Hi,

it would be really cool to have the I2S enabled Linux kernel in the standard distribution. The patched kernel is maintained by Florian Meier.

I could provide the compiles kernel and modules or I could provide a free HiFiBerry Mini DAC for your own tests:

I would also appreciate this, I hope to use raspyfi with an I2S DAC.
Thank you!

I2S support is now included in the official foundation's kernel :-)
Therefore, it should be available by just "rpi-update"
Would be great if you could test that.

Greetings,
Florian

Hi Florian, nice to see you here. Good to know that is now in the official foundation kernel! I'll give it a try!

So, Florian,
unfortunately the main kernel doesn't seem to recognize the i2s DAC (at least on my PI, which is an older model). So I stick with the kernel you compiled initially for HifiBerry. That does work pretty good. The kernel indeed works pretty good and it can easily play 24/192 both via i2s and USB.
It's by the way included in the next version (to be hopefully released tomorrow)

Hi Florian,

I2S-Implementation for raspberry – great work! Smile I wonder, if it's also possible to connect an CS4334 chip via I2S to the Raspberry. Is there inherent support for any I2S compatible chip or would be a designated low-level driver required?

Regards Andreas
