logitech usb headphones worked with PX5 KGL - MTCD Android Head Units Q&A

just wanted to report that neuron player outputted to my logitech headphones when connected via USB.
and this time it had not hiss or any of the annoying sounds I get from main unit, so now I am thinking of getting proper DAC, and AMP to power the speakers from that rather than the unit itself.
few things I noticed, is that only this players output to the USB, and even then it does not respect the volume control, as that seem to be for normal output, but I might be able to make it work.

tested bluetooth, and I can get output from usb instead of main stereo.
volume is way too low, although I can control it from my phone (media volume) so it means all what I need is an amp now and software tweaks to make everything working

Bluetooth CAR radio with HTC TP

Did anyone try this? I'm thinking of buying a new radio WITH bluetooth..
IF the bluetooth radio stuff works, then tomtom/music could go via my HTC which would be awesome... or is it possible to play MP3's via an USB outlet, or have some auxout to my htc?
A few months ago, I bought a head unit (Dual XHD6425) that has front panel aux out, usb, and bluetooth. I originally got it for its 3.5 mm auxillary out for my ipod, but I then bought the add-on bluetooth module and started using my cellphone and now my Fuze. Bluetooth audio streaming (A2DP) is much more convenient as there are no wires to deal with. The TF3D music program supports AVRC so you can use the unit's fast fwd/rewind/stop buttons to control playback. Tomtom also routes its audio through the bluetooth interface as well. Of course, you also get hands-free calling, which is great as I usually forget to put on or turn on my bluetooth headset when I enter my car.
My head unit could also play music from USB sources (name hard drives, etc, but strangely not ipods). The unit was able to read from the Fuze since it can mount itself as a storage drive providing access to the microsd card. However, in this mode, I'd have to scroll through songs using the unit's interface, which was not very easy to navigate. Still, I can use the USB port to charge/power devices if I needed to do so.
^^^Ditto what he said^^^
My Xterra has a Pioneer single din headunit with built-in Bluetooth. A2DP streaming works great, but sometimes sounds a little tinny or washed-out. If you have added a subwoofer to your vehicle then get a headunit with an independent subwoofer level control. Some songs will be very bassy, while others will need some added punch...this can be adjusted very easily especially with a remote-mount bass level knob.
You can also sync your contacts over to the BT headunits and set speed dials as well as picture dials in some cases. My Pioneer replacement will be a double din 7" touchscreen dvd player with BT. Make sure it has plenty of audio controls/adjustments...digital time correction is a nice feature to help balance sound and set stage.

[Q] Change setting for audio jack

Hi! I just bought an FM transmitter that has a 3.5mm audio jack input. I connected my Samsung Galaxy S but I'm unable to transmit the music being played on my phone to the car stereo.
I increased the stereo to a very high volume and was able to hear some music, with static and almost can't be heard.
My guess is that I should change the setting somewhere (similar to my old N95 phone where it would prompt me to select to which mode to choose: Headphones, Music Stand, etc.)
Can anyone help?
sounds like the headphone cord isnt in the jack all the way. Or your transmitter is bad. Or you are trying to transmit on a frequency that is already being used by a real radio station.

hi, thanks for the quick reply.
I checked and the jack is connected.
The transmitter works because when I play music from a USB stick plugged in, it works.
Same as above, using the same frequency but from a USB stick, it works
Are you using a dock? Did you check your media volume settings?

[Q] USB Headphones

My headphone jack stopped working a while ago. Haven't been able to fix it but I do have a USB Headphone but it doesn't work when I plug it into my Transformer. Any fix or mod for that? I also have a bluetooth headphone but streaming seems to suffer whenever I use it. thanks!
Transformer's kernel does not support usb audio so IMO without deeper modifications you're not able to use it. I also have a bluetooth headphones and on A2DP profile it works great.
You could also replace the board with the headphone jack.

So is there a way to have audio simultaneously on Bluetooth and Stereo plug ?

Hi all.
So I want to have audio output to both, simultaneously, to a remote Bluetooth-receiver (which is on the other side of my bedroom's wall) and to a stereo 3.5mm connection next to my phone.
Right now, I can have audio to one, but not both (Bluetooh, OR, 3.5mm).
After much searching, I am 50% happy using the app Turbo Alarm because it can play audio simultanously to my Bluetooth receiver and the phone's loud Speaker, but NOT to the phone's 3.5mm plug (silent).
Any thing you know that can do the trick ?
Thank you all.

The hardware in your device is designed to only output audio one way or the other, not two or three. It's a limitation built into the hardware, you aren't gonna change it.
There is, however, a solution to your problem, it involves external hardware.
You will need a 3.5mm Y cable and a Bluetooth audio transmitter, plug the cable in your 3.5mm audio jack, connect whatever device you were gonna run via audio jack to one side of the Y cable, connect the Bluetooth audio transmitter to the other side of the Y cable.
This will allow playing audio to both but it won't allow them to listen to different media, they will hear both receive the same audio.
If you want the listening devices to be able to play different audio independently, then you'll have to consider other hardware such as wireless flash drive, it can stream audio to up to 8 devices and stream video to 3 devices, each of them watching or listening to different things independently of each other.

Apple USB-C to 3,5mm dongle volume

Hi there,
I'm using the Apple USB-C to 3,5mm dongle, but due to some generic Android USB audio thing the sound is pretty low. I have to nearly max my volume to get some decent sound out of it. However I've read on Reddit that the app "Neutron music player" appears to be able to bypass that and get a much higher volume out of the dongle.
Does anyone know a method to bypass this volume restriction(?) on a systemwide level? I'd prefer to use Spotify for my music in stead of that app.
I'm rooted so it wouldn't be a problem if the proposed method would require root.
Thank you guys in advance!
I was having the same problem w/ the Apple adapter from AUX to USB-C and, I tried the Neutron Player and it actually worked. The problem I was having, and that this pretty much fixed, was that the volume to my headphones was to low while listening to Music. Now its much louder. Thanks for the suggestion.
