Tinker board R2.0 audio problem - hissing, noise

[dmitrich 0]

After some time of continuous working (after 2 days, some time after week), the audio output from jack 3.5 starts hissing, noise (shhhhhhh) .
Whether it's a youtube video in the browser, or it's my mp3 playlist playing.
Only reboot can help.
I use the Tinker Board Debian 10 V3.0.11 image on my Tinker board R2.0.
I use it as an audio player through jack 3.5.

Before R2.0 I used a regular Tinker board and did not face this problem.
Has anyone encountered a similar problem, what could be the matter?

hello  @dmitrich, 

while we try reproduce the issue, is it ok if we check the pulse log? what is the output when you execute this line?

sudo cat /var/log/syslog* | grep -i pulse

We do have exactly the same issue: while using the jack output, some (we have dozen of then in the wild ) Tinkerboard S R.20 are randomly and suddenly (can be hours or days) outputing a white noise sound.

We are also using the last TinkerOS linux release (based on debian 10.10).

When the problem arises, there is absolutely nothing in the logs.

When using a digital output ( either bluetooth or HDMI ) there's no such problem.

Maybe a problem related to the DAC ?

Is there a plan to resolve this issue or give us any insight into why this is happening or are you leaving this up to the Scooby-Doo gang?

for those who still suffering from this problem.. 

asus send us audio firmware and we are testing it.. and i am sharing it with all you guys.. :))

attached file contains the firmware.. 

and here are the steps came from asus R&D department:

 

Please follow the steps to check the FW version for reference.

a.       Unzip and copy the file to Tinker Board

b.      cd ALC4030U-FW-Tool
sudo chmod a+x ./rt_UAC_utility
sudo ./rt_UAC_utility --status
sudo ./rt_UAC_utility --force 0x49F6_ALC4030U_ASUS_Tinker_Board_0x0BDA_V13_20220718.rfw --reset RST_2_ATTACH
sudo ./rt_UAC_utility --status --reset RST_2_ATTACH
sudo reboot

 

sudo ./rt_UAC_utility –status   => using this command to check the driver  FW version.
