Audio problems on RPI3B

[yaksha42]

I made the changes in EmulationStation to match above. The "Invalid CTL hdmi" error went away but I am still getting the "Failed to attach to default card!" error message and the audio is still not working correctly.

@yaksha42 Did you entered hdmi in the configuration file ? Try to enter it as uppercase - HDMI.

[yaksha42]

I entered it all in caps when I did the initial change.

<string name="AudioDevice" value="HDMI" />

I just tried.

sudo apt update
sudo apt full-upgrade

And now I have no sound at all. I checked all the configs and everything still seems to be set correctly. It's a fairly new install of RetroPie so maybe it's a good idea to just re-image the SD card and start again?

Can you run

aplay -l

and post the output ?

Ok, so this shows you're using the latest Raspbian updates, which changed the audio setup. If you've chosen HDMI in the Audio menu, then a configuration file should have been created in $HOME/.asoundrc, where HDMI should be set as default audio card. The contents of the file should look like this:

pcm.!default {
  type asym
  playback.pcm {
    type plug
    slave.pcm "output"
  }
  capture.pcm {
    type plug
    slave.pcm "input"
  }
}
pcm.output {
  type hw
  card 0
}
ctl.!default {
  type hw
  card 0
}

If you don't have this file, then update RetroPie-Setup to the latest version and re-configure the Audio menu from in the RetroPie system (not in EmulationStation). Try again and see if your games have sound.

I didn't have the file so I updated the RetroPie-Setup. I configued the Audio menu in RetroPie to be "HDMI 1". I am still getting no sound in any games.

Does speaker-test produce any sound ? Make sure the volume is up (use alsamixer to check/modify it). If that doesn't work, then I don't think is a software/configuration issue.

[yaksha42]

I couldn't get speaker-test to work, or aplay. alsamixer had volume.

I ended up just re-imaging the SD card with a fresh copy of RetroPie. This fixed my issue. All ROMs I've played have had appropriate audio.
