@152adam Just tried it in bin/cue format and the soundtrack is working now. So it seems likely the .chd format is the source of the issue with the cd audio. Wonder if anyone else has noticed this problem.

What settings do you have in the Sound section in Emulationstation ?

Thanks all for your help. I found a good image for the Pi0 and dont have any problems now :) Image: Super RetroPie

@ahndrooan You can edit the topic title - there's no 'solved' checkbox :).

@quicksilver hey pal. Thanks for the advice! That did the trick. :) Cheers!

@mitu Thank you. I sorted it. I changed the TV itself to "external speaker" only and the Pi to hdmi. It seems to work fine now. I get no audio at all when I choose "3.5" or "auto".

Oh sorry misunderstood. Well, it's a little bit all over the place. Before overclocking, one TV I tried had 720p. It had occasional audio cut outs. Another TV had external speakers and had a resolution of 1920x1080. That one had terrible audio drop outs that lasted the longest. The last one I tried was at 3,840x2,160 and was working better than the other two. The audio dropouts were there but they didn't last as long. Since that 720p TV still had audio drop outs, I don't think that could be the solution. But I haven't tried changing the resolution for any of the TVs so I'm not 100% sure.

I have this problem each time and have to remember to set it both in retropie and using the raspbian tools. Oh, and remember to turn up the volume on my amplifier :)

Thanks guys, my Friend borrowed the pi, so I will post The Result in a few days. Thanks you very much.

@rc_cola Once when I experienced problems with cd tracks on psx games, I experimented with different audio drivers. If you dig more and search the web, you will find some different opinions. I think one of the audio driver will synchronize with video and if you get frame drops or anything else can't keep it up, then audio starts to stutter. Changing the driver did resolve this problem, if i remember right. The audio wasn't no longer synchronized, but it sounded without problems and I couldn't tell anything wrong with it. It was only happening with cd tracks. So, in short, this could be one of the tradeoffs. I have no more details about this, sorry. Btw, you may find more information if you search about these topics in generell, like sdl vs alsa. These are common in Linux. And just in case you missed this page: https://retropie.org.uk/docs/Sound-Issues/ Note, they speak about older Raspberry Pi versions on this page.

don' t work i run your comand but the audio in the rom not working can i help me? i mod the the retroarch.conf for working audio?

Dont worry i fixed it turnes out i just had o switch the audio from auto to the audio output in the audio menu.

@mitu Thanks so much!! It finally works! I get sound when I boot it up!

Just to give this thread and all you guys some closure, I have not experienced any slowdown on PS1 games since installing Retropie 4.4 from scratch. Perhaps it's the new version, perhaps it was some tinkering I had done and that has now been erased. I did notice that PS1 games tend to slow down on my Pi2 when enabling enhanced resolution, either with or without the speed hack. I have not yet tampered with the overclock settings and I'm not sure if I should, since it's a Pi2... Otherwise I'll simply stick with the bilinear filtering option, which slightly improves graphics, and wait for the Pi4.

@dankcushions said in Garbled Audio when crt shaders enabled: the ‘new style’ xmb menu is not enabled in retropie by default. we use the old green menu for these kind of reasons. i guess your configs are all messed up and it’s using default retroarch settings, so all bets are off. Yep. I got it fixed now. Not even sure how exactly but I noticed that my nes and gb system cfg files had a ton of stuff in there copied from the default retroarch. I just rebuilt them by hand and all is well now.
