Android phones and USB DACs - Page 126

post #1876 of 4545

Hi Piratair,

 

Firstly Im not sure the Razr can handle a DAC, the s3 can because samsung put in some extra work to make it USB/DAC compliant, it is not a standard feature of googles android at the present, also I have a E17 and it is a problematic USB/DAC even with a samsung s3 (It doesn't work unless you use USB recorder pro).

Piratair, I believe fuzzy1969 is correct, none of the RAZR series can utilize an external USB DAC. Also, although I have not heard that specific model, I've listened to several Motorola devices (Bionic, X, and a few others) and have generally been pretty unimpressed by the audio quality on them. Your model may be different, but in general, I get the feeling that Moto doesn't put a high priority on sound quality. 

 

With that said, I'd say your options are to look at getting a different phone and resume your previous line of inquiry, or keep your phone and get a dedicated player. 

 

If it helps, Fiio is apparently working on a dedicated player (the X3) at a very attractive pricepoint (link). Don't know if you want to wait, but it looks like the X3 might be a way to navigate around your issue and still get access to higher-quality audio while on the go. 

 

Best of luck, bud!!

Samsung Galaxy S3 & V-Moda Vamp Verza USB DAC/amp:

Meizu MX (M032) on Flyme 2.1.2 still does not provide USB audio using the previous hardware. Videos clearly show the E17 capable of SPDIF input (coax and optical), so I doubt it is the culprit. The most likely problem is the MX's inability to power a USB device. I am not sure how to rectify this, or if I can; this may be something Meizu has to fix in a firmware update.

 

I still need to get a confirmed working USB OTG cable and access to a different DAC.

Received the PCstep from Jan Meier earlier and happy to confirm it works with the samsung s3 international version (stock jellybean 4.1.2) including the mixer controls in both poweramp and neutron. edit with or without a battery.

Also had a chance to test the PCstep with the Nexus 7 running the Trinity kernel (Thanks to Swimsonny for the Nexus 7 guide) and it also works.

@ DanBa: Neat looking device!! I'm guessing it's a rebadged Go-DAP X with a pretty hefty price increase. I like the interlocking case though. (Btw, Musica Acoustics has an open-box of the red model for $295 atm if anybody's interested -- link). 

 

@ Fuzzy1969: Awesome, man!! That means it's highly likely it will work with my US version S3. Any comment on the sound? (Mine will probably take a bit longer to arrive... damn oceans tongue.gif).

It only had a few hours burn in and its very nice with both hd650 and c5 (5 driver customs), deep bass. Works best with a battery.

According to AnakChan who has some contact with the VentureCraft people, "there are internal differences.

A mentionable one is the V-Moda Vamp Verza headphone output is almost double of the VentureCraft Go-DAP X".

thank you for your answers even if they have cooled me, if I read the posts of Danba, he said, although it can be done elsewhere I quote his message.

Or I did not understand the interest he Danba enumerate each page of the list of mobiles that can incorporate a dac?
 
But maybe he could tell me and confirm.
For all my thinking rests on it and if I'm wrong, I just goodbye ...
 But in case I have a backup on my brother SG3 he could trade me, but before I want to be on.

In fact I realized that it was thanks to the OTG cable that I could not use my Motorola dac and connect the Apex Glacier behind.
Why do you say that I could not do it? Can if the SG3, I should be able to do after Danba?
And if I have to buy this piece of software what ARP, no worries for € 5 ....
 
Thank Theogene for these incentives.
 
But to be honest I expect Danba confirm your writings, and he explained to me what, I can expect and what I can do with my mobile :)

According to the "USB Audio Recorder PRO website", the Motorola Razr Maxx HD using USB Audio Recorder PRO can interwork with some USB DAC.

http://www.extreamsd.com/USBAudioRecorderPRO/

 

I think it's plausible, because I read that the USB host feature is enabled on the Motorola Razr Maxx HD.

 

I don't include the LG Optimus G on "my" compatibility list, because I don't read that the USB host feature is enabled on the LG Optimus G.

 

 

 

 

 

 

With the USB Audio Recorder PRO solution, there is no more need to implore Android device manufacturers or Google to enable USB audio on their USB host-capable Android devices.

For now, this is what I can say as it's out in the public specs :-

The Samsung-implemented USB enumeration is perfectible.

It is not enough tolerant than the one implemented in the USB Audio Recorder PRO app.

 

The USB Audio Recorder PRO app uses a functional Android USB host driver.

 

The USB host feature is not enabled on LG / Google Nexus 4; a Nexus 4 using USB Audio Recorder PRO can’t work with USB DAC.

 

The incomplete USB host function of the Samsung Galaxy S2 can’t transfer isochronous USB data to USB DAC; the Galaxy S2 using USB Audio Recorder PRO can’t work with USB DAC.

 

Very informative.

It seems that at this moment what we android audiophiles can do are:

 

1. Beg Google to improve android's sound driver for next releases.

Can you propose a vote on Google's "to be improve" list?

 

2. Buy USB DACs with old school chipsets like PCM-270X.

 

3. Buy USB Audio Recorder PRO app, use it with complete USB host mode.

But how can we make sure our android devices are capable of complete USB hosting?

 

4. Beg USB DAC manufacturers to provide a compatible driver, which is most unlikely.

Just wonder if there is an upgrade path with Galaxy S4 being released TODAY.

Sorry noticed the S3 thing is just a metal casing attachment, unlike the VAMP which was custom made for IP4.

DanBa or anyone used the VAMP VERZA or the VAMP before and can comment on it?
