Audio issues after latest Raspbian updates (June 2020)
-
@draxd said in Audio issues after latest Raspbian updates:
What I think happened in my case is that on boot Retropie updated firmware and kept old kernel modules that do not work with this firmware.
If you used
apt
to update your system, then I don't think that's the case. The only method I'm aware that can mix/match kernel and firmware versions is usingrpi-update
and skipping kernel updates.I do have backup of my image from time when it worked properly. Is there any way to revert to my old firmware and disabled updates of firmware ?
The subject of this topic is how to change the settings so your audio works after the latest update, why do you want to downgrade instead of applying these new settings ?
-
Hi, I managed to fix it by updating kernel and fallowing your instructions. Thanks.
I do not know how system updated to latest version of firmware. I pretty much did nothing. My Raspberry pi was offline for
pretty long time (for few months, playing retro games don't really requires internet) and this happened first time I rebooted it after connecting to Internet. -
@mitu i am working on my first project ever, and i just started working on audio today. i have the pi zero w, and i plugged headphones into the display, which is connected to hdmi. i have never had it working and the volume slider keeps resetting to 0%. which fix should i try?
-
@tendiesaregood The Pi zero W doesn't have an analog jack, just the miniHDMI port, so your sound should be configured with HDMI.

@mitu This is driving me absolutely batty... I set up the latest version of Retropie (4.6) downloaded directly from the website this morning to install on my 3B+. Upon first boot, I am able to do everything normally, but I have no sound and no matter what option I select from the menu, I get a message saying "failed to find mixer elements". I am using an HDMI monitor with no built-in speakers, so I have a small USB amplifier with a 3.5mm audio jack plugged into the Pi. I have tried everything on this thread and nothing seems to work... adding text to my cmdline.txt file added a few new options to my audio settings (previously it was just HDMI and headphones), but no matter what I select, I still get no sound and the "failed to find mixer elements" message. What am I doing wrong here?

@momentarydogma Did you set your Audio output from the RetroPie menu ?

This brings up an interesting question. If I wanted to use a Pi Zero for a portable music player, what is the best way to get good sound from it other than an HDMI connection? Is there a way to output decent sound to GPIO pins that an audio amp chip can use?

Either via GPIO - there's a plethora of Audio DACs that work like that - or with an external audio card connected via USB.
-
@mitu Yes, I have tried every option... at first I had "HDMI", "Headphone", "Sound Mixer" and "Default" none of which worked. When I added the above text to the cmdline.txt file, it expanded to add "Auto" and changed the "Headphone" option to something like "Headphone - 3.5mm". When I select "Sound Mixer" (or whatever it is), it allows me to hit F6 to select my soundcard. Previously, I only had 2-3 options, but now I have six, none of which make any difference.
-
I would also add this-- the amp I'm using is only connected to the Pi via 3.5mm audio. It plugs into power on its own, and it works perfectly when I connect it to other devices via the 3.5mm jack. I'm not trying to output to a USB soundcard or anything-- I just want the audio output to go through the headphone jack on the Pi. I have also tried connecting the Pi to other powered speakers and I have the same issue. What is preventing the Pi from sending an audio signal through the headphone jack? Or is that even the problem?
-
@momentarydogma Don't modify the
cmdline.txt
, it shouldn't be needed and you should remove the lines you added.
If you selected the Analog/Headphone audio option in the Audio settings, then in EmulationStation the settings should be Card: Default and Device: Headphone. -
Okay, I removed the lines I added to the cmdline.txt file and selected the Headphone audio option in the Audio settings, then selected "Default" and "Headphone" in the EmulationStation settings. This actually got rid of the "failed to find mixer elements" message temporarily, but it unfortunately did not end up providing any sound... I tried restarting ES to see if that would help, but then the "mixer elements" message just automatically came back. On a whim, I tried selecting HDMI from the Audio settings and the ES settings (even though I'm using the 3.5mm output), but that just resulted in THREE iterations of the "mixer elements error". There is another setting in the ES audio settings titled "OMX Player Audio Device"-- do you have any idea what I should set that to?

Check the volume - software and hardware.

Re-read my first post, at the top of the topic.
-
@mitu okay, here are the lines from my es_settings.cfg file:
<string name="AudioCard" value="default" />
<string name="AudioDevice" value="headphone" />
<string name="CollectionSystemsAuto" value="" />
<string name="CollectionSystemsCustom" value="" />
<string name="GamelistViewStyle" value="automatic" />
<string name="OMXAudioDev" value="alsa" />Those seem to match up with your original post-- should I change them to something else? Also, the software volume is currently set to 90%, but sometimes it randomly goes back to 0% upon reboot.
-
@momentarydogma The settings are correct.
-
@mitu Well, if that's correct, where do I go from here? I have verified that those settings are as they are supposed to be, but I still get the mixer settings error. The only other thing I could point out is that the OMX options also include "ALSA:HW:0,0" and "ALSA:HW:0,1". Does that mean anything? Keep in mind, this is a fully fresh install of Retropie 4.6-- I encountered this problem directly out of the box.

If you haven't updated anything on your image, then the instructions here don't apply, though I outlined the correct settings - before updating - in the first post. You can check if you have the updated kernel/firmware as described in the 1st post.

Verify that you have the updated kernel/firmware, otherwise the settings you posted above don't apply.
-
@mitu The very first thing I did was update the kernel and firmware. I did this before I realized that there was an issue with the audio. The first thing I was attempting to do was to install Attract Mode, and the very first step in the guide for that is to update the kernel and firmware. The first time I saw the "mixer elements" error was when I went into the package management console immediately after I had done those updates. I can also verify that I put in a different SD card with a 4.2 build from a prior setup (different 3B+) and the audio works with no issues. Thanks for all of your help!

This is not what 'out-of-the-box' means.
I advise you to reflash the image, update your system and packages and then re-do the settings for Audio as outlined in the first post. You don't to edit any files, just use RetroPie-Setup and the EmulationStation's settings from its menu. -
That's precisely what I did to begin with... I flashed the image, updated the system and packages, then I came upon this post once I realized that the audio wasn't working properly. I initially used the Retropie setup and configured the ES settings exactly how you described at the beginning of this post, to no avail. The only reason I edited any files was because you recommended doing so in order to revert to the previous audio configuration. But I'll try it again and see if that works. Thanks again!
