No HDMI sound

[spanner]

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...?

weird, my capture card works fine with every Mini Console I have, I have 10 of them but they are all at 720p.

I wounder if its OBS making it do it.

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... .
