Sound while plugged into car charger

Hello!
When I plug my Touch Pro into an active Adapt carholder the sound output of my touch is forced to the charger (no sound output anymore on my mobile).
Is there any way around this? Any registry setting?
Or maybe remove some of the pins from the mini-usb connector on the charger?

Try getting HTC's official dongle which plugs into the USB port and gives you several connectors;
USB for charging
3.5mm headphone socket
2.5mm mini-headphone socket
USB for HTC's original supplied headphones
If you use this, you can plug in headphones at the same time as charging. I use it to route sound through to my car stereo so I can use the phone as an MP3 player and Sat-Nav.
If you don't use the headphone sockets, sound still comes out through the main speaker on the phone.

Hmm I have one of those, but the car charger I use is a slide-in holder, so there won't be much room for the dongle

Microphone unuseable when plugged into stereo
I use the usb dongle adaptor in my car to push sound through the stereo, however this disables the HTC Touch Pro microphone so although I can hear people calling in (through the car speakers) they cannot hear me.
I think it is because the phone thinks the headphones are plugged in and that I'd use the headphone microphone.
Does anyone have a tweak which would allow the phones microphone to remain in action when using the dongle?
Many thanks

I don't have that problem at all, my phone's microphone works fine while using the USB dongle with a 3.5mm jack plugged into it, connected to my car stereo.
Are you using HTC's official dongle, the one with the 3.5mm, 2.5mm USB power and USB headphone sockets?
It works fine for me!

USB sound output? USB-splitter for charging and headphones?

Might sound strange but I would like to connect a USB headset and charging cable through the microUSB port.
Does the Desire output sound through the microUSB? Will it allow me (if I find the right cables and splitters) to use a USB headset for calls while charging the phone?
Very greatful for all the help I can get.

The Desire has a dedicated audio port, the 2.5mm jack port near the power button. The microUSB port is a standard microUSB, not an extended HTC version, so no audio through it.

You mean 3.5mm

Yes, sorry

How to connect Pixel 2 to Fiio DAC/AMP?

Looks like the bundled male USB-C to female USB-A adapter's intended purpose is to help users transfer their data from old phone to new Pixel.
However, I have a Fiio Q1 Mark II DAC/AMP that has micro USB as input so I used the bundled USB-C to USB-A adapter to connect my Pixel 2 to this DAC but audio still comes out from the phone's speakers.
How can I output the audio through USB-C? In developer options, I select USB Configuration to "Audio Source" but nothing changed. Or I need to use a USB-C to micro USB cable?
To clarify things, here is my configurations: Pixel 2 <-> bundled USB-C to A adapter <-> normal micro USB cable <-> Fiio DAC <-> Headphones (3.5mm jack)
Thanks.

You should be able to use the combined line-in/line-out port instead of the micro-USB, though this would require you to first use the bundled USB-C to 3.5mm adapter. This is problematic if you're not rooted since the Google DAC has terrible distortion, and can only be fixed with root. The setup would be:
Pixel 2 -> Google USB-C to 3.5mm DAC (digital gain <75%) -> 3.5 male to 3.5 male -> Fiio Q1 DAC using 3.5mm line-in -> Headphones
A USB-C to micro-USB cable may work.

Thanks for your reply.
I have finally made it work. USB-C peripherals must be connected in order. You need to power on the DAC first, connect the micro USB input then connect the USB-C to the Pixel last so the Pixel would recognize the device on the other end.
Another question raised. I have also tried connecting Fiio DAC to iPhone via micro USB to Lightning cable. It worked instantly. iPhone wouldn't let me adjust volume on the phone. Everything was handled by Fiio. Which I think is the correct way to do it since iPhone is just sending digital signal to the DAC and let it do all the work.
But with the Pixel, I'm still able to adjust volume on the phone. I wonder why the phone could do it since it should not do anything with the digital audio signal. I also would like to know how loud should I set the volume at phone and adjust the rest at the AMP.
Also, Pixel's battery is draining fast! Because USB-C supports charging connected devices. I'm not able to disable USB-C power output. The LED light on Fiio indicates that it's charging. The reason that I didn't want to use Google's USB-C to 3.5mm DAC is because the distortion issue. I believe Fiio DAC is much more powerful and audio quality is better.

Apple I believe uses a line level, the Pixel's is amplified so you can still control it on the phone.
I'd recommend hopping over the the Pixel 2 XL forum, there are technical details that might answer your question. Objective sound measurements.
Regarding the Google DAC, the distortion goes away below about 75% digital gain. In that chained setup, you'd be looking to send as pure a signal as possible with little to no digital gain to the Fiio, which would then cleanly amplify it for playback.

USB audio and charging possible?

Is there an adapter that lets let get audio from the USB port and also charge with the Pixel XL?
I use my headphone jack for something else (PluggyLock) so I want to get audio from the USB port. Tried a couple of adapters from eBay and Amazon, none of them work even though they claim to support the Pixel.
I see Google make a USB-C to headphone adapter, but it doesn't support charging. Kinda useless for long trips with navigation running.

Although I'm not aware of a working solution like you have described, you might try a workaround using a Bluetooth receiver with a headphone jack. Here is an example.

I am considering bluetooth, but it's fiddly and most of the cheap adapters have poor sound quality (buzzing, no AptX support).

Question Using wired headphones

I have a Galaxy S7 FE and I have a pair of Sony bluetooth noise cancelling headphones. I can pair the headphones with bluetooth and audio works fine. But sometimes I go on business trips and long flights the battery in the headphones die. In this case I want to connect the headphones using a wire. The headphones have a 3.5mm female connector as well as USB-C. I have tried connecting the headphones directly USBC headphones to USBC tablet and audio doesn't come out of headphones (just tablet speakers). I have also tried using this device and using the 3.5mm cable, still no luck.
Does anyone know how to connect headphones to the tablet with a wire, either 3.5mm or USB-C?
Appreciate any advice.

I am using this one with my Tab S7 FE. Charging and Headphones work even in combination.
