Hello, i have Philips Android TV with kodi obviously installed on it, and i mainly use it just for music.I use the optical out on my tv with an external DAC (toslink to rca converter) to an old amp which has only rca in. Now I was curious what are the best settings in kodi. I have it set on fixed output 192Khz (my dac is up to 192khz 24bit) no stereo upmix, i enabled passthrough with all of the dts and dolby options off, and i use 2.0 as number of digital channels at the top. Some of my music files are 320kbps mp3, a lot of them are flac, and not much are flac at 192khz. I'm i missing something in the settings, or all is well, if any has more experience with setting up audio in kodi i would like to hear some advice. Thanks

It's likely that the android tv hardware restricts/limits the audio files in some way. My Amazon Fire TV box, for example, outputs all audio at 48kHz. So I have left the Kodi setting as "optimised". It is unlikely that you will achieve bit-perfect throughput of the audio steam to your DAC if that is what you were after.

You are probably right about it being a driver issue, but if there is no available driver to output 32, 88.2, and 176.2kHz, it may just as well be a hardware issue.
Incidentally the windows pc also has HDMI audio out where all sample rates are shown as available including 22, 32, 44.1,48, 88.2, 176.4 and 192.
I suppose KODI is just trying to make the best compromise with its audio decisions. It is better that music plays after being resampled than to not have certain sample rates not play at all.
I have digitised most of my vinyl collection, using "Audacity" and I have found that the resulting digital files sound as near identical as I can tell when playing the LP digital and original vinyl versions. I used the same turntable and pre-amp to record the LPs as for playback. There is no reason why the sound from the digital file should not match the LP if the equipment chain and volume level are as common as they can be.
