I did not have the time to do some tests like you people did, but it is good to know what it seems the root cause for this problem.

Amazing that a simple thing as an electric audio signal can have this kind of impact.
As I´m using an old 19 LCD square monitor and a power amplifier for the sound, HDMI is not in my universe right now, so I´m stuck here.

Really hope for some kind of firmware update to solve this issue.
Thank you all for your replies!

Solution confirmed, found a way to extract audio signal from HDMI cable, never again a freeze with controllers ... hope that the problem with 3.5 is solved anyway at some point

I also do have this problem with an up-to-date Retropie 4.7 on my Pi 4. Since I had a similar hdmi converter lying around, it became my provisional solution for now.

Let's hope that future updates of Raspberry Pi OS will fix this issue someday.

Strangely, on my system only the other hdmi port away from the power plug has video and sound. 😛

my audio to HDMI setti

been going crazy trying to fix this issue. got another microsd card and imaged it to see if that fixed it. Nothing would work. Switched from a monitor to TV and changed to HDMI for audio and it fixed the issue.

Just to confirm i got it right:
as soon as you use the 3,5" jack for audio you run into these problems with USB-Controllers?
So the Pi2Scart Device is also useless as it uses the 3,5"-Jack to get the audio-signal?

In my case, yes.

@clyde thanks clyde!
Gosh, the Pi4 is a great piece of hardware, no doubt!
But it is PITA for anyone trying to get the beast connected to a CRT compared to the Pi1 to 3 :/

Just FYI, @mitu gave this tip in another thread:

@clyde This issue seems relevant - https://github.com/raspberrypi/linux/issues/4610. Try using audio_pwm_mode=1 in config.txt and see how it works.

I'll test it as soon as I have the time and leisure to work on my cabinet, but I don't know exactly when that will be.
