[Q] headphone amp? - Droid RAZR M Q&A, Help & Troubleshooting

when I connect my razr m from the headphone jack to the aux input on a car radio via a cable, the output is very low even with both devices turned all the way up. Will a headphone amp work, or any other options? Thanks

How does it sound with headphones? Maybe there is a problem with your aux cable? Are you using the stock music player, check the equalizer settings. I get plenty loud when connected to my aux, I would double check everything before buying a headphone amp.

I agree with this. Now, if everything is up and fine, then yes, an amp would help. Personally, I use a Fiio E17 (not with the RAZR M, but with an iPod Touch). I have room to spare on that volume dial.

Vibrant Sound Out + Car Aux In

Hi guys, my 328i has a built in Aux input. And it works great with my Vibrants 3.5 output jack. The only issue I have is, the volume is just not as loud as It is listening from the mp3 CD. The volume for both the phone and car is at full volume.
When I usually listen to mp3 cds, the sound goes up way louder. Is there a way to hack the phone to output louder through the 3.5 jack? Or if any of you have the 328, is there some option to do that?
I don't know about mp3 cds but as for official cds bought from the store, they are definitely a lot louder that the phone through aux jack. Same deal with my g1 before I got the vibrant.I'm sure once the rooting and custom recovery is all sorted out and we start getting some custom roms, the devs will include volume hacks just like they did for the g1.

I'm quite satisfied with the volume. If you need to blow your ears off boost up the EQ.
Actually, it's really weird. Through headphones I can equalize my Vibrant and iPod to sound the same, but through AUX, the vibrant is quieter (Same volume settings). Really makes no sense to me. It has to be something with the equalizer...
Edit: But it is in no way quiet. I have to turn up my car stereo by like 4.
Try a different cable or a higher quality audio file.
I play songs between 192kbps to 328kbps and have no problems. The volume is at the same level since I used my mp3 cd.
appreciate the inputs, i'll look for the equalizer on the phone.
Have you guys tried sending the audio thru bluetooth audio enable car radio? Pretty cool no cables needed
I can even listen to pandora and send the audio to my stereo

whoa, i'm going to have to try this out. any advice?
I have the Pioneer Z110BT Navigation and it has bluetooth audio. Just pair your Vibrant to the Pioneer then play any song on your vibrant using the music player. Click options then "Via bluetooth".
Then go to your stereo and click on bluetooth audio. Voila! Streaming music from your Vibrant to car stereo. The sound is also great!!
Not to hijack this thread but my one complaint of the phone is how low call volume and audio volume are.
Everythings turned up to max and this phone is roughly half as loud as my MT3G is set at 50%.
I have a Sony xplode and play through Bluetooth, I get great sound.
I have no issues with call sound or ring levels. I actually have to turn it down sometimes because its to loud.

I built a custom cable to connect the headphone jack to my Pioneer's IPBUS connector - it works great, and is very loud. I keep both the head unit and phone's volume on half way, and depending on the song I may have to turn it down, too.

Is there a way to improve the audio output?

I like using my phone as an MP3 player but the audio output is horrible when I connect it to the Aux connector of my car. I've tried double twist as well as the original player, double twist is a slight improvement but not anywhere near quality audio. Is it the phone itself or is it the application?
BTW: headphones sounds ok.
Mine sound great over 3.5 and bluetooth regardless of the app or accessory.

weird audio problem

When I connect head phones to my x10a the audio is distorted badly. it doesnt matter if I connect headphones or a aux cord to the phone to listen to music in the car the audio is distorted and the music app I use (pandora,last fm,slacker) all become unlistenable. Is there a app or a hack I need to do? I already did a warranty exchange with the phone.. any help will be appreciated.
Do your headphones have a microphone on them? That happened to me as well, so I got some headphones without a mic, and now it's crystal clear. I have altec brand headphones now and they are awesome. If you get new onss, I highly recommend getting those.

Again. Questions go in Q&A

Am I the only one here who tries to use the Epic in a car, in a dock...??

Is anyone else trying to use a dock in their car to listen to music??
I'm on CM7 and when you use the dock in the car.....it removes all bass from the audio stream. Unless my car for some reason doesn't go through it's own amp. when using the "aux" in connection.....
I'm so frustrated at the moment, I bought a phone with all these cool hopes and dreams..
now 1.5 years later, it's ALMOST perfect (no thanks to ****sung) (thanks to DEV's!!) but I go put it in the car dock and the sound is just awful
Just wondering if anyone else has had any success ..
Using stock CM7 kernel or Shadow? From what I understand, bbelos was able to crack the code with Shadow, but maybe the devs were able to port it over to the stock one...

I'm using Shadow.
The dock audio works, it just sounds awful, no bass very tinny.
I should add that if you take it out of the dock and plug in an audio cable to the headphones jack and into the aux in of the car it sounds wonderful, full bass great lows and awesome highs.
From what I understand this is something that samsung made the dock do. What a horrible idea on their part.
I use my CM7 Epic in the car all the time. I don't even use the car stereo anymore. When I started using CM7 and realized the audio redirect doesn't work I went back to using what I did before we got Froyo. My stock car stereo doesn't have bluetooth so I bought this:
http://www.amazon.com/BlackBerry-Remote-Stereo-Bluetooth-Gateway/dp/B00170KUM0
It's a bluetooth gateway that uses A2DP to transmit the audio. I also use Tasker to automatically turn on bluetooth when I put the phone in the dock. The phone connects within a few seconds and everything works beautifully. It actually seems to amplify the sound some when using the gateway. I see it's like 90 bucks on amazon now. It was 30 when I bought it so i dunno. You could probably find one cheaper somewhere. But anyway, that's what I do and have had no problems.
using the bluetooth gateway is a good idea. though, imo, A2DP lacks decent quality. I have really only done A2DP streaming with Kensington's LiquidAUX receiver and the Motorola S9 headphones. I would be tempted to try the BB receiver if it was cheaper.
Samsung really dropped the ball on the desk dock. no data when the phone is in the dock while connected to USB? WTF Samsung. I would love to put another one of these in my car if it worked correctly. does the real car dock have the same issues as the desk dock? I am definitely not gonna pay $30+ for a car dock for a phone thats been out 18mo.

I actually have a bunch of these, however it just isn't the same sound quality as hard wired.
^yes I agree, BT (A2DP) sound is technically compressed, and combined with a poor DAC, just isn't going to sound as warm as coming directly from the headphone jack (where the DAC has already done its work).
I just spent some time screwing around trying to find the differences in sound between the phone mounted in the dock and using the speaker out, streaming the music over BT with my Kensington LiquidAUX (outputs to 3.5mm), and plugging directly into the phone (w/ Voodoo sound).
Handsdown, best was when hooked directly into the phone. Second place went to the dock, and third was BT. I've just come to the conclusion that Samsung just didn't put any effort into this dock, and the actual DAC inside the dock, just sucks. This is all just going on the assumption that the audio coming out of the USB is digital, and the digital-analog conversion is being done in the dock itself. Seems like the simplest explanation that the output from the USB port is a digital output. My car stereo is a 2008 Mazda Bose system with a 3.5in AUX input.
Now my question is, where can I get a USB-[single]RCA so I can use the phone as a digital output connection with a decent DAC...

I actually bought a mini amp for a car just to put inbetween the dock out and my aux in......thinking it'd solve the problem.
Sadly while the sound was awesome, there was a ton of static and other noise even with a ground loop isolator in the mix.
If you figure out a way to get good sounding audio out of the dock while in a car......pleaseee post it up!! For now I guess it's back to bluetooth...it's better then having to manually plug in the sound and power each time i get in....
I just use fm transmitter w/ DSM manager n voodoo control plus, Bass is up bumpin.

Eh, the BT gateway is not going to give you the same as hard wired. Nothing will beat hardwired. I don't notice enough difference for it to matter, although my car is all stock. I'm big into home stereo, but never cared to spend the money in my car. I don't spend enough time in there to justify it. But to each his own, just a suggestion. Mine sounds better to me through BT than the dock, but that could be something with my stereo.

This is my main reason for the BT gateway. It defeats the purpose of having a dock, if I have to plug in cable separately. Now I just throw the phone in the dock, slide the connector over, start whatever music app I feel like using and I'm on my way.
Are you using the stock radio in your car? The Epic dock output is not amplified, so if the input on your stereo is made for a amplified output (headphone output for example) then you will have a tinny sound.
Most aftermarket receivers will work with both unamplified outputs and amplified outputs, for example on my Pioneer MVH-P8200BT there is not much difference between with the dock and straight from the headphone output (without Voodoo Sound of course).

yes that's the problem.

I assume that the AUX in for some reason doesn't run through the car's amplifier ??

So you can confirm that the sound is just as good as the headphone out? I have been on the fence about getting a dock, i have an older Pioneer deck & its sound is grate with the headphone jack.
also does any one know of a way to get voodoo with the dock, or is that just imposable?

According to supercurio, at least regarding my transformer, it is all about the headphone jack hardware that is why bt output does not get voodoo controls on og transformer, i assume the same is true with epic..

It definitely runs through the amplifier, however it is probably calibrated for a headphone output and not a Line-Out output. The only time I have experienced the "tinny" sound is if I hook up headphones to the dock.

As I said, on my system there is little difference.. Granted, the speakers I have are not exactly high-end, they are aftermarket and better than most stock speakers.
I have confirmed this by testing the dock on my Monitors. Volume and sound is very close. On my monitors the dock is a bit louder, not quite as clear with a bit too much midbass and over-emphasized highs - slightly compressed sounding. Lower bass levels are nearly identical.
I do not notice this in my car whatsoever. But my monitors cost 5x as much as the component set in my car, so that is expected.
As far as I know there is no way to use Voodoo Sound with the dock.
I have the CleanGB ROM installed and use the stock car dock. I get perfect audio output to my car stereo using a 3.5mm mic -to- RCA cord.

Stock Epic / stock stereo
I have (almost) completely stock Epic (only non-rooted GPS_Fix.zip) and stock stereo (Lexus ES350) and Samsung Car Dock. I use the Dock Sound Redirect app from the Market to direct sound from E4G thru USB to dock stereo phone jack to Aux in on car stereo. The overall sound is fine; not the same as a high-end home stereo but as good as the car stereo & CD. The volume is slightly lower due to non-amped input. Nav audio also runs through this route. Perhaps the issue is stock vs CM7? The Sammy Car Dock works fine for me with the Sound Redirect app.

J3ff, I feel your pain. I bought the Epic shortly after it came out, and the car dock about a year ago. There's a world of difference in audio quality between the headphone jack and the USB audio output that the dock uses. I've used the dock on Froyo, Gingerbread, stock and custom ROM's, it doesn't matter. Haven't tried Shadow kernel on CM7 yet.
The problem becomes even more apparent if you're using something like Voodoo Sound, which affects the headphone jack output but not the USB audio output. I believe Voodoo (and probably DSP Manager, etc., but I can't confirm that) affect the audio on the DAC on the headphone jack, but since the process of converting audio for the USB output is different (and it's not using the Wolfson WM8994 as far as I know)...
I ended up reverting to a $5 cheapo generic car dock that attaches to an A/C vent so I could still use the headphone jack for audio output

Just flip the dock upside down.

Thumping sound on headphones

I've noticed a loud thumping sound, same loudness as whatever I'm listening to, while using headphones or plugged into the auxiliary input in my car. It happens whenever I do an action like exit or open an app, or when an audio track ends or starts, example being whenever tracks change in Play Music.
Verizon is sending me a replacement phone, so I'll post if I notice it on the next one or not.
Same on T-Mobile version
It happens on my car aux input. Every time I hit play on a song, there is an audible thump before the music starts
This happens to me as well on my VZW G2. Mainly when its plugged into my car and I change tracks.
It happens to me too

I know its not the car's aux input (via headphone jack) as 2 other phones work fine in the same car.
No clue. The two and only things relating to audio I have modded is increasing gain to 65 and removing the headphone notification. Doubt the latter makes a dif. I have used the tone 730 bts, 4 dif sets of plug headphones (one had separate jack for Mic), two dif USB wires for aux through mpt on Pioneer head unit, and one headphone to headphone aux input on Pioneer unit. I get crisp clean audio, no thump.
I've noticed mine does it in the car but when I connect to a Bluetooth speaker or use headphones it doesn't

ok, I've narrowed it down to only happening to me on Google Play Music on the current phone. I have someone from google working on the issue with me now. Did try a different aux/headphone cable, no difference.

Discovered another app that does it, Stitcher. Same behavior, whenever a podcast is started/stopped. Google punted the issue saying its hardware. I opened a case with LG support and they said they are already aware of the problem and are working on a solution to be included in a future update.
Mine does it even on bluetooth. Tested with a jbl charge and a jambox mini.
