Pi4 - 4.7.1x after recent update audio little glitch/struttering or miss some frame on some libretro core... it's fixable ?
-
i believe i'm seeing this same issue now. i am on a pi4 playing a lot of SNES right now (so an entirely different emulator), and at random intervals (can be 10+ minutes) I get a second or so of sound cutting out. no frame-drop, just the sound cuts.
if i switch
audio_driver
toalsa
(it defaults toalsathread
on pi4 in current retroarch, following a recent change), the drops never happen.verbose logs reveal nothing. it's strange as the alsathread driver is well-tested on the earlier pi systems, so i'm not sure what makes the pi4 different, or why there's not more talk of this issue. perhaps there's something else unique about my/our setup.

@dankcushions thank you so much for the side-note concerning "alsathread".
I was not aware of that and had a look yesterday...all my libretro-cores were set to "alsa".
I had sound-issues (hickups, something that sounded like switching from mono to stereo during gameplay and so on...) in all cores since i started with the Pi4 and thought it will be fixed with upcoming updates.
But changing the Audio-Setting in RA from "alsa" -> "alsathread" did the trick!
Sound is stable now and...performance-boost!
Yeah, now i.e. "Virtua Tennis" (Dreamcast) or "Mat Hoffman BMX" (Dreamcast) run flawlessy :D
Thank you very much!, i had no idea that the default audio-settings have to be changed to get a good performance. -
@sirhenrythe5th no problem :) it will be the default in future images at least.
let me know if you get any audio drops! the gameplay should keep going but the audio cuts out for a second or two.
