Audio Settings w/ PulseAudio

bluestang

@mitu I think there may be an issue with the PulseAudio settings in audiosettings.sh?

I have a fully updated, stock RetroPie image on an RPi4 4GB and I installed/enabled PulseAudio.

However, when I go to the Audio menu in EmulationStation I do not get any options to choose the output - HDMI 1 and/or Headphones...

All I get is the 3 options - Mixer, Reset to default, and Disable PulseAudio.

pacmd output below:

pacmd list-sinks | grep -e 'alsa.name =' -e 'index:'
    index: 0
		alsa.name = "bcm2835 HDMI 1"
  * index: 1
		alsa.name = "bcm2835 Headphones"

I'll take a look - does the Audio menu shows that PulseAudio in the title ?

Yes, the title reads Set audio output (PulseAudio).

I can also confirm that removing PulseAudio via apt will once again allow me to choose the output - HDMI 1 or Headphones.

The title in that cofing reads Set audio output (ALSA).

Sadly, can't reproduce the error.
Can you run

sudo __debug=1 $HOME/RetroPie-Setup/retropie_packages.sh audiosettings gui 2> audio.log

and post the resulting audio.log on pastebin.com ?

hmmm this seems like the error:

++ sudo -u pi XDG_RUNTIME_DIR=/run/user/1000 pacmd list-sinks
++ awk -F '[:=]' '/index/ { idx=$2;
                         do {getline} while($0 !~ "alsa.name");
                         print idx,gensub(/"|bcm2835\s+/,"","g", $2) }'
awk: line 4: function gensub never defined

The full log is here. (I had to reduce the log because it exceeded the max size for a free user)

FWIW, I don't have the desktop installed, so not sure if that is contributing to the issue.

@mitu I just ran it down to not having gawk installed via apt. Looks like this needs to be a dependency added since evidently this is not installed on the stock RetroPie image?

@bluestang I see, forgot that Debian defaults to mawk instead. Thanks for reporting it, will have to figure out how to solve it either by installing gawk or use mawk instead (preferred).

No problem, I stumbled onto the issue trying to reproduce an error from another thread.

IIRC, installing PulseAudio for the first time defaults to the Headphones sink output. This is evident even on the Full RPiOS images, where I would manually set the output device to HDMI via the sound control applet on the desktop.

On a separate thumb drive that I have the stock RetroPie image on, I manually set the sink output to HDMI (index 0). Once this issue is resolved users should be able to select either one depending on their setup.

@bluestang It should be fixed now in latest RetroPie-Setup, make sure you update if you wan to test it again.

Thanks, works as expected.
