Im soo sorry to reup this old topic...but it is umbelivable, after a fresh new install i jump again in the same nightmare
LAG AUDIO always during the game specially ADVMAME.
Actually im restalling from a source all ADVMAME but i think the issue come from the master audio driver, there was some way to reset it?
Another probabily issue would be the playing with a script who change the output of the audio (depends of the rotation i switch from jack or HDMI, yes i have tried to disable them but without helps)
i've found this:
Turns out my lack of audio was because I'd run sudo amixer cset numid=3 1 previously to try to get sound working on FUSE (which turned out to be broken because of PulseAudio!) and forgot to change it back.
A possible solution but i didnt understand what this guy are saying....
Any helps to restore the initial condition of retropie or reset all the stuff would be appreciated!
