Only Hi-Res output option is USB-DAC

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)

@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.

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:
