@binarymessiah said in Low volume on videos with OMX+PCM:

Yeah not using OMX leaves me with no sound in the video snaps

That means the vlc built-in video player doesn't have the right audio settings. I remember now a while back a similar topic with the audio output from the Picade, the issue was that the I2S card doesn't have a volume control exposed to ALSA, so the volume slider has little effect.

Does alsamixer show any volume control for your card ? I assume that the configuration for the Picade has disabled the on-board audio, otherwise in-game sound wouldn't have worked.
