I-Sabre kali editio and Allo kali reclocker ( DAC ) Rpi3

Message par foxgenco » ven. 20 oct. 2017 05:20

¿does anyone know how to run the 384 khz or 192 khz using Kodi 15.2 under Raspbian Jessie?

because only displayed on the i-sabre screen 96kHz, while listening to a 384kHz,192 kHz, 176 kHz Flac audio file.
also only the 96kHz led is on under Allo kali reclocker

components:

AUDIOPHONICS DAC I-SABRE ES9028Q2M KALI EDITION
ALLO KALI RECLOCKER I2S FIFO
RASPBERRY PI 3

in the file config i have the line dtoverlay=hifiberry-dac

Hi,

Kodi under Raspbian is not a bitperfect audio system.

You'll be limited by the audio mixer settings under debian.

You can achieve 32/384khz with an advanced kernel and bitperfect software like Moode Audio, Picoreplayer etc ...

well yes, in other distributions like those that you mention works, but I would like to have it work on my already made configuration, since I have customized the whole system.

it seems to have to modify the kernel to be able to add the support of the DAC in debian 8,9 (jessie, stretch) because the dietpi already have integrated the support in the same kernel (4.9xx) , although using their files http://dietpi.com/downloads/binaries/rp ... naries.zip does not work.

Hi,

Yes you're right it seems to be a kernel related issue.

Thanks a lot for sharing your work with the community.

What do you think of the DAC sound ?

Looking forward to hearing from you.
David
