I have some cheap Samsung USB Type C Earbuds. When I plug them in, I get a notification that says the Pixel is charging them(!) and the connector starts getting hot. This doesn't seem to be ideal.
No sound is played. Has anyone had issues with audio over USB?

I have a strange issue after installed my Nexus 7 as a car stereo setup in my Subaru (see setup blow)... Whenever I turn up the volume, specifically the subwoofer, the USB system basically "resets" itself. As if, I unplugged and plugged it back in very quickly. At first, I thought my USB DAC was bad, because I plugged my audio feed directly into the tablet with no USB devices connected and all worked fine, but if I have my hub plugged in and then the reset happens (with audio from tablet still), the reset still happens and my OBD2 adapter (USB) brings up torque. I plugged that same USB DAC directly in, with no hub, to my OTG cable and used its audio feed, same issue. I thought maybe the voltage drop was too harsh and causing issues with my charger, so I ran a 120v usb charger setup (like a factory phone one) with an extension cord to my vehicle to isolate its own charge system to the tablet with the same results. OK, Maybe it is just vibration? (forgot to note: subwoofer is freeair, laying in the back seat... still testing, box isn't done yet, so the vibration level is next to nothing currently.) I grabbed my usb cable system with the volume low and shook the life out of it... never did the reset. Again, only when the subwoofer volume goes up and anything is plugged into the USB port on the OTG for external devices does this ever happen.
The Setup:
I have a dedicated 4A 12v-5v charger and it seems to charge the tablet fine. I have a 90 degree charge adapter in place. I also have an OTG Cable so I can hook up USB to my dedicated USB hub that I have a "backup" power cable plugged in (into the same 5v charger the tablet is).
Audio chain wise, I have plugged into my USB hub a USB DAC. After that, a noise blocker. From there, I wired in a potentiometer for volume control. From there, it goes to the 4 channel amp and the mono subwoofer amp (which also has a dedicated volume controller that came with the amp)
Power wise, I have a dedicated run of "oversized 4awg" (basically, 6 awg wire) from under the hood and no more than 5' of cable to a fused distribution block, then to the amps. I also have a ground wire of the same size that from come the battery ground that all amps connect to (as well as chassis, so about an overkill of a grounding system). The factory wiring harness was spliced into for connection to a relay that feed from the constant on factory wire, feeding the 5v usb charger and the remote turn on trigger for the 2 amps (so it shouldn't be overloaded at all).

I'm pretty stumped at this point. Any ideas?
Wiring can be a *****!
You could replace your right angle cable and OTG with this one item: https://www.amazon.com/gp/product/B00NSBVNCM/ref=oh_aui_search_detailpage?ie=UTF8&psc=1
My USB3 hub works pretty good. but it's not at rock solid as the USB2 hub it replaced. Hubs can do some weird things when they don't initialize when the tablet want or thinks they should.
How does the subwoofer volume knob connect?
Does the the same happen when you turn the other "volume knob"?
How are the 2 amps connected to the DAC?
I'd guess offhand the DAC doesn't like whatever "feedback" it's getting through the noise suppressor from the potentometer.
What's the reason for it? You should be able to adjust your system volume through the tablet, especially if the sub amp has it's own gain.
fr4nk1yn,
-Just ordered that OTG cable. Was going to try and make my own, but if that one is proven, good enough for me.
-Agreed on hub, but I did try going direct to OTG cable, bypassing hub, and had the same issue.
-Subwoofer volume knob has its own RJ-11 phone cable to the amp. I took it apart, its using only 2 wires out of the 6 to the potentiometer inside, so pretty simple. Not sure how it works at the amp itself, but standard subwoofer volume knob on an amp, far as I can tell.
-Other knob can be cranked, seems fine, but more testing would need to be done. Soon as subwoofer knob is cranked with the volume know all the way up (or close), it triggers really quick.
-Does Dac > Potiometer > Amps (soldered wiring together, 4 channel amp has 2 specific connectors and sub has pair of RCA)
-Potentiometer gives a much better feel, very response in comparison. Having to find a volume "knob" on a tablet requires vision, taking away from the driving experience (and safety!). Don't like if the tablet has ANY delay in that control as well. I'm just old school, I guess.
Thanks for the help!
Last week I wanted to plug in my phone into our shop's stereo, using the the official included USB-C to 1/8th headphone adapter. I plug in the phone, fire up my music, but the audio continues out of the phone's speakers.
So I unplug and replug in the adapter, and the aux cable a couple of times with no luck, even restarted the phone to see if that would do it.
At that point I thought that somehow the adapter was damaged, so I ordered a replacement (making sure to get one with a DAC [sidenote: **** any manufacturer that makes you not only have to get an adapter for headphones, but makes you have to get a SPECIAL adapter])
No dice with the new adapter.
I went a couple of days not really worrying about it, the phone charges just fine, like it always has, so I didn't think it was a hardware issue. I thought it was just bad luck with these stupid, terrible, superfluous, awful adapters.
But today I had to pull a file off the phone to my computer, using multiple known good Type-C to USB-A 3.0 cables.
Phone says it's charging, but I didn't get the notification to select USB mode, and USB ADB debugging never showed up.
Windows is constantly making the device connected, disconnected sounds, and device manager is showing me an "Unknown USB Device (Port Reset Failed)"
Is it possible that somehow the data connections on the port on the phone are damaged, without it affecting power delivery? I have no idea how that would work, Like I said, it charges just fine, and all my cables feel pretty secure when plugged in, there's no play or wobble and I don't know what to do to troubleshoot it further.
You can try to clean the port
I have the same issue. Ive requested a replacement aux dongle from Google and still no go. It charges fine, connects to my computer fine adb, data transfer etc all work, only for music it continues to play from the speaker even when connected.
Yes it's possible for the phone to get power but have no data connection it's happend to my Nexus 6p I paid for the insurance so I had to pay the deductible to replace I have had some data issues with the pixel 2 xl but always seems to come back after a few days could just be a dirty connection since I work construction and some times gets very dirty.
But I'd be careful of what cables you buy when they are usb a to c but seem to have no issues with c to c
I have the same problem and are trying to work with Google for a fix. I have tried everything and they are pretty useless. I am now requesting a new device as I'm still under warranty.
Hi, I picked up a pair of type-c earphones from AliExpress for my Mi A1 which is running Pie with the March update. However, my phone doesn't detect them and no audio is sent to them either. Any ideas?
Not all TypeC speaker/earphone devices are the same. I also tried that with a friend's TypeC earphones and it didnt work. I attached a USB DAC Dragonfly Red via an OTG adapter (Type C Malr to Type A Female) and I got audio out from it.
It seems you'll need a type C headphones that has a built in USB DAC or use a USB DAC in-between like I did.
Some type C earphone are just wired to take advantage of the additional wires in USB3 TypeC and so the phones output the analog audoo through these additional lines. This also makes them incompatible with other brands too. Meanwhile, the A1 has a USB2 TypeC and so also only has the 4-5 lines of microUSB B.
Bottomline: use the 3.5mm audio out of the phone or use a USB DAC to output audio thru USB TypeC.
I grabbed a two pack of some dongles to convert Type C to audio, they work for standard iPhone headphones, but not if I plug in an aux cord . The phone recognizes it as headphones attached but no sound every comes out.
Any idea how to fix/have you guys used any brands successfully with aux cords?
Same problem for me.
Any helps?
Thanks
Does the dongle have a built in dac? If not try unplugging the dongle, go to settings, enable otg storage, then plug in the dongle. I need to do that for my dongle
Way too many times I'd be watching youtube or streaming with headphones and the battery will get low and I have to unplug them to charge
Heyyo, I've tried one and they never charge my X2 faster than it drains... It could be related to LeEco's kernel haxxs and how it's not using the full USB Type-C standard...
I've tried many type c Headphones or type c to 3.5mm adapters and the mic section of the headset never works.. Has anyone got it work?
