Running Malaysk 5.1, but had the same issue on stock 4.1.1. I have two female USB connectors labeled "4G/USB", and tried both the included webcam, and my logitech C920. The red light on the stock webcam never lights up, and all of my video player apps have the camera icon greyed out, or they say no video.
What am I missing, is there a 3rd USB connector I forgot about? Is my unit faulty?
Thanks.

I uses to be able to watch TV show stream and my videos on my TV via the g2x HDMI out even with root and eb and cm7 then I went back to stock for a bit and the HDMI stopped working on the same TV using the same cable now all I get is a blank screen and no sound but it says playing on other screen so it obviously recognizes the cable... has anyone else come across this?
Hi guys I was wondering if it was possible to get the transformer to output music through the USB ports. I have a set of portable Creative speakers which have great sound and would love to use them with the transformer. They are powered and receive audio from USB
It is very possible, but you'd ave to add the device modules (drivers for the device) to the kernel yourself because it isn't native. I've been trying to get USB headphones working for a while.. :/

Got work usb audio on tf101 with CM10. Just kernel modules for usb audio are not enough to get sound from apps to be routed through the DAC. It's also needed to patch vertana audio driver.
I know it's been a long time but I just got around to rooting my TF101 and actually enjoying it. Has anyone done anything similar with speakers or headphones

Lollipop - Any Improvements?
Has anyone been able to get USB Audio working in a Lollipop ROM given the improvements to USB host?
So far, no luck for me:
KatKiss Lollipop 5.1 #21 ROM
JBL Pebbles USB Speakers connected to the dock
My tablet recognizes there is a USB audio device as the audio stops after connecting.
Also, disabling auto routing of audio to USB audio devices does what it supposed to do - so detection works.
Connecting the headphones out to the aux in of the USB speaker didn't work. Tablet speakers shut off but no sound in the USB speakers.
I could get it to work is powering the speakers from an AC charger and using the tablet headphone out to it.
Also, USB Audio Tester app works in that it can detect the USB device and it was able to play audio out of it (tested via connecting int mic to ext speaker mode and raising the volume bars).
To my understanding from the developer's description, that app uses non-standard interface to output USB audio.
The speakers work fine on Windows and Chrome OS without drivers so I was hoping it was plug and play.
Update:
I did note that I had to raise the in-app playback control volume bars first though to work in USB Audio Tester app.
Also, when connected to a computer and using the Aux In of the speakers, my phones and tablet can play audio.
Based on power draw of a USB charger I connected, the speakers use 0.6W idle and about 1W max.
Therefore, I'm thinking maybe it fails the USB enumeration in Android and the default 100mA is not enough.
Anyone know how to check the USB host enumeration settings?

Since we are talking about USB HOST, maybe it's important to use USB OTG cable, I reckon, as not all USB cables are equal. This has just recently struck me, because I used USB cable that came with my soundcard the other day. Its of great quality, sure, but I'm almost positive it's not OTG. My audiocard is externally powered, so on the other hand it might be just unimportant in my case...
USB Speakers of all sorts have generic DACs in them that require no special drivers and have to work out of the box on any system as long as USB connection and standard USB functionality are intact. Success stories of USB Audio working under Lollipop are rather abundant.
If USB Audio Tester works for you then USB Audio Player PRO should too, those are made by the same guys AFAICT. UAPP is no free app though, costs a sum, and sadly its proprietary driver(yeah, those devs apps use "non-standard interface") only works inside the program, one cannot watch Youtube or MX Player by using that... Compatibility list is on the devs site. My card, E-MU 0404 USB is listed as compatible for only RECORDING, not playback. Heck, I'm absolutely certain, I saw someone on some forum claiming they got same card totally working under UAPP and that wasn't even on Lollipop! Anyway, my trial and error continues...
I don't have a USB OTG cable for the TF101.
Instead, I'm using the keyboard dock that provides two USB ports.
It should be the same thing.
It is very good to hear that USB audio is working for a lot of people on Lollipop.
I've tried testing my speakers on more Android devices - my Nexus 5 and Samsung Galaxy Tab S.
Like the TF101, the speakers are detected as the OS switches over (no more audio out of built in speakers) but no sound out of the speakers themselves.
I'm leaning towards these speakers are not compatible with Android yet.
Sigh - non-standard standards.
First to say, this is a bit long, but explains exactly what is my problem and what am I doing, I really need help, please. Thank you,
Today I bought hdmi (Male-Male) cable and MHL 5-pin adapter for my Xperia Z1 Compact. And I have a really weird problem. So I set up everything the way it's supposed to be, connect hdmi cable to TV and mhl adapter, charging cable to adapter and then connect adapter to phone, also I set correct hdmi channel on TV. And, I get notification about MHL connected, but there's no any picture or sound on TV. Also, phone randomly stops charging, however mhl notification still stays and screen stays landscape, until I switch to another program on TV or unplug cable. Another weird thing, if I play any format of video in any player(even stock one), video stops every 4 sec and I have to manually press play every time(it's not performance issue though, I can play unoptimized games for qualcomm like GTA SA with same amount of framerate as if I played normally) and sound from video can sometimes go out through phone speaker(and it's not supposed to, instead should come as hdmi output on TV). And here some of the facts:
-My charger and cable normally works
-Without charger connected to mhl adapter, I dont get any notification, so charging part is fine
-If I unplug hdmi cable from mhl adapter, I dont get random charging interrupts, phone charges constantly
-I have stock 4.4 Kitkat Android, no system applications deleted
-My tv is from 2005, Panasonic, without mhl but has 2 Hdmi slots- 720p, in case TV means anything
I have 3 guesses that came to my mind: software issue(like bug or something), unsupported resolution(maybe if phone doesn't recognize TV's 720p and instead sets to full HD(but then there wouldn't be charging issue and probably video pausing issue too) and lastly, broken adapter(To mention, it's right type, 5 pin, so it could only be literally broken inside-loose, but it seems quality and if it was loose there would still be some kind of output on TV, during normal charging period)
Can anyone give some solution...? I can't find any similar problem to mine, so I have no idea what could be the cause.
Hello,
I've got MTCE unit (PX3) that I'm trying to install into Toyota truck. I've had another unit in previously and it had a reversing camera that was activated when the reverse was engaged by a dedicated wire in a harness. I've connected my camera to Video-In connector (H-5 on the attached harness). I can see video fine if I run AVID application, so this is working. What is not working is automatic engagement when I put the car in the reverse.
I can't seems to find a dedicated reverse signal. I understand that it may detect reverse through CanBus and I've connected included CanBus decoder to the unit, however it still doesn't work.
Am I missing something and what would the recommended troubleshooting suggestions?
Hi,
You are doing it wrong. You should not connect the video signal to Video IN of the unit. This way - the picture will show only when you launch the AVIN application. You should connect it to the CAMERA or REVERSE labeled plug. What is the G plug for ? Is it for a reverse camera or Car DVR ?
You can power up the camera (+12V and GND) from the white reverse light.
Thanks for the reply, however I can't sadly see any REVERSE or CAMERA labeled connectors on my unit. Plug G has microphone cable and that is it (see attached). Plug H has also a connector labeled DR-V and main connector has something labeled CCD-IN. I've tried plugging my camera to these connectors and sadly none of them seems to show camera feed when the reverse is engaged. Any other ideas on how I can get camera to work?

When you bought it, was it advertised as having this capability? If so, I'd try to get a refund. Mine (and most others that I've seen) that have reverse functionality have a dedicated video in line that's labeled as such.
See K 5 and 6.

Yes, the unit has reversing camera as an option and sadly the seller is less then helpful in resolving this issue. Having looked on the forums I can see that even when the camera is not connected the head unit should switch to black screen when reverse is engaged. In my case it doesn't do that. Does it mean that something is not working with CAN bus decoder? I've looked through factory settings and tried all options available for my car manufacturer and sadly they didn't make any difference.
Is there a way to test CAN bus decoder to see if it is working at all or not?
I have a reversing camera problem albeit a different one, that's been worse today. Sometimes after I finish reversing the camera image stays on the screen, frozen. I don't know if something's wrong with the reverse detection input or the camera video signal. I've had this with other units of the same model (KSP) or at least they were also MTCD PX5. My thought is to play with the resistances to the MCU. For now if I reboot it's back to normal.

Your reverse camera should go to the main power connector 5th pin(CAM-IN) and reverse trigger line should go to 6th pin(CAM-LINE).
Ideally your main power connector should have yellow video in connector which connects ground and 5th pin.

You've just made my day. This was exactly the solution to my issue. The wires were connected to some strange connector, however after I've rewired it to my camera everything started working just fine.
Thanks a lot for your help.
hello
I have exact same issue, with wireless camera connector , have yellow connector to ccd in and nothing changes maybe somebody could draw scheme how to connect to head unit , have same connector.
The phone (running the latest 13-beta and rooted) just can't tolerate USB-C wired ear pods. Audio drops out after a few seconds--even tho the app shows it's still 'playing'. Sometimes I have to stop the app, un-plug and re-plug the pods to get it to play in the first place. The notification area will show that wired headset is attached, but audio just won't stay on.
This morning the phone locked-up while trying to get them to work and I had to hard-reboot.
This happens with a brand-new pair that had a native USB-C connector, and an older pair I'm using with a USBC-to-miniplug adapter.
My bluetooth OnePlus pods work reliably every single time. Tried with two different audio apps, still no love.
Any thoughts?

Wow. You might be on to something! Under USB Preferences, "USB controlled by "Connected device" is selected and "Use USB for File transfer / Android Auto is selected--but greyed-out so I can't change it. Am I missing another setting or something...?
I Heard about this Problem before. But i think IT got fixed in latest stable Firmware....

Would some of you smarter people please help figure out what's going on? I/you can then file a bug report which won't result in it being closed due to their misunderstanding. The primary issue is that music stops playback when a USB-C adapter...
