What is the Audio IC inside MPM1? - Asus ZenFone Max Pro M1 Questions & Answers

I think my audio IC is broken, the right channel (through 3.5mm jack) only outputing (white/pink) noise..
The speaker(buzzer) seems ok,, bluetooth also sounds clean.
But only R channel audio from 3.5mm jack is problematic.
It happen after I accidentaly connect the rca input to the power amp output...
Do you guys know the number? Its a NXP chip right?
I can't find it online.
Or, is there any compatible IC series available?
Should I try change the daughterboard first?
Thx in advance.

Connecting phone to a car stereo

Hi all
I have a MDA compact which I wish to connect to my car stereo as a handsfree unit. I have an auxiliary input for my stereo.
Is it possible just to purchase a 2.5 to 3.5mm lead for this? I have a gut feeling the mic won't work - please help? Is it possible to buy such a lead with a built in mic?
Thanks
Carl
Hi, I used to have a XDAII which I connected to the auxillary port on my car stereo, just like you suggest. It worked perfectly. When using the phone, the caller's voice woudl come out of the car speakers and the mic was powerful enough to pick up my voice even though the unit was mounted on my windscreen.
Unfortuntely, both the Wizard and the Exec automatically disable the mic when you plug into the headphone socket. Not sure about the MDA comact. Sorry couldn't offer more advice on your particular device, but I hope my experiences help.

I do have the same setup. I can confirm U the mic still work after U plug in the adapter but I normally use a BT headset when I am in the car.
OK, so I assume that if I purchase a 2.5mm to 3.5mm lead, the mic should work?

Yes. 8)
OK - did some work on this.
I decided to cut the earplugs off of the supplied headset, and attach a 3.5mm socket.
I now have a custom XDA mini lead
All works, however volume from car stereo speakers is extremely low. Any ideas? (Yes, I have checked car volume, phone volume and headphone volume!)
Cheers
Carl

Hi Jackleung, my mic is being diabled, and i am beginning to think that I may not have the right connector. I have a standard 3.5mm connecting the exec. Can you let me know how you have wired your device with the type of connector? You may be able to solve a longstanding problem of mine.
Thanks in advance.
I found my mic was cancelled with the Mini, hence the custom cable.
hope this helps!

I think my adapter is just a standard 2.5mm to 3.5mm converter. I tried 2 different adapter (one from Radio shack and the other one from ebay: http://cgi.ebay.com/USB-CABLE-headp...ryZ15040QQssPageNameZWD1VQQrdZ1QQcmdZViewItem)
Both are working for me (I will try again today and confirm U tomorrow), therefore I think yr problem is in the exec hardware itself.
To Carl,
Yr setup will not work since yr supplied headset adapter has at least 4 connection on the plug compare to 3 on the standard one. The extra connection is for the mic. If U cut the wire like this:
<---- X --- mic+volumn control ------ ear plugs
Then U can no longer use the mic w/ the custom wire. But if U:
<------- mic+volumn control -- X ---- ear plugs
then the mic on yr mic+volumn control will pick up the voice
hi jackleung
Thanks for the reply - the lead was cut after the mic but before the earphones.
This was because a standard lead with a 2.5 / 3.5mm adaptor didnt work.
My only issue now is the low volume!
Cheers
Carl
I tried it on my Imate Jam again. My mic on the Jam still works (eg: Voice Command via Cyberon Voice Dial. So do phone conversation) even I use my 2.5mm/3.5mm adapter to connection it to my car stereo.
Hi,
I did the same for me and a friend of mine with a Univer..er - Jasjar and connected this to an FM transmitter - We have excellent sound quality, volume and the you can still answer calls by pressing the Mic Button

check connections?
I have done exactly what you did, put a 3.5mm socket on the end of the included handsfree cable.. volume is fine, and i regularly connect it to the aux in the car, and multiple sets of headphone/speakers...
The best suggestion to your volume problem is to try again.. i know i had issue with the stereo channels getting screwed up (and even combined at one point) and it was just trial and error getting the connections clean..
You have to ensure that both the shaft and tip connectors on the socket are grounded to the shared ground on the circuit board.. otherwise the audio will probably be less than perfect.. check for dodgy soldering/connection.. coz i can assure you that your theory does work!

There is another topic on this here.
The person from there uses:
http://www.expansys-usa.com/product.asp?code=PPCPADPT02
which has two 3.5mm plugs.
Description: It has a 2.5mm plug at one end (this plugs into the PocketPC) and two 3.5mm sockets at the other end (into which you plug your 3.5mm headset or headphones).
My question was: could I put a standard 3.5 car kit mic into this 3.5 headset jack (the one with the mic)? Would the mic work if I plug it into a headset jack?
I assume the other one (headphones = stereo only) I will plug it directly into my car auxiliary via a 3.5mm to RCA cable, right?

Is the 2.5mm headset jack on WIZARD video compatible?

I have this cable that plugs into a 2.5mm jack and on the other end are RCA connectors for a TV. Does anyone know if the headset jack on the bottom of the WIZARD has video compatibility or if it does, do I need some program to route the video to the TV?
Any help would be appreciated.
No, I'm pretty sure that the jack is audio out/mic in only. Sorry.

HTC 8525 in car?

Alright, may be a little off subject, but I need some advice. I am trying to figure out a way to hook up my htc 8525 to my cd player in my car. Unfortunately, my cd player does have a AUX hookup, so I am not able to just buy the Mini USB to 3.5 mm cable and hard wire into my CD player through the AUX input. Any ideas on another way to do this? The car does not have blue tooth integrated neither.
Thanks in advance!

No AUX input.. no bluetooth... kinda hard, but not impossible. Depending on the brand of your car deck, you might be able to buy an auxiliary input adapter. I know for sure that Pioneers do that. You can buy an "ipbus adapter" that plugs into the back of it where the CD changer would and you can route the audio from your phone that way. I know Alpines and Sonys also have this ability.
your best best and pretty inexpensive ...is to use a fm transmitter alongs with your Mini USB to 3.5 mm cable this is how I do it with hy 8125 and plan to do with my 8525 when I get my Mini USB to 3.5 mm cable

Interesting.. I have a Pioneer deck, so I may be able to do it this way! Will have to check the deck after work to make sure that it has that connector on it. Thanks!

Yeah, I thought of this option, just hate the output quality with an FM Transmitter. Thanks!
Yeah the FM quality blows usually. Go to your local car audio shop to get one of those adapter. They're about 20 bucks. I know Best Buy has them, that's where I bought mine.
Do a search for PIE Electronics Auxilliary adapter... if your head unit has CD-Changer control ( like my Honda Pilot) then you can get a PIE adapter which basically gives you an aux input. The sound quality is FAR superior to the FM modulated stuff. The adapter takes a dual-rca style input - so you'd need the 3.5 adapter into dual rca into the PIE. Works perfectly for me with my Sirius - and if I want to listen to my 8525 I just unplug the 3.5 from my sirius and plug it into my phone
Side note - if you get a PIE adapter - do *NOT* connect the ground. I know that sounds odd but I got wicked alternator noise with the ground connected to a good ground, go ZERO noise with it disconnected entirely.
i just modded the stock headset, chopped off the headphone wires and spliced in a 1/8" male audio connector and RCA outputs, i have aftermarket radios in my rides so i have RCA inputs..

Yeah, I checked my CD player yesterday, it does not have the CD changer plug. How did you do this through the RCA plugs I know my head unit has RCA plugs because I currently have my AMP hooked up to the RCA plugs. I just don't see how RCA can be used to take in sound and play it through the speakers, I thought RCA was for output. Maybe I'm wrong?
If you have that going to an amp, the RCA's you're using are "pre-amp outputs"- operative word being outputs... Most radios do not have auxilliary RCA inputs... I have a kenwood KDC-mp528 that does...
Look into _WIRED_ FM modulators
The same concept as the wireless FM deals, but without the interference and associated sound quality issues.
They basically plug in between the antenna and the head unit. when turned on, they completely replace the signal on the selected frequency so even a strong radio signal will not interfere.
The concept is well-illustrated here:
http://www.crutchfieldadvisor.com/ISEO-rgbtcspd/learningcenter/car/peripherals_installation_guide.html?page=3
Prices vary by features, but they're normally cheaper than the wireless equivalents. Look for examples here:
http://www.etronics.com/c-2435-modulators.aspx
Hope it helps!
you could just hook the 8525 up w/ the RCAs to the AMP and have a way of switching between the headunit and 8525...
just an idea

Car stereo auxiliary jack silent?

I just got a new car that has an auxiliary jack that says I can play my music from MP3/Ipod players. I bought myself a 3.5 mm cord, plugged it into the HD and the Auxiliary port in the car stereo, but there's no sound.
Is there something else I need to do in order to hook my Blackstone up to my car stereo's Auxiliary jack? I figured the 3.5 mm Auxiliary port would just hook up to the HD's headphone jack as if the stereo would act as headphones. Am I wrong?
With mine, I just plugged the 3.5mm jack into the HD and every sound even phone calls automatically came through the cars speakers.
Try plugging another device with a 3.5mm jack into the car, if there is still no sound the theirs either a setting on the head unit or cable may be faulty.
Here is the cable I used, connected directly to the back of the head unit using RCA connectors.
http://catalog.belkin.com/IWCatProductPage.process?Product_Id=172348
Hmm, does sound (sorry) like a cable problem. I have plugged the HD into external speakers via the 3.5 socket with no problems.
What you are aiming for should work but the cable needs to be right.
You probably have to go to the option on your car stereo. It's just like changing from the fm receiver to the cd player on your car stereo (except you have to go to aux-in).
Look in the car stereo manual how to activate the aux-in option.
If Headsets work fine on your HD this should work as well.
Then it's not a problem with you phone.
Thanks for the replies, everyone. I did switch it to the "Aux" function as opposed to Radio/Satellite/CD/Etc., so I'll see if my son's iPod Touch works or maybe there's something else I have to do with the stereo in the user manual. Otherwise I'll assume the cable is faulty. Hope my wife didn't throw out the packaging just yet! It was just a cheap $7 retractable one I got from Target. Next option is a 3 foot $15 one.
Also, make sure you connected the cable to the aux-in on the stereo and not the aux-out. This isn't always indicated in a clear way (I'm just thinking what it could be).

Yep, thanks for the input. Luckily it's pretty idiot-proof. It's the manufacturer installed Bose stereo system in a 2009 Nissan Rogue. There's only one input on the front face of the stereo panel labeled "Aux In". And you press a button labeled "AUX" to use it as far as I know. Pretty handy!
i have the same problem with my Alpine stereo,has an AUX Input,Even when i enable aux on the head unit still no sound.Taken it to my local car audio garage and theyre baffled!
Later said to me it could be a faulty HU
Ah, well I am used to after market stereo's with the connections on the back (rca connection).
Sorry that I'm not able to help. Well as long as you get sound through headsets and such it is not a problem with the HD, but I guess you figured that out.
Sadly those RCA's are usually outputs for an amp :'(
I'll test my son's iPod Touch today with the cord and see if his works. If his doesn't work also then I'll try a different 3.5 mm to 3.5 mm cord. If THAT doesn't work then I'll have to assume the stereo is malfunctioning.
Another thing that crossed my mind is what if the headphone jack on the HD doesn't produce enough juice to feed into the stereo. Would that be possible? Although it sounds like others are able to get theirs to work, so I'm assuming the HD puts out enough.
Thanks again for the quick input, everybody!
when you plug the lead into the touchHD, you do get the liitle headfones show up on the topbar of the screen?
you havent muted the media player somehow?
you have removed the 100dB eurolimit on the HD output yes?
vol on the HD is around the 80% on both media player and general system sound?
AUX is actually enabled on the headunit in the car? on my factory fitted headunit, the aux button is switchable between the aux line in and an external cd player... if you have the manual for the headunit, have a look to see if there is this option
the headfone jack on the HD pushes out plenty of power, especially if the 100dB limit is removed (hd tweak or advance config... dont forget to disable audio booster and the EQ as that will really mess up the sound)
