Comment 18 for bug 188567

I tried zsnes -ad sdl too, and several other variations in both parameters, config-files and zsnes-versions. Sound works in Zsnes, but it still stutters, almost "vibrates", in a quick sine-wave kind of way. In the current state, zsnes is not usable for me. I've also seen this problem in other applications, specifically a game called Adanaxis ("adanaxisgpl" to run). This leads me to believe that this is not an issue with Zsnes, but with Pulseaudio.

Btw, "paplay any.wav" works fine here, but speaker-test does not work, even with pasuspender:

% pasuspender -- speaker-test

speaker-test 1.0.15
