Slowness of certain emulator when using hdmi audio output

Hello batocera team

I use the last batocera 5.26 64 bit for HP EliteDesk 800 G5 Intel Core i7. Since the last weekend I added an nvdia 1030 gt. I activated the nvdia driver.

I then chose the hdmi output for sound and it works in the menu But in some emulator like the super nintendo I have no sound and especially I have huge slowness. For the negeo I have the sound but very bad and very slow. And if i switch to the output jack audio its perfect for video and audio for super nintendo.

By cons on the big ps2 dreamcast ps1 emulators no sound or lag problem with the output hdmi.

My hdmi cable is plugged into an amplifier.

thank you very much in advance
