Do any of the rezound kernels support Voodoo sound?
And does it cancel out the Beats enhancer?
Thanks in advance.
No. I've asked supercurio if he'd be ok with me building a kernel for the Rezound and he told me that since he doesn't have the phone, he'd prefer me not to. His reasoning was that since he doesn't have the physical device to verify quality operation, he doesn't want his name attached to a potentially flawed implementation.. maybe I'll try again in a little bit and see if he's changed his mind.
BUT, it should be possible, given that he IS working on a ICS compatible Voodoo sound driver for the WM8903 chip I have the beta version for ICS on my tf101 and it has improvements over the Honeycomb version, but the volume control implementation isn't working well yet.

Mostly because supercurio only likes Samsung devices, and won't allow Voodoo Sound on devices he doesn't own cause he cant offer support for them. I have Voodoo Sound on both of my Asus Transformers, and that has the same Wolfson WM8903 chip handling audio that the Rezound has. With the ICS kernel source code for the Rezound and supercurios source for the driver, it wouldn't be impossible to compile a kernel module that could be loaded on the Rezound to get Voodoo Sound. Or you could build it right into the kernel and forget the module... either way, it would work if supercurio would be willing to let me or anyone else build it for the Rezound, but he isn't currently willing to do that right now.

What then does this mean for development of a "Voodoo-like" audio implementation for the Rezound? I'm guessing the different DAC came as a surprise (and somewhat of a disappointment). However, all the talk of "this DAC is better and more desirable than that DAC" is less constructive than how a particular DAC is implemented. If the best DAC in the world is ham-stringed by poor implementation, then it really doesn't matter much.

How do you find this information...
(I can't find any websites that list the dac)
Anyway, maybe make a voodoo kernel and don't call it voodoo?

Might want to clarify what the acronym stands for. I have no idea what a DAC is.
That's why I don't like to post technical things in the general section. Yet I know I'll get blasted if I post in developement. DAC stands for Digital-Analogue-Converter.

+1 for posting in the correct section though. Developers DO read the general and q&a sections of forums. Just not as often as ppl want them to - so they post in Development to get an answer faster... which is not the right way to go about things.
to put it in layman's term, what audio chip does the Atrix have
I'm curious this too, hoping for an answer

I don't know but it's clearly sub-par, as audited by audio-gd compass and D2000 ... And you can't change it so it kind of irrelevant.
Mayby also someone know is it possible to have direct digital stream from Atrix (bypassing DAC)?

With HDMI out, obviously, but I was also hoping for digital out over usb, like in the car's usb port. I doubt these car controllers know what to do with that connection, unless you can put it into mass storage mode and treat it like a flash drive.

So I traced this out, seems like it has been dead in the water since nVidia bought portalplayer in 2007. Kicking around on the rockbox wiki, I found this android port:
http://www.rockbox.org/wiki/AndroidPort
I read through forums, searched, and looks like an apk for qHD needs to be developed yet. Would like to be wrong. Anyone have info on this?
I hate to dig up an old thread, but this is kinda what I was hoping for. I'm in the process of building a "portable" device that would have a Digital port interface, feeding professional DAC and HiFi headphone amplifier. Never actually tried to connect a phone to a receiver with HDMI connector, but it should work, bypassing phone's DAC and feeding digital PCM signal to external device.
As far as BlueTooth connection goes (for the last poster), then if you are looking for good quality, looks somewhere else. Bluetooth compresses the sound on the fly before sending it to the paired device. For some it might be unnoticable, but to me it is unbearable.
According to http://www.head-fi.org/t/549644/motorola-atrix-sound-quality, it is a Wolfson 8903 L. From what I have read, everything points to the Atrix and the Tegra 2 using a Wolfson DAC. Don't forget that the amp and preamp are just as important to sound quality. Supposedly, ICS may support USB DACs.

Wrong,
Just contacted ('PCWAR'), he said he is unsure, he saw such info on xda forums.
WM8903L is made for Harmony Tegra 2, or tablet Tegra 2.
All Tegra 2 Ventanna uses WM8994 DAC
Yay, we've got the highest end DAC, par with the S3 and Note 2 except bit higher stereo crosstalk.
I'm pretty sure that the Atrix has the Wolfson WM8994 audio chip due to it being Tegra 2. Any chances we could see Voodoo sound (or equivalent) on the Atrix?
We hardly have any devs and we are praying for cm7 and hdmi mirroring. Premium sound can get to the back of the line.
I voided my warranty and your mum.
And im not sure but the audio might be the wm8903. I don't know much about wolfson. Supposedly their pretty good for sound in phones. And they do power management for low powered stuff like phones too.

Wolfson with Voodoo Sound=awesome.
I just don't think we're going to get any dev's that will work on it. We've been abandoned, save for the few that are working on CM7.
we need to get a big bounty started for when the official cyanogenmod team takes over for stuff like this, hdmi mirroring and display chip control.
well the asus transformer already has a semi working port so i dont think it should be to hard to port since they both use a tegra 2 base

I'm willing to donate 50 euros for a really improved sound and things like true line out. SOMEONE ELSE?
Hey guys,
Now that the bootloader can be unlocked, and we can start ROM and kernel development, is the possibility of getting Voodoo Sound (or something like it) feasible?
I have a Voodoo kernel on my Nexus S, and I don't think I could live without it. The fix to the sound, the transformation into a headphone amp, the built-in equalizer-- these are all features I would love to see on my TF201.
I know with the Galaxy S phones and the TF101, the capability of a Voodoo driver was because of the Wolfson audio chip. Is this something that can be replicated with the Prime?
Thanks for your help.
Unfortunately no. The prime uses a realtec audio chip so voodoo sound does not apply. I have also used it on both my last phones and was sad to see the Wolfson DAC not in the prime.
Just use volume+ for all your sound needs. Works great. Thread on it n themes n apps section.
I asked this same question MONTHS ago and it went un-answered. Glad someone picked up on this thread and answered it.
What a damn shame however... because that was a great app. Volume+ just raises the volume... it doesn't even come close to Voodoo unfortunately.
so i have a thunderbolt and a bionic and soon a rezound and of course have a tfp. i was wondering if there will ever be a port for beats to the prime. i have beats on the t-bolt and it is amazing because i have the bluetooth beats. beats only works if the headphones are connected in to jack tho. i would really like beats on here. as a matter a fact i will be trying to port it over. (next two days off and alot of adderall :x)
not that I know anything about this, but I coulda sworn it had something to do with the actual hardware or drivers or something, not something you could literally port over, or I would think most phones would have it..
Entirely software based.

heh, see, I said i didnt know anything.. Franco kernel on my Gnex just got an update enabling high performance sound! seems this is pretty similar to what you are talking bout, so it seems to be a kernel add on of some kind.
Sent from my Transformer Prime TF201 using XDA Premium HD app
yeah just software based. people say other eq are better and what not but just the little icon and knowing you have beats audio is good enough. i played around with equalizers and what not and this is just way better. so stick around ill be getting it
If you cant get it going, Volume+ available from the market does the trick.
It has volume boosting capabilities, along with equalizer settings. One of which is, Beats Audio emulation.
Works for internal speaker, headphones, or bluetooth.

I'd wager that this does nothing for our phone, since it's made for Qualcomm DACs. The Axon 7 only uses the Qualcomm DAC in Standard audio mode on stock MiFavor, and it never uses it on LineageOS and related ROMs.

It might be beneficial for stock users who don't use Super audio mode already. I don't know why someone would use Standard on stock, but this could benefit those people.

In stock, Super audio uses the AKM DAC and amplifier, while Standard uses the Qualcomm DAC. I usually just keep mine on Super all the time.
Super audio mode?
Guys instead of arguing whether or not this is beneficial, just try the mod, it doesn't hurt really.
It's tiring seeing users arguing about something and not actually trying it.

Whatever you say mr developer, I'm so sorry if I doubted your flawless argument.
On a serious note if you don't wanna try it you have every right to do so, but others may be interested, regardless what you think.
You haven't proved somehow this doesn't work, simply stating that it doesn't doesn't mean it doesn't.

Okay.
On other phones, OEMs will use the standard Qualcomm DAC and amplifier. In our Axon 7, we have the AKM AK4490 DAC paired with the AKM AK4961 DSP and amplifier.
If you are using LineageOS, the AKM DAC and DSP/amplifier are enabled all the time and the standard Qualcomm DAC is not used at all. This is because of a recent patch in Lineage. Let's review what this mod does:
"enables Qualcomm's high_performancce_mode on your in-built WCD9xxx DAC, this switches headphones class amplifier from Class G to Class A/B"
and
"sets your ALSA sound PCM rate converter to its maximum quality (samplerate_best) and your syetm-wide resampler quality to '4' (Maximum quality value). "
That's great, but the Qualcomm DAC is not used in Lineage. So, this will have no effect.
What about stock MiFavor? Using stock, you can switch between the Qualcomm DAC (Standard mode) and the AKM DAC (Super mode). I can assure you that even with this mod applied, Super mode will be better than Standard mode simply because of the better hardware being used. No amount of software tweaking can compensate for an inferior Qualcomm DAC.
If you set audio to Standard mode and use this mod, the only thing changing from a Class G to a Class AB amplifier will do is remove one voltage supply. It will not impact the audio in any way. If you set audio to Super mode, the AK4961 amplifier is a class G amplifier and is not changed by this mod. Even if there was a mod to change the AK4961 to a Class AB amplifier, it would not change the audio at all. So, in stock MiFavor it will have an effect, however that effect is made useless since we can switch to Super mode and have a better audio experience without using this mod.
This is not just what I think, these are the facts about our Axon 7.

That's a more well-constructed answer, I'm glad you know how to talk after all.
When I was on mifavor some time ago and used the mod, normal mode sounded better on my headphones than super mode ever did until that day.
Maybe it's the headphones to blame for that?1
In any case I definitely heard a difference.
Anything that can improve our phone is beneficial for it, you're free to use it or not of course.

It's very possible it did sound better because of the headphones instead of the phone's audio hardware. The AKM audio hardware is better suited to higher impedance, high-end headphones. If the headphones you were using weren't high-end, Standard mode really could have sounded better.

Yup! When using my IEMs which are also 16 ohms I can hardly hear a difference switching from Super to Standard. However, when using my higher impedance headphones I can clearly hear a difference in both audio quality and volume. That's definitely what happened in your case, and mine for that matter.
