Armbianmonitor:

today I compiled a image for my OPi One:
 

Armbian Buster with Linux 5.4.2-sunxi
package bsp-kernel[19.11.3.342] u-boot[19.11.3] dtb[19.11.3.342] 
firmware[19.11.3] config[19.11.3]
branch[dev]

but mpg123 is playing a 128kb/s Radio-Stream much too fast via HDMI (hw:0,0) -

streaming the same URL via a USB-Audio-Dongle (hw:1,0) has the right speed :(

 

Spoiler

Display output (from the numbers) is the same, but with HDMI the buffers gets empty too fast because of the wrong speed...

Does have anybody also this issue?

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...

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.

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

@nylonatathep Thanks for the solution ;) 
I can confirm it also for the Orange Pi One

 

DTB to DTS:
dtc -I dtb -O dts /boot/dtb/sun8i-h3-orangepi-one.dtb -o /boot/dtb/sun8i-h3-orangepi-one.dts

DTS to DTB:
dtc -I dts -O dtb /boot/dtb/sun8i-h3-orangepi-one.dts -o /boot/dtb/sun8i-h3-orangepi-one.dtb

Kernel:
Linux opi-one 5.5.0-rc2-sunxi #19.11.5 SMP Tue Dec 31 13:30:06 +03 2019 armv7l GNU/Linux

PS: as usual - the corrected .dtb gets lost via a apt upgrade if you doesnt set it on hold :(

apt-mark hold linux-dtb-dev-sunxi
