Hi
I'm using Android Auto with a Note 9 connected to a Kenwood DNX9190DABS head unit. Everything works well.
My understanding of the audio process involved is as follows: the USB-C output from the phone is digital and by-passes the phone's DAC. The crucial element in terms of audio quality is therefore the head unit's DAC..
I'm thinking of substituting another phone for the Note 9 so I can keep the Note 9 as a phone and therefore not need to connect it each time I use the car. My plan is to buy a cheaper / older phone to use as a dedicated music player in the car with the only criterion being that it works with Android Auto.
My question is this: is the audio quality of digital output from USB pretty much the same whatever the phone with the head unit DAC remaining the crucial element or does a higher end phone have better digital audio output?
Thanks.
Have you tried AAGateway from Emil?
I'm using Galaxy S3 as gateway and use my S10 over wifi hotspot, the audio is the same quality as USB directly
It doesn't matter what phone you use, as long as it's compatible with the USB DAC (not all are).
The phone won't be processing the music.

hello, I did this stuff here Alfa Romeo & Galaxy Tab integrating seamless the tab and my dashboard.
The overall result is very good, except for the audio volume, and being not an audio expert I fear that this is an impedence problem.
To make it very short, I just connected the headphone plug with the inputs of a 50W ("rms", real 50 watts they say, not fake 50w as standard OEM car audio), a kenwood KTP-500 thing. The problem is that the max volume is VERY VERY low in comparison to whatever oem standard ****ty car audio device, and that is quite impossible to me, and also for audio tuning shop owners I enquired for some advice.
So I think I need to convert, somehow, the signal to be good for the amplifier.
The amplifier has got switch between "low gain and high gain" but it does not change that much.
So I've got 2 plans to get an at least "normal" audio volume, amplifying the signal with some kind of "line amplifier", or find a guy (perhaps here? ) who can explain me the setup error, so that I can fix it. Shouln't be that difficult, but I'm ignorant in this stuff, and surprisingly, neither do know the people that works at kenwood/alpine/whateverBlingBling-audio shops in my city.
I also tried to debug my installation connecting a PSP, some other phones, a small television, an old cd player... all with the same low-volume result. So it's not a GalaxyTab (p1000, the good 'ol one, since it's exactly 2din fit) issue, but more general, having knowledge in audio signals may help...
So what is the point with connecting directly an earphone jack to the inputs of an amplifier? It's so amazing after 1 year having the tab as audio unit, it's a shame to have this volume issue è__é thanks for any clue
p.s. the audio quality is excellent, anyway, no buzz, humming or distortion. It's only... too low
I have the same problem, the volume is very very low, especially in a telephone conversation using speakers. However the sound quality is excellent. The problem is that you can not have a conversation without a headset ,when youare in a opne place.
I have the official HTC car dock, and while it fits great, looks great, and does its job, the USB cable doesn't seem to give me any capabilities except charging. Is there no USB audio capabilities through this cable? I tried connecting the phone while in the dock directly to my USB-in on my car's head unit, and there was no sound.
Is there a better way? I'm on CM10 and Bluetooth is a bit wonky, so any alternatives to connect my phone to play music through my stereo would be great. Any of them except using the headphone jack to connect to the AUX-in on my head unit. I want something line-level.
unfortunately there is nothing line level on android to my knowledge. everything is done on a line-less level: IE bluetooth. and even then if there were a line level way of playing music you're on CM10.1 so its going to be even more iffy
Here is my set-up:
A Vivo LTV42FHDN 42” Full HD TV (2x HDMI inputs, 1x RCA stereo audio output, few other audio and video input connectors, and a set of really crappy built-in speakers)
A Logitech 2.1 Speaker system connected to TV's RCA audio output
An old DELL XPS M1330 notebook running Windows 7 hooked up to the TV via one HDMI port
A new Chromecast I’m trying to setup connected to the other HDMI port.
When I watch TV and switch to the HDMI input of the PC I get audio through both the TV’s crappy built in speakers as well as the much better sounding Logitech Speakers. However, when I switch to the Chromecast I only hear audio through TV’s built-in speakers. I have connected other PCs and tablets through HDMI before and from what I recall, sound always came out external speakers.
Is there any reason for the PC and Chromecast to behave differently when connected via HDMI ? I tried both HDMI ports, went through TV's audio settings (which only has very few settings like bass, treble, and some sound profiles), but couldn't get the chromecast to output audio through external speakers.
Does this mean Chromecast doesn’t support somesort of an HDMI specification/standard my old PC does, therefore the TV can't split and reroute the audio ? Is there any way to get around this without buying new hardware ? Other than audio, rest of it works great ! For me spending $50 or so extra on additional hardware really defeats the purpose of buying a Chromecast, because for that price I could've bought a DLNA enabled media player.
Any help appreciated. Thanks.
I'm not sure about your LG, but my Sony correctly re-routes audio from Chromecast to SPDIF (optical) output connected to AVR, so the Chromecast isn't a problem. I'm not sure about analog RCA output though.
Just go through your TV settings again. There must be an option burried somewhere in menus.

Thanks for your reply, I did go through all the settings on the TV and even read the manual. But couldn't find anything there. Its not a very high-end TV, hence no optical output, all I have is that stereo analogue output.
Few minutes after posting I again connected my new notebook, and a Windows 8 tablet, audio works fine with all of them. But the Chromecast just doesn't work the same way. When I tested I connected all devices to the same HDMI port and didn't change anything on the TV, all I did was plug one in > test > unplug > plug the next one in > test etc.. that's all.. the fact that everything but the Chromecast work has to mean there is something different in Chromecast's HDMI signal.

Try switching the audio output in whatever application you're casting from to Stereo.
If Chromecast is sending multichannel audio, your TV might be smart enough to decode and play it on its speakers, but not smart enough to downmix to the analog output.

Hi,Were you able to resolve this problem? Chromecast works great except for this exact same annoying problem. Also have the same TV. Thanks.
My current daily driver just keeled over a few hours ago so I need to order a new phone, was wondering how the audio quality on the USB dongle is and how long the dongle will last. I'm using the Apple 3.5mm Earpods if that matters. If the dongle is garbage I might order a Lite instead, the most intensive thing I do is play Hearthstone and run browser + 2 social media apps in the background anyway.

This is my first dongle phone and I was a bit sceptical, but the audio output over the dongle is excellent. I'm using the Sennheiser CX3.0 earphones and the output is much better compared to my Nexus 5 which was pretty good to begin with.
The thing that bothers me are the dimensions, position and placement of the port + dongle... When you use the dongle, the jack which is the heavy part of the earphones sticks out of your pocket stressing the dongle USB joint and I don't feel comfortable putting my phone in my pocket using my earphones out of fear that I will rip the dongle in the USB join because of the headphone jack's weight...
So, I am currently bypassing my car's infotainment and amp to run a high end audio system. Reason for this is the stock CMU and Factory Amp just don't cut it for power, bit-rate, and sampling compared to a quality aftermarket system. I'm currently running an OTG that goes to a Digital to digital converter converting to optical audio straight to my DSP.
I'd LOVE to have Android Auto working while being able to send audio directly to my own system rather than the car's. But Android Auto entirely overrides audio outputs from the phone and forces audio to be done through the connection even if wireless. (so that I'm not using the stock amp which is integrated into the car's MOSTbus and a royal pain to work with, and double amp set ups are horrible for quality and tuning audio)
Has anyone figured out how to change the audio output of the phone/android auto to be separate of the Android Auto service while retaining the Car's connected Android Auto features/controls but using the separated audio stream?
Hi. Same problem
