Unpopular Opinion
Welcome to the Unpopular Opinion community!
How voting works:
Vote the opposite of the norm.
If you agree that the opinion is unpopular give it an arrow up. If it's something that's widely accepted, give it an arrow down.
Guidelines:
Tag your post, if possible (not required)
- If your post is a "General" unpopular opinion, start the subject with [GENERAL].
- If it is a Lemmy-specific unpopular opinion, start it with [LEMMY].
Rules:
1. NO POLITICS
Politics is everywhere. Let's make this about [general] and [lemmy] - specific topics, and keep politics out of it.
2. Be civil.
Disagreements happen, but that doesn’t provide the right to personally attack others. No racism/sexism/bigotry. Please also refrain from gatekeeping others' opinions.
3. No bots, spam or self-promotion.
Only approved bots, which follow the guidelines for bots set by the instance, are allowed.
4. Shitposts and memes are allowed but...
Only until they prove to be a problem. They can and will be removed at moderator discretion.
5. No trolling.
This shouldn't need an explanation. If your post or comment is made just to get a rise with no real value, it will be removed. You do this too often, you will get a vacation to touch grass, away from this community for 1 or more days. Repeat offenses will result in a perma-ban.
6. Defend your opinion
This is a bit of a mix of rules 4 and 5 to help foster higher quality posts. You are expected to defend your unpopular opinion in the post body. We don't expect a whole manifesto (please, no manifestos), but you should at least provide some details as to why you hold the position you do.
Instance-wide rules always apply. https://legal.lemmy.world/tos/

I did some research about it and it sounds like what I need is a dongle that isolates the charger and audio grounds from each other. Though a ferrite bead might help with the charge whine I get on one of my indoor chargers.
I also did some searching again and came across the usb-c alternate modes. There is an alternate mode for "Audio Adapter Accessory Mode" and this needs certain architecture of the adapter you are connecting to be automatically detected.
From the spec: "The analog audio adapter shall identify itself by presenting a resistance to GND of ≤ Ra on both A5 (CC) and B5 (VCONN) of the USB Type-C plug. If pins A5 and B5 are shorted together, the effective resistance to GND shall be less than Ra/2.
A DFP that supports analog audio adapters shall detect the presence of an analog audio adapter by detecting a resistance to GND of less than Ra on both A5 (CC) and B5 (VCONN)."
So the host has to support it, and the adapter needs to be manufactured so that it turns this feature on.
But i find it difficult to find firstly if my phone supports it, and if the jack is designed with it in mind.
And after that we apply the complexity of also charging in this mode, and chespest possible manufacturing of these things, or they just throw their own DAC in the adapter and call it a day so from phones dac -> usb-c alternate audio mode -> adapters dac -> headphones.
And nowhere have i ever seen the manufacturer of these dongles say how its constructed.
But i will stop here and forget about this because it is way outta my league.
I also have absolutely no idea about if anything i say is correct so readers beware feel free to correct me on all thing usbc!
