Title: No HDMI sound
Post by: Amigadude on July 03, 2024, 09:45:15 AM
Some how missed this up to now but I have no sound through HDMI... it's set to HDMI in the prefs...

It does work through the rear audio jack but that is not ideal as I usual have the speakers plugged into the TV so I can hear the machine that is being displayed.

Hello

As you may have seen at the show, that we had HDMI sound working without problems through our display.   Many monitors and TV's have no problem but we have experienced a few that will not play the HDMI sound.  It is a software issue and we are still investigating the cause.  Sorry for the problem.  You can use Bluetooth sound options as another alternative if this helps.

Only tried it on my most modern small TV so far... Samsung T22E310EX

I get some sound on my 2nd display which is a LG 19LH2000 but it's choppy as hell...

I am having the same probelm with the sound, if I use the headphone jack will work properly then, the shuddering or choppy sound it on my PC when its connected to my capture card, I tried it on my TV and I got no sound at all via HDMI, my TV is about 14 years old and only has 2 HDMI ports, its a Hitachi 42 inch that was made by Argos, you can get the same model(I have in my bedroom) that has BUSH as its model name but is the same TV and the BUSH name is owned by Argos, they do not exist any more, only in name...?

That will be down to capture card. Mine does same on video capture.
With TV I use to test all GS's before shipping, sound and amiberry run fine. I will not let it leave here unless its perfect.

Out of interest, which capture card do you have?

My TV has digital TV and Analog TV so was made before the switch over, it was bran new when I bought it from Argos, so its not a smart TV but it is a HD Widescreen TV 42 inch, it was £300 then, it could of been 2008/9 when I bought it, not sure.

My USB Capture Card is a Chinses £15 one, it works with 10 minis OK (PS Classic, Mega Drive Mini 1 and 2, SNES Mini, THEA500 Mini, THEC64 Mini, THE400 Mini, Atari2600 Plus and Atari Gamestation Pro) there is only one other machine that had this kind of problem, the CHA - Capcom Home Arcade, its board inside it was called the OPI because it had the same specs as the Orange PI PC H3 so could be a OPI thing but uses the same board as THEC64 but has a different nand, it has a mmc instead and 512 ram but does have wifi on board so could be the wifi, I am using it on the A600 GS ATM, maybe its causing the audio shuddering.

Its this one... https://www.youtube.com/watch?v=x40-z7rFmWQ

It has a HDMI loop on it so a HDMI output port too so you can connect it to the PC and see it on another TV at the same time.

I noticed if you look through the grill thats in a shape of a Amiga tick, you see a Red LED and Green LED when powered on, the Green LED keeps flickering like a pules, I am wondering if it meant to do that and could be making the audio choppy, its like the A600 GS is like busy doing something else at the same time so makes the audio choppy, like it happened on a PC if you run a emulator then get it to do some thing else and runs the emulator slow or starts to skips frames or when you play music it jumps.

The other thing it could be is my capture card can't handle its HDMI audio, I did plug my speaker from my PC into the headphone jack on the back of the A600 GS but no sound came out of them, they work fine on my PC, they are Creative SoundBlaster Live speakers... :).

No the pulsing or "heart beat" is not related to activity. It's just a default pattern the host puts the GPIO LED into to indicate the board is "alive".

I've not come across choppy audio, it either works or doesn't on the monitors I have, (in facts works with all monitors, doesn't work with video capture box (cheap EZCAP)) the only thing I can think of to make it choppy at present is if the display was in higher than 1080p , which it should be capped to but....

I have recently aquired n A600GS connecting it to my Sony Bravia TV via HDMI and get no audio, I have tried different HDMI cables and ports with the same results.  If I use the 3.5mm port then sounds are working.

Any news on an update/s when HDMI audio maybe resolved?

Its still being looked into. It appears some TV's dont like certain modes. Its not just affecting GS. Its a big problem on Raspberry pi and distros using latest linux.

No worries, thank you for the update.  I'll stick with my 3.5 for now  :)

I just received my A600 GS today and I have the same issue. Sony Bravia TV which works with _everything_ else I own, including various versions of Raspberry Pi  :(

As I posted earlier, its a known issue on certain TV's.
Raspberry pi's have same issue on newer distros. Everything your using must be running on older distros, like Bullseye.

So after the initial disappointment of HDMI audio not working, I finally got around to finding a 3.5mm jack lead and plugged that in. Guess what... no audio through that either! All I get is a click every time something seems like it's trying to make a sound  :(

You switched to Jack audio in menu?

Yes. If I leave it at HDMI, there's no click. Switch to Jack audio, volume up, I just hear that click (like a little pop like when you touch an audio cable), for example when I click on a disk in the games menu.

You know what! Somehow, this was related to screenmode. I changed to 1920x1080@50Hz and everything is now fine!

1920x1080@60 was listed as "Monitor Native Mode" but with that selected, I got no sound and amiberry was running very slowly (30fps and the audio buffer light was flashing).

Very strange as 60Hz is definitely the "correct" mode for my TV (Sony Bravia 4k thing, couple of years old).

Just got my A600GS from the post office tested it briefly.

There is no HDMI audio here either. Its connected to a LG TV, I use the same input as I used previously with my Pi4 that did work with HDMI audio.
Change the resolution to 1920x1080 50hz but this did not help for me. I also tried setting it to 1280x720 50hz, but then all I got was a black screen.

The sound jack is a bit touchy.  I had to play with the plug to get sound.

It's been some months now. Any update on this in the upstream project? btw, I tried searching for issues with Orangepi HDMI audio but not much came up so I think we're relying on your secret sources :D

As I have pointed out, its an issue with the OS. Theres loads of people with no sound on certain TV's / Monitors.
As its an OS thing, it effects any hardware of this type. Its on the Orange Pi forums and Raspberry pi forums alike.

There is no issue with older bullseye, but bookworm as its classed as still fairly new.
We are having to look at ways to try and resolve this ourselves. I'm sure dev will post here if I have missed anything.
