Pi4 audio settings for HDMI

wild snail

With 3,5 mm jack the sound works good.

wild snail

Where can i enter the code : sudo amixer cset numid=3 2

Clyde

@wild-snail Press F4 in Emulation Station and you'll land in RetroPie's command shell. Enter exit to return to Emulation Station.

wild snail

Ok i go try if i get audio over HDMI now

wild snail

Way to complicated this.
Do i have to enter this code every time ?
I only have a gamepad not a keyboard.
I need to find a usb keyboard that has a = character.

It looks like DOS with F4, i dont want to be here.

@wild-snail then retropie may not be for you. this kind of configuration is usual.

instead of buying a keyboard you could remotely connect to command line via a PC/laptop/etc using SSH - https://retropie.org.uk/docs/SSH/

wild snail

No, it is for me, only the sound dont works over HDMI.
Else i dont have to configure anything just play.

Clyde

Most of the current sound problems are caused by a recent update of the underlying OS „Raspbian“. Maybe yours are, too. See here for comprehensive information and workarounds.

Thanks for the help, i appreaciate.

I went to my uncles house with this thing, connected it, played with settings, and all the sudden there was sound.
I was very happy, and went back to my house.
Then there was no sound back home.

Maybe my TV is to old ?, 10 years old, while my uncle has a new tv.
Can HDMI be not backward compatible ?

I go try buy another cable see if that works,
if that is true i wont ever buy anything original with a raspberry logo on it.

Sorry for the stressing, it is my TV.
Anyone know anything about this HDMI backward compatibility let me know.

thanks

Because of the cable? Nowadays, most "vendors" of simple parts like cables buy from the same few factories in asia who are making them in the first place, and put their own label on them. Thus, the quality the customer gets comes down to some QA and a big heap of randomness.

Shunning a certain vendor just because of one bad cable seems a little exaggeration to me, and may cut you off from an otherwise excellent hardware source, which in my experience the Raspberry Pi Foundation really is – just search for power-related Pi problems with non-original power supplies.

Just my two cents to maybe save you from a severely wrong decision. 🧐

That said, I'm looking forward to any update about the matter. I wish you success.

wild snail

I tryd another cable and it dit not work either.

wild snail

I just wait for a update image on the site that solves this, i am reading this :
https://retropie.org.uk/forum/topic/26628/audio-issues-after-latest-raspbian-updates/17

Good luck

@wild-snail I don't understand what update you're waiting. If you read the post, it outlines what configurations need to be done - after Raspian's updates - so that audio works in EmulationStation. If you're using the 4.6 image, but you didn't update your system, then you will not be affected by those updates.

wild snail

Ok thanks
maybe i just need a new tv.

Clyde

Does your TV or your sound system have other audio inputs? Then maybe the audio jack of the Pi could be an option? (This should be obvious, but sometimes we miss the forest for the trees.)

wild snail

Yes i have my pc-speakers at the moment, only it is a mess with all the wires.
I really think it is some PCM problem, with samplerate or channels.

GreenGriffon

@mitu You don't understand why people might be waiting on an update to fix a problem that breaks the sound in ES on a brand new installation of the official RetroPie image?

mitu

@GreenGriffon Yes, care to explain me ?

I agree with mitu. There is no need to update the pi for this, since you only need to change your audio settings.

wild snail

Well then tell me please how do i change my audio settings ?

The Pi3B works fine on my TV, the Pi4B not, it does work at other TVs.

So what is changed in the Pi4 audio compared to the Pi3 ?
Is the samplerate increased ?, maybe there is channels added for surround ?
All these things can give problems on my 10 year old TV.

So dont say i need to change my setting if you dont know how.
