Rock64 No Audio - Solved
#1
I had posted a thread recently requesting assistance to get ayufan Linux configured to support analog (sound) audio from the internal 3.5 mm A/V (headphone) jack. There were apparently a number of Rock64 users interested in this discussion, but there were no respondents offering any suggestions.  

Since then, I came across an excellent document detailing alsa configuration that lead me to implement the following solution in that I can now obtain audio from the Rock64's 3.5 mm headphone jack.

sudo nano /etc/asound.conf

defaults.ctl.card 1
defaults.pcm.card 1
defaults.pcm.device 0


(Control-X to save file)

Note that this configuration has only been tested on stretch-minimal-rock64-0.6.15-175-arm64 but should work on all current ayufan images.  It does not add a volume control to alsamixer, so you'll have to do additional configuration if your application requires a volume control.

Thanks for writing this down, I did a similar config back when I got my first prototype board and testing the DAC audio board as well. I think librelec also has a more advanced config with soft volume controls etc...
Come have a chat in the Pine IRC channel >>

Hi,

Thanks for posting this. I am struggling to get sound out of the cinch outputs on the DAC addon board.
Could one of you post a config, that is supposed to give me sound out of the cinch outputs?

I am currently using this image:

I tried that way with "xenial-minimal-rock64-0.6.22-188-armhf" and "xenial-minimal-rock64-0.6.22-188-arm64", but I did not hear any sound. why?


その方法を"xenial-minimal-rock64-0.6.22-188-armhf"と"xenial-minimal-rock64-0.6.22-188-arm64"で試しましたが、音が出ませんでした。何故?

I've good results following wbecks's solution (debian stretch mate 9.3, 4.4.112-rockchip-ayufan-189).
Here is my list of packages relating to alsa (I don't know which or if any is necessary)
alsa-utils
libao-common
libao4
libasound2
libasound2-data
libasound2-dev
libasound2-plugins
libmatemixer0
libmatemixer-common
libopenal1
pulseaudio

I use VLC 2.2.7.1 to play sound files, setting Audio/audio device to I2S Analog stereo
The output is strong enough to drive a true Sennheiser headset (4 - 400 ohms)
Hope that helps...

Have you tried several headphones ? There are different types of plugs depending on whether there is a microphone or not ...

My headphones are of a standard 3.5 mm jack. Mike is not attached.
speaker-test
Even when I executed the command, I did not hear any sound.
Sorry for my weird English.

I found this on the Change Log for Mainline Kernel 5.5
Quote:And finally rk3328 audio support, sdmmc detection fix and enabled
    of the gpu on rk3399-puma.
Quote:arm64: dts: rockchip: Add RK3328 audio pipelines
Code:
The audio pipelines for HDMI and the analog codec are internal to the
SoC, so it makes sense to describe them at that level such that boards
need only enable the respective nodes for outputs they implement.

How can this rk3328.dtsi file be used to fix Audio on the Rock64 ?
