Distorted Sound on 2Gb MP4 Player
 

Hi all, I need help please!

I have a Soundwave 2GB MP4 player which i have since found out is actually a MultiUnit MPF334.

The problem i have is that whenever i listen to music it sounds "wobbly" or as though you are underwater.

I have tried deleting the music and re-uploading it. I have tried reformatting to both FAT & FAT32. I have also tried 7 different headsets with no difference to quality of sound.

My son has exactly the same make and model and all of the music off mine plays perfectly on his - all headsets work as well.

I found the MultiTech website and visited it to see if there was a downloads section (there was but empty) or a trouble shooting guide (there wasn't). In fact the website is in my opinion a waste of bandwidth!

I go on holiday in a couple of days and would like to use my MP4. If i can't get it fixed then i'm gonna have to tell my son that HIS MP4 is broken but not to worry he can share mine - but that's not very paternal is it?

Thanks for reading this and any advice you can give.

i had the same problem with my sumvision kpac. heres what i did. took it apart, bent the two front pins inwards to make the earphone socket a tighter fit.

Thanks man,

Tried that - didn't make any difference - must admit though, it was a bitch to take apart!!

Any other suggestions????

Skydoc , does it happen for every single file? What does it sound like when you tune into the FM radio instead?

Re: Distorted Sound on 2Gb MP4 Player
 

It happens with every music track i put on - even the samples downloaded from this site. All the tracks play perfectly well on my sons MP4.

As far as FM goes...even though i have it tuned to exactly the same station as my sons, i can hear the radio perfectly on his but not a sound on mine.

do you think it might be a F/W issue?

If the player is new it might be a good idea to try and get a replacement
If you try and update the firmware it may kill the player, also It could be a hardware problem not a firmware problem

It's past it's warranty - my wife got it for me as a present and i've been abroad for quite a while so never actually did more than look at it and say thank you.

It's only the past couple of days that i actually decided to get it out of the box.

Never mind - i'll just have to cook dinner tonight and sweet talk her into buying me a new one!

If its unusable it might be worth trying to flash another firmware there are lots on this site, the hard part is finding the right one.

Need to start by looking at what version firmware it has in now and trying to find the closest match.

Ver:00.26.1845

Is that what you mean? That's what is says on the MP4.

On the disc it came with it has the following file:

0700C_1.79new_Soundwave_En_MLC.rfw

Do i need to use this file and how do "flash Firmware"?

I'm a complete noob at MP4's and stuff.

Re: Distorted Sound on 2Gb MP4 Player
 

Yes you've got a Rockchip player.
The file ending in .rfw is the firmware.

You have to install the ConsumerUpdate software from the cd on your computer.

Then load the firmware into ConsumerUpdate.

Go into update mode on your player via the settings menu and connect the usb cable,

Click the update button on ConsumerUpdate to flash the firmware and wait for it to complete successful before disconnecting the USB

You are lucky to get a firmware on your cd for this type of player.

If this works would you be kind enough to upload it for others to use on this site please?

Hi buddy,

Thanks for the advice...are you ready for the next problem?

All that came on the CD was a pdf version of the manual (utter trash), the firmware file and a folder containing Win98 drivers (who uses win98 these days?).

I've emailed tech support at the multitech website but i don't hold out much hope.

Unless you know of somewhere i can else i can get the consumerupdate software i'm stuck until multitec get back to me - i'll keep you posted. :wink:

We're not beaten yet.
ConsumerUpdate is here:-

Cheers buddy,

I'll get back to you as soon as i've done it!! :lol:

Re: Distorted Sound on 2Gb MP4 Player
 

I try to load the rfw file into it and it gives me the following error:

"This FW is not match this tool!"

I unrared the consumerupdate file, double left clicked on the "consumer firmware writer", then click open and selected the rfw file. Thats when i get the error message.

Am i missing the point or just being a complete mong???

Re: Distorted Sound on 2Gb MP4 Player
 

No it's just there are about 5 different versions of ConsumerUpdate too!
Because you didn't get it on the cd we don't know which one it is.
here is another ConsumerUpdate to try:-

http://www.mympxplayer.org/rockchip-...276-df612.html
That's the version that came with my player, don't use my firmware though,
only use the firmware that came on your disk my firmware will brick your player!
Mine player has a 2" screen yours is different so just use the 2.7.6 version of consumerUpdate

First of all, this isn't a firmware issue at all!!!

It's the headphone jack at fault. Try different headphones, try not plugging the headphones fully, bend the connectors properly and check the soldering, redo it too if necessary.

Whatever you do, don't upgrade the firmware. It won't fix it.

i have a hunch that some component is damaged in it, maybe some capacitors or resistors.

Maybe. Have a careful look at the area surrounding the jack.

Re: Distorted Sound on 2Gb MP4 Player
 

Well it's always worth a try rechecking the soldering first.
I have found however that if you have the wrong firmware loaded on a Rockchip player it can have quite an effect on the hardware too.

From what i can gather this player has never worked correctly so it may even have had the wrong firmware already loaded on it.

Loading the wrong firmware on my player I have had the following happen,
loss of screen, buttons mixed up, distorted sound, lines on screen and corrupted flash memory, another user has reported loss of his loud speaker so it's a risky business.

Still if the player doesn't properly it worth looking at everthing.
hope you can get it back, it's a nice looking player.

Re: Distorted Sound on 2Gb MP4 Player
 

Hi buddy,

Had a very busy day today upgrading to a new computer system at work so i've only just been able to try the other version.

No joy with that one either - same error message.

I'm gonna google it and see if i can find any other versions - multitech haven't responded yet either.

cheers mate. :roll:

Re: Distorted Sound on 2Gb MP4 Player
 

Here's a link with ConsumerUpdate 2.61 in it:-
ConsumerUpdate261

You will notice that there is another firmware in this download don't use that, it's for another player with a smaller screen.
You just need this download to get the ConsumerUpdate program

Only use your firmware thats very important , don't use any other, only the firmware that came on your cd.
The "0700C_1.79new_Soundwave_En_MLC.rfw" file is your firmware.
