I checked the audio settings in raspi-config, everything looks normal, HDMI 1 is set as the default, but I don't have a pulse folder in "/home/pi/.config/" at all !?
Sound effects in the ES menus are present, but no sound in the emulator.
Also, I tried my retropie image with b-em pico version and worknig sound, but again there is no sound with this allegro4 version.
Very strange, at first glance everything looks fine, I literally just added Folly's script to scriptmodules/emulators and successfully installed, didn't change anything else. -
Nice to hear my information helped you to get the sound.
audiosettings mixer - pressed 'M' so that '00
Btw. If you use this command it will do the same :
alsamixer@retrofan
Which retropie image are you using ?Perhaps we can find a solution in this thread :
https://retropie.org.uk/forum/topic/26628/audio-issues-after-latest-raspbian-updates-june-2020 -
@retrofan
it's certainly a weird issue - folly's script is absolutely fine
what I don't understand are the differences seen with the pulse audio and missing files
my 'newest' image was downloaded and updated only a week ago - b-em-allegro4 just worked
have you tried updating via command line with sudo apt-get update && sudo apt-get dist-upgrade ? -
My retropie image is 8 weeks old, latest version for sure.
I will try to update retropie and use tips from link that Folly posted... -
The command :
aplay -LIt seems to give quite some useful information.
With that you can see what it uses by default. -
That command gives me the same output as in the picture you posted before.
Raspbian Update / Upgrade didn't help at all, now it's even worse the emulator doesn't work at all, even after reinstallation.
It's time to leave everything for another day. ;) -

It should give you something different.
-l, --list-devices list all soundcards and digital audio devices
-L, --list-pcms list device namesI was curious what your default is, mine says :
pi@raspberrypi:~ $ aplay -L default Playback/recording through the PulseAudio sound server . .Raspbian Update / Upgrade didn't help at all, now it's even worse the emulator doesn't work at all, even after reinstallation.
It's time to leave everything for another day. ;)We will have a try, later again.
Hopefully we get it working. -

Both rpi-imager and the downloads section of RetroPie give :- 4.7.1 from november 2020
I can't find any image of 8 weeks old.
I think that is why you are experiencing audio issues as in that time debian converted from alsa to pulseaudio.
What's the version number of your RetroPie_Setup ?
We are already on 4.7.15

@folly
I decided to wipe my sd card and start again, card imaged and updated via retropie-setup
installed b-em-allegro4 from script - no audio
Pulse folder not present in '/home/pi/.config/'
Installed desktop & rebooted
Pulse folder now present but 'XXXXXXXXXXXX-default-sink' had no entries - added 'alsa_output.platform-bcm2835_audio.digital-stereo' - rebooted
went to RetroPie-Setup Configuration / tools / audiosettings / mixer - changed from Master to HDMI
still no audio
loaded desktop and ran alsamixer from command - changed from Master to HDMI
rebooted and now the audio works???
At a guess b-em relies on the same audio settings as the desktop (runs with xinit) and it is a case of getting these settings in sync with the rest of retropie?I did try to install elkulator via script however from a default installation runcommand gives this output

About the sound, that is something good you found !!!
For the elkulator part.
I think this comes from the fact that there isn't yet an elk.cfg created in the first run.
That is why sed is giving an error.Try a second time, is the error still there ?
-
@folly
just tried again - still getting
'sed: can't read /opt/retropie/configs/electron/elk.cfg: No such file or directory
Shutting down Allegro due to signal #11
xinit: connection to X server lost'(if I manually copy and rename elk.cfg.bak to the config folder everything works)
-
Yes indeed, it seems to be an issue.
I am now on a OS on a pi4 and where I did't install elkulator.
I had the same issue as you.I pasted the elk.cfg into /opt/retropie/configs/electron.
Then it worked.I will have a look when I can.
-
After the install of elkulator I could see in the log that the elk.cfg wasn't copied.
With an other script I had the same issue which I fixed with removing the quotes around the paths.
I did the same here as we don't have to use it as we have no files and directories with "spaces".My test worked.
Can you test it too for me ?My commit :
https://github.com/FollyMaddy/RetroPie-Share/commit/23321be168ba9cab4cf87ab4a6e3f691fb8b31a7 -
@folly
no problem
uninstalled previous version & made sure there were no remnants (just the cfg that was manually copied - deleted)
reinstalled with new script & tested - games load :)
elk.cfg present in /opt/retropie/configs/electronTop Job! :D
-
Thanks for testing !
Really odd that only "double quotes" give these problems.
No idea why. -
You should try this part from @Lister-of-Smeg :
https://retropie.org.uk/forum/topic/29402/bbc-micro-acorn-electron-emu/152 -
I know the emulator is working properly on the raspbian desktop environment, I checked that yesterday.
I use latest Retropie version you mention, which I installed eight weeks ago for the b-em Pico version.
Tested this b-em allegro4 version on it (no updates / upgrade at all), the emulator worked, but no sound.
I allready have HDMI set in alsamixer, but it doesnt help in retropie.
@Lister-of-Smeg tested with fresh image and and confirmed in his message everything that happened to me yesterday.
Today I don't have much time for testing and honestly I don't know what to do next.
The Pico version under the same retropie image has sound. -
Fair enough.
Perhaps @Lister-of-Smeg can walk you through the solution.
Well we keep this problem in mind, perhaps we can find a nice automated solution.You could also make an image with desktop and install retropie on top of that so you can use both worlds.
If you want this and you have time we can do this in an other thread. -
@retrofan
no worries
when I was testing this morning I had assumed that you may not have the pixel desktop installed (retropie setup / configuration / tools / raspbian tools / Install pixel desktop) as the pulse audio folder only appeared after I had done this
Anyhoo
I suspect the issue is only temporary until retropie is updated, as it seems to be a bit of a mix of alsa/pulse at the moment
Perhaps it's not worth jumping through hoops today for something that may be fixed tomorrow? - I just do it for fun
but if you want to try again sometime i'm happy to help :D -
No pressure, really.
Actually, this issue could be easily solved, since @Lister-of-Smeg has a retropie image with fully working b-em allegro4 version and could share it with rest of us for testing, without roms and without violating any rules.
However, this is not possible, because forum forbids private messages, which I have never experienced in more than 20 years on Internet.
Fortunately, this is not a big problem, at the end of the day I will install this emulator on the desktop raspbian, put it in the startup sequence and that is it.
