Hello guys,
I’ve been at this problem for a few nights now, so any help would be worthy of a bronze statue in your likeness.
I’m running RetrOSMC, which is a RetroPie installation built into OSMC ([HowTo] RetroPie and OSMC: Retrosmc - Retrogaming on OSMC).
I’m using a Raspi 2, everything is up to date. Sound works fine in OSMC, but I get no sound in RetroOSMC. I’ve re-flashed / re-installed a couple of times, same results.
I’ve tried setting options in /boot/config.txt such as hdmi_drive=2, but I’m confident that this isn’t the problem. When I run any emulators, it runs without sound and I get stuff like this in the log:
PPU.RenderSub = 0
PPU.FullClipping = 1
Settings.Transparency = 1
Settings.SpeedhackGameID = 7
PPU.SFXSpeedupHack = 0
coldata_update_screen = 0

ALSA lib pcm.c:2217:(snd_pcm_open_noupdate) Unknown PCM default
I’ve tried using sdl instead of alsa, same result.
When I run cat /proc/asound/cards , I get:
cat /proc/asound/cardsIt looks like alsa isn’t recognizing my sound hardware?
I generated a log of my alsa settings:
