  1. So just to report back for posterity. I've tried the latest 5.18 kernel for the 'rolling' build on https://www.armbian.com/rock64/. No luck with the DAC HAT, audio out the 3.5mm jack no problem. Back to the legacy kernel for me... The list of devices looks promising, but none of them produced sound out the i2s HAT. # aplay -l **** List of PLAYBACK Hardware Devices **** card 0: Analog [Analog], device 0: ff010000.i2s-rk3328-hifi ff410000.codec-0 [ff010000.i2s-rk3328-hifi ff410000.codec-0] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: HDMI [HDMI], device 0: ff000000.i2s-i2s-hifi i2s-hifi-0 [ff000000.i2s-i2s-hifi i2s-hifi-0] Subdevices: 1/1 Subdevice #0: subdevice #0 # aplay -L null Discard all samples (playback) or generate zero samples (capture) hw:CARD=Analog,DEV=0 Analog, ff010000.i2s-rk3328-hifi ff410000.codec-0 Direct hardware device without any conversions plughw:CARD=Analog,DEV=0 Analog, ff010000.i2s-rk3328-hifi ff410000.codec-0 Hardware device with all software conversions default:CARD=Analog Analog, ff010000.i2s-rk3328-hifi ff410000.codec-0 Default Audio Device sysdefault:CARD=Analog Analog, ff010000.i2s-rk3328-hifi ff410000.codec-0 Default Audio Device dmix:CARD=Analog,DEV=0 Analog, ff010000.i2s-rk3328-hifi ff410000.codec-0 Direct sample mixing device hw:CARD=HDMI,DEV=0 HDMI, ff000000.i2s-i2s-hifi i2s-hifi-0 Direct hardware device without any conversions plughw:CARD=HDMI,DEV=0 HDMI, ff000000.i2s-i2s-hifi i2s-hifi-0 Hardware device with all software conversions default:CARD=HDMI HDMI, ff000000.i2s-i2s-hifi i2s-hifi-0 Default Audio Device sysdefault:CARD=HDMI HDMI, ff000000.i2s-i2s-hifi i2s-hifi-0 Default Audio Device dmix:CARD=HDMI,DEV=0 HDMI, ff000000.i2s-i2s-hifi i2s-hifi-0 Direct sample mixing device
  2. Thanks, the tip, i forgot about the 'legacy' kernel images. I've booted the most recent build i could find Armbian_21.02.1_Rock64_focal_legacy_4.4.213 and now have audio working. `aplay -D default:CARD=rki2ssound piano2.wav` will play out of both the onboard 3.5mm headphone jack, and the DAC HAT. I'm sure i had it working before (2+ years) ago using the mainline kernel. Either things have changed since then, or my memory is faulty. I see rock64 has more recently moved from CSC -> WIP and there are some new builds. Will try those out and see if things have changed.
  3. Hello, A while back i was using my rock64 as a media player running armbian with some success. Since a hiatus and reinstall of the latest armbian focal mainline release, the i2s output no longer works. I can get output on the 3.5mm jack, but not on the RCAs of the DAC board. I spent some time playing around the fdtget/fdtput with no success as i don't really know what i'm doing in that space. Does anyone know how to enable I2S? Volumio got mentioned allot in my google searches, so i tried that and viola the DAC works again. volumio@volumio:~$ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: HDMI [HDMI], device 0: ff000000.i2s-i2s-hifi i2s-hifi-0 [] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: I2S [I2S], device 0: ff010000.i2s-rk3328-hifi rk3328-hifi-0 [] Subdevices: 0/1 Subdevice #0: subdevice #0 card 1: I2S [I2S], device 1: ff010000.i2s-snd-soc-dummy-dai snd-soc-dummy-dai-1 [] Subdevices: 1/1 Subdevice #0: subdevice #0 card 2: SPDIF [SPDIF], device 0: ff030000.spdif-dit-hifi dit-hifi-0 [] Subdevices: 1/1 Subdevice #0: subdevice #0 volumio@volumio:~$ uname -a Linux volumio 4.4.154 #1 SMP Tue Oct 13 11:37:38 CEST 2020 aarch64 GNU/Linux on armbian i get **** List of PLAYBACK Hardware Devices **** card 0: rockchiprk3328 [rockchip,rk3328], device 0: ff000000.i2s-i2s-hifi i2s-hifi-0 [ff000000.i2s-i2s-hifi i2s-hifi-0] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: rockchiprk3328 [rockchip,rk3328], device 1: ff010000.i2s-rk3328-hifi ff410000.codec-1 [ff010000.i2s-rk3328-hifi ff410000.codec-1] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: rockchiprk3328 [rockchip,rk3328], device 2: ff030000.spdif-dit-hifi dit-hifi-2 [ff030000.spdif-dit-hifi dit-hifi-2] Subdevices: 1/1 Subdevice #0: subdevice #0 Regards, Dan
  4. Maybe armbian should include the rtl8814au driver like it does the rtl8812au/88xxau driver so it all works out of the box again?
  5. Hello, More of an FYI for anyone else hitting the same issue. Booted my board up for the first time in a year or two, wifi working fine but then sudo update && sudo dist-upgrade && shutdown -r now Now wifi does not work on the new kernel 5.10. Seems the 8812au driver which has morphed into 88XXau but XX no longer includes 14. Instead there's a new driver git clone https://github.com/aircrack-ng/rtl8814au.git apt install build-essential linux-headers-current-rockchip64 ARCH=arm64 make dkms_install modprobe 8814au Now wifi works again
