I have a suggestion for a clearer definition: Get Super Collapse 2 to
work in Wine without audio artifacts or a mile of dsound err code dumped
to the console.
segin at segin ~/.wine/c/Program Files/GameHouse/Collapse II $ wine relapse
This sound card's driver does not support direct access
The (slower) DirectSound HEL mode will be used instead.
err:dsound:DSOUND_MixOne underrun on sound buffer 0x7fd8f6e8
[*cut for breverity, it's all repetitive*]
