Passthrough does not work for audio 44100Hz with HiMediaPlayer

[qqq1971]

There was posts about the problem. Just another one. Player connected through HDMI to AVR. All settings - passtrough (HDMI - RAW, HBR Output - RAW 7.1)

Flac file with correct playing (source 88.2kHz, AVR shows 88.2kHz, volume can not be changed from pult):

1. Settings for HDMI - passtrough. Why player uses *Engine(PCM)?
2. Why player does resampling audio?

@futeko, please send a bug to HiMedia.

Has been reported already and  is known. Also valid when playing simple MP3 audio files and probably any other format at 44100Hz

When all Video problems are solved (and we are getting close to that) there is hope that other matters get some attention: HQ Audio, HDMI-CEC, Samba Server, File Browser etc etc. Still enough to be done to make it the best player around.
