What's inside this baby! - Galaxy S II General

Now that we have a early dump of the ROM we can see what internals this baby will be housing.
DAC: Samsung have parted with Wolfson and now incorporate a Yamaha DAC as seen below:

Sorry for being a total noob in this matter (and android in general as the SGSII will be my 1st android phone lol ) but I have to ask:
Is this good news?

The Wolfson with the voodoo produced one of the best audio quality on a mobile phone, this Yamaha DAC is not really well known yet, the 2 at the end of it may suggest it's a version 2? Seems to be housing a YMU818B DAC, we won't know until someone actually compares both phones!

so I dont get it.. it has bluetooth 4? o-o

WOW! This is like... a worst case scenario!
I BOUGHT and LOVED the SGS because of it's outstanding audio quality (which even became better with supercurio's work). Now I'm really thinking about not getting the SGS II. Thanks a lot Samsung, that's your own mistake...

Guess I'll be dusting off my cowon s9 again when I get the gs2.

It's possible that the pre-retail hardware is different than retail. We just have to wait and see. We need a ROM dump of the 2.3.3 version.

Okay. Was to be expected as the prototype didn't have wolfson.
Then again that doesn't mean Yamaha is crap as it could be a newer version. We need somebody to look into that matter who has the retail phone (to point out if it's equal or better to the prototype yamaha dac.
I still have hope that the retail version has a "tweaked" version as the prototype got critised by curio.
EDIT: Plus, reviewers said the sound of the phone was awesome, that doesn't quite match up with what we just heard :/

Whaaaa... so he consider not to buy a phone because it has a yamaha audio chip instead of a Wolf-whatever one ? c'mon lets be serious I really don't care bout what voodoo thing he will bring, I've already disabled it on my gs because I Hate the sound that it produces

I think everyone has its own preference about phone they're going to buy. Probably to them sound quality is one of the most important, well not for me anyway.
But it's interesting following the discussion here

I mean I agree, I always disabled voodoo sound on my captivate, but what sounds good to me probably sounds awful to other people.

Well that's you maybe. And maybe I don't care about the GPS thing. If it takes 2 secsonds, 30 secs or 2 minutes - I dont' care. My SGS is my MP3 player, not my navigator.
So don't tell us things like voodoo is useless or that it produces bad sound. For audio geeks, the SGS was a dream and supercurio even made it better. So yes, I perfectly understand why he is hesitating now as I am as well.

Help installing Voodoo Control Plus

I really want to install Voodoo Control Plus however I'm a total tech novice and haven't got a clue on how to get it to install and work. Anyone kind enough out there to give me the quickest most simplest (and least dangerous) method of being able to setup the app? My main emphasis is going to be on changing as little as possible. I would love to play around with root access and custom roms and stuff but in my own time and once I've became a bit more experienced with android phones and the community.

hardware limitations. supercurio was essentially able to develop voodoo for wolfson dac based devices as the defects back then were software based and were solved by rewriting some of the buggy code.
The yamaha dac used in SGSII meanwhile has some critical hardware flaws that can only be resolved at the production/design level by the manufacturer. As an independent user just like the rest of us, all supercurio can do now is to feedback his findings to yamaha and hope they resolve the issues in future batches of their dac...
That's basically what I gather from supercurio's twitter posts and his reasoning for not pursing voodoo sound on the SGSII.
I wonder though if the color banding seen on the sgs2 is also caused by the sharpness filters mentioned in the voodoo project.
I sold the S2 and went back to the original Galaxy S with voodoo sound mod.
The difference is day and night ...... and the Galaxy S has far far more volume for driving headphones.
I did prefer the S2 screen and camera, but the sound was just truly horrible. With no prospect of a sound fix on the Yamaha card and no word of a volume boost there was no point going on with the S2.
Sadly, if playing music is a priority then the S2 is not for you!

Volume+ boosts the volume fine on my SGS2....
All volume+ does is rack up all the frequencies on the system EQ and it sounds terrible.
Enable Volume+ then look at the curve it sets with the equalizer app. It's not a volume boost as such rather an EQ boost that makes the distortion worse!
Keith
FWIW I don't find the sound that bad on the SGS2 using Classic Equaliser and Normal sound effect... yes it could be a touch louder, but it compared OK with my Sony NWZ-S639 walkman which was highly regarded for its sound quality a couple of years back, I also had an iphone 4 beforehand.
I'm not saying the SGS2 is perfect for audio playback, far from it, but it is COMPLETELY blown out of proportion on here.
Bit of a noob question here but I'm finding it difficult to find clear info on this.
I've just switched from an iPhone 3G to the SGS2 and the volume on the SGS2 (with every band maxed in the equaliser) is only about 2/3 of what my iPhone maxed was outputting (nothing too scientific - I just listened to the same track on my SGS2 as my iPhone with the SGS2 headphones).
From reading this I get the impression that this is the highest volume I'll ever be able to get from the SGS2 because the audio hardware is kinda lousy - is that right? Or is there any other way I can boost the output?
Sometimes i think I'm crazy; I'm using the S2 with the lowest possible volume output with my custom molded earphones (almost no resistance) but even with high resistance headphones (eg. a 300ohm beyer dynamic) it's still more then loud enough for me. What bothers me though it that the dac chip is just crap soundwise, low on stereo seperation and an enormous boost for midrange tones; as if the headphone output is meant to be used as a headset for crips and loud talks.
My desire hd had a better sound output (which was still louzy).
can any one shed some light on service mode *#197328640# i read somewhere online but could not find any difference....
[5]audio > [3]WB > ....headset...
This depends on the headphones I can't go Anywhere near half on the sgs its just too loud. If your using high resistance headphones get an amp ?

SOUND QUALITY: SGS II vs SGS

I read somewhere that the sound quality (for music) of the sgs II is inferior than the sgs's..
I also read that, it isnt even tweakeble as on the sgs (for instance voodoo sound)
Can anybody confirm this ?
With some technical background?
«»
Most - myself included - feel that the SGS was better.
The SGS2 isn't the disaster some would claim, but for me it's inferior (subjective), but adequate. I use Poweramp.
Supercurio is the man on this subject, and he's done objective analysis:
http://forum.xda-developers.com/showthread.php?t=1053978
Obviously, YMMV - source, headphones etc.
Edit - should stress I used Voodo sound almost immediately on my SGS - so can't really give an opinion on stock SQ on SGS. Sorry for not being clear
For me its not worse than SGS1 and i am happy to use it as my main MP3 player ..

Thanks everybody,
Still reading some articles and threads, but what the comparison concerns I can summarize it as in this quote:
Ask Supercurio for information, and read this thread at XDA http://forum.xda-developers.com/show and have a tastethread.php?t=1053978 . Most everyone who isn’t an audiophile will be happy enough with the SGSII audio quality, and those same readers will likely find my take on the sound quality is pitched at the right level. So…
AUDIO QUALITY
I should point out here that the SGSII does not use the fantastic Wolfson DAC that is found in its forebear, Samsung instead went with a Yamaha one this time. Is it as good as the Galaxy S with Voodoo Sound? Heck no. But then in the mobile phone world nothing is. I do think it’ll be fine for most people, even if their intent is to use the SGSII as their main music player.

Sound is important for me I do believe the Wolson DAC makes a difference
Going to be sure next week: I'll take some headsets to the a store nearby and test the sound of the sgs II . Need to be sure, before going selling my sgs....
Suddenly, I am not in a hurry anymore, to sell it....

P.s.- Lol...just got an short answer from Supercurio here: http://forum.xda-developers.com/showpost.php?p=14873079&postcount=2478
.
I think for me, SGS stock is same if not slightly worse than SGS II. Voodoo SGS is better than SGS II
Thanks for the kind words about my review
I think the OP has found their answer, and I think taking some headsets along and trying one out is totally the right thing to do for anyone who really does need good audio from their phone (and can tell the difference).

Samsung Focus Audio Quality Improvement

as we should all know by now, through the diagnostics menu on a Samsung focus, one can manipulate and change the volumes of the phone, when the headphones are plugged in or not. The next thing i think we should work towards is tuning the frequencies at which audio is played back. Windows Phone 7 did not give us any equalizers but I think it might be possible to tweak the sound via this diagnostics menu regardless.
Here are the Sound Tuning effects with HEADPHONES attached;
Sound Tuning = 1 1C 74 4 23 9D 95 12
System Gain Attenuation = 5 145 0
Class Gain Attenuation = 5 0 36
Device Gain = 5 400 -1100
audience.cfg = Off
Has anyone tried messing around with the "Sound Tuning" settings to try and achieve more bass & treble? I will start manipulating some variables and record the outcomes on this thread. If anyone else is interested in doing so, please do so!
can this be used to make the phone louder when a headphone cable is attached?
my text to speech, navigation, and call volume is so much lower than the music volume, which makes it kind of a pain when i use my focus in the car with the aux in on my stereo.. :\

I found that apparently the NoDo update greatly improved the audio quality of my Rev. 1.3 Focus. I now consider it on par with the Infuse I had, which was quite excellent sounding. I use high-end IEMs and can confirm the SQ is excellent on the Focus.
Sadly, I can't get the Mango update. Though it was released on Sep. 27, 2011 for AT&T, which I am on, mine is left out in the cold. MS lied and didn't put out the update for all phones...probably a selected few people. So I can't say whether the SQ would improve from NoDo or degrade.

Sure you can get it, there is no physical reason why you can't, you just have to wait. You weren't left out in the cold at all, you merely have to wait. MS didn't lie, they said the updates were going out in batches. You need to grow up a bit and stop whining, you act like MS has singled you out to punish you. I remember you now from early this year in which you drove people crazy with your negativity. Back again are we.

wtfook
people, this was supposed to be thread about sound quality! I do agree that sound quality improved after NoDo, but i cannot confirm any noticeable difference with Mango.
Regardless, i really f'd up my Mango Focus when messing around with the Sound Tuning settings, and basically had to do a hard reset to return the phone's functionality. So if any of you brave souls are tinkering with the Sound Tuning Settings, just dont push the values to their maximums like i did, for some reason it has an adverse and negative impact on the operating system.
Therefore, as long as MS doesnt introduce a dedicated and good equalizer that doesnt cause distoration (cough Apple products cough cough), then i guess im just stuck with these plain stock settings.
As per the Sound Tuning settings, it seems like we can only change the device gain and class gain. I am not satisfied with this, but i am patient. If samsung really wants to beat every other smartphone in the market, they need to start taking audio quality more seriously (its good, but not great), espesically with SE's Xperia lineup and now the HTC Sensation XE backed by Beats by Dre technology (as subjective as that may sound, it actually does improve sound quality).

How to get Google to take note of the USB DAC problem in ICS

Hi everyone,
Thought I would post about an Android issue that is bugging me - the fact that despite USB Host functionality being present in ICS, USB DACs (digital audio converters, external sound cards if you will) do not work with our devices .
If they did work then we could use relatively cheap USB DACs with our Android phones and enjoy great music sound quality, no matter which cheap DAC/DSP the manufacturer has seen fit to include. Ever since I sold my Galaxy S, which has an excellent Wolfson DAC and can produce awesome sound quality with Voodoo Sound, the sound quality of my subsequent devices has rankled. Now with ICS this is a simple software fix, which makes it all the more irritating (someone has managed to add support for these in a Nook Colour kernel that works with CM9). To be honest I'm seriously considering buying an iPhone for the first time ever because they have this functionality out of the box.
Fortunately there is something we can do about this besides making ineffectual unhappy noises and waiting for customs ROMs etc to fix this - vote the issue up here: http://code.google.com/p/android/is...rs&colspec=ID Type Status Owner Summary Stars
To vote just star the issue.
This issue needs ~1150 votes to enter the top ten, which doesn't seem a big ask given the hundreds of millions of Android users out there... (it's got 66 votes so far today and risen 16 places up the issues ladder).
Please star this and share this out to your social networks - help save me from having to continue think about getting an iPhone!
I also posted about this issue at my blog, if you were planning to share it out over your social networks that might be a better thing to link to:
http://www.androidnz.net/2012/02/android-usb-host-for-audio-devices-fail.html

+1!
I would also really like to see this implemented. Shouldn't be too difficult for them, methinks? The nook already seems to be able to do 24/96 with a USB DAC using a standard USB audio module. Apparently, with the correct ALSA driver we could also do 24/192, even!

No, it's a major ***** for them to implement - ALSA is evil.
Getting audio routing to work properly on a device with fixed hardware is enough of a pain as it is.
Handling audio routing that changes for 3280348230 different peripherals would be an utter nightmare for Samsung.
While I agree it would be a cool feature, it's definately something hard. Just look at how hard it was for us to make audio working properly on Ice Cream Sandwich. While some Alsa could work, all devices have their own controls and way of working, so it's really tough to make it work for all at once (which is probably why Google doesn't support it).
First post updated with working link!
In relation to this being difficult, doesn't seem that difficult since it's been done already (the Nook fix was not specific to the E7). Surely doesn't need peripheral-specific support, only needs to be able to send audio out via USB on the host device? The iPhone doesn't specifically support any particular peripherals either...
Anyways, thanks to those who have voted, over 100 extra votes now and climbed 24 places.
Apparently there's a test-build kernel around that would support USB DAC for GB (yes I know we are talking about ICS here)

Interesting! Just been reading there... I would imagine custom ROMs and kernels will support this long before Google
Still, important to try and raise the issue with Google, would rather not wait for x-feature to be ported b ydevs with every new Android device.

I was thinking... some devs could get this thing to work in their custom ROMs on some devices, like Nook color for example. Why should be so hard for Google to implement this? I have a tablet, and could make ALSA recognize my DAC with appropriate libraries, but route audio to the DAC is imposible, tried to mess asound.state, alsa.conf, etc...
Seems to be something hard, but there are devs who could get it working.
If the problem is that each DAC has its own protocol and settings, and that accommodating every powered DAC would be too difficult, then wouldn't the next step be to ask a few specific companies to design and build Android DACs around a fixed set of values, commands and so forth, and to introduce them on a very small scale at first -- so that, while not every DAC worked with Android, a few specific ones did? That's what a certain fruit company did with the Wadia 170i and the Cipher Labs AlgoRhythm Solo.

I think the guys from Wadia/BA went to the Android SD requesting Google to help them (for the Droid & Captivate ) but they got a naked bird instead..remember that Google only recently have launched the music store...
I think audio hardware is one of those non standard things across android platforms and getting the audio -usb dac protocol to work across all devices would prove difficult if not impossible for stock android.
But yes, it's a feature id definitely want to see implemented. But I think the devs might have to take on this one.

This has already been accomplished on the Nook. It's not difficult.

If it's not hard, please do us all a favor and implement it yourself.

So out of curiosity, if we did indeed have ALSA working with a USB DAC, would that bring the audio latency down to near realtime speeds?
If there's one are that iOS is superior to Android it's with low latency audio performance, and that's why you don't really see any softsynths or guitar processing apps for Android, sadly.

Good question.
Would be another benefit. Even if I care only for external DAC's with superior sound quality, I'm sure that there are people waiting for this

You galaxy sII people are lucky, cyanogenmod supports audio out via usb. Still no real love for the galaxy nexus

Does anyone have or tried the new joying JY-UM135N2D

Has anyone used one in person yet? Does it sound any better or worse?
I have bought it, and my opinion is that it sounds very good. But I'm not an audiophile and it's my first Joying unit so can't compare. I did have to turn off SRS and a "LOUD" option in the menus or else the bass was too booming.
But for me, it has ample quality & power for my needs.

Do you you happen to have some pictures with the unit motherboard?
Thank you

Actually, yes I did take a picture. Here you go:

I will need to take the front off to replace the digitizer when I get it from Joying (Part of the touchscreen does not respond to touches). So if you need a better closeup of something, just say so.

Same internals.

seeing a simple 2DIN (with standard screen) internals my intuition was correct and I think (of course I can't be 100% sure unless I will buy and motherboard and swap it myself) they lied to me because it's almost identical with the board that I am having in my unit.... so upgrading just the motherboard looks promising... but I guess time will tell.
It's the current sophia Joying with a Class-D amplifier and we can make a reasonable assumption is probably to reduce manufacturing cost. Class-D isnt new nor does it mean "audiophile". Considering all parts of the audio chain, such as preamp, DAC etc, even installing a class A amp wouldnt improve the overall quality. Dont buy into the marketing spin
Yes, but you do get more features with the new board and less heat. There are some advantages.

Compared with the first generation is better..... at least they FINALLY offer a decent EQ solution and given the fact that are the only ones out there doing this I applaud them.... The others still drag the same old amp chip from generation to generation like they drag the same crappy bluetooth inplementation.... Yes the quality might not be for everyone but you need to consider that they sell them for $300.....
If you want high audio quality you need to empty the wallet for at least 700$ up to 2000$

Less heat generated by the amp because unfortunately the SoM still does not have a proper cooling solution and even if this generation (FYT6021) is of a tiny bit better designed it's still not good enough.

Generation 2? This is the same hardware with a class D amp replacing the class AB amp. Users are paying more for a unit that costs less to produce but with software that apparently sounds better. Do you realise how your comments sounds?
Let's be clear - there is nothing wrong with the stmicro class AB amp, Joyous replace it with a class D amp and save on manufacturing cost. The software could be applied to any sofia - the codec / DAC is the same.
To say "same old amp chip" is nonsense. Thanks for your opinion - also did you also realise the codec hardware is actually 3 band parameteric.
The youtube videos are pure comedy.

First of all please take a deep breath and relax, we are sharing ideas here, opinions, don't get angry or upset for nothing Also please don't use phrases like this " Do you realise how your comments sounds?" with me.... is not like I tried to convince you that our sun is flat....
No, what I meant was that first generation unit had the 5009 SoM... the second generation was quietly introduced with a slightly improved 6021 SoM and very other small modification like removing the video out ports for instance..... and now they decided to take the 6021 and work the magic with the amp. Maybe "generation" is now well put here because the changes between the models were very small but I am sure everyone gets the idea.
To be honest I did not dive into the amp details on the old units versus the new but OVERALL my impression is that the AMP/DAC solution presented in the Chinese units in the past 3 years is about the same and the sound quality is modest.
The problem is that in my car I want to be able to tune the music to my liking and all of the Chinese units have very, very poor EQ that in no way can help me achieve my goals.... The fact that the amp is class AB means nothing to me (or for most of the people that buy these units) if the sound is not good... and EVERY single Chinese unit that I've seen lack in the bass department BIG TIME no matter the EQ settings or if they use an class AB amp. The only thing that made things better was Viper4Android.
Now if they decide to put an D amplifier, so be it, as long as it sounds better and it's more customisable than the AB amplifier was that is fine by me.
You need to remember that very few people struggle to root their units to be able to install Viper4Android for better sound so choosing between an class AB amp with poor 3 band EQ and an class D amp with software EQ with lots of bands that makes the sound a lot better ... guess what everyone will prefer?

I am entitled to have my opinions. You might like them or not, that depends but try not be be ironic or sarcastic.... it's not helping me one bit.
If you want to help me understand explain to me your opinion, your side of things, how do you see things and do it in a friendly manner, educate me and everyone on the matter at hand. I am sure that me and everyone will appreciate it.
Thank you
