JeffP Posted June 29, 2020 Share Posted June 29, 2020 I have a new Fiio M6 and purchased power amp v3. Everything seems to be defaulting to 16 bit/44Khz output, even when playing Hi Res (24 bit/96KHz) files to either wired headphones or wireless phones connected via Aptx HD. In Poweramp, when I go to Settings>Audio>Ouput> Hi Res Settings, the only option visible is USB DAC. I don't see the Wired Speaker/AUX, Bluetooth, etc. options that appear in the Open ES and AudioTrack output menus. Any help would be appreciated. Thanks!

Thanks! i dont think the m6 supports Hi Res on bluetooth, not working on my m6. But you should have it with cable. Quote Link to comment Share on other sites More sharing options...
JeffP Posted July 3, 2020 Author Share Posted July 3, 2020 Thanks. I updated the firmware to the latest (Poweramp-v3-build-874-uni.apk) and the wired connection now shows up and outputs 24b/96Khz. The version on the FiiO site is many versions older. Quote Link to comment Share on other sites More sharing options...

andrewilley Posted April 20, 2021 Share Posted April 20, 2021 To what? Could you let us know the problem you are experiencing, and what device/firmware/Poweramp version, etc? Andre Quote Link to comment Share on other sites More sharing options...
JeffP Posted April 20, 2021 Author Share Posted April 20, 2021 The original question was regarding 24/96 resolution using Poweramp on the Fiio M6 over AptxHD. While I can get this resolution over headphone or USB outputs, it seems to be limited to 16/44 over AptxHD. I am using the latest version of Poweramp (893) and the M6 is running the lates firmware. Any help would be appreciated. Thanks, Jeff Quote Link to comment Share on other sites More sharing options...
andrewilley Posted April 20, 2021 Share Posted April 20, 2021 Support for high-res and more recent Fiios was introduced a while ago (build 838 I think)but not sure whether that included the M6. You say you've already updated the Fiio firmware, which I was going to suggest. Latest Poweramp here in the forum downloads is build 905, probably won't make a difference but shouldn't do any harm either. Try turning Bluetooth DVC off for this device and see if that helps (or turn it on if it's off). Might also be worth looking into Android Settings > Developer Options > Bluetooth settings. e.g. make sure Disable Absolute Volume is ticked, and try different AVRCP versions and adjusting HD/codec/sample rate/bits.

maxmp Posted April 21, 2021 Share Posted April 21, 2021 @JeffP on FiiOs, you may need to disable DVC (either globally or via output No DVC option) to get Hi-Res. Though, situation with the DVC may change depending on firmware. Quote Link to comment Share on other sites More sharing options...
JeffP Posted April 21, 2021 Author Share Posted April 21, 2021 Thanks for the prompt reply. I tried disabling DVC. For a 24/96 file, using Bluetooth (aptxHD) the resampler is down converting from 96K to 44KHz and the OpenSL ES Output is 16/44. Doesn't seem to change no matter what I do. When I plug in headphones, the resampler is upconverting to 192kHz and the OpenSL ES Output is 24/192. Is there a way to keep the resampler from down converting when using bluetooth?

andrewilley Posted April 21, 2021 Share Posted April 21, 2021 Why are you using OpenSL ES rather than Hi-res, is that not available on your device? (Fiio's use pretty heavily modified Android variants, so I guess it might not be possible of course) Andre Quote Link to comment Share on other sites More sharing options...
JeffP Posted April 22, 2021 Author Share Posted April 22, 2021 That's been the problem since day 1. When you go to the Hi-res output, the only options that show up are wired headset/aux and USV DAC. No option for bluetooth. Is there no way to set the resampler manually? Thanks, Jeff Quote Link to comment Share on other sites More sharing options...

Thanks, Jeff That´s the problem... 😞 and Open SL I´m afraid isn´t the best way. Are you playing AptxHd on Fiio Music player ? I have to say default player it´s a rubbish Quote Link to comment Share on other sites More sharing options...
JeffP Posted April 26, 2021 Author Share Posted April 26, 2021 Yes, but as you said, the sound isn't that great. To me it sounds better using Poweramp at the lower resolution. So I guess that is where we are at.... Thanks for your help. Jeff Quote Link to comment Share on other sites More sharing options...
maxmp Posted April 26, 2021 Share Posted April 26, 2021 @JeffP you probably perceive default -6dB "headroom" for non-dvc mode as "not great". It's known that most humans perceive louder sound as "better". In blind tests, 128kB mp3 +6dB will win vs 192kHz/24bit flac 0dB. So if you may start with Flat equalizer and Bass tone on 0 + headroom set to 0dB ("No DVC Headroom Gain" option) for the fare comparison.
