Sorry for bringing this up again Smile

. I just want to understand it and couldn't find anything regarding this.

Looking at the Audio Codec info while playing a song it says pcm_s24b, 24 Bits and sampling rate: 96kHz...but that is just how KODI sends the signal not how it actually is played at the end, right?!

And my second question: What does AE_FMT_FLOAT(15) stand for?

Thanks for outlining!

**fritsch** · 2016-03-12, 23:23

AE_FMT_FLOAT: 32 bit float format. We decode everything to Float internally and then map to the sink. Float has a much larger range than the 24 bit integers the format is shipped in.

Here are some debug logs from the Nexus Player running Android N preview build and Kodi "bisect" build.

24/96kHz Stereo FLAC - output as 48kHz. http://xbmclogs.com/pd8njef7u

24/96kHz 5.1 FLAC - output as 96kHz. http://xbmclogs.com/pouwfy1hu

24/192kHz Stereo FLAC - output as 48kHz. http://xbmclogs.com/pjgnts1xs

24/192kHz 5.1 WAV output as 192kHz. http://xbmclogs.com/parmezk3k

As you can see from the logs, the multichannel output is actually 16-bit. Even this doesn't seem to be happening on the SHIELD.

Yeah - Shield has yet another firmware bug - if you output float everything is 48 khz ...

Can you retry with: http://jenkins.kodi.tv/job/Android-ARM/7555/ on both setups?

Edit: Make sure to set kodi to "Best Match" when testing.

You find the samples on the wiki?

Except for the 24/192kHz WAV all other samples are available here: http://www.2l.no/hires/index.html

I will check it out tonight.

****EDIT****

Checked.

Nexus Player
24/96kHz Stereo FLAC output as 48kHz http://xbmclogs.com/peohk470e

24/96kHz 5.1 FLAC output as 5.1 96kHz (16-bit) http://xbmclogs.com/psgomadzp

nVIDIA SHIELD
24/96kHz Stereo FLAC output as 48kHz http://xbmclogs.com/pcvrt5tqq

24/96kHz 5.1 FLAC output as 5.1 48kHz (16-bit) http://xbmclogs.com/pjex0rnco

So on the Shiled even when Androidtrack says that it opened 16-bit 96kHz 6 channels, the output is 48kHz.

This build also has other issues on the SHIELD.
1) Gamepad controller doesn't seem to work. I had to use a keyboard for navigation.
2) It doesn't seem to remember sources. It is always showing the "First Run" message.
3) After Kodi quits, you get the message "Unfortunately, Kodi has stopped."

Not nice ... nothing I can do ...

For 1) 2) and 3) not related - broken in master.

Horsti143 · 2016-03-16, 18:40

Really sad to hear this, playing HD music would have been awesome using KODI...do you guys know an app like poweramp (which plays my files totally fine btw) that can play via network?

**fritsch** · 2016-03-16, 18:52

Yeah - what about investing in a Raspberry Pi?

Horsti143 · 2016-03-16, 19:34

I have been thinking about going that route as well but I already have a device that can do it..I guess. I just can't use KODI

Bjur · 2016-03-17, 16:03

So will it not be possible to play FLAC on Nvidia Shield at all in the future?

**fritsch** · 2016-03-17, 16:15

Who knows the future? As you might have seen: We don't have an Android Maintainer anymore and nobody is doing Android Development for kodi ... that being said: I have no idea ...

24/192kHz stereo PCM output is possible on the SHIELD (Yes, it is 24-bit) from Google Music Player, MX Player or any other player that uses the NuPlayer. It just doesn't work with audiotrack which Kodi uses. It may even work in Kodi if you use a hi-res USB DAC (I haven't tested this).

Thanks for the replies. I will put my trust in Koying Wink
