I recently installed 9.1-Pulstar on a Raspberry Pi 4, all is working well expect for missing audio when recording in RetroArch.
I have tried many combinations of audio drivers, audio filter, custom configuration, and a vanilla rebuild without managing to solve this issue.
Audio in game works fine, video recording is also working except for the missing/silent audio (the audio stream appears to be present just no sound).
Previously I had been using RetroPie on the same hardware and had no issue recording with sound in RetroArch (although I think I had disabled pulse and was using alsa for audio due to a separate issues),
Is it possible to record with audio using the current 9.1-Pulstar on Raspberry Pi 4 - or is there a known issue with this?
I would love some help from anyone who has successfully recorded audio on a Rpi4 this as this is a showstopper for my Recalbox cabinet build.
