Update with more information. So if I switch to a different TV the audio problem vanishes and it works fine without unplugging and repluging. However a different issue shows it self on the new tv. Emulation station flashes black randomly it seems to occur more during heavy scrolling and subsides if i am not moving around in emulation station at all. But in game everything works fine. Thoughts or ideas?
Installed BaReinhard's repo and rebooted. I was able to connect to the AirPods when it launched back up and for a brief moment sound actually came through from youtube on the AirPods and I thought I may have fixed it, but then it cut out again after about two seconds. I'm getting the feeling that it connects and then gets disconnected almost immediately for some reason. Indeed, looking at bluetoothctl it seems to connect then disconnect to the devices immediately.
I remember long ago that with Midway games in Mame, you had to go into the service menu of the game and turn the volume up.
This is right as the default volume is quit low on these machines.
But in the end you should hear something (very quit...but no silence at all), and the author mentoined that he allready used the volume control in the service menu ("F2").
Just to mention it: AdvanceMame has this great feature "auto level volume" which prevents me from running to the volume control on my setup as i dont have a remote control for my 2.1 logitech-soundsystem :)
Sorry for posting in an old thread, but I'm having this issue myself. Exactly as described in the OP. Only happens with Bonk's Adventure, both the US and Japanese versions. I'll try OP's fix, but I wonder if this is something that could/should be looked into?
@t3stin I don't know, I use a stock config and this is not set on my system. If you just want to test the sound, there's a command line speaker-test command you can use. Or download an .mp3 and play it from the command line with cvlc.
For the video, I've tried two different solutions, neither of which worked:
Modify the /opt/retropie/configs/all/retroarch.cgf file, specifically uncommented the line video_monitor_index = 1. I've had the value set to 0, 1, and 2. Each time, reboot and start emulationstation. It caused the system to slow to a crawl and forced me to reboot via ssh. Video still only displayed on the touchscreen
Followed directions on this post to create a script for emulationstation: https://retropie.org.uk/forum/topic/7517/retropie-ubuntu-dual-screen/4
Script had the same effect as modifying retroarch.cfg. Emulationstation would load then the system would slow considerably.
For the sound: I've tried modifying the sound settings in emulationstation to each of the options (digital, analog, pcm, etc.) and tried running a game. Sound is still choppy. Also tried a test mp3 file with vlc player in desktop. Test file plays back correctly.
For the controller: I've tried re-configuring/remapping my controller and unplugging my keyboard while emulationstation is running. When I launch a game, the display does show my controller is connected at port 0. So not sure why it won't pick up the direction pads or analog sticks.
@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.
