Sound echo in NBA hang Time by Midway

[Cleverone]

    Seems that theres an echo with the sound in this game in Mame. Iam using  MameUI32 0.136. The sound wasn't working and had to hit F2 to turn up the volume. NBA Hang Time is fun but the echo in sound is bad, it runs a bit slow while playing the game to. While the game is in attract mode doing demo's the game runs fast and smooth, but coin-up and play seems to slow down a bit. This echo occurs in just a few other games as well. Whats the fix on this? Thanks in advance for advice and help.

Do a little search on Midway games and sound issues.  Theres a few threads around with some options to try.  Processing power is the main problem

Thanks, NBA Jam works great so does NBA jam TE no problems, just "Hang-Time is the one.
