Therefore, i’m looking for a extension board that has IIS LVDS output. Luckly, I found this useful discussion (link) and proved its works well.
on the other hand, I can buy the Audio-GD I2S connector module should be easily.
Therefore, the rest question would be Whether RoPieee had I2S driver included/supported?
And i am not quite sure is whether this has conflict with RoPieee disabled HDMI port by default.
I’ve been researching I2S options also with Ropieee.
I was under the assumption that I would have to use something like the PI2AES to be able to achieve this.
I am using Ian Canada HDMI Transmitter directly connected on RPI 4 with Rockna Wavedream DAC via PS Audio i2s (LVDS) mode.
Selecting Raspberry Pi DAC (i2s) as HAT I can play PCM 24/192 and no DSD (tried all the options)
Selecting Audiophonics I-Sabre… I can play PCM 32/384 and again no DSD.
Hope it helps.
I am also looking for a generic i2s driver on Ropieee that can deliver the signal as it is to the i2s.
