Summary	03417: 8ball, 8ball1: Missing Billiard ball noise/sound.
Description	There is no ball sound since MAME 0.56 in Video Eight Ball and clone. The game has 2x DAC sound and TMS5100 for speech and not any sound for the balls. There is no other Century CVS System Billiard game that can be compared with Video Eight Ball, but the Donkey Kong conversion Eight Ball Action (DK conversion) has sound for the ball movement.

No.04890 Tafoid Administrator Sep 2, 2009, 15:47	I tested as early as 0.37b15 on 8ball and 8ball1 - neither of them had a sound for the ball movement. Are you positive you heard ball movement noise? I tried 0.55 and 0.56 and noticed no difference between the two. Comparing to another game (Eight Ball Action) is not valid as there is completely different hardware at work and it's not the same game. Unless you can get some recordings to back up the assertion that there is, in fact, a ball movement noise missing - this will be closed.

This needs verification whether those are ignored on purpose or we have a bug in the emulation. The sound latches stem from the speech soundlatch. The commands e5 and e6 will trigger both a speech and a audio command. This is weird. 2b40 : CVS: Audio command = e5 Warning: sound latch 1 written before being read.
