From the architecture side the A64 because A64 => Cortex A53 Core's => 2,24 DMISP/MHz H3 => Cortex A7 Core's => 1,9 DMIPS/MHz Now it depents on the clockrate... (...and the software optimisation) https://en.wikipedia.org/wiki/Comparison_of_ARMv8-A_cores https://en.wikipedia.org/wiki/Comparison_of_ARMv7-A_cores

Problem solved! The dtb file is wrong on newer Kernels after 5.3.9 There is an added option called dai-tdm-slot-width (description) in the sound category which is set to high (0x20). When you set this to 0x10 (decimal 16, I think 16Bit for audio!?) the Sound is in normal speed. There is another typo, I think, in line 897 phy-names is set to "phy" but the name of the phy is "hdmi-phy" so its in old dtb's too. Corrected dts for Orange Pi PC in attachment. Please test this on other boards... EDIT: Confirmed on sunvell R69 1.3 with Kernel 5.5.0cr2 Regards devicetree-5.4.8.dts

The Problem occours on my Orange Pi PC too. (Downloaded Bionic Desktop image with Kernel 5.4.8). But when i switch to current-sunxi 19.11.3 Kernel 5.3.9 audio over HDMI and 3,5mm is OK.

I have the same issue on sunvell r69 Kernel 5.5.0rc2 with every audio (Browser, mpv, etc...); USB Soundcard is OK But the dtb seems to be ok in comparsion with your old dtb provided in the r69 topic...

USB on the back does not work => Information: I compiled Armbian (Bionic, 5.5.0rc2) and tested it on my r69 h2 ver. 1.3 blue PCB with nothing special. Everything works fine except the USB on the back. After some investigation I checked the dtb file and there is the back-USB port configured as OTG. I dont' know if is this a bug or a feature but if you want to use both USB you have ti change the dtb file. After decompile change line 322 in dtb from "otg" to "host", compile it again and replace the orginal file in /boot I added the corrected dts and the compiled dtb file for Kernel 5.5.0rc2. sun8i-h2-plus-sunvell-r69.dtb sun8i-h2-plus-sunvell-r69.dts

Okay, succsess! The images are okay for LaFrite. Was my fault There was an error message that only appeared on screen not on UART messages. That message says that one module file cannot be loaded (bad ELF header)... After some investigaton I testet my USB drive's an both of them have some bad sectors and these are not affected when I flash a minimal image. I think they are corrupted between the many new flashes by testing the images. When I use an new USB drive erverything is booting correctly with 5.3 and 5.4 Images but with 5.4 there is no Audio. Thanks for your work and the help with the console output etc.

Okay that makes sense, i thought the log was very short^^ Armbian_5.99_Rk3399-tv_Debian_buster_dev_5.3.0_desktop_20191123 Here is the log, same error on other x905x dtb's. hwacom and khadas dtb does not boot at all no log. hope it helps output_2019-11-23_11-45-27.log

Same with meson-gxl-s805x-p241.dtb I added the log from armbian 19.11.3 Kernel 5.3.11 too Armbian_5.99_Aml-g12_Debian_buster_default_5.3.0_20191122 boots Armbian_5.99_Aml-g12_Debian_buster_default_5.3.0_desktop_20191122 ended up with kernel panic output_2019-11-23_09-22-34.log armbian19.11.3.log Armbian_5.99_Aml-g12_Debian_buster_default_5.3.0_desktop_20191122.log Armbian_5.99_Aml-g12_Debian_buster_default_5.3.0_20191122

Dev 20191118 and Next 20191119 on LaFrite (meson-gxl-s805x-libretech-ac.dtb) r5 Firmware No boot, stucks at Starting kernel ... Official Armbian boots up.

Tested with Nexbox A95X S905x 1GB (meson-gxl-s905x-nexbox-a95x.dtb) and Magicsee N5 S905x 2GB (meson-gxl-s905x-p212.dtb) and Buster Desktop Image Dev 20191118 on both Boxes boot OK HDMI Sound OK 3D Acceleration OK (glxgears) LAN OK Wifi on A95X (RTL8189ETV) no Adapter etc. found Wifi on N5 (QCA9377) is found but dmesg says "ath10k_sdio...Unsupported hardware version: 0x5020001" BT on N5 not found Next 20191119 on booth Boxes boot OK HDMI Sound - No Sound 3D Accreleration OK LAN OK Wifi on A95X (RTL8189ETV) no Adapter etc. found Wifi on N5 (QCA9377) is found but dmesg says "ath10k_sdio...Unsupported hardware version: 0x5020001" BT on N5 not found

I know the wip status but I was so impressed that nearly everything is working that I tested The same problem with sound was on libre's first release image and was fixed on second but they don't write a changelog or someting

A very thank you to TonyMac32 and the great Armbian comunity! I've compiled the desktop image with no special options (just select the target) and everything is running very nice. The CPU clock is set to max 1.5 GHz, slightly overclocked but it runs without headsink around 50-60 °C on high loads the temperatur rise up to around 65-68 °C in my case. OpenGL (glxgears) and Gles2 (es2gears) runs fine, even the WebGL in Chromium is supported. Video is not HW accelerated in included mpv and Chromium, I think there are any patches needed, but its ok at the moment. I have only one problem, there is no audio. Only the DummyOutput is present. aplay -l says no soundcards found... dmesg has no message related to "sound" or "audio". USB soundcard works pretty well but is not that great experiene Can someone give me a hint to get sound working? load missing modules etc.? For easy testing, the image i compiled can be downloaded here (7zip file): https://drive.google.com/open?id=1Xl-4_R1aolxJMZFqlZdb0voNxOxbJ4PC regards
