Audio issues after latest Raspbian updates (June 2020)

lazza79

Hi,

I still have problems with HDMI audio on my RPI 4 (4GB Ram). I can't hear menu clicks and in-game audio. I downloaded a pre-made iso that has an audio intro (that I can hear fine) then Emulationstation and Retropie are loaded and I can't hear anything.
I have Emulationstation 2.9.3RP and I updated Retropie and everything else to the latest version as the 21st of October 2020.
I set the "sound settings" as Default - HDMI - ALSA but the volume is stuck at 0%.

Could someone help me?

Best regards,
Lazza79

We don't support 3rd party images, use the image from retropie.org.uk/download.

@mitu thank you for your quick reply, pardon my ignorance (I am still a linux noob) but once I update retropie and everything else in the system to the latest version present in the server, how a third party ISO differ from the official one?
Thanks!

It's configured differently ? Has ROMs ? Has additional installed applications ? We can't be sure how it was configured.

@mitu I see, I will try to contact the creator. Thank you!

I updated to 4.7.1 , After update no sound, is it not solved yet? Or won’t this be solved and will always have to be setup manually?

Here is the steps I took to fix the issue (tested on Pi 1 and Pi 3) Hope this helps. Please provide feedback.

Documentation to Fix Audio Issues with Raspberry Pi and RetroPi (AUDIO JACK)

Revision 1.0

A recent change in Raspbian Buster's kernel/firmware is causing Audio/Sound issues for RPI users - users that installed the 4.6 image or installed RetroPie manually on-top of Raspbian Buster.
Symptoms include:
• Error messages showing when a game is launched (lvl0: VolumeControl::init() - Failed to find mixer elements).
• Sound missing in EmulationStation and/or games.
• System Volume slider stuck at 0% in EmulationStation's Sound settings.
The following document outlines the steps used to correct audio issues on a fresh build of Retro Pi.

Step 1

Configure EmulationStation to the following setting:
Hardware – Default
Audio – Headphones
Mixer to – Alsa
Exit and restart Emulation station
At the menu F4 to exit the GUI

Step 2

See which devices are available to use as a speaker. This is a sample listing.

Use the following command:

aplay –l <- lower case L

**** List of PLAYBACK Hardware Devices ****
card 0: ALSA [bcm2835 ALSA], device 0: bcm2835 ALSA [bcm2835 ALSA]

card 0: ALSA [bcm2835 ALSA], device 1: bcm2835 IEC958/HDMI [bcm2835 IEC958/HDMI]

card 1: Microphone [USB Microphone], device 0: USB Audio [USB Audio]

Based on the above output we have three devices:
• The onboard 3.5mm plug listed as BCM2835 ALSA: Card 0, Device 0 (“hw:0,0”)

• The onboard HDMI connection listed as bcm2835 IEC958/HDMI: Card 0, Device 1 (“hw:0,1”)

• The USB microphone listed as USB Audio: : Card 1, Device 0 (“hw:1,0”)

In this example we want to use the 3.5mm audio jack, so we’ll use Card 0, Device 0 as the way to locate our speaker device.

Validate your device setting. This is key for all the next steps – the following documentation is based on my configuration which is card 1 and device 0.

Step 3

Use the following command:

sudo nano /boot/cmdline.txt

Enter the following entrie:
snd_bcm2835.enable_compat_alsa=1

Step 4

Edit EmulationStation settings

Use the following command:

Sudo nano /opt/retropie/configs/all/emulationstation/es_settings.cfg
<string name="AudioCard" value="default" />
<string name="AudioDevice" value="Headphone" /> --- NOTE Headphone <- The H is capital
<string name="CollectionSystemsAuto" value="" />
<string name="CollectionSystemsCustom" value="" />
<string name="GamelistViewStyle" value="automatic" />
<string name="OMXAudioDev" value="alsa" />

Step 5

Need to run Raspi-Config and set audio to Headphones
From the command prompt type:

Sudo raspi-config

From the menu select:

System Options
Audio
Headphones
Finish to exit to command prompt

Step 6

Use the following command:

sudo nano /boot/config.txt
The following two entries are useful if you want to use the 3.5mm audio output jack instead of via the HDMI cable.
hdmi_ignore_edid_audio=1
audio_pwm_mode=2
Line 1: Force the audio to use the stereo audio jack output.
Line 2: Improves the sound quality and reduces annoying hissing.
Confirm that the following entry exists and it’s set to this configuration
dtparam=audio=on

Step 7 a:
Add the audio output from the command line.
To do this, you will need to create a new file called .asoundrc in your home directory /home/pi/.asound (No extension)
ALSA looks for this file to determine which audio device it should use by default.
If the file does not exist, ALSA uses “card 0” – which is HDMI – as the output device.
If you want to set the headphone jack as the default output, create the .asoundrc file with the following contents:
Use the following command:
sudo nano /home/pi/.asound
Add these parameters
defaults.pcm.card 1
defaults.ctl.card 1
This tells ALSA that “card 1” – the headphone jack – is the default device. To switch back to the HDMI output, either change the ‘1’s in the file to ‘0’s, or just delete the file.

Step 7 b:
Use the following command:
sudo nano /usr/share/alsa/alsa.conf
Edit the file to match your card it may be defaulted to 0
defaults.pcm.card 1
defaults.ctl.card 1

Step 8
Reboot

Step 9
Validate and Configure EmulationStation from the GUI interface (Audio) – confirm that audio is not set to zero
Within emulationstation – confirm that Headphones is selected.

Step 10
PLAY YOUR GAME

Please provide feedback.

There's no need to edit any files - the steps outlined in the topic starter will take care of any configuration file. Your instructions seem to switch back to the previous audio driver configuration, in which case there the issue would not present, so there there's no need for any re-configuration.
I don't recommend changing the /boot/cmdline.txt file to switch to the previous audio driver configuration - the new audio settings enable audio on both the audio jack and HDMI port(s) independently, which was not possible before these changes.

@mitu

Thank you for your feedback.

For those who are experiencing similar issues after the Dec 2020 Raspberry Pi OS update (where ALSA support is dropped in favor of PulseAudio), the following setup works for me in Sound Settings:

AUDIO CARD: HW
AUDIO DEVICE HDMI
OMX PLAYER AUDIO DEVICE: HDMI

Having the same error, however sound works both in emulators and in the interface.
It's just that very same error text appearing everywhere every time, in-between game loads and upon exit.
This is on a pi400 with Retropie sound settings set to hdmi1, but it happens with Auto and default too.

I followed the guide on post #1 (thank you for posting it Mitu), but the line text error remains. Is this normal?

I've also tried setting sound settings as
AUDIO CARD: HW
AUDIO DEVICE HDMI
OMX PLAYER AUDIO DEVICE: HDMI
but the error remains.

mitu

@luckyluca what version of RetroPie are you using ? Did you install the desktop on your system ? Please post some details about your setup, as detailed in https://retropie.org.uk/forum/topic/3/read-this-first, and the output of the aplay -L command.

@mitu

Sorry, you're right. I'm using Retropie 4.7.1, with all installed main core packages updated to the latest versions as per last week. I'm not using a desktop OS, just Retropie. I'm testing this on both the vanilla retropieOS as well as a ready made third party image, with the same results.

Pi Model or other hardware: Pi 400
Power Supply used: Official white PSU
RetroPie Version Used: 4.7.1
Built From: Pre made SD Image on RetroPie website, booting from a samsung sdcard.
USB Devices connected: 1x logitech k400 keyboard/mouse dongle plugged to usb2.0
Controller used: 8bitdo sn30pro,sn30pro,sn30pro+
Error messages received:
volumecontrol::init() - failed to find mixer elements!

Please note audio appears to work just fine everywhere, it's just the error message shows up multiple times, when launching emulators, closing emulationStation etc.

The result of aplay -L:

Although similar, your issue is not same. You updated your system and you installed Pulse Audio (included in the Raspberry Pi OS Dec. updates), which took over as the default ALSA sound device:

default
    Playback/recording through the PulseAudio sound server
....

This doesn't happen on a stock RetroPie image, which uses Raspberry Pi OS Lite, unless you install the desktop.

To get rid of the message, you can simply choose Master as the default Audio device in EmulationStation or disable Pulse Audio by running

systemctl --user mask pulseaudio.socket

@mitu could this issue be impacting splash videos? I currently lost splash videos and images trying to adjust the oxm player sound setting?

mitu

@cnoto The issue in the current topic appeared after the May 2020 updates in Raspberry Pi OS and it affects EmulationStation. I don't have reason to believe this could affect the splash videos audio, which are using omxplayer and don't rely on ALSA for audio.

cnoto

@mitu Thanks for the quick response. I added the video to the retropie default splash video folder and it now works.

Unfortunately, I am here to report after updating every package to the latest, the in-game sound seems to have been lost in my case. This affects all emulators (not just Retroarch, because even Drastic isn't outputting any sound). Still, the sound in Emulationstation works just fine using the setting above.

mitu

@huey Open a separate topic. If EmulationStation's sound works, then this is not the issue reported in this topic.
