    Have you tried resetting Audio > Outputs to default settings (or even clear app data, and let it set everything up from scratch)? Also try with DVC enabled or disabled.

    The Fiio range uses fairly heavily modified versions of Android, and highly non-standard hardware, which I believe makes them something of a niche moving target spec-wise. I don't know if @maxmp has an M15 for testing purposes. He does have a wide range of devices but obviously can't have one of every Android device that's ever been released.

    Also, you first mentioned this M15 issue one month ago, and there hasn't been a new build created since then. I'm sure this will be on Max's radar for the future, but currently all of his development time is going into the project to enhance PA Equaliser's and make it available as a stand-alone product (due later this month).


    Hello André, thanks for replying. I had already tried dvc on/off plus all sorts of other stuff (no idea where to find the -clear app data- that you mentioned though, can you let me know?). What I did not do is -restore defaults-. I don't know anymore which ones I tapped on, apart from audio output, but the end result is that the frequent distortions disappeared. So the sound seems allright now. As long as I keep the preamp of the EQ at a minimum. And as long as I don't give it too much bass. I still have the impression that UAPP is more clear, bright, transparant, more effortless. Admittedly, that may be in my head after listening to so many tracks that did not come out well via Poweramp.

    You describe the Fiio range as a technical niche and for that reason hard to crack for true HiRes output. However, Poweramp did facilitate HiRes output for last year's M11. Since then the Android version has not changed (it is still 7.0) and the Exynos 7872 processor is still in use. What has changed (apart from other stuff surely) are the DAC chips. They have gone a step up, the M15 has two AKM AK4499EQ. Since you've done it before it is perhaps a bit less complicated to make Poweramp M15 compatibel as well. I really hope Maxim can find a moment to look into this.

    Many thanks.

  2. For months now Poweramp is not a HiRes music app on my player, the Fiio M15. I have to use another app to get the sublime audio that this player is capable of. Poweramp sounds mediocre on it. And when I activate HiRes output much is distorted, no matter what settings I try. How come other apps can do what Poweramp cannot? I really would like to know: is it that difficult to make Poweramp work properly on the Fiio M15? As good as UAPP and the Fiio Music app?


    I did put down a request for HiRes support in the other thread, with all the audio specs, but without receiving any reply. 


    Poweramp has by far the best UI of all the music apps I know and I hate not being able to use it anymore. 

  3. Since request and audio specs were sent seperately the last time, I'd like to ask again for HiRes output for the Fiio M15, this time with the audio details attached.

    Would you please please make this possible? The Poweramp interface is the best there is, but the sound is best with UAPP. Do they have a secret weapon or can Poweramp make the Fiio M15's HiRes output just as good?

  4. Fiio M15 with Android 7.0


    DAC AK4499EQ x 2 XMOS 768kHz/32 bit


    High-Res output can be made active but the sound is distorted in the lows and especially with the letter S. No matter what settings/sample rates etc I choose.

    You made the previous Fiio M11 sound great. Hopefully you can do the same for the Fiio M15. Thanks.

    (Sorry I have no idea where/how to find the specific Android files you ask for.)


  5. Yes, disabling DVC has helped (playing music over spdif (coaxial) in HiRes). Though I still have to also launch the standard music app on the Fiio. But thanks for the suggestion.

    The other thing I mentioned before, would that be doable? The eq setting linked to the coaxial output? It is now stuck to the assignment "wired headset".



  6. Sorry, forgot to add that it is my Fiio M11 that has the spdif option.

    Also, when Poweramp is set to HiRes output it falls silent when I switch the DAP to spdif. Though sometimes it does work when I also launch the originial Fiio Music app. But strangely enough not always. When I  switch Poweramp to one of the other outputs there is sound coming through. Can't Poweramp access the Android output so that it can play in HiRes over spdif?

  7. Poweramp seems to provide high resolution audio, but it doesn't. At least not for my Pioneer XDP-100R. When I reported this, in april 2016, I was asked to send a few technical files so that the HiRes output could be facilitated on my DAP. I did, hoping that that would solve the matter.

    Never to hear from it again. Despite repeating the question several times over the years. The request is simply ignored.

    Could you look into it again please? It really is so disappointing to see the message FAILED: Hi-Res OUTPUT. Every single time I start Poweramp. Especially since I know it is possible of course. Apart from Pioneer's own music app there is Neutron as well as USB Audio Player PRO that provide it as well. I switch to UAPP regularly because of the better sound quality, but they have other issues, so I stick to PA for now. You would do all users of this DAP a big favor I'm sure!

  8. Thanks for your reaction Andre.

    Using Build 826 now.

    In answer to that:

    I said I had put the playlists in the root of the internal storage. To be precise: all the individual playlists are on the same level as the folders ANDROID, DCIM and so forth. The path is /storage/emulated/0/Playlists. Maybe that is not the same as the root, I'm no expert. The reason I did that is because I could not put them in a folder, using File Explorer on a Win10 laptop. No idea why. I can copy an mp3 to it, but no m3u8. The fact that all playlists were floating around folderless is also the reason why I had to designate the entire Internal Storage as a music folder. Whatever I try, this problems persists. Maybe it is a Windows thing, or Android.

    Following your warning about file based playlists, I made new playlists from within PA, copying all entries from the file based ones. Exported them. So that will be new the method.

    I have done a full rescan. And only recently I reinstalled V3.

    Other than you expect perhaps, I do have 2 micro sd cards working in tandem, containing only music, and that works fine. Pioneer XDP-100R.

    Since I mention the brand of my DAP... Years ago (April 2016) I asked PA to facilitate HiRes output for this device and I sent the relevant files (audio-policy, build-prop). Never to hear from it again. Despite repeating the question. Could you look into it again please? It really is so disappointing to see the message FAILED: Hi-Res OUTPUT. Every single time I start Poweramp. Especially since I know it is possible of course. Neutron as well as USB Audio Player PRO provide it. I switch over to the latter regularly because of the better sound quality, but they have other issues, so I stick to PA for now. You would do all users of this DAP a big favor I'm sure!


  9. Those songs are only missing from the playlists, they exist.

    Some of the remaining songs are from SD card 1 as well as 2. So it is not always just the songs from one card missing.

    Having just created a new playlist in PA I am beginning to doubt whether I have done that with the playlist called 'set' that has entries missing. I know I have made a number of playlists in JRiver and copied them to the DAP (after editing to create the right pointers). This was before I made my DAP my main music center. So I delete songs in PA and create/modify playlists in PA on the DAP. A few times a year I copy the whole lot to my laptop as a backup. The JRiver playlists worked for a long time without a problem. In the past months, probably after a PA update, I lost several lists enterely. Some came back after a full rescan. But I think I have had to restore several lists from my backup. I didn't keep track of what I did in order to make it work again, being happy the problem seemed solved.

    When I backed up the playlists from my DAP I did so my copying the lists in Windows Explorer. That seemed to be working. Songs added from within PA showed up in the playlists when I checked after copying/backing up. So restoring followed the same route. Copy paste. Not via import/export.

    Working on this issue, since you asked, I opened a playlist in Notepad. This list, as all others (except for the new 'test' list I just made) are sitting in the root of the internal storage. It shows about a 100 songs, but only 13 show up in PA. All the missing ones are on SD card 1. Though that is selected in music folders and I have done a full rescan. In the other case I mentioned it was less clear cut, because it still contained songs from SD card 1. In settings-music folders I first unchecked the internal storage where the playlists are located. The automatic scan followed, rendering all playlists absent (except the 'test' one I just created). And then I selected the internal storage again. After the ensuing scan it brought back the missing songs in the playlist mentioned above. But not the ones missing from 'set'. In this case are was also no difference between the list in Notepad and in PA.

    As music folders I have, as always, selected the entire internal storage, the entire SD card 1 and the entire SD card 2.

    One playlist shows yet another issue. Opening it in Notepad gives 19 songs. In PA however I count 23 songs! The difference are 4 songs at the bottom of the list in PA, all recent additions. But where are they stored? So there is a difference between what was imported/copied and what was added from within PA? But why do the recently added songs show up in one list and not in another ?

    Yet another playlist shows the following: I recently added 14 songs to it, from within PA. I see them on my DAP screen. When I look at the playlist in Notepad however I see only 2 recently added songs. After that there is a partial reference only:


    /storage/sdcard1/Hanne Hukkelberg/Rykestrasse 68/07 Break my Body.mp3

    /storage/sdcard1/Hanne Hukkelberg/Rykestrasse 68/09 Pynt.mp3





    The only irregular symbols in the playlists are underscores in stead of a space.

    In the internal storage I also have folders from Neutron and from UAPP. Could they interfere?

    Only 5 gb used of the 25 available on the internal storage, so that can't be it.

    The playlists I have are a mix of .M3U and .M3U8. Though the content seems the same to me.

    Could the fact that I have 2 SD cards of 400 gb play a role?


    Hopefully this brings you a bit further.





  10. Indeed it has happened before after an update. Some playlists gone entirely, others wiped (almost) clean. This time no lists have gone but a series of entries in at least one particular list have. This is definitely recent since I often play from this list. I created the list within PA and added to it from within PA. All my lists are .M3U. In the course of the existence of this list I have copied it back and forth to my laptop. Either to make a backup or to restore it after another destruction by a PA update. Not sure if anything changes during this process, don't think it does. In any case, this time round the playlist is still there, only curtailed.

    Maybe there is something in the following: I also USB Audio Player PRO (UAPP). The reason for this, by the way, is the fact that Poweramp had never implemented HiRes for my Pioneer XDP-100R, though I have asked for it 3 years ago. Anyway, this player also has an issue with playlists on my DAP. It does not show them the regular way. I have to go to the root, tap on a list and watch a conversion/parsing process into something that can be read by the software. I cannot add to a playlist. This parsing has to happen every time. I noticed that one playlist has 250 songs in it in UAPP but only 69 in PA. More playlists have this discrepancy.

    Looking into it further I also noticed that UAPP does show songs from SD card 1 as well as SD card 2 while PA only displays songs from SD card 2 in the PA playlists with this difference in number of songs. Could that be something? Though it does not explain why one particular playlist has lost a series

    I have done a full rescan after the update. The cards have not left my player for a while.

  11. Playlist entries have disappeared since update 823 and remain so after a full rescan.

    This makes me sick. So much work goes into making these lists. All for nothing. Only a portion is retrievable from the latest backup.

    The additions to the playlists were made from within PA.

    Is there a way to stop updates from destroying my files?

  12. Almost 3 years (!) ago you asked me to send the details of my Pioneer XDP-100R, so that HiRes output could be facilitated on it.

    I have waited for the arrival of Version 3 of your software. I had expected it would finally make it possible.

    But no.

    I still get the message FAILED: Hi-Res OUTPUT. Every single time I start Poweramp. I am using build 816.

    Meanwhile I downloaded USB Audio Player PRO. While it lacks many elements of Poweramp, it does provide HiRes output for my DAP. The same goes for the app that came with the DAP. But sofar I prefer using Poweramp.

    May I ask you again if you can make HiRes output work on the Pioneer XDP-100R?

    /etc/audio_policy.conf  is the full path description to the file - i.e. from the root level of your device's file system, open the etc folder and insde there you will find a file named audio_policy.conf


    Hi Andre, Thanks for checking if HiRes can be added in Poweramp for the great Pioneer xdp-100r.





  14. Pioneer XDP-100R

    Android 5.1.1

    Processor Qualcomm APQ8074PRO-AB

    This is a dedicated HiRes audio player that plays all possible HiRes files through its own Music app. However, some of these do not play through Poweramp, a player that I find much better than the standard Music player and that I use all the time. These files are (I give the content of what is in the tag info) :

    AIFF at 192 kHz 24 bit 9216 kbps does not play at all (I see the warning : failed to play file)

    PCM_S24BE 96kHz 32 bit 4608 kbps does play but with constant static (dvc on or off)

    PCM_S24BE 88.2kHz 32 bit 4233 kbps does play but with constant static (dvc on or off)

    PCM_S24BE 48kHz 32 bit 2304 kbps however does play correctly
