I’m running RetroPie 3.0 on a Raspberry 2b and everything is working, except the audio performance via 3.5 audio jack is awful.
N64 Emulator Mupen64plus runs very smooth with the default output via HDMI but when you change “/opt/retropie/configs/n64/mupen64plus.cfg” to output via analogue:-
Audio output to go to (0) Analogue jack, (1) HDMI
OUTPUT_PORT = 0
The emulator lags really badly due to the picade bootloader (BL) light flashing. Is there any way to resolve this issue ?
This is present on all emulators where you have the Raspberry volume (AlsaMixer) above 44 (in the green zone), but more of an issue with demanding emulators such as N64, Playstation etc
I can drop the AlsaMixer down to 5-10 and the performance improves, but the volume is so low you cannot hear it without putting your ear next to a speaker.
If anyone has any suggestions that would be great,
