ok, so this IS a known issue!

http://mailman.alsa-project.org/pipermail/alsa-devel/2013-January/058136.html

i think i’s just a search now of a work around. thats for all systems, as this happens to me with psx, neo geo, sega cd and pce. not sure if any others are effected, i’ll hopefully get to check this out over the next few days.

but any suggestions, or help would be wonderful,

thank you sevik
