The description says that the Khadas Vim has i2s interface, but in the GPIO Pinout does not has it. Where is i2s located? How to configure in Android? Are there software limitations of 16bit/ 48kHz or can it give out sound 24bit/192kHz?
Khadas has “rate_max = 48000” for i2s (and all sound output too) on source.
How to use i2s interface (USB sound and SPDIF too) with 24bit / 96kHz or more for Hi-Res audio?
We use neutron or usb music player, this players have very hight sound quality if use direct control usb DAC to bypass the standard Android driver. But all system sounds and the voice of the navigator does not play if use “direct control”.
When using i2s or onboard spdif, you’ll have to use the standard Android driver. But the standard driver has 16 bits /48 kHz only.
can someone help me. I have a vim 2g/8g with libreelec 8.2.3.1 in mmc, but there is no chance to get the i2s signal. The connection is BCK <> GPIOH_7 (pin 29), DATA <> GPIOAO_9 (pin 31),LRCK <> GPIOH_8 (pin 32), gnd is pin 28. With the vim2 it works, but here no chance.
What can i do ? Thanks
