@sexbeer I had a similar issue. It's related to a Pi OS update rather than RetroPie itself. There appears to be a few solutions depending on your setup, but the quickest, hassle free way of fixing for the time being is to open up your /boot/cmdline.txt and add the following to the end, which enables ALSA compatible mode: snd-bcm2835.enable_compat_alsa=1 If you haven't changed anything else to try to get it to work, a reboot should be all that is required. Thanks

Try something the configuration from https://sinisterspatula.github.io/RetroflagGpiGuides/StereoDownsampleFix.

I just bought some cheap PC speakers off ebay and then dismantled them from the case. They work well in my bartop.

@77claws Have you tried configuring the sound output from the Audio menu in RetroPie ? Choose the Headphones jack as the default sound output and it should route all audio over the 3.5mm jack.

Just a thought.....if <textlist name="gamelist"> with <scrollSound>./art/scroll.wav</scrollSound> was added to the grid view, that would enable scrollSound whilst using the grid possibly? maybe that's a workaround?

If the games are playing fine with mame2003 then I wouldn't worry about the romset itself, just the sounds for the right romset. Maybe check the permissions of the sounds as well, I think as long as they are world readable then its fine. I'm pretty sure I used the same sound files for mame2003, when I moved over to advanced-mame I just copied them to it's samples directory. It's a different romset though. I double checked and the sound files I am using are from Twisty's mame sound collection.

@sirhenrythe5th Considering it will cost me about as much to buy the decoder and if it really won't do anything else, I might as well get some different speakers. Thank you.

Please add more info about your system, as detailed in https://retropie.org.uk/forum/topic/3/read-this-first. What's the content of your config.txt file ? Post it here in the topic, surround by code tags (add ``` before and after the text, on separate lines).

You can use a simple python script to catch GPIO input presses and translate them to volume change commands. Here is an example on how to do that - https://www.raspberrypi.org/forums/viewtopic.php?t=222763.

@RpiBeginner please complete more information as detailed in the link below. Please do not post a support request without first reading and following the advice in https://retropie.org.uk/forum/topic/3/read-this-first

I've enabled Pulse again for within EmulationStation. It seems to fix my problem so far. I'll keep a close eye on this.

@RpiBeginner just wanted to point out that your screenshot is 'aplay -l', and the instructions say 'aplay -L'. You need the capital L option to get the right output. That will allow you the correct name of the audio card. Each audio card has one or more audio mixers (audio devices) on the audio card. Emulationstation needs to know which audio mixer to use on the audio card when you do the volume up and down. To find that out you need to use 'amixer scontrols -D <AudioCard>', where <AudioCard> is replaced by the name of your audio card you got in the previous step. I know from your screenshot that your audio card is set to the 'default', so you should run 'amixer scontrols -D default'. That command should show you the correct name of the audio mixer on your 'default' audio card. It will most likely be called 'Digital' or something like that. Please note that you must copy the name exactly as it is printed. Those two commands above will give you the settings you need. The first command gives you the name of the audio card you select in emulationstation, which is 'default' (based on your screenshot). The second is the name of the audio mixer (audio device) on that audio card, which you'll need to run yourself to get. That would be all you need to get around for most things... Except video sounds. RPI uses OMX player to play the sounds from video files, and they need a third setting! This setting looks different again from the ones we got earlier. The format is: 'hdmi:hw:0,0' That setting will use the first mixer on the first audio card for video sounds. If that setting doesn't work then you should try 'hdmi:hw:0,1', which will use the second mixer on the first audio card. Hopefully that will give you all the information you need right there. Remember that if you cannot select the setting directly from within emulationstation you can add the setting directly to the es_settings.cfg itself . Please see the instructions page I linked to earlier for more details if you need to do that. Hope this all helps! Good luck. Tminit

@mitu Hi! I just wanted to let you know that i have fixed the problem. I bought a Raspberry Pi 3 Model B+ and that seems to fixed the problem. Thanks for testing and helping me out! Greetings Stefan

@RpiBeginner Thank you. English isn't my native language and I wasn't sure if you meant "[A while ago] I tested it with my pc [and there was no hiss], and [now on the Raspberry Pi] the hiss is still there". :) So it may very well be that the usb card is faulty or just not very good.
