Pros: This card appears to be a clone of the "HifiBerry Digi+" card supported by Raspbian and works perfectly with a RaspberryPi2 Kodi media center using an external DAC. Setup took about five minutes following the HifiBerry guide "Configuring Linux 3.18.x": (1) Enable SPI and i2c in /etc/modprobe.d/raspi-blacklist.conf - comment-out "#blacklist spi-bcm2708" - comment-out "#blacklist i2c-bcm2708" (2) Remove stock audio driver in /etc/modules - comment-out "#snd-bcm2835" (3) Add device tree overlay in /boot/config.txt - add "dtoverlay=hifiberry-digi" (4) Make this card the default ALSA device in /etc/asound.conf - add "pcm.!default { type hw card 0 } ctl.!default { type hw card 0 }" (5) Unlike HifiBerry Digi+, this card includes an IR receiver for remote control. However, there's GPIO conflicts, Since CEC works over HDMI with Kodi, I had no need for the "lirc" IR remote control framework. So I disabled "lirc" to prevent conflict with GPIO26 (GPIO header pin 37): - To disable: in /etc/modprobe.d/raspi-blacklist.conf, add "blacklist lirc_rpi". - To enable: in /boot/config.txt, add "dtoverlay=lirc-rpi,gpio_in_pin=26,debug=on" After a reboot, the card is enabled: npm@kodipi:~$ aplay -L null Discard all samples (playback) or generate zero samples (capture) sysdefault:CARD=sndrpihifiberry snd_rpi_hifiberry_digi, Default Audio Device npm@kodipi:~$ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: sndrpihifiberry [snd_rpi_hifiberry_digi], device 0: HifiBerry Digi HiFi wm8804-spdif-0 [] Subdevices: 1/1 Subdevice #0: subdevice #0 Select this device in the Kodi media center and all playback will occur over SPDIF. A big advantage of using this card over USB audio with Kodi is that the default Kodi setup always resamples to 48k over USB; with this card, the exact sample rate of the video or audio files are output to the DAC, even 192kHz/24 bit files.

Cons: Doesn't include four "M2.5x12mm" spacers and screws to mount the card securely to the Raspberry Pi 2. Without a spacer, it is possible for the weight of the SPDIF cable to bend the card towards the RaspberryPi2, potentially shorting the SPDIF transformer to the HDMI connector. In a hurry to get this working, I found a ceramic spacer that doesn't quite fit, but at least prevents the board from accidentally touching the RaspberryPi2 connectors.

Overall Review: Unlike the HifiBerry Digi+, this card comes with a SPDIF transformer "standard." (however, the transformer equipped Digi+ cards are not available in US/Canada). It also comes with an additional IR remote control functionality. All that extra functionality and features ends up costing less than half the price of the HifiBerry Digi+ after shipping and taxes! This is a great deal for a well-manufactured board that is fully supported by Raspbian.

Pros: Worked "out of the box" recognized as DDR3-1600Mhz but with slow timings. Passed Memtest86+ once at default "out of box" speeds. Passed Memtest86+ three times (5hrs) w/ custom timings 9-9-9-27-36 1T @ 1.65v

Cons: Had to manually set timings and voltage to get rated speeds XMP-1600 : (800 MHz) 9-9-9-27-36 1T @ 1.65v

Overall Review: The ASUS M4A78t-e Mobo supports overclocking memory at XMP-1600 : (800 MHz) 9-9-9-27-36 1T @ 1.65v using AMD Phenom II 955 Black Edition 3.2Ghz
