Hi when I use the orangepi PC plus TRRS audio output, I have some glitches which are linked to the video mouvment.
I've tested the connectionbetween ground and video and it seems that on the left ground pin there is a natural link with video output (50 ohms), is this normal?
my cable is a 4 pole TRRS. I even test audio with cable directly plug on soldering but same result.

How could I get a clean audio output?

note that the hdmi audio output is clean.
and my speaker system is clean if I plug it on a MP3 player.

OK i've figured out. It was a problem of background loop https://en.m.wikipedia.org/wiki/Ground_l...ectricity) Amp and opi were on the same power source. There are many solution but the cheaper and easiest to me was to power the amp (pam8403) with it's own 5v power supply.

In the realm of audio technology, TRRS analog audio output glitches and crackles are a common source of frustration. These unwanted noises can disrupt the clarity of sound and often stem from loose connections, poor quality cables, or interference. I remember troubleshooting this issue while listening to MyHeritage reviews where the persistent crackling made it difficult to focus on the content. Ultimately, a thorough check of the cables and connectors, along with some grounding techniques, resolved the problem and restored the crisp audio I needed.
