" fix because this is a hack for limited cases. However, I don't know how to set volume per channel with OpenAL API.
