[Q] Wireless charging + USB C audio? (without the official USBC audio adapter) - Xiaomi Mi Mix 2S Questions & Answers

Hello, I've bought this phone 1 week ago and it works really nice.
Some things I really don't like, like the chinese ROM (which I'm waiting for the unlock to switch to global) and the fact that we don't have the 3.5mm headphone jack.
I know that the phone comes with one adapter, but it might get damaged in the long run (the cable is not sturdy enough). I tried an USB 2.0 sound card connected to the phone using a USB C to USB 3.0 OTG adapter, but by doing that, the wireless charging stops.
In fact, anything that I plug in the OTG cable will stop the wireless charging.
So, I want to know if those cheap USB C audio sound cards will behave like the official USB C adapter, or they will stop the wireless charger.
Also, are those USB C passtrhu cables with a sound card working in this phone? Because with that, I could plug a wall charger and also get the headphones.
BTW, I know I could use BT, but thats not my idea.
Any feedback will be appreciated,
Thanks!

I think those audio jack/usb c cables should work.
The phone probably stops the wireless charging because the phone cant supply and get charged at the same time.
By using those cables you use the data pins for audio and the power pins for charging so it should work.
If you want to test this theory out use the original usb dongle and put it on the wireless charger.

The official headphone adapter is analog without a dac so it is not a usb device as such. It must use a dac already in the phone. Wireless charging works fine with it. I can confirm the plugging in a usb card reader stops wireless charging though.

I need a new retractable charger, any advice?

If I am to get a Galaxy S Phone - or any new phone for that matter - they require Micro USB. I have a bunch of Mini USB accessories. But for some reason, I am having trouble finding Micro USB products. Where can I find some good ones?
Questions include:
Mainly, where should I look to find a good micro USB to USB, for my car?
I occasionally plug my Touch Pro into my TV with my soon to be useless Mini USB to AV Out. What do I do now? I have seen some Headphone To AV Out, do they work?
Micro USB to HDMI? Is that supported across most phones?
What kind of charger does the phone (or most phones) come with? Is it one of those AC Adapters, with the USB plug plugging into the AC Adapter? But the USB Cord is like, one foot? Will I need a regular cable too?
Questions, questions!! So many!!

[Q] Micro usb + aux cable?

I've been looking for a cable to use in my car with my sII skyrocket for a week or so with no luck thus far. What I want is a single cable solution that plugs into the micro usb port on my phone and provides an aux out as well as usb out so I can charge and listen to my phone through my car. The usb would plug into a usb car charger and the aux out would obviously plug into the aux in on my stereo. I know it's possible to have one cable do this as I've seen docks that have this feature but I have yet to find a cable! I loved being able to easily charge and listen to my iphone with a single cable and hopefully someone knows where I can find one for my galaxy sII. Thank!
Does your car stereo have a regular 3.5 MM audio input? If so, just get a male to male audio cable and run that from your phone's headphone jack to the stereo.
I don't think there is such a cable because the Aux is an input that only take a signal from your device to the stereo, not the other way around. Usually those docks plug into the car lighter and connect to the radio using a specific radio station signal. Like burhanistan said, you should just buy a 3.5mm male to male cable like Retrak or Belkin and get a car lighter adapter for charging.
Yeah that's what I've been using but I would prefer to use a single cable to charge and play music. As you can see in these images the official samsung dock has a pass through auxiliary port with the only input being from the micro usb port so its definitely possible.
I might try and buy one of these and soldering in a micro usb cable to charge simultaneously but the skyrocket isnt listed under the compatible phones. Oh well my search continues...
Yea, sorry bud, the closest thing you're going to get is one of those Radio adapters that has a USB port on it, as well as the 3.5" male end.
I just checked on google for awhile and simply couldn't find anything. You can find these for the iPhone and I've used them, they rocked. Seems like the Skyrocket doesn't support audio out through the usb connector?

yeah would be nice..
Just bought one of these http://www.amazon.com/Samsung-Headset-Adapter-to3-5mm-Female/dp/B003W057FS/ref=pd_cp_cps_1
If it works with the skyrocket I'm going to solder in a usb cable as well to charge it at the same time. I'll let you guys know if it works next week.
i too would love something like this. i used the IMP adapter before on my iPOD it was great could charge and listen to music at the same time with only one connector coming out. seemed more clean as far as cabling went.
Well the adapter I bought does not work with my skyrocket... Oh well I guess I'll have to deal with a mess of cables for now

MHL + Power Adapter not Charging Device

So I recently got a MHL/OTG adapter off of ebay. The HDMI out and usb ports seem to work no problem. My problem is that when connecting my charging cable to the MHL hub my device isn't getting any power. I have no indications of my battery % going up. That means if I were to stream a movie onto my TV it would work fine but I would run out of battery fast. Does this seem like there's something wrong with the MHL adapter? Is my samsung battery charger not strong enough? Any help with this is greatly appreciated. I have done a bit of research on this and found mixed answers.
Actually... That's normal... An otg adapter puts your device into "power output" mode so it can power a flashdrive or other storage device... So the input/charging mode gets turned off.
Plugging your charger into the hub helps power the external devices so they don't kill your battery so quickly...
No. MHL 3 is meant to charge in parallel. Works on mine. It charges at 700mA only though, pretty slow. You can check the current by Synapse App + Skyhigh Kernel. I think you can configure higher charging rates as well(didn't try). MHL 3 is speced for 2A current.
Yeah... MHL works that way... But the OP says it's also an "OTG hub off ebay" .... So were not just talking about a straight MHL adapter... If it's an OTG hub triggering OTG mode on the tablet... Then it won't charge and it's not suppposed to.

Hi, I also have a MHL/OTG adapter like yours (MHL/OTG/Card Reader) MHL-HDMI works flawless but OTG doesn't.
A USB pendrive that works flawless with an OTG cable it doesn't recognized in the hub while MHL>HDMI it's working.
@xmilar can you please post the link to the MHL/OTG adapter you bought and while yours not charge, are MHL+OTG working simultaniusly?
Thanks!
I've looked into MHL adapters for my Tab S 10.5 and LG G3 but it would require multiple cables and if I replace either or both items and the new item uses a different MHL, I would have to spend more money. I ended up just buying a Chromecast that does the same thing and wirelessly. Best $30 I spent
Hello, I ve bought an MHL adapter, the one with usb connector to charge the tablet when using the mhl, anyway nothing is working. The tablet doesnt charge, and shows 2 times the following : HDMI Connected, then after one second HDMI disconnected, two times. On my Sony phone works with no problems. I have skyhigh kernel and stock rom.
Probably it's not MHL 3?
Sorry for the late reply, if is not MHL 3 why is it working on my Sony Z1 compact with 4.4.4 rooted also.
If the adapter works on a Sony device then its probably based on a standard micro USB connector. According to the wikipedia entry for MHL newer samsung devices use a propriety 11 pin micro USB connector for MHL. There is mention of a "tip" to adapt between 11 pin and 5 pin, perhaps you could buy one of these?

Micro USB to portable amp/DAC device issue with Samsung phones

So I got the S7, and I also own a premium pair of headphones and a portable amp/DAC as well. My headphones are the AKG K553 Pro, and my amp/DAC is the Oppo HA-2. When I connect an OTG micro USB to micro USB (both sides male) cable to the S7 and my HA-2, ALL it does is start charging my HA-2, which it's not even supposed to do. No music gets sent to it.
The ONLY way to get it to work is to use a regular USB to micro USB cable........ put the included S7 USB to Micro USB adapter (white) on the USB side and plug ONLY that side into the phone. It does send music via USB this way, but it still is charging the HA-2 when it's not supposed to, and also the adapter included with the S7 sucks because it doesn't lock in well so comes out very easily.
There has to be a setting or something I can do to change it so the 1st cable I used (micro to micro) actually works but doesn't charge the HA-2. If anyone knows, let me know. Or else I won't be keeping this phone for very long it seems.
Thanks!

Audio over USB

Has anyone tried an "Y" style audio and usb c charge cable with G5? Such as this one ( https://www.amazon.com/dp/B07176LPDT/ref=cm_sw_r_cp_apa_cxOHzb2QDXMWE )
I like to use my H850 in my car with a win sheild mount hooked to my car stereo through the top 3.5 mm headphone jack. I tough something like the above adapter might be nice and I could charge the phone at the same time.
I'm not sure if the G5 supports analog audio out over USB or if the above adapter has a cheap DAC in it as I could not find documentation on it. I have read elsewhere that the G5 does not work with USB DACs but that it does work with USB C headphones, which may be using a different standard.
Thanks.
Ok, just remembered I have a small USB audio "card" that I tried with my USB OTG cable. As long as I kept the USB setting on "power external device" it worked just like an external audio device. The card has its own volume up, down, and mute button which worked. It treated it as a "USB audio / dock" and responded to changes to that section of viper4android. The only downside is I am sure it draws more power (since the card has an LED light) and with this setup I cannot charge the phone.
I haven't tested the cards mic input or spdif output yet. It is based on the VIA Envy VT1620A chioset.
I use a USB headset through a USB-A to USB-C adapter and it works fine. I don't know about charging at the same time.
