SWC Volume Control issues at high volume - MTCB Android Head Units Q&A

I have an issue with my steering wheel controls. They function fine at volumes less than 23 (out of 30), but once it gets louder (23 to 30), none of the SWC (next, prev, vol +, vol - , etc) work. I have it wired in via the "Key 1" wire. The volume knob and system control still function at high volume.
My assumption is that the internal audio amp is drawing too much power, and maybe reducing the +5v supplying the ADC that reads the SWC. Has anyone else experienced this, or know of a solution? I'm debating on wiring an independent +5v into the circuit to compensate (see attached picture).
Any thoughts?

My suspicions were correct. I switched my speakers to the RCA Pre-Outs + Alpine 4channel amp. Now my problem is gone. Seems that the internal amp was bogging things down at high volumes.

[Q] Question, trick headphone connection. From OMTP to CTIA

I have ARC S and I satisfied with it in every way almost. Almost because the passage of headphones.
Because of the combination of his old headphones (OMTP) any quality with a microphone headset not working on it. For example BEATS SKULL etc. ..
Because they all work the latest technologies that CTIA.
So I wanted to know. If I replace the headphone jack of the phone itself. Sony's connection to connect another method CTIA Does it work? Or should be more any material change?
Trick can be so simple and it will work?
??
Here.
The CTIA Technology differs of the other one just what the mic and ground is inverted, like this image can display.
Actually SE make an adapter to do this convertion.
More info in google, XDA doesn't let me post outside links =/
You can give it a try and try to do it by yourself, with a female jack with quadpolar and a male jack same quadpolar.
Greetings and succes!
Here's an adapter

Can 2 channels be turned into 5 or 6 in order to go to a car amp??

Hello,
I am installing my Nexus 7 into my 2009 Dodge RAM 1500 QuadCab. I have component speakers in all the doors (four channels total,) and my tweeters and subs are sharing a channel (split with crossovers) - which all runs to my five channel amp. My question is how to get the best sound from my Nexus 7 to my car amp.
I will be using a USB DAC, but that still only outputs two channels and I need those two channels to somehow turn into five, so that they can go to my five channel amp and from there to my speakers and subs. Is there some sort of audiophile custom sound board out there made for these applications? I REALLY don't want to have to use Y splitters. This would be a piece of cake if I didn't want to have that 5th channel. I would even be ok with having 6 channels.
My Amp: XD700/5
Thanks in advance for any help.
This is what I need help with:

Nexus 5x volume components

Hi,
While I dissasmbled my nexus 5x, I accidently ripped the two components of the volume- button. (You could see it in the upper side of the photo below - the first two components right to the barcode)
I belive it some kind of resistores or capacitors.
Can anybody tell me what are they and what their values?

Also,
After connecting homemade portable charger, my usb port doing problems. First it won't charge by connecting and cable that isn't the original charger, after factory reset it works without any problems.
I can now now charge it OK and also transfer files to the computer, BUT USB audio do not works constantly (5 seconds on 5 seconds off) and the same is the OTG. It seems the connections are fine (Ill re-solder them later). Anyone heard about a similar problem? What could be the cause?
Thank you!
Hello Bro. I have the similar problem: My phone got wet and when I was drying it with the heat gun, the components of volume + and - were deployed. I dont know if this can fix.
