I cant get any sound with .ISO files on gbquad with openmips or openaaf. have tried rca,hdmi and optical with downmix on and off. can you post here your settings if you got it working or report here if you got this probem so we can file a bug. vu+duo with blackhole plays them fine. if you have any suggestions what i can try to solve this issue i would be pleased, this would be essential for my system and I'm kind of stocked here.
