16bit 44.1kHz problem (solved)

Postby hardy » 31 Aug 2016, 20:15

I use a Diy dac with a PCM1794 chip on a raspberry pi3, it works fine with 24 bit mp3-44.1kHz , 24bit flac 96Khz and also 24-192Khz, but with standard 16bit CD 44.1kHz, there is no sound.
When I use openelec on the pi, then I can use all the difference music files with no problem, but I wil use RUNE :D
I use the Hifiberry settings.
My DAC is similar to this one. http://www.tjaekel.com/T-DAC/schematics.html

How can I change any settings to solve this problem?

Hi hardy,

From the page you have linked:
The DAC is a TI PCM1794A. It is used with I2S format which supports 24bit (only) and 48..192 KHz.
If we would use the Right Justified format we could support also 16bit samples.


When I use openelec on the pi, then I can use all the difference music files with no problem, but I wil use RUNE

Seems like openelec converts the music to a certain format.
RuneAudio tries to play them bit perfect.

Get access to the console and try to set the output format to 24bit
Code: Select all
redis-cli hset mpdconf audio_output_format "*:24:*"

and reboot to get it active.
