I've used them in a totem and genie, no issues and rock solid.

you will still want to re-pin all game connectors for reliability.

you do not need the sound card (onboard or not). in my opinion just keep the chimes in the game. clay has guides that show you how to wire in a sound board for missing chimes and visa versa, but no specific sounds have been programmed for joker poker. The board will allow you to use sounds from any game but may have weird results. I used totem sounds in genie for a while before i learned what i was doing.

if it was a molex connectored game i would also replace all of the connector pins (i do this on all bally sterns). you dont need to replace the connectors themselves just all the tinned pins that frequently are corroded, lose flexibility and connectivity. the cost is minimal and with the right tools can be done in 30 mins.

theres a handy edge pin extractor tool that takes out those pins very easy. buy this instead of using a screwdriver if you want to save 30 mins on a game and tons of frustration.
