    it says they fixed the bug that the boot up time would become longer.
     
  2. Antihippy
    So would that make the onkyo not too viable for stuff like Google music or Spotify?
     
  3. PoRidge
    the moded OS takes care of the pro audio circuits, like se/balance, h/l gain, acg. that's why you choosw those options in the SYSTEM menu. 3rd party apps do not need to take care of that.

    but IF there is a codec block in the snapdragon soc, 3rd party apps will need onkyo's code/permission to access the sabre dac.

    So will dpx1 soon allow 3rd party app to access Sabres ? :D. It seems SD always have those blocks

    The encouraging thing is they appear to have the hardware right, based on feedback in some areas the Pioneer has a better UI but as they're shared platforms in theory its an easy issue to rectify.....ok anyone involved with coding will know this doesn't always apply! They appear to have  A&K in their sights so again it should be relatively easy to upgrade the UI going forward to address any issues or worst case to allow better access for third party apps. The important thing is they have a great starting platform that only requires firmware/software development rather than engineering revisions. So if Onkyo seriously want to impact the other players in the market they just need to provide continued support, based on current observations of course and hopefully not wishful thinking!

    we don't know if it is using the sabre dacs now.
     
    the X7 uses the dac on all apps. it is up to onkyo now.
     
    another thing that bugs the android os is the mandatory SRC, but i think they solved this already.
     
  7. Replicant666

    Sorry if its a dumb question but what does SRC stand for?
     
  8. PoRidge
    btw, i demoed the pioneer player and found no folder browsing, but some say it does. i may need to check on the pioneer thread fo this.

    sample rate conversion. normally, the android OS will force convert(re-sample) all audio signals to 16/44 using software before sending them to the dac.
     
    but since the dp-x1 can output digital signals of higher resolution, it is not a problem for onkyo.

    Theoretically this is possible.

    However, this is NOT what is happening.

    I have tried, in many ways, and along another Head-Fi'er, to explain this.

    Any and all apps that route audio to Android will mean that, on that device, it's internal DAC will be used.
    Any and all apps that are designed, specifically, to route digital audio to the CPU for modulation will continue to do so regardless of the Android device. Such as Neutron, which is designed, with intent, to BYPASS the hardware DAC for 1st phase digital modulation and use the CPU instead, then use DAC to convert prepared modulation into analogue, and pass to an amp for amplification.

    I cannot stress this enough, this has NOTHING to do with Android, Onkyo, LG (LG V10 has an ESS Sabre DAC).
    These apps, such as Neutron, should NOT be compared to all other apps that use Android to route audio into a DAC. That is the norm.

    As for the System Level functions, which include Volume, Bluetooth, Wifi, etc, Onkyo has made a custom Android OS that has NEW System Level wide functions, AGC, balanced, Line Out, Stand Alone.
    These affect EVERY part of Android, including apps, with the EXCEPTION of apps that deliberately bypass Android and DAC to use the CPU to do software digital audio manipulation. For such apps, some System Level functions may or may not work.
    Neutron is one big example of an app designed NOT to use the DAC in a first instance.

    Please, please contact these app developers for further information and ask if they can modify, or make an alternative, app(s) that will use a DAC first. Or use readily available apps that are not designed to circumvent the norm.

    On Sony ZX2, they added a further cool System Level function, global system wide Android EQ. That doesn't exist on Onkyo DP-X1, only in a single app can you access Onkyo's robust EQ featured.

    The part about the codec block is also partially true, but in the case of both Pioneer XDP-100R and Onkyo DP-X1, when a 'normal' app sends out to Android a digital audio signal, the modified OS will route this direct to the ESS Sabre DAC(s).
    The only time that's not true is with apps such as Neutron.
    The LG V10 has an LG Android system but it operates differently; some core, or LG featured apps, will work like Pioneer/Onkyo. However the custom OS is not designed like aforementioned Android DAP's, so some apps may used standard Android kernel to route a digital audio signal somewhere else.
    LG are in the right direction but has poorer software implementation than Onkyo/Pioneer.
    This is where your points about codec block and Snapdragon apply.

    Thanks for the above explanations , how come Gonemad and jet audio see distortion on dp-x1 ?
     
  12. TheOneInYellow

    Indeed! ONKYO ROCKS! ^^
     
  13. TheOneInYellow
    Heading out to depot to get my DP-X1 (with DPA-GL033 tempered glass screen protector) parcel , will take about an hour or two...
     
  14. Whitigir

    Please report back on 3rd party apps :D

    I think, without actually testing, it could be a combination of Onkyo Android and app sending duplicate protocols on how to decode audio signal, thus noise.
    It could be that one of the new Onkyo Android System Level functions is also causing an issue.
    Remember, very few developers work with nonstandard Android devices, and these high-end Android DAP's are very different.

    Smartphones have been high end tech, low end audio, lots of audio software manipulation.
    This is to do with battery, heat, efficiency.

    These new audio based Android DAP's are very, very new and unique.

    Ask the app developer for further guidance.
