No sound on LZDOOM on RPI4

RussellB

The first post in the link I mentioned said to 'revert' back to the settings by adding this to cmdline.txt:

snd_bcm2835.enable_hdmi=1 snd_bcm2835.enable_headphones=1 snd_bcm2835.enable_compat_alsa=1

I did that and it didn't do anything for lzdoom. I tested multiple emulators, BGM, ES and they all have sound except for lzdoom.

I'm using built-in audio, HDMI.

Pi Model or other hardware: 4, 4GB
Power Supply used: 5.1V, 3000mA
RetroPie Version Used: 4.5.18
Built From: Buster Base
USB Devices connected: USB keyboard and mouse, 2TB WD Essentials 3.0 drive
Controller used: 2 Logitech F710 controllers
Error messages received: AL lib: (EE) ALCplaybackAlsa_mixerProc: Wait timeout... buffer size too low?
Verbose log (if relevant): No
Guide used: No
File: N/A
Emulator: lzdoom

I ran into this issue when I did a firmware and OS update and I ended up reverting back to an older OS. I think lzdoom is making some bad assumption about the default ALSA sound device.

Remove any added lines, and do an update of packages

sudo apt update: sudo apt dist-upgrade

I will test lzdoom shortly if it's at fault.

BuZz

You installed manually btw? How are you starting emulationstation?

BuZz

Sound works fine here with lzdoom btw. Kernel 5.4.51 / rpi4 with no changes to audio settings.

I will need more info and examples of logs to advise. An install log for lzdoom also as it gives some info on kernel etc. Can use a pastebin site for logs.

BuZz

Sorry. Just noticed your retropie is also ~~massively~~ out of date, I recommend updating.

[Correction - not massively, but your kernel may be out of date also]

RussellB

I updated the kernel to 5.4.59-v8+, as well as the OS and the issue is still happening.

Here is my runcommand.log: https://pastebin.com/9uMpK3WG
and aplay -l: https://pastebin.com/HYrNYXQ0

It looks like lzdoom can't open the default device anymore. I'll try building lzdoom from source and see if that makes a difference.

mitu

Try renaming the lzdoom.ini file (should be visible in \\retropie\configs\ports\doom) and re-starting the game again.

RussellB

Same thing. No sound.

Without lzdoom.ini here is the runcommand.log: https://pastebin.com/W7XUaRTi

:(

I'm now also getting this message:

"lvl0: VolumeControl::init() - Failed to find mixer elements!"

RussellB

So following this thread:

https://retropie.org.uk/forum/topic/23954/audio-not-working-rpi3b

I was able to fix this message I was encountering:

ALSA lib control.c:1373:(snd_ctl_open_noupdate) Invalid CTL hdmi
1v10: VolumeControl::init() - Failed to attach to default card!

lzdoom is the only software that is having a problem with sound. Splash screen, BGM, ES videos and other games I've tested all work.

For posterity...

I found this wiki page: https://zdoom.org/wiki/Compile_ZDoom_on_Raspberry_Pi

I added .alsoftrc to /home/pi and put this in:

[alsa]
mmap = false

And voila... all sounds and music came back.

I hope this helps someone. It was driving me crazy.

@mitu this is related to pulseaudio. I discovered that I can use "apulse", just type in terminal: apulse lzdoom to have sound with pulseaudio uninstalled, but ... How do I create a shortcut for emulationstation telling it to use "apulse" together with the game?

@renetrox said in No sound on LZDOOM on RPI4:

How do I create a shortcut for emulationstation telling it to use "apulse" together with the game?

I'm not sure your issue is related to the error reported in this topic. apulse is a 'fake PulseAudio' implementation for programs that need PulseAudio - the fact that a program needs it means it was compiled with PulseAudio and expects it to use it - but lzdoom is not using PulseAudio on the Pi. Are you using a Pi or some other platform ?

Renetrox

@mitu Lzdoom does not produce any sound without pulseaudio. I have tried all kinds of proposed solutions for that problem, that's why I got to "apulse" because I discovered that it emitted sound by analog when I installed pulseaudio. This on a raspberry pi 3b

mitu

@renetrox Looks like a different problem then the one in this topic, so I advise to open a separate topic, add the info requested in https://retropie.org.uk/forum/topic/3/read-this-first and post the lzdoom.ini configuration file (use pastebin.com for posting the file, since it's quite large).

Renetrox

@mitu I appreciate your answer, but I don't think it goes out of context. lZdoom has no sound. I applied the solution proposed here without success, that's why I shared my experience. If you can't tell me how to create an access in emulationstation telling the system to use "apulse" then there isn't much to add. At the moment I don't directly use that emulator, I wanted it for action doom 2 and brutal doom, I can live without that;)
i will share the lzdoom.ini file in case it helps anyone

@mitu solution: create a script with the following:
#! / bin / bash
"apulse / opt / retropie / ports / lzdoom / lzdoom" ""

It doesn't work like the other games on the list, but it opens the traditional lzdoom text dialog, the wads should be hosted in ./.config/lzdoom
