I did fix the sound settings, also im going to purchase a 3,5mm to rca x2 cable.

Do you guys know when the x1a will arrive @ EU?

we need someone else to try with root to be sure it's working on highres support, since only xVortex wrote he did it; maybe something changed since the last onkyo update.

Ok I succeeded the solution was to give permissions to the dummy file "If it still doesn't work, you have to set the permissions of the audio_hifi.conf dummy to 0664 (rw–r–r)."

So for now Poweramp alpha version is working.

yeah , tried that.. the unit has now been sold , i am very happy with a new fiio x5 gen 2 and an amp strapped to its back , its lod enough for me now , the onkyo didnt cut it and is too quiet for me ,

Good to hear it, i still have hope that Max will  add the support in the official poweramp release; i don't want to root my DP-X1

Doesn't re-routing the audio server require a root level application?
 
I know when I was trying some command line changes for Viper4Android, they were affecting files on the System partition, which required root access to make read/write - before the changes could be made.

As far as i know, nope; since an application just need to read on proprietary file system, not modifying.
 
poweramp programmer need to call the correct libraries to have high-res support using ESS, it's why he asks about audio_policy.conf file, he can find reference on libraries call on specific DAC hardware and it's why more and more users are complaining that high-res hardware support is not working under android 7.0 but was working under android 6.0
 
Google changed the file of audio configuration to .xml format:
https://source.android.com/devices/audio/implement-policy.html
 
i still suspect one thing on third parties audio players (but i don't have proof of that, just guessing):
 
i'm not sure they use ESS9018K2M as DACs but rather the Snapdragon integrated DAC, that's also capable of high-res playback, poweramp gives that string on description (maybe is just a description, not the real support)
 
ESS6901K are always used as headphones amps, that's quite easy to find, balanced AGC works even playing Youtube videos or any other audio player.
 
So until, we don't have a specific support (i tried to write to Foobar mobile but they deleted my post, too many links

 ) to compress-offload-playback , i doubt ESS9018K2M are used or at least they are used only as low latency device 48000Hz/16bit

looking for some recommendations for over ear headphones for the DP-X1. Something good sounding (rock, metal) that will not require a separate amp. Thanks in advance.

I use my PM3s with it and sounds great SE or Balanced. If you like Planar sound you should get them.

Regarding foobar it is working but of course they use the regular DAC
 
http://forum.foobar2000.com/forum/showthread.php?596-flac-sacd-24-bit
 
I got a question If I use the modified Build prop do you think the Onkyo player is still recognizing the player as onkyo and subsequently use the Sabre DAC?
 
also when using Poweramp with the mod I think the volume went way down and both amp as balanced are practically a requirement also regarding viper4 android first of all it wont wok with anything above 44/ 48 KHZ
 
https://forum.xda-developers.com/showpost.php?p=70342538&postcount=24463
 
plus I noticed viper4 android is adding some kind of scratchy background noise floor not very nice to ear.

 

[IronFly]

yes, i know Foobar works but i sent an email and tried to post on their forum to ask if there will be any specific support for the DP-X family's hardware.
 
Onkyo stock player will always use the correct hardware, since it has the correct libraries calls; the ro.product.manufacturer mod is just to fool poweramp device check and enable highres "hardware" support on unlisted/unsupported manufacterer. 
 
viper4 android is just a software ehancement, like Dolby or BBE on Cowon device, so no hardware support for the DP-X1

Viper4Android is just a software signal processor, but it works at system level to "EQ" most/all apps, hence the need to be in Permissive mode for the MediaServer to work that way.
 
These are the commands that I was talking about, that required root access (they supposedly change the supolicy of SuperSU):
 

su
mount -o rw,remount /system
cd /system/su.d
echo '#! /system/bin/sh' > 50viper.sh
echo '/system/xbin/supolicy --live "allow mediaserver mediaserver_tmpfs:file { read write execute };"' >> 50viper.sh
chown root.root 50viper.sh
chmod 755 50viper.sh
cd /
mount -o ro,remount /system
exit 

 
Take Care,

​at home or on the go?

Is there a silicon case for ONKYO DP-X1  ?

  Is there a silicon case for ONKYO DP-X1  ?  

Does a Google search for - "silicone" "DP-X1" - return any results for cases other than real or synthetic leather?
 
And the answer is, No.
