No sound in Lapdock 100 - Motorola Droid RAZR

I just bought a Lapdock 100 and everything seemed to work; but I realize that there's no sound from the lapdock.
I've tried playing music and videos, having volume set to max, and it doesn't work. The player shows that there's a song/video playing but I can't hear anything.
I tried with a factory reset, using stock EU ROM, in case it was a software problem, but still don't work. And if someone calls me, the ringtone will sound from the phone; not from the lapdock (I don't know if it should be this way)
If a connect the headphones at the same time it's connected to the lapdock, then the sound works through the headphones.
I also have tried to connect the phone via hdmi cable to my TV, and the sound works, so the hdmi slot from my phone is not damaged.
Does anybody know what could be the problem? Could it be related to the fact that the Lapdock is from Verizon? (it would be strange I think)
Thanks!

Well I'm no android expert to say the least but I have a lapdock 500 and sometimes when I connect my phone the audio through the lapdock speakers is distorted.
The way I fix my audio problems is I disconnect the phone, play a song in phone mode, pause, connect the phone to the lapdock, and then when I start playing the song again on the lapdock it's fixed.
If that doesn't fix your problem then you should try hooking another device up to the lapdock to see if the speakers work. I know it might seem odd but turns out that any version of the lapdock product line can actually be used as an external monitor for any device with HDMI. All you need is an HDMI female to HDMI micro male adapter and an HDMI micro female to HDMI micro female adapter and with a regular sized HDMI you can hook up any device that supports HDMI to your lapdock.

3.5mm jack to aux + USB charger issue

I've got a USB charging cradle in my car which works fine.
I use a 3.5mm cable to connect my mp3 player to the car stereo which works fine.
I tried playing music from my HD to the stereo whilst charging and I get awful white noise and a constant pinging noise. If I take the phone off the charger it works fine. I can't find anything in the wiki or forums and I've seen some people on other forums with the same problem.
Anyone know what is wrong with this setup or I need a different spec cable (I guess its a standard stereo 3.5mm cable, so 3 contacts and I think the HTC one has 4 coz of the mic, but it works fine when I stop charging it. I guess it could also be a problem with the pins on the USB charger, but I thought the HD didn't have the extUSB connection.
I'm off to the USA on Sunday with a hire car so it would be really handy to be able to charge and play music!

[Q] Connecting my Phone to car stereo via a usb hookup, not working any ideas?

I had an ipod connected to my stereo through a cord that is run into the back of my glove box. The end is a USB connection so i figured my phone should work fine. When i plug it in it recognizes it and starts to charge my phone but on my deck it says no audio and i cant play any of my music. If anybody has some suggestions im all ears, Thanks!
The Motorola Vehicle Dock comes with a USB charging cable that has an inline 3.5mm jack out. You may need this or something similar to get audio out to your car speakers via USB.
Note: If you buy the Moto dock, do not buy it from AT&T. They remove the charger and package it separately forcing you to spend more money. Buy the Motorola packaged version instead.
Also, try changing the storage modes when connected. I believe Mass Storage is the correct setting, but could be wrong.
i dont think it will work. see those types or systems are formatted to work with ipod or a direct usb dongle.
i have the some type of thing in my svu but i have both usb and aux i just use the aux.
I connected Atrix to my Pioneer deck and it automatically recognized it as usb storage and played my songs as expected. With the car dock and cable it won't play music over usb, just through the 3.5mm jack.
Did you enable usb storage mode?

That's how I do it when travelling and renting cars. Works fine with 3.5mm jack if the head unit in the vehicle has an aux input.

I believe I already asked this!
I have the same problem with my pioneer deck. Instead of connecting USB for music ill just use Bluetooth from my phone to my deck and play music.

I'm having the same issue with my Atrix + a Pionner sound system on my car. The phone keeps on disconnecting and reconecting. No, I don't use the iPod/phone dock, but just the USB connection. The Atrix won't even charge because it's always enabling/disabling the USB.

[Q]SGP usb audio out and charger for car

Hello everyone. I am and android guy but I have and older ipod I use for my car that I would like to replace with an android player. I currently have a digital aux out to usb to charge and aux cable. With this cable the sound coming out is great. I have not been able to find any other players other then the ipod/iphone that sound this good.
Now i have a photon that when using the car dock has audio out but its not full raw out and dose not sound good at call like the ipod out set up I have.

Any imput that you all can give would be great.
Thanks in advance.

[Q] No Audio with HDMI Output

Hi guys, I read these forums occasionally, but this is my first time to post. My problem is (seemingly) pretty straightforward.
When I connect my Droid RAZR MAXX or ASUS Transformer to my HD monitor, the video displays fine, but there is no sound. I suspect this is because the monitor does not have any speakers, but I was hoping there would be a way to just let the audio play from the device. That's what my laptop does when connected via VGA (which might not support audio anyway; I don't know a lot about the different inputs/outputs).
Any help is greatly appreciated!
Thanks,
arnax
VGA does not support audio. Ive never done any of these but maybe they will work. Get a hdmi to VGA adaptar and then use an auxillary cord to hook up to monitor. Plug a headset into your phone to hear it that way. Or the simple solution get speakers for ur monitor.
As far as I know there is no way to use hdmi without the audio being played through the hdmi. Not just for phones but everything hdmi.
Thanks, I tried using headphones with my phone and that worked, so I suppose hooking up speakers to it should work too. I don't believe my monitor has a way to hook up speakers directly unfortunately...

USB Dac in Car Tablet strange problem

I have an Android Tablet with Android 6.0 installed in my car. My car has a aux input in the factory stereo so I've connected the USB dac (pictured in the attachment) in the DC power USB hub that connects to the tablet using the OTG cable. I further split the output of the dac to seperate the Mic and Audio. Every time the tablet wakes up from sleep the DAC is detected but there is no sound i get a buzzing like sound. If i disconnect the USB completely and plug it back in then it works perfectly. I left it unplugged and plugged it in after the tablet wakes up then it works fine. But for some reason if it's plugged in to the USB before the tablet wakes up then it gives that problem. Does anyone know what the problem can be? I forgot to mention it's connect via a short USB extension. One thing I can possibly do as a work-around is cut the power to the USB extension and have some kind of delay on it so it doesn't start up straight away when tablet wakes up.
Also, I have a high gain car mic connected to the mic side of the splitter but the mic just doesn't seem to work although the mic works when i try the DAC and same setup on my Samsung S20+.
Any help and suggestions would be great. Thanks
