I have tried but no lucky to have the audio out via dac.
Hi,
I am able to make s2 recognize FIIO e7 as USB audio but I can't redirect the audio stream to the DAC. Does anyone have the cue how I can make it happen?
I just flashed CM9/AOSP and then flashed SiyahKernel again. After connect e7 and s2 with OTG, s2 recognize the e7 and e7 also recognize s2 also.
Hope this information can help.
no, thats not what i'm saying, you really need to do some reading on USB and how it works. All USB devices can either be set to host, or slave. the GSIII is unlikely to be able to be set as slave so we'll just talk about host.
for the GSIII and others to work with something that exceeds the current limit, but has its own power source, there are 3 options.
1. the device tells the GSIII that it has its own power when they are connected, during the signalling used to negotiate device type, speed of connection etc. it does this with a series of logic level signals on the power line. this logic signal may or may not be hardwired and thus not available as a software update
2. you supply power via an external powered hub.
3. you fluke it, the device works anyway despite exceeding the limit, perhaps because during start up it isnt exceeding the power limit, or it lies to the host. this connection may be 'fixed' in an update at any time if problems arise; or the device exceeds the power limit by whatever tolerance is allowed for an extensive length of time and is found out. the phone refuses the connection.
but I only mentioned the FIIO in passing, if at all, because its listed in Kojaku's screen shot posted a few pages back (at least I think it was his) and this confirmed my thoughts as to why some were working and some were not (the 100 mA not 100 mW power limit), for EXACTLY the same reasons that devices work with ipad or not. this is part of the USB protocol, these connections and their power budget need to be negotiated and all things need to be in place for it to work, otherwise connecting your phone to a high power device could overheat or even kill your phone, or at the very least run the battery down in no time.
this seems kind of against the point of having such a rig doesnt it? at that point when you are carrying an android phone, a powered hub and a dac and an amp wouldnt you just be better off using a small netbook or laptop plus a decent USB dac/amp?
Definitely agree there. =)
I don't follow the recent fashion with smartphones and tablets, they're all just huge touchscreens with a very weak laptop inside. 10 years ago mobile phones looked different and had more creative designs, they were more cool and unique.

Tell you what, build me a phone that's as good sounding as my brick amp, brick DAC and that's as powerful as my Thinkpad and I'll be your first customer.
1. Start an interest check / voting thread on how many people want the DX100 to make phone calls, then send an email to iBasso.
2. Glue a Sony Z1070 and Sony Xperia S together.
Just ideas.

So... 5V USB versus 5V external = "now the soundstage is nice and wide", hmm...
Yeah but I wanted good ones and I said 'as good as' not 'worse' what I have.DX100 has enough issues already w/o adding a phone.
Afaik thickness and low battery life seem to be caveats with all the top-flights, Colorfly C4, HM-801, DX100.
Haven't heard the Z1070 but if the Xperia S sound and reviews are any indication it should sound more exciting than a Wolfson chip or Hifiman.
IIRC you used an iPhone before, there is the V-moda VAMP as well.
