Audio is broken when playing Dokapon Kingdom on traverse servers

[Junepie]

I have no clue why, but when I'm playing online with other people playing Dokapon Kingdom online with friends the audio is completely broken. No audio whatsoever. The audio works OK for the other players, but nothing I do works. The audio works fine when I'm playing by myself, it's just online play that is broken. I tried all three DSP Emulation Engine options, but beyond that the potential for fiddling increases a lot and I don't want to waste my friends' time starting and restarting the game over and over as I try every possible config option. My friends don't have any issue so they don't know what to recommend.
