first of all sorry for my bad english, i’m italian (SHIS).
In these days i’m trying to connect an i2s dac to my Raspberry Pi running Volumio 1.51. The Dac is an AK4399 based board of Audiophonics.
I know that this dac is not in compatible list and there aren’t specific drivers but i want to try i2s for a future use of Volumio with i2s DSP module.
Mclk is provided by a 24.576Mhz TXCO and resample is fixed at 96khz for AK compatibility with this Mclk (and for reduce jitter on Lrclk).
The trouble is on i2s driver on Volumio: there is no way to set any on the available list because Audio Output remains in “Nothing selected”, aplay show “no soundcard detected” message.
Generic i2s driver needs something to detect soundcard?
