Thanks to @maxmp . Problem Solved . My OPPO R17 pro in Oreo running it very well !

1. OPPO R17 pro 2. oppo modified Android 8.1 3. It use Qualcomm Snapdragon 710 Edited : I uploaded right audio_policy .conf file in a floder named "Updated". Sorry for uploaded a wrong file. USB DAC is work oddly. My USB DAC should be 24bit 96khz. Screenshot is in a floder named "Usb dac". https://drive.google.com/folderview?id=1MY2gTaO26pTzgXo-tbGXhydkB3hwW6_H

Sony Xperia X with Android 7.1.1 Recently Sony updated my phone ,although hi-res shows up again ,but it's still unusable. https://drive.google.com/folderview?id=0B9umxzt2pQnFc2Q1UHdxODEzV28

Yes ,Android's Doze is a battery boost application , although it don't stop Poweramp , but will pause Poweramp's activity . When Doze mode is activated ,Android will ignore the wake lock. The only way is add Poweramp to Doze's white list . It looks like : https://drive.google.com/folderview?id=0B9umxzt2pQnFVkZ1ODdGUkZaYUU

My Xperia X with Nougat didn't have same problem . Poweramp needs to run in background at first , if Poweramp is stopped , auto start/pause won't work. Does your phone have task management app (that will stop Poweramp automatically)? Does you using battery boost app (that will stop Poweramp automatically)?

To Rubenesque : Please check Neutron's Auto Launch setting is off , and reset Android's default launch options , then try it again . I have Neutron too , and had similar problem before .

Sony's Android 7.0 changed alot , so l decided to paste a link , that linked to a compressed entire /etc floder . https://drive.google.com/file/d/0B9umxzt2pQnFQmd5VlZ1dG5VTkk/view?usp=drivesdk

I had posted one in the High Res Requests thread , my xperia x had same problem.

Now I know why the 704's hi-res can't use on xperia x with Android 7.0 . Because Sony don't use audio_policy.conf file but newly provided a audio_policy_configuration.xml file , made the Poweramp app can't got audio_policy.conf file . Please fix it , thanks !

1. Sony Xperia X F5121 2. Android 6.0.1 3. Sony says Xperia X & X Performance support Hi-res audio_policy.conf It not just support 24b 96k. I've tested 24b 192k with Poweramp v3 703 (google) successfuly .

I found out that: My xperia x truly support 24b 192k . Can't use Poweramp default value.

It work best on xperia x while manually setting 24bit 96khz . (the version number is 703) Android seems resampled 24b 192k back to 24b 96k . Sounds not as same as quality while i manual set to 24b 96k Suggestion : If device not supports 24b 192k ,but supports 24b 96k ; Let Poweramp select the 24b 96k.
