Only Hi-Res output option is USB-DAC

[Tanq BQZ]

Hi,

Since the last update, there is only USB-DAC in the Hi-Res output section, where there used to be option for the wire/aux and bluetooth. I use the Hi-Res output but I could'nt switch back to it after testing the OpenSL output.

PA version : 945

device : Fiio M11 (Audio Player)

Android 7

The most recent versions of PA do more extensive testing of what the hardware is actually allowing. Even if older builds may have reported that hi-res was working, the Android implementation may still have been capping it. Recent PA builds detect that more reliably. Try resetting Outputs to defaults and then see if you can select hi-res again, or see what higher resolutions are offered by the other output methods (OpenSL ES, AAudio, etc)

Yeah but it's weird since it's an audio player, not an phone. I could choose up to 384 kHz, 32 bits.

I did try to reset to default.

[andrewilley]

@Tanq BQZ apps don't really care what the device calls itself, it's just an Android box as far as Poweramp is concerned - which could be a phone, tablet, car radio, TV, media player, or DAP.

The problem with DAPs (and some other devices) is they don't always use a clean version of Android, and heavy modifications can cause issues for apps expecting the system to behave as per normal Android specs.

If you could provide the latest PA Settings=>Audio=>Advanced Tweaks=>Audio Outputs Detection Log, that might help.

Another Fiio M11 user just recently posted about their device at 24/96k here. 

So something else must be running on yours to restrict it to 16/48k.

[Tanq BQZ]

Just read that thread, he has the same problem, with build 945 you can't use the Hi-Res output for anything other than USB-DAC on the M11. 

Maybe it has to do with the line :

PA tries to read multiple different possible audio_conf files that are found on various different devices. Usually only one will be used on any given device though, so checking for the others too will naturally fail.

We do need @maxmp's input on this though, to say whether the supposed high-res on build 939 was actually working, or if Android was then locking it back down to SD anyway.

Also worth trying with DVC Enabled and Disabled, as some devices don't allow high-res output in combination with DVC mode.

Have a read of Max's replies in the most recent release thread:

Hello, any further updates on this? I recently aquired an M11 only to find I can't use the HiRes output nor can I set anything higher than 48khz. Seem to have the exact same issue as TankBQZ but on version 957 now.

FYI, I'm still on build 939, and I haven't tried more recent updates.

[vipersb1]

I rolled back to 939 and now have high-res access. Thank you!

Hopefully @maxmp fixes this in one of the newer versions....

[ZenHarbinger]

I also have a FiiO M11.

Still Experiencing this bug.  Last version to support high-res output (selection in the UI) was 942.

I had actually updated to the most recent version (as of 6/23/2024) and high-res output works, but the UI no longer allows the selection of high-res for anything except USB-DAC.  So when I was playing with the settings, it would never let me go back to my previous state and had to roll back.

I've had Poweramp for years and so had not played with the settings for close to 3 years, don't ask me why I started last night.

[andrewilley]

I suspect the issues caused when using newer versions of Poweramp are nothing do with actual code changes within the Poweramp app itself, but updating of compilation settings to align with more recent Android SDK requirements as prescribed by Google. As FiiO famously uses older, and fairly heavily modified non-standard versions of Android, there could there could be compatibility issues with apps complied to the latest requirements.

@maxmp is the only person who could confirm that though, if he happens to have any FiiO devices in his testing arsenal of course. 

In the meantime, it might be best to avoid trying to use the experimental Hi-Res feature at all, and perhaps try using AAudio or other output methods which do support higher sampling rates and bit-depths on most devices (although again, FiiO's mods may not help in that regard).

I can help out as much as I can if desired.  I'm not an android developer, but I am a developer.

Thanks!

 

None of the other output options in Poweramp provide anything hither than 16bit/48KHz, but the high-res does offer 24bit and > 192 KHz.  As mentioned, it still works when I was upgraded past 942, but the UI just didn't allow modifications (including loading in old configs).
