I want to build a nice sound server to pair with the very nice audiophile dac base on pcm1704 that i am building : diyaudio.com/forums/musicalt … m1704.html
It have the classical input, usb-spdif-AES/EBU, and also the new i2s over hdmi promoted by psaudio. Also, some brand start to integrate this promising interface in their dac, like aune or audio-gd, who also offer a cheap input/output diy board : audio-gd.com/Pro/diy/I2Skits/I2SEN.htm
I just get this new audio-gd output board, and now i start to see if i can use it. I see that volumio support i2s output in the raspberry pi, but it’s seems a wrong choice for bitperfect playback with it’s clock limited to 19 mhz : hifiduino.wordpress.com/2014/11 … tal-audio/
Insted the cubieboard look like a good choice with a nice i2s implementation : hifiduino.wordpress.com/2014/03 … for-audio/
“Audio_PLL is the audio frequency clock derived from the 24MHz system clock. The PLL generates the 24.576 MHz and the 22.5792 MHz clocks. This means that the A20 is capable of bit-perfect playback for both the 44.1KHz and 48KHz family of sample rates.”
“The A20 processor has excellent support for bit-perfect I2S digital audio. However, only the CubieTruck board allows access to the I2S pins.”
Also, i2s seems supported by the community of cubieboard, they had developp an i2s alsa driver : cubieforums.com/index.php?topic=1081.0
So i see that the cubietruck is supported by volumio, but dos it support i2s out ? If yes, do you think it work if i just connect my audio-gd board to the i2s pins of cubietruck ?
Last question, cubieboard guys just release a new board, the cubieboard 4 that looks badass Do you plan to support it ?
